Проектор benq dlp texas instruments инструкция

Вступление

Компания BenQ является одной из самых популярных на рынке проекторов. Производитель выпускает много моделей различного предназначения, включая офисные, портативные, для учебных заведений, а также для домашних кинотеатров и даже геймерские. Каждый сможет выбрать модель под собственные потребности и предпочтения.

Практически все модели имеют некоторые общие черты, начиная от технических особенностей и заканчивая способами подключения и настройкой. Большинство проекторов имеют схожее меню, поэтому, прочитав наше сегодняшнее руководство, вы сможете подключить и настроить любой проектор BenQ.

Подключение к компьютеру

В качестве единственного монитора

Начнём с самого простого способа подключения проектора к компьютеру — в качестве единственного монитора. То есть, вместо жидкокристаллического экрана вы будете выводить видеосигнал на проектор. Для этого вам нужно:

1. Убедиться, что все необходимые кабели и разъёмы в наличии и работает исправно. В зависимости от того, насколько новый компьютер и какая видеокарта установлена, можно выполнить подключение через HDMI или VGA. Лучше же, конечно, отдать предпочтение HDMI, поскольку качество передаваемого сигнала будет на самом высоком уровне. Кроме того, можно передавать даже звук, если проектор имеет встроенный динамик.
2. Подключить шнур к разъёму компьютера и проектора соответствующей стороной.
3. Включить проектор и подождать, пока он найдёт входящий видеосигнал.
4. Если проектор не находит сигнал самостоятельно, на пульте управления нажмите кнопку Source либо же кнопку выбора конкретного интерфейса, если на вашей модели для этого имеются отдельные клавиши.
5. Обычно проблемы с разрешением кадра не возникает, но если картинка выглядит растянутой или мелкие детали на ней выглядят неразборчиво, в настройках Windows нажмите правой кнопкой мыши на пустом рабочем столе, после чего выберите пункт «Параметры экрана», из предложенного списка выберите разрешение, на котором работа с проектором будет наиболее комфортной.

   

   Если источник изображения не найден автоматически, установите его с помощью кнопки Source

В качестве дополнительного монитора

Если вы пользуетесь ноутбуком либо же экран компьютера маленький и вы хотите вывести картинку через проектор на экран гораздо большего размера, подключите его в качестве второго дисплея. Как это сделать?

1. Подключите проектор с помощью HDMI или VGA.
2. Перейдите в настройки экрана Windows. В XP для этого нужно кликнуть правой кнопкой мыши на рабочем столе и выбрать «Свойства». В Windows 7 или 8 — «Разрешение экрана».
3. Включите питание на проекторе, и вы должны увидеть, что система определила второй монитор. В Windows XP нужно перейти во вкладку «Параметры» окна настроек экрана, кликнуть на второй монитор, затем чуть ниже поставить галочку напротив пункта «Расширить рабочий стол на этот монитор», выбрать его разрешения, после чего нажать кнопку «Применить». В Windows 7 или 8 также нужно выделить подключённый второй экран, после чего В меню «Несколько экранов» выбрать желаемый вариант подключения из списка. В конце подтвердите выбор кнопкой «Применить». При работе с Windows 8.1 и 10 достаточно нажать комбинацию кнопок Win + P и выбрать желаемый режим подключения из бокового меню. Если же наблюдаются какие-то проблемы с разрешением, его можно поправить в настройках.

Что означает каждый режим подключения?

• Только экран компьютера. Второй экран не используется.
• Расширить. Второй экран является продолжением первого и для того, чтобы отобразить на нём что-то, нужно перетащить на него окно программы.
• Дублировать (повторяющийся). На обоих экранах отображается одинаковая картинка.
• Только второй экран. Экран ноутбука или первый экран компьютера не используется, а изображение выводится только на проектор.

Подключение других источников видеосигнала

Подобным образом можно подключить любое другое устройство с видеовыходом. Для этого можно использовать как новые стандарты HDMI или VGA, так и аналоговые интерфейсы предыдущего поколения. Главное, чтобы соблюдался основной принцип — подключение в правильные разъёмы.

Воспроизведение звука

Некоторые модели проекторов Бенк обладают встроенным звуковым динамиком. Чтобы воспроизводить звук с его помощью, достаточно воспользоваться HDMI либо же подключить аудиокабель в разъем Audio In, по которому сигнал будет поступать из выходов звуковой карты компьютера или тюнера, спутникового ресивера или дискового проигрывателя.

Настройка проектора BenQ

Разобравшись, как подключить проектор BenQ, давайте перейдём к его настройке. Меню настроек поделено на несколько групп, разделённых вкладками: базовые и расширенные настройки изображения или дисплея, управление проекцией, настройки системы, расширенный настройки и общая информация. Последняя вкладка носит большие информационный характер и на работу проектора практически не влияет.

Передвигаться по меню очень просто при помощи пульта управления. Перевод на русский очень качественный, у вас вряд ли возникнут вопросы, даже когда будут встречаться какие-то сокращения. Шрифт крупный и удобочитаемый, что не может не понравиться людям, имеющим проблемы со зрением. Вызывается меню нажатием специальной кнопки на пульте дистанционного управления. Давайте теперь обратим внимание на основные настройки проектора для комфортного просмотра.

Настройка изображения

Если вы устанавливаете мультимедиапроектор на потолок, он получается подвешенным вверх ногами и соответственно изображение на экране изначально также вверх ногами. Чтобы перевернуть изображение на 180 градусов, вам нужно перейти в подменю Настройки системы — Положение проектора. Здесь вам следует выбрать параметр «Спереди — потолок» либо аналогичный. После этого картинка сразу же будет отображаться как положено.

Кроме того, в пунктах меню «Дисплей» («Изображение») и «Расширенные настройки дисплея» («Расширенные настройки изображения»), можно отредактировать следующие параметры:

• Формат видеосигнала.
• Яркость, контрастность, цветность, тон и резкость.
• Уровень чёрного. Этот параметр следует выставить на уровне 0 IRE и больше никогда не менять.
• Контроль резкости. Позволяет выполнить точную настройку подавление посторонних шумов, а также достичь более точного отображения мелких деталей.
• Цветовая температура. Даёт возможность настроить соотношение цветов для более комфортного просмотра в разное время суток.

В этом разделе параметров могут присутствовать пункты, характерные конкретным моделям проекторов. Советуем настраивать их лишь после внимательного изучения руководства пользователя.

Управление проекцией

От этого параметра сильно зависит, каким вы будете видеть изображение на вашем экране. Следует также вспомнить, что на большинстве проекторов BenQ имеется качелька управления вертикальной и горизонтальной проекцией. Это может пригодиться, если кадр немного не совпадает с экраном. Правильно настроенный девайс будет отображать картинку без искажений. Помимо этого, можно настроить следующие параметры:

• Формат. На выбор предлагается соотношение сторон 4:3, 16:9, а также Letterbox и некоторые другие, если они представлены в вашей модели проектора. Кроме того, можно настроить сжатие 16:9 к 4:3 и растянуть картинку в обратном направлении.
• Трапецеидальность. Настроить отклонение по вертикали и горизонтали через меню проектора. Особенно удобно при потолочной установке, когда лезть под потолок, чтобы вручную настроить установленный проектор, не совсем удобно.
• Настройка нерабочей области. Позволяет уменьшить искажения по краям экрана путём обрезания кадра.

Настройки системы

В этом разделе меню проектора можно настроить такие параметры:

• Язык. По умолчанию проекторы, продающиеся в России, имеют русский язык меню, вы же можете поменять его на другой.
• Начальный экран. Картинка, которую вы будете видеть при включении проектора.
• Положение проектора. Как уже упоминалось выше, позволяет выбрать, как именно установлен проектор и поворачивать изображение соответствующим образом.
• Таймер сна. Автоматическое выключение после какого-то периода бездействия.
• Цвет фона. При отсутствии сигнала вы будете видеть сплошной цвет.
• Источник сигнала. Выбор интерфейса, по которому поступает видеосигнал.
• Автоматический поиск источника сигнала.

В расширенном меню настроек можно дополнительно настроить:

• Настройки лампы.
• Настройки
• Скорость передачи.
• Режим большой высоты. Стоит активировать, если вы живете в гористой местности на высоте более 1500 метров над уровнем моря.
• Настройки безопасности.
• Сетевые настройки.

Часто задаваемые вопросы

Наша служба поддержки выполняет поиск полезной информации по изделиям и отвечает на часто задаваемые вопросы. Если вы заметили неточность в наших часто задаваемых вопросах, сообщите нам об этом с помощью нашей контактной формы.

Могу ли я выключить проектор сразу после использования? Проверенный
После использования проектора лампа все еще очень горячая. Лучше всего оставить проектор включенным после использования, чтобы дать внутреннему вентилятору время успеть поработать и охладить лампу. Это продлит срок службы лампы.

Что такое коррекция трапецеидальных искажений? Проверенный
Часто проектор нельзя разместить прямо напротив экрана или стены. Из-за этого проецируемое изображение может искажаться. Это эффект трапецеидального искажения. Коррекция трапецеидальных искажений — это функция, устраняющая это искажение. Не все проекторы предлагают коррекцию трапецеидальных искажений.

Это было полезно (102)

Что такое контрастность? Проверенный
Контрастность показывает, насколько самая светлая точка белого цвета отличается от самой темной точки черного цвета. Например, контрастность 400:1 означает, что самая темная точка черного цвета на экране в 400 раз темнее самой светлой точки белого цвета. Чем выше контрастность, тем выше резкость изображения.

Introduction 11

Positioning your projector

Choosing a location

Your projector is designed to be installed in one of four possible installation locations:

1.

Table in front of screen;

2.

Ceiling in front of screen;

3.

Table at rear of screen;

4.

Ceiling at rear of screen.

1.

Front Table

Select this location with the projector placed near the floor in front of the screen. This is the most common way to position the projector for quick setup and portability.

2.

Front Ceiling

Select this location with the projector suspended upside-down from the ceiling in front of the screen.

Purchase the BenQ Projector Ceiling Mounting Kit from your dealer to mount your projector on the ceiling.

Set in the Advanced > Mirror menu after you turn the projector on.

3.

Rear Table

Select this location with the projector placed near the floor behind the screen.

Note that a special rear projection screen is required.

Set in the Advanced > Mirror menu after you turn the projector on.

4.

Rear Ceiling

Select this location with the projector suspended upside-down from the ceiling behind the screen.

Note that a special rear projection screen and the

BenQ Projector Ceiling Mounting Kit are required for this installation location.

Set in the Advanced > Mirror menu after you turn the projector on.

Your room layout or personal preference will dictate which installation location you select.

Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment.

12 Positioning your projector

Safety instructions for ceiling mounting of the projector

We want you to have a pleasant experience using your BenQ projector, so we need to bring this safety matter to your attention to prevent possible damage to person and property.

If you intend to mount your projector on the ceiling, we strongly recommend that you use a proper fitting BenQ projector ceiling mount kit and that you ensure it is securely and safely installed.

If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that the projector may fall from the ceiling due to an improper attachment through the use of the wrong gauge or length screws.

You can purchase a BenQ projector ceiling mount kit from the place you purchased your

BenQ projector. BenQ recommends that you also purchase a separate Kensington lock compatible security cable and attach it securely to both the Kensington lock slot on the projector and the base of the ceiling mount bracket. This will perform the secondary role of restraining the projector should its attachment to the mounting bracket become loose.

Positioning your projector 13

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size.

The native resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 aspect ratio

(expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the projector’s native aspect width. This will result in a proportionally smaller height equivalent to 75% of the projector’s native aspect height.

14

4:3 aspect image in a 4:3 aspect display area

16:9 aspect image scaled to a 4:3 aspect display area

Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed by this projector. This will be seen as darkened (unlit) bars along the top and bottom

(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a scaled 16:9 aspect image in the vertical center of the 4:3 projection display area.

When determining the position of your projector, you should consider its intended use and input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height than that of the scaled 16:9 aspect image projection area).

IMPORTANT: Do not select a permanent projector position based upon a 16:9 projection if you will ever need to select an input (other than composite Video being fed a 16:9 aspect signal).

The projector should always be placed horizontally level (like flat on a table), and positioned directly perpendicular (90° right-angle square) to the horizontal center of the screen. This prevents image distortion caused by angled projections (or projecting onto angled surfaces).

The modern digital projector does not project directly forward (like older style reel-to-reel film projectors did). Instead, digital projectors are designed to project at a slightly upward angle above the horizontal plane of the projector. This is so that they can be readily placed on a table and will project forward and upwards onto a screen positioned so that the bottom edge of the screen is above the level of the table (and everyone in the room can see the screen).

If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects at a slightly downward angle.

You can see from the diagram on page 16 , that this type of projection causes the bottom edge of the projected image to be vertically offset from the horizontal plane of the projector.

When ceiling mounted, this refers to the top edge of the projected image.

If the projector is positioned further away from the screen, the projected image size increases, and the vertical offset also increases proportionately.

When determining the position of the screen and projector, you will need to account for both the projected image size and the vertical offset dimension, which are directly proportional to the projection distance.

BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the ideal location for your projector. There are two dimensions to consider, the perpendicular horizontal distance from the center of the screen (projection distance), and the vertical offset height of the projector from the horizontal edge of the screen (offset).

Positioning your projector

How to determine the position of the projector for a given screen size

1.

Select your screen size.

2.

Refer to the table and find the closest match to your screen size in the left columns labelled ‘4:3 Screen Diagonal’. Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled ‘Average’.

This is the projection distance.

3.

On that same row, look across to the right column and make note of the vertical Offset value. This will determine the final vertical offset placement of the projector in relation to the edge of the screen.

4.

The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the distance from the screen determined in step 2 above, and offset by the value determined in step 3 above.

For example, if you are using a 120 inch screen, the average projection distance is 4467 mm and with a vertical offset of 183 mm.

If you place the projector in a different position (to that recommended), you will have to tilt it down or up to center the image on the screen. In these situations, some image distortion will occur. Use the Keystone function to correct the distortion. See «Correcting keystone» on page 29 for details.

How to determine the recommended screen size for a given distance

This method can be used for situations where you have purchased this projector and would like to know what screen size will fit in your room.

The maximum screen size is limited by the physical space available in your room.

1.

Measure the distance between the projector and where you want to position the screen. This is the projection distance.

2.

Refer to the table and find the closest match to your measurement in the average distance from screen column labelled ‘Average’. Check that your measured distance is between the min and max distances listed on either side of the average distance value.

3.

Using this value, look across that row to the left to find the corresponding screen diagonal listed in that row. That is the projected image size of the projector at that projection distance.

4.

On that same row, look across to the right column and make note of the vertical Offset value. This will determine the final placement of the screen in relation to the horizontal plane of the projector.

For example, if your measured projection distance was 4.5m (4500mm), the closest match in the Average column is 4593 mm. Looking across this row shows that a 3000 mm (3 m) screen is required. If you can only obtain imperial sized screens, the listed screen sizes on either side of the 3 m screen are the 9′ and 10′ screens.

Checking the min and max projection distance values for these screen sizes, indicates that the 4.5 m measured projection distance will need to be reduced to fit the 9′ size screen, or increased to fit the 10′ size screen. The projector can be adjusted (using the zoom control) to display on these different screen sizes at those projection distances. Be aware that these different screens have different vertical offset values.

There is 3% tolerance among these numbers due to optical component variations. BenQ recommends that if you intend to permanently install the projector, you should physically test the projection size and distance using the actual projector in situ before you permanently install it, so as to make allowance for this projector’s optical characteristics. This will help you determine the exact mounting position so that it best suits your installation location.

Connecting Video source devices

This section describes how to connect the projector to Video source devices using video cables. Video cable connections are recommended for Video presentations.

This projector also supports data (graphic) «PC» connection using wireless function. Wireless connection is not recommended for Video presentations. See «Wireless connection

(optional)» on page 17 .

You can connect your projector to various Video source devices that provide any one of the following output sockets:

• DVI

• Component Video

• S-Video

• Video (composite)

You need only connect the projector to a Video source device using just one of the above connecting methods, however each provides a different level of video quality. The method you choose will most likely depend upon the availability of matching terminals on both the projector and the Video source device as described below:

Best video quality

The best available video connection method is DVI. If your source device is equipped with a

DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end analog video quality.

See «Connecting a Component Video source device» on page 21 for how to connect the projector to a DVI source device and other details.

If no DVI source is available, the next best video signal is Component Video (not to be confused with composite Video). Digital TV tuners and DVD players output Component

Video natively, so if available on your devices, they should be your connection method of choice in preference to S-Video or (composite) Video.

See «Connecting a Component Video source device» on page 21 for how to connect the projector to a component video device.

Better video quality

The S-Video method provides a better quality analog video than standard composite Video.

If you have both composite Video and S-Video output terminals on your Video source device, you should elect to use the S-Video option.

See «Connecting an S-Video source device» on page 23 for how to connect the projector to an S-Video device.

Least video quality

Composite Video is an analog video and will result in a perfectly acceptable, but less than optimal result from your projector, being the least video quality of the available methods described here.

See «Connecting a composite Video source device» on page 24 for how to connect the projector to a composite Video device.

Connecting Audio

The projector has a built-in mono speaker which is designed to provide basic audio functionality accompanying data presentations for business purposes only. It is not designed for, nor intended for stereo audio reproduction use as might be expected in home theatre or home cinema applications. Any stereo audio input (if provided), is mixed into a common mono audio output through the projector speaker.

Connection

If you have a separate sound system, you will most likely want to connect the audio output of your Video source device to that sound system, instead of to the mono audio projector.

The audio connections illustrated in the following sections are provided for informational purposes only. You need not connect audio to the projector if there is an alternate sound system available, or if audio is not required.

Connecting a Component Video source device

Examine your Video source device to determine if it has a set of unused Component Video output sockets available:

•

• If so, you can continue with this procedure.

If not, you will need to reassess which method you can use to connect to the device.

To connect the projector to a Component Video source device through a

Component Video to VGA (D-Sub) adaptor cable:

• With a Component Video to VGA

(D-Sub) adaptor cable:

1.

Take the (optional accessory)

Component Video to VGA (D-Sub) adaptor cable and connect the end with 3 RCA type connectors to the

Component Video output sockets of the Video source device. Match the color of the plugs to the color of the sockets; green to green, blue to blue; and red to red.

2.

Connect the other end of the

Component Video to VGA (D-Sub) adaptor cable (with a D-Sub type connector) to the D-SUB/COMP IN socket on the projector.

•

1.

With a DVI cable:

Take a DVI cable and connect one end of the cable to the DVI output socket of the Video source device.

2.

Connect the other end of the cable to the DVI-I socket on the projecto r.

Selecting the aspect ratio

The ‘aspect ratio’ is the ratio of the image width to the image height. Most analog TV and computers are in 4:3 ratio, which is the default for this projector, and digital TV and DVDs are usually in 16:9 ratio.

With the advent of digital signal processing, digital display devices like this projector can dynamically stretch and scale the image output to a different aspect than that of the image input source.

You can change the projected image ratio (no matter what aspect the source is) by entering

Pro-Picture > Aspect Ratio

. Select an aspect ratio to suit the format of the video signal and your display requirements. There are three aspect ratios available:

In the pictures below, the black portions are inactive areas and the white portions are active areas.

1.

Native: The image is projected at its original aspect ratio, and resized to fit within the display area. For input signals with lower resolutions, the projected image will display smaller than if resized to full screen. You could adjust the zoom setting or move the projector towards the screen to increase the image size if necessary.

You may also need to refocus the projector after making these adjustments.

2.

4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 images like computer monitors, standard definition TV and 4:3 aspect DVD movies, as it displays them without aspect alteration.

3.

Lamp information

Calculation of lamp hour

When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows:

Total (equivalent) lamp hour

= (hours used in Economic mode) + 4/3 (hours used in normal mode)

See «Economic Mode (off)» on page 44 for more information on Economic mode.

The lamp hour in Economic mode is calculated as 2/3 of that in normal mode. That is, using the projector in Economic mode helps to extend the lamp life by 1/3.

Warning message

When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector and in some instances the lamp may explode.

For more detailed information on projector warnings, please refer to «Indicators» on page

Компания Texas Instruments — монополист в области производства DLP-чипов и обслуживающей их электроники, — предложив гибкую технологию BrilliantColor (см. описание тут), фактически дала возможность производителям проекторов экспериментировать с сочетанием сегментов различных цветов в светофильтре и с режимами обработки переходов между сегментами. Про BenQ W5000 мы выяснили, что у него в светофильтре из семи один сегмент прозрачный, и он, а также промежутки между некоторыми сегментами задействуются при включении BrilliantColor. Для BenQ W6000 заявлен светофильтр из шести сегментов. Попробуем определить их цвета и как они используются при формировании изображения.

Вынесены на отдельную страницу.

Внешний вид

Корпус проектора изготовлен из черного пластика с зеркально-гладкой неустойчивой к царапинам поверхностью (передняя, верхняя и задняя панели) и матовой (бока и днище). Взгляд приковывает огромный объектив. Не сразу понимаешь, что собственно фронтальная линза объектива совсем небольшого диаметра, а внешний размер объектива задают диски, изготовленные из пластика с блестящим металлическим покрытием. Эта дизайнерская находка придает проектору дополнительную солидность, если не сказать помпезность. Центральную часть верхней панели с заходом на переднюю занимает пластиковая серо-серебристая вставка ламинированная износоустойчивой пленкой. На верхней панели в обрамлении сиреневого кольца находятся кнопки управления и индикаторы состояния.

Разъем питания и интерфейсные разъемы расположены в неглубокой нише на задней панели.

Чтобы было проще читать подписи к разъемам и при потолочном размещении каждый разъем подписан дважды, вторая подпись перевернута на 180 градусов. Также на задней панели можно обнаружить разъем для замка Кенсингтона. ИК-приемников два: спереди и сзади. На правом боку — крышка отсека лампы.

Воздух для охлаждения забирается через решетки на боковых панелях и на днище, а выдувается через правую фронтальную решетку (вперед и вправо), левая фронтальная решетка — декоративная.

Все 4 ножки немного (примерно на 12 мм) выкручиваются из корпуса, что позволяет выровнять положение проектора, поставленного на горизонтальную поверхность. Для крепления потолочного кронштейна в днище проектора вделаны 4 металлические втулки с резьбовыми отверстиями. Лампу можно менять, не снимая проектор с кронштейна.

Пульт

Пульт почти точно такой же, что и от модели BenQ W5000. Все различие заключается в функциях нескольких кнопок, немного отличающихся обозначениях и в том, что теперь включение и выключение проектора разнесено на две кнопки. При этом проектор не запрашивает подтверждения на выключение, что удобно при программировании универсальных пультов. Пульт относительно большой, его корпус изготовлен из белого пластика с гладкой относительно устойчивой к царапинам поверхностью. Сверху прозрачный пластик прикрывает серебристую подкладку. Кнопочки располагаются свободно, что позволяет находить самые нужные на ощупь. Обозначения несколько мелковаты. Есть яркая светодиодная подсветка, включающаяся кнопкой LIGHT (почему-то не фосфоресцирующей).

   

Коммутация

Набор видеовходов стандартный для данного класса проекторов.VGA-разъем (mini D-sub 15 pin) принимает VGA-RGB- и компонентные цветоразностные сигналы. Видеовходы по циклу перебираются кнопкой SOURCE на корпусе или непосредственно выбираются 6-ю кнопками на пульте или в меню.

Есть функция автоматического поиска активного подключения. Экран с электрическим приводом можно подключить к выходу TRIGGER. Интерфейс RS232, по всей видимости, позволяет дистанционно по проводам управлять проектором. USB-интерфейс предназначен для использования в сервисных целях.

Меню

Меню достаточно крупное, шрифт удобочитаемый. Навигация удобная и быстрая. При изменении параметров, влияющих на изображение, страница с настройками остается на экране, что затрудняет оценку происходящих изменений. Однако при прямом вызове ряда настроек кнопками пульта на экран выводится только небольшое окошко с параметром. Настраивается положение меню и таймаут автоматического выхода из меню. При повторном вызове меню пользователь оказывается на той странице, к которой обращался перед этим. Есть русская версия, русификация хорошая (но некорректное название пункта Режим фотосъемки так и осталось).

Управление проекцией

Фокусировка изображения на экране и регулировка увеличения производятся вращением двух широких ребристых колец на объективе. С помощью джойстика, расположенного рядом с объективом, объектив можно сдвигать в вертикальном (диапазон +/-75% от высоты проекции) и горизонтальном (+/-41,3% от ширины проекции) направлениях.

Граница допустимого положения объектива представляет собой подобие ромба, т.е. при сдвиге по горизонтали диапазон сдвига по вертикали уменьшается и наоборот. Цифровая коррекция вертикальных и горизонтальных трапецеидальных искажений имеет диапазон +/-30°.

Для облегчения настройки проекции при отсутствии входного сигнала на экран можно вывести тестовый шаблон. Режимов геометрической трансформации 5: Анаморф. — для просмотра анаморфированных фильмов и сигналов с форматом 16:9, 4:3 — для просмотра фильмов в формате 4:3, Формат Letter box — для формата Letterbox, Шир. — еще один вариант просмотра фильмов 4:3, но уже во весь экран 16:9 с растяжением картинки минимальным в центре и увеличивающимся к краям, и Реальн. — в котором отключена интерполяция к разрешению матрицы.

В случае компонентных сигналов и VGA в небольших пределах можно сдвигать изображение вверх-вниз и вправо-влево. Режим Формат Letter box можно использовать для проекции через опциональный анаморфотный объектив. Но, учитывая стоимость последнего, вряд ли такая возможность будет кем-либо использована.

Для устранения помех на границах изображения можно включить обрезку краев по периметру (функция Настройка нераб.обл.) за счет небольшого увеличения картинки. Для некоторых аналоговых сигналов минимальная обрезка всегда включена. Есть функция картинка-в-картинке (PIP). Настраивается положение (по углам) и размер (два варианта) дополнительного окна. Четыре кнопки на пульте обеспечивают быстрый доступ к параметрам PIP. На сочетание источников для главного и дополнительного окон накладываются некоторые ограничения.

В меню выбирается тип проекции (фронтальная / на просвет, обычное / потолочное крепление). Проектор длиннофокусный, поэтому при фронтальном проецировании его нужно размещать за зрителями.

Настройка изображения

Исключив стандартные настройки (первая закладка меню), перечислим следующие: Уровень черного (выставить в 0 IRE и забыть),

Контроль резкости (детальная настройка шумоподавления и параметров улучшения контурной резкости),

Температура цвета (без коррекции, 3 предустановленных профиля или 3 пользовательских варианта с регулировкой интенсивности и смещения трех основных цветов),

Выбор гаммы (10 предустановленных профилей), BrilliantColor (разбор работы см. ниже), управление цветом (раздельная двухпараметрическая коррекция шести основных цветов),

Film Mode (включение режима склейки кадра из полей), 3D Comb Filter (функция восстановления цветовой информации при композитном подключении) и Dynamic Black (включение динамической диафрагмы). Включив режим пониженной яркости лампы можно немного уменьшить яркость, а заодно и шум вентиляции. В заводских профилях хранятся предустановленные сочетания значений настроек, еще 3 набора настроек можно сохранить в пользовательских профилях, при желании присвоив им текстовую метку.

Кроме того, изменения в настройках выбранного профиля автоматически сохраняются для каждого видеовхода. Прибегнув к услугам профессионалов можно откалибровать проектор, при этом будут созданы специальные профили цветокоррекции ISF.

Дополнительные возможности

Для исключения несанкционированного использования проектора служат блокировка кнопок на корпусе проектора и на пульте, а также защита паролем доступа к проектору — комбинация из 6-ти нажатий на курсорные стрелки, универсальный пароль в руководстве не приведен.

Есть функция автоматического отключения проектора после заданного интервала (5-30 мин) отсутствия сигнала или просто по истечении заданного периода (30 мин — 3 ч).

Измерения яркостных характеристик

Измерения светового потока, контрастности и равномерности освещения проводились по методике ANSI подробно описанной тут.

Для корректного сравнения данного проектора с другими, имеющими фиксированное положение объектива, измерения проводились при сдвиге объектива вверх примерно на 50% (нижний край проекции находился примерно на оси объектива). Результаты измерений для проектора BenQ W6000 (если не указано обратное, то включен BrilliantColor, выключен Dynamic Black, Температура цвета = Без коррекции и включен режим низкой яркости):

Световой поток
—	2050 лм
Режим высокой яркости	2360 лм
Отключен BrilliantColor	1320 лм
Температура цвета = Норм.	1130 лм
Отключен BrilliantColor и Температура цвета = Норм.	950 лм
Равномерность	+6%, -21%
Контрастность	900:1

Максимальный световой поток немного ниже паспортного значения в 2500 лм. Равномерность освещенности белого поля хорошая. Контрастность очень высокая, но, отметим, что при включенном BrilliantColor и выключенной коррекции цвета. Также мы измерили контрастность, измеряя освещенность в центре экрана для белого и черного поля, т.н. контрастность full on/full off.

Режим	Контрастность full on/full off
—	1890:1
Отключен BrilliantColor	1195:1
Температура цвета = Норм.	1240:1
Отключен BrilliantColor и Температура цвета = Норм.	1040:1
Максимальное фокусное расстояние	2180:1
Включен Dynamic Black	120000:1

Контрастность в ярких режимах высокая, а при использовании динамической диафрагмы она даже больше заявленных 50000:1. Диафрагма представляет собой зеркально-гладкий металлический диск с прорезью переменной ширины, размещенный непосредственно после лампы. При вращении диска прорезь перекрывает окошко выхода света, тем самым регулируется световой поток. При выводе полностью черного поля и при включенном Dynamic Black диск поворачивается так, что свет проходит через самую узкую часть прорези. Ниже приведен график изменения освещенности при переключении с черного поля на белое:

Видно, что полный диапазон отрабатывается примерно за 0,75 с. Это не очень быстро, успеваешь заметить плавное изменение яркости при переходе от темной сцены к светлой и наоборот.

Производитель заявляет, что проектор оснащен светофильтром с шестью сегментами, но при этом не уточняет какие. На самом деле это два красных и два синих примерно одинаковой ширины, широкий зеленый и узкий желтый. Именно за счет желтого сегмента и использования промежутков между сегментами повышается яркость белого поля при включении режима BrilliantColor. Аналогично при включении режима BrilliantColor желтый сегмент участвует в формировании желтого цвета. Ниже приведены графики освещенности желтого и белого поля при отключенном и при включенном BrilliantColor (BC):

Разумеется, увеличение яркости белого и желтого цветов (и некоторых других) относительно, например, чистых красного, зеленого и синего ухудшает цветовой баланс. При выключении режима BrilliantColor баланс выравнивается, а при включении цветокоррекции (параметр Температура цвета) цвета окончательно приходят в норму. Однако при этом сильно понижается освещенность белого поля, а освещенность черного поля практически не меняется, что приводит к значительному снижению контраста. Т.е. перед пользователем всегда стоит дилемма: высокая яркость и контраст или правильная цветопередача.

Судя по графикам, частота чередования сегментов красного и синего цветов составляет 240 Гц при кадровой развертке в 60 Гц и 120 Гц для зеленого сегмента, т.е. светофильтр имеет скорость почти 4x. Эффект «радуги» имеет среднюю заметность. Как и во многих DLP-проекторах для формирования темных оттенков используется динамическое смешение цветов (дизеринг).

Для оценки реального контраста в кадре при различных площадях белых полей мы провели серию дополнительных измерений с использованием набора шаблонов. Подробности описаны в статье про Sony VPL-HW15. Результаты для двух серий измерений на графиках ниже (BC — BrilliantColor, Т.ц. — Температура цвета):

Видно, что по мере увеличения площади белого контрастность падает и приближается к аналогу ANSI, но первая точка (0,1% белого) близка к значению full on/full off. Таким образом, контраст full on/full off можно считать характеристикой реального контраста в кадре при очень небольшой площади белого. В режиме с правильной цветопередачей full on/full off контраст уменьшается примерно в 1,8 раз относительно режима с включенным BrilliantColor и выключенной коррекцией цвета, а контрастность аналогичная ANSI уменьшается не так сильно — примерно в 1,4 раза. Простая модель (приведена в статье про Sony VPL-HW15) опять хорошо согласуется с полученными данными:

Для оценки характера роста яркости на шкале серого мы измерили яркость 256-ти оттенков серого (от 0, 0, 0 до 255, 255, 255). График ниже показывает прирост (не абсолютное значение!) яркости между соседними полутонами:

Тенденция роста прироста яркости сохраняется во всем диапазоне, и каждый следующий оттенок значимо ярче предыдущего, за исключением первого (не отличается от черного) и одного в светлой области шкалы:

Аппроксимация полученной гамма-кривой дала значение показателя 2,17 (при Выбор гаммы = 2.2), что совсем немного ниже стандартного значения 2,2. При этом реальная гамма-кривая хорошо совпала с экспоненциальной функцией (коэффициент детерминации равен 0,9999).

В режиме высокой яркости потребление электроэнергии составило 358 Вт, в режиме пониженной яркости — 317 Вт, в режиме ожидания — 1 Вт.

Звуковые характеристики

Внимание! Приведенные значения уровня звукового давления получены по нашей методике, и их нельзя напрямую сравнивать с паспортными данными проектора.

Режим	Уровень шума, дБА	Субъективная оценка
высокой яркости	37	Тихо
пониженной яркости	34	Очень тихо

Для кинотеатрального проектора уровень шума в режиме с высокой яркостью лампы довольно высокий, но большой запас яркости позволяет отказаться от использования этого режима при просмотре кинофильмов дома, а при пониженной яркости шум снижается до приемлемой величины. Работу динамической диафрагмы слышно в виде приглушенного звука тыр-тыр даже на фоне вентиляции в ярком режиме.

Тестирование видеотракта

VGA-подключение

При VGA-подключении поддерживается разрешение 1920 на 1080 пикселей при 60 Гц кадровой частоты. Оттенки на шкале серого различаются от 0 до 251 с шагом через 1, оверскан отключается, микроконтраст не очень высокий, есть незначительно замыливание.

DVI-подключение

Для тестирования DVI-подключения мы использовали кабель-переходник с DVI на HDMI. Проектор стабильно работает в самом правильном для него разрешении — 1920×1080 при 60 Гц. Качество изображения высокое, пиксели выводятся 1:1. Белое и черное поля равномерные. Бликов нет. Геометрия идеальная. Шкала серого равномерно серая, ее небольшой цветовой оттенок определяется выбранной цветовой температурой. Хроматические аберрации объектива практически отсутствуют, но границы между пикселями немного размыты.

При сдвиге объектива и изменении фокусного расстояния качество изображения существенно не меняется.

HDMI-подключение

HDMI-подключение тестировалось при подключении к Blu-ray-плееру Sony BDP-S300. Поддерживаются режимы 480i, 480p, 576i, 576p, 720p, 1080i и 1080p@24/50/60 Гц. Картинка четкая, цвета после коррекции правильные, оверскан отключается, есть реальная поддержка режима 1080p при 24 кадр/с. Слабые градации оттенков в тенях и на светлых участках изображения хорошо различаются. Яркостная и цветовая четкости всегда очень высокие.

Работа с источником композитного и компонентного видеосигнала

Четкость изображения хорошая. Так как при компонентном подключении в режимах 720p и 1080i всегда включен небольшой оверскан, то четкость картинки в этих режимах немного ниже возможной. Тестовые таблицы с градиентами цветов и со шкалой серого не выявили каких-либо артефактов изображения. Слабые градации оттенков в тенях и на светлых участках изображения хорошо различаются. Цветовой баланс правильный (при отключенном BrilliantColor и Температура цвета = Норм.).

Функции обработки видеосигнала

В случае чересстрочных сигналов проектор пытается правильно составить кадр из смежных полей. Проектор отлично справился как с нашими тестовыми фрагментами с двигающимися мирами (преобразование 2-2 для PAL 25 кадр/с и NTSC 30 кадр/с), так с рядом тестовых фрагментов с диска HQV (NTSC 2-2/30 кадр/с и 3-2/24 кадр/с). В тесте с диска BD HQV и сигнала 1080i, по крайней мере, в простых случаях, также выполнялся правильный деинтерлейсинг.

Функция подавления видеошумов (не включается при Full HD по HDMI) почти полностью подавляет зернистую рябь, и даже на максимальном уровне фильтрации за двигающимися объектами нет видимого хвоста из неубранного шума. Видеопроцессор проектора на неподвижных объектах устраняет характерные цветовые артефакты при композитном подключении. При масштабировании из низких разрешений выполняется качественное сглаживание границ объектов.

Определение задержки вывода

Задержка вывода изображения относительно ЭЛТ-монитора составила около 40 мс при VGA-подключении и 46 мс при HDMI(DVI)-подключении. Задержку в 46 мс в чувствительных к этому параметру случаях (например, в случае динамичных игр) уже можно ощущать.

Выводы

Как и в случае с предыдущей моделью для получения изображения с хорошим качеством цветопередачи нужно отключить BrilliantColor и включить коррекцию цветов. Эти действия уменьшат яркость и в чуть меньшей степени контрастность. Наоборот, оставляя преимущество за яркостью, можно получить почти 2500 лм, что позволит использовать экран очень большого размера (до 6 м по диагонали в полной темноте) или снизить деградацию изображения в условиях не полного затемнения.

Достоинства:

• Хорошее качество изображения
• Хороший видеопроцессор (качественные интерполяция, сглаживание, деинтерлейсинг и подавление видеошумов)
• Сдвиг объектива по горизонтали и по вертикали
• Функция картинка-в-картинке
• Пульт ДУ с подсветкой
• Оригинальный дизайн корпуса
• Русифицированное меню

Недостатки:

• Отчетливо слышно работу динамической диафрагмы
