INTRODUCTION The Knoll HD284 Introduction Congratulations and thank you for your choice of a superior digital image projection device. Your new Knoll HD284 is specifically designed for home cinema applications. The HD284 sets new standards for high-definition digital perfection, featuring true High Definition 1280x720 resolution using the latest DLP™ technology and new DCDi video processing from Faroudja™.
SETTING UP THE PROJECTOR There are a number of factors to consider when determining where to set up the projector, including the size and shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. But here are some general guidelines. NOTE: To ensure adequate cable access, do not place the projector within 6 inches (.15m) of a wall or other object. Position the projector on a flat surface at a right angle to the screen.
HD284 Projection Distances 16:9 Image Screen Diagonal 92” 103” 106” 110” 122.5” 146.75” 165.25” Min. Distance 133.3” 149.6” 153.3” 160” 178.33” 213.33” 214” Max. Distance 166.6” 187” 191.6” 200” 222.9” 266.6 299” Screen Offset 7.3” 8.2” 8.4” 8.8” 9.8” 11.7” 15” Note: Maximum distance to screen (16.9) = 1.816 x screen diagonal size Minimum distance to screen (16.9) = 1.452 x screen diagonal size Screen offset (image drop or rise) (16.9) = 0.
Video Connections 1. Place the projector on a flat surface or using a ceiling mount kit, on the ceiling. If you want to project from behind a rear projection screen, set up the projector behind your screen. 2. Position the projector the desired distance from the screen. The distance from the lens of the projector to the screen and the zoom setting determine the size of the projected image. See the table on page 7 for maximum and minimum distances for a given screen size. 3.
Connecting a Video Device If your video device has more than one output, select the highest quality one. DVI video has the best quality, followed by Component video, S-video, and then composite video. If the video device uses component cable connectors, plug the cable’s green connectors into the green component-out connector on the video device and into the green component connector (labeled “Y”) on the projector.
If the video device uses a VESA connector, plug a VESA cable into the video-out connector on the video device. Plug the other connector into the VESA connector on the projector. Connecting the power cable Connect the power cable to the connector on the back of the projector and to your electrical outlet. The Power LED on the keypad turns solid green. NOTE: Always use the power cable that shipped with the projector. Displaying an Image (Video or Computer) Displaying a video image Remove the lens cap.
If the image is not square, adjust the keystone using the buttons on the keypad. Press the upper Keystone button to reduce the width of the upper portion of the image, and press the lower Keystone button to reduce the width of the lower portion. The Contrast, Brightness, Color, and Tint are factory calibrated to D65 colors, but you can adjust these settings in the Picture menu if necessary. Connecting to a computer Connect either a VESA cable or M1 cable into the appropriate connector on the projector.
Shutting down the projector Power Save The projector has a Power Save feature in the System menu that automatically turns the lamp off after no signals are detected for 20 minutes. After 10 additional minutes with no signal, the projector powers down. If an active signal is received before the projector powers down, the image is displayed. You must press the Power button to display an image after 30 minutes have passed. Turning off the projector To turn off the projector, press the Power button.
The following table shows some potential problems. In some cases, more than one possible solution is provided. Try the solutions in the order they are presented. When the problem is solved, you can skip the additional solutions.
Using the projector keypad buttons Most buttons are described in detail in other sections, but here is an overview of their functions: Power–turns the projector on and off. Menu–opens the on-screen menus. Select–confirms choices made in the menus. Up/down arrows–navigates to and adjusts settings in the menus. Auto image–resets the projector to the source. Presets–cycles through the three available user preset settings. Keystone–adjusts squareness of the image. Brightness–adjusts intensity of the image.
Using the remote control The remote uses two (2) provided AAA batteries. They are easily installed by sliding the cover off the remote’s back, aligning the + and - ends of the batteries, sliding them into place, and then replacing the cover. To operate, point the remote at the projection screen or at the projector (not at the video device or computer). The range of optimum operation is 1 to 30 feet (9.14m). Press the remote’s Menu button to open the projector’s menu system.
Optimizing video images After the video device is connected properly and the image is on the screen, you can optimize the image using the onscreen menus. Change the Aspect ratio. Aspect ratio is the ratio of the image width to image height. TV screens are usually 1.33:1, also known as 4:3. HDTV and most DVDs are 1.78:1, or 16:9. Choose the option that best fits your input source in the menus, or press the Resize button on the remote to cycle through the options.
The menus are grouped by usage: The Picture menu provides image adjustments. The Settings menu provides set-up type adjustments that are not changed often. The About menu provides a readonly display of information about the projector and source. Certain menu items may be hidden until a particular source is connected. For example, Tint is only available for NTSC video sources and will be hidden when other sources are active. Other menu items may be grayed out when they are not available.
Native: this mode bypasses the internal scaler, displaying the image with no resizing. Since the native resolution is 1280x720 and 4x3 video images are approximately 640x480, 4x3 images will always be smaller than the display and will be centered in the display. Computer images 1024x768 or smaller will also be centered in the display. If a 16x9 video source or a 1280x1024 or larger computer source is viewed, it will display up to 1280 pixels and 720 lines from the center of the input.
Natural Wide: this mode stretches a 4:3 image to fill the entire 16:9 screen. The center two-thirds of the image is unchanged; the edges of the image are stretched. Presets: This allows you to customize settings and save the settings to be restored later. To restore the factory default settings, choose Factory Reset in the Settings>Service menu. To set a preset for the current source, adjust the image, select Save Settings in the Presets menu, then choose Save User 1, 2, or 3.
Advanced settings TrueLife: This option refers to Faroudja’s TrueLife processing of the image. All standard definition interlaced video signals (composite, S-video and component) are routed through this processor. Extended and High Definition progressive component sources are not routed though this processor by default. You can turn TrueLife on to route these signals through the processor and then adjust the following 2 options: Chroma Detail: This adjusts the color sharpness.
Color Control: allows you to individually adjust the gain (relative warmth of the color) and the offset (the amount of black in the color) of the red, green, and blue colors. Gamma: Gamma tables contain preset intensity configurations optimized for the input source. You can select a gamma table that has been specifically tuned for either film, video, Bright Room, or PC input.
The Source Enable feature is used to eliminate certain sources from this search, which will speed the search. By default, the check boxes for all sources are checked. Uncheck a source’s box to eliminate it from the search. System All options in this menu toggle between on and off. Rear: reverses the image so you can project from behind a translucent screen. Ceiling: turns the image upside down for ceilingmounted projection.
Blank Screen: determines what color displays when you press the Blank button on the remote or when no source is active. Language: allows you to select a language for the onscreen display of menus and messages. Service Menu Use these features, highlight them and press Select. Factory Reset: restores all settings (except Lamp Hours, Ceiling, and Rear) to their default after displaying a confirmation dialog box. Test Pattern: displays a test pattern when the Blank button on the remote is pressed.
Replacing the projection lamp The lamp hour timer in the About menu counts the number of hours the lamp has been in use. After 1980 hours, the message “Change lamp” briefly appears on the screen at each startup. To maintain optimal video performance, we recommend changing the lamp after 2000 hours, depending on usage. You can order new lamp modules from your dealer. . 1. Turn off the projector and unplug the power cable. 2. Wait 60 minutes to allow the projector to cool thoroughly. 3.
