41 WHAT APPEARS IN CHANNEL SETUP MENU? This menu lists all channels defined so far and indicates where they are connected on the input panel. The far left column lists channel numbers currently defined. The values in the far right columns indicate horizontal and vertical frequencies — if someone has defined a name for this channel, it appears here instead. Remaining columns contain details pertaining to each channel setup, such as its switcher number (always 0 = projector), slot location, a variety of icons indicating access to each channel, and an abbreviated description of each signal type. See Editing a Channel Setup for details. NOTE: If you have more than a handful of channels, use the LEFT and RIGHT arrows to see the remaining channels not visible in the initial display of channels. SIGNAL TYPE — Channel lists [whether the Channel key list or the Channel Setup menu], identify signal types in a shortened form as defined in the table. These descriptors indicate what signal information the projector uses to identify a match for a given channel, and are preceded by either an “i” (interlaced signals) or “p” (progressive signal“). FUNCTIONS WITHIN THE CHANNEL SETUP MENU—To copy, delete or edit a channel, highlight the desired channel in the Channel Setup menu and do one of two things: • Press FUNC if you want to copy the selected channel or delete this or other channels. See Copying or Deleting a Channel for more information. • Press ENTER if you want to edit channel setups (i.e., non‐image related parameters) for the selected channel. See Editing a Channel Setup, on the following pages. TO COPY A CHANNEL, highlight the desired channel in the Channel Setup menu, then press FUNC to go to the Channel Copy/Delete submenu. Select “Copy” and press ENTER — a new channel will be created. It is identical to original, which still remains, but it is identified with the next available number from 01‐99. If you change your mind and do not want to copy the current channel, press Exit to cancel and return to the previous menu. Copying channels is a quick method for creating numerous channels, each of which can then be edited and adjusted for a variety of parameters in the future. Refer to the figure below.
42 TO DELETE A CHANNEL, highlight the desired channel in the Channel Setup menu, then press FUNC to activate the Channel Copy/Delete submenu. Select “Delete” and press ENTER — a confirmation window will appear to make sure that you really want to delete this channel. TO DELETE MULTIPLE CHANNELS, highlight any channel in the Channel Setup menu and press FUNC to go to the Channel Copy/Delete submenu. Select “Delete Unlocked Only” and press ENTER to delete all unlocked channels. Or select “Delete All Channels” to delete all channels, even those that are locked. In either case, the current channel will remain but will be redefined from projector defaults. NOTE: For any deletion, a confirmation box appears to make sure that you really want to delete. Select “Cancel” (default) if you don’t want to delete after all. The basic setups that describe how and where a channel can be accessed are listed in the Channel Setup menu. These channel setups can be edited at any time in the Channel Edit submenu. CHANNEL EDIT — STEP 1 Press Menu from the presentation level to display the main menu. To display the Channel Setup menu, press 3 , or move the highlight to the Channel Setup option and press ENTER . The Channel Setup menu will appear. CHANNEL EDIT — STEP 2 To edit parameters shown in the Channel Setup menu, select the relevant channel and press ENTER . The Channel Edit menu will appear similar to the sample shown above. As desired, review and/or edit the following channel setups in the Channel Edit menu: • CHANNEL NAME: An alpha‐numeric label can be defined and/or changed here. Channel names can be up to 12 characters in length. • CHANNELNUMBER: A 2‐digit channel number can be changed here. NOTES: 1) If you enter a channel number that already exists, a dialog message appears indicating that this number is already in use–assign a different channel number. 2) You can define up to 99 channels.
43 • INPUT: Corresponding to where on the projector’s input panel the source is connected. • IN MENU: If checked (default, except for automatically defined channels with unchanged parameters), this defined channel will then appear in the list available when Channel key is pressed. If unchecked, the channel must be accessed via Channel on the keypad or via the Auto Source function. NO TE: Onscreen display of the channel list is an option that must be set in the Menu Preferences menu. • AUTOSOURCE: If checked, (default), the projector can automatically locate this channel when an incoming input signal matches. If not checked, the projector can locate the selected channel only when it is directly selected via Channel on the keypad — and a change in input signal will not result in a channel change. • LOCKED: If checked, all of the Picture Adjustments for this channel are disabled. If unchecked (default), all available Picture Adjustments can be adjusted as desired. You cannot use Quick Setup with a locked channel. • PREVIOUS CHANNEL: Select this option to see or change Channel Edit settings for the previous channel in the Channel Setup list. • NEXT CHANNEL: Select this option to see or change Channel Edit settings for the next channel in the Channel Setup list. 3.6 Adjusting the Image The most commonly used options for image adjustments are accessed through two menus, both of which appear in the Main menu: Size and Position ( Menu 1 ) and Image Settings ( Menu 2 ),. From either of these two menus, you can change settings affecting the image from the current channel by working with the appropriate slide bars, checkboxes and pulldown lists. Exit will return to the previous menu (or to the
44 presentation, if from the Main menu) and accept any changes you may have entered. Settings are saved with the current channel. For your situation, you can access any of the individual options in these menus by pressing Menu followed by the appropriate two‐digit number representing their location in the menu system. For example, press Menu 2‐3 to quickly access the “Gamma” option in the Image Settings menu. Note that for certain options, you may prefer to use a “direct key” from presentation level to go directly to a particular option without traveling through the menu system (available for certain display parameters only). Before You Begin ‐ Use Quick Setup For a good and efficient first step in perfecting the image, press Quick Setup . This initiates an automated process in which the projector quickly optimizes critical display parameters such as size, position, pixel tracking, etc., based on the type of incoming source data detected. A Quick Setup selection can save considerable setup time, and you can still modify the adjustments as desired using menu options described below. Size and Position In the Size and Position menu, you can increase or decrease the size of your image, change its proportion (aspect ratio), move the image to a specific area of the screen, and refine other related parameters. Use Size and Position controls to match the image precisely to the screen employed. Changes made in the Size and Position menu are applied immediately and are saved when you exit the menu (press Exit or Menu ). Resize Presets Select a Resize Presets option to quickly display an image in its native resolution or to automatically resize an image to closely fill the projector’s native resolution or to optimize the width or height of your display. Size, Position and Blanking parameters will automatically adjust accordingly or, if Blanking is set first, which defines an Active Input Area; Resize Preset scaling will occur in this region of interest only. Resizing options are explained in detail below. WHAT IS THE RESIZING DEFAULT? By default when displaying a new source, your image will utilize as much of the projector’s display area as possible for the type of incoming source data, but with minimal or no changes to aspect ratio. See Select “Default” below. WHEN “CUSTOM” APPEARS: The “Custom” re‐size descriptor automatically appears in the Geometry and Position menu when any of the values for Size, Vertical Stretch, H‐Position, V‐Position or Blanking do not correspond to those for a preset. This option is not offered in the Resize Presets pull‐down list.
45 • Select “DEFAULT” for most sources (factory default). The image will be centered and displayed as large as possible depending on the type of source. • Select “NO RESIZING” to display the image in its native 1920 x 1080 resolution. • Select “FULLSIZE” to use all pixels (1920 x 1080) for displaying the image, regardless of source or original aspect ratio. Incoming source material having a different aspect ratio than the projector will be stretched for display. • Select “FULL WIDTH” to fill the projector’s display from left‐to‐right without changing the original aspect ratio of the image. Depending on the source, data at the top and bottom may be discarded (cropped), or the display may have black borders at the top and bottom (called “Letter Box”). • Select “FULLHEIGHT” to fill the display from top‐to‐bottom. Depending on the source, this may create borders. • Select “LETTER BOX” to display a Letter Box image in its native 16:9 aspect ratio. The image will fill the screen from side‐to‐side and be centered. Size “Size” controls both the image width and height in tandem, maintaining the current aspect ratio (proportion) of the displayed signal data. Vertical Stretch “Vertical Stretch” adjusts the height of the image while keeping the width constant. Use “Vertical Stretch” to change the aspect ratio of the display. Pixel Tracking Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. Proper pixel tracking helps insure that the image quality is consistent across the screen, that aspect ratio is maintained, and that pixel phase can be optimized (described below). Tracking determines the frequency of the pixel sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a particular source are sampled. NOTE: By default, the projector samples at the correct frequency for most sources. For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white pixels, or a similar “half on, half off” graphic image, such as the Windows shutdown screen. Adjust the slidebar until the vertical stripes broaden to the point where one large stripe fills the image. If the image still exhibits some noise, adjust Pixel Phase (below). Pixel Phase [NOTE: Adjust “Pixel Phase” after “Pixel Tracking”]. Adjust pixel phase when the image (usually from an RGB source) still shows shimmer or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming signal.
46 For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white pixels, or a similar “half on, half off” graphic image, such as the Windows shutdown screen. Adjust the slidebar until the image stabilizes and each pixel is clearly defined. You may notice that you can stabilize the image at more than one point — i.e., you may find that the image appearance at “11” is identical to the image appearance at “38”, thus you can use either setting. If some shimmer from a video or HDTV source persists, use the “Filter” control to remove high frequency noise from the signal. See Picture Adjustments. H‐Position This option moves the image right or left within the area of available pixels. NOTE: The value shown represents where the approximate center of the image lies in relation to the total number of pixels available horizontally. This varies widely according to the signal — watch the image while adjusting. V‐Position This option moves the image up or down within the area of available pixels. NOTE: The value shown represents where the approximate center of the image lies in relation to the total number of pixels available vertically. This varies widely according to the signal — watch the image while adjusting. Advanced Size and Position — SUBMENU This submenu consists of the following options: ACTIVE INPUT WINDOW: This read‐only value indicates the current size (i.e., area) of your displayed data or “region of interest” as defined by the blanking controls. By default, the projector automatically determines what portion of its full resolution to use, and pixels in the surrounding borders are turned off. You can also specify a specific active input window size by adjusting one or more “Blank” settings. For example, if you have blanked (cropped) 100 pixels from both the left and right edges of an incoming source of 1920 x 1080, the remaining active input window will be reduced to 1720 x 1080. BLANKING (TOP, BOTTOM, LEFT, and RIGHT): Crop the image as desired so that unwanted edges are removed from the display (changed to black—see right). Blanking defines the size of the Active Input Window, or area of interest. Range of adjustment depends on the source resolution and other factors. After adjustment of blanking it may be necessary to perform a source switch. NOTE: Blanking a PIP image resembles zoom. For example, left Blanking zooms the right side of the PIP image; Right Blanking zooms the left side. There are no black bars. PLUG & DISPLAY (EDID): EDID = Extended Display Identification Data standard.
47 By default, a Plug & Play (EDID) source outputs a signal according to the EDID information provided by the projector. To override this information and display in a different format (for example, if your Plug & Play [EDID] device does not support the projector’s resolution and/ or frequency), select the desired Plug & Play (EDID) resolution from the list. Image Settings Menu Use options in the Image Settings menu to alter your image without affecting its size or position. Changes made to the Image Settings menu are applied immediately and are saved when you exit the menu (press Exit or Menu ). Options not available for the projector model or source are disabled and appear dim (gray). Contrast (SHORT CUT: Press Contrast and adjust the slide bar.) “Contrast” increases or decreases the perceived difference between light and dark areas of your image (0‐100). For best results, keep it around or under 60. If contrast is set too high, the light parts of the image lose detail and clarity. If set too low, the light areas will not be as bright as they could be and the overall image will be dim. For best results, start with a low value and increase so that whites remain bright but are not distorted or tinted and that light areas do not become white (i.e., are “crushed”). NOTE: If the environment lighting changes, an adjustment of Gamma is recommended (see below). Brightness (SHORT CUT: Press Bright and adjust the slide bar.) “Brightness” increases or decreases the amount of black in the image (0‐100). For best results, keep close to or just below 50. Start with a high value and decrease so that dark areas do not become black (i.e., are “crushed”). Conversely, high brightness changes black to dark gray, causing washed out images. Gamma (SHORT CUT: Press Gamma and adjust the slide bar.) “Gamma” is a global setting that determines what gray shades are displayed between minimum input (black) and maximum input (white) for all signals. A good gamma setting helps to optimize blacks and whites while ensuring smooth transitions for the “in‐between” values utilized in other colors. Thus, unlike “Brightness” and “Contrast” controls, the overall tone of your images can be lightened or darkened without changing the extremes, and all images will be more vibrant while still showing good detail in dark areas. Gamma is used to fine‐tune the gamma table currently in use, ranging from 1 – 3 (2.4 = default). If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This will improve contrast while maintaining good details for blacks. Conversely, if the
48 image is washed out and unnatural, with excessive detail in black areas, increase the setting. In high ambient light conditions, lower gamma may produce better results than higher gamma. For more information, refer to Advanced Image Settings submenu, Gamma Table. Again, good gamma improves contrast while maintaining good details for blacks. Filter The proper filter setting is automatically set for virtually all signals, and rarely needs to be changed. It applies a low pass filter for noise reduction in the incoming input signal, particularly for HDTV or SDTV. Applied in the analog domain before sampling, this filtering removes high frequencies and thus reduces pixel phase noise (note this also reduces signal bandwidth). Override only if standard pixel tracking and phase adjustments do not adequately clear up a “noisy” video signal, or if a graphics signal appears overly “soft”. Both instances indicate that “Filter” may be set to the wrong option. Detail “Detail” adjusts the sharpness of a video image so that edges remain clearly defined. It can be particularly useful if a significant “Noise Reduction” adjustment has caused the image to appear too soft. Adjust until the display is as sharp as desired, keeping in mind that because “Detail” adds some high frequencies back into the image, it can also re‐introduce a certain degree of noise. Noise Reduction “Noise Reduction” is similar to the “Filter” control, but operates in the post‐sampling digital domain with a more subtle effect. Higher settings are most useful for clearing up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind that reducing noise (which reduces high frequencies) may also soften the image. Color Space “Color Space” determines how the color components of an analog input signal are decoded for accurate color in the display. Although color space for analog signals is automatically determined by the projector, in some circumstances you may wish to override this and manually set a specific color space. NOTE: For digital signals the color space function is entirely automatic and the pull‐down list disabled. The current color space appears in the Picture Adjustments menu. Press ENTER to select a different option [if available]: • Select RGB unless you are using component video at INPUT 1, 2, 5 or 6. • Select YPbPr (Video) with a standard definition televised signal (SDTV) • Select YPbPr (HDTV) with a high definition televised signal (HDTV). NOTE: When certain RGB signals are first connected, the projector may not initially recognize them as RGB and will incorrectly decode their color information as YPbPr (video). These signals can include: • RGB signals in NTSC, PAL, SECAM frequency ranges • Scan‐doubled sync‐on‐green • Scan‐quadrupled sync‐on‐green
49 For these signals, change the Color Space to RGB, and then define a new channel for future use. Video Options — SUBMENUS This submenu is used with certain video sources only. AUTO COLOR LEVEL: Auto Color Level affects decoded video images only. Enter a checkmark (default) in most instances — this activates the Auto Color Level circuit to insure properly bright images. Delete the checkmark if a decoded video image exhibits strange color artifacts such as stripes in highly saturated colors, indicating an incompatibility between this source and the Auto Color Level. VIDEO STANDARD: For all but the more unusual video standards available in the world, the projector automatically detects the incoming horizontal and vertical frequencies and sets the projector’s processing of this signal to the corresponding standard. The current video standard name appears in the Video Options submenu, and includes an “A” if it has been auto‐detected. Press ENTER to view or select a different video standard from those available to the projector— any that are disabled have frequency characteristics that differ from those of the incoming signal. Selecting a specific standard forces the projector to process the signal according to this standard. NOTE: Best results are obtained with defined channels. Otherwise, switching from one video source to another can sometimes cause slight disturbances in the display, indicating that the Auto function is struggling. Recover by briefly selecting a different video standard, then going back. NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input signal or 2) a black‐and‐white video signal. In order to detect and display such signals, select the relevant standard from the list. INPUT VIDEO BLACK: This control compensates for incoming elevated black levels present in certain video signals, and insures that blacks in the display are neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e., where blacks appear dark gray). By default, the projector automatically determines the best setting according to the type of incoming video signal: • Enhanced 0 IRE – Used for DVD, BR player output with “enhanced black”, SECAM, most PAL standards, and Japanese NTSC. • Video 7.5 IRE – Used for most NTSC video signals.
50 For some types of video, you can override the setting. The control is disabled for other types of video (and all graphics sources). Generally, if black appears crushed when brightness = 50, choose “Enhanced 0 IRE”. If black appears excessively elevated, use “Video 7.5 IRE”. COLOR: This slidebar adjusts the Color Temp Adjust level, i.e. the amount of color in a video image. Lower settings produce less saturated colors — for example a setting of “0” produces a black and white image. If the color level is too high, colors will be overpowering and unrealistic. TINT: This slidebar adjusts the red/green color hue for true color reproduction of video signals connected to INPUT 3 or 4 of the projector. For best results, adjust tint while displaying an external color bars test pattern — otherwise, it is recommended that tint remain at its default setting. CHROMA LUMA DELAY: This control affects any incoming composite or S‐video signal, delaying the luma signal (intensity) in relation to the chroma (color). In the image, increasing the luma delay will move luma (seen as a shadow where colors overlap) to the right slightly, with colors remaining in place. Decreasing this delay will move the shadow slightly to the left. If necessary for your current source, adjust so that no shadows occur with adjacent colors. Input Levels — SUBMENU NOTES: 1) Because the projector automatically optimizes input levels for all but the most unusual of sources, it is recommended that only experienced users use the Input Levels submenu. 2) Before beginning, check that overall contrast and brightness settings are near 50 and that color temperature is properly set up on an internal grayscale test pattern. 3) There must be at least 2 consecutive white pixels present in the image for proper “Auto Input Level” function. Leave this control off after use. Good RGB or input levels — that is, the drives and black levels for each of the three colors, red, green and blue — insure that images from analog sources other than decoded video have maximum contrast without crushing black or white. By default (and in a “Quick Setup”), the projector automatically determines the best input levels by monitoring image content and adjusting the controls appropriately — further adjustment is typically not required to obtain proper blacks or whites. NOTE: This automatic adjustment requires at least 6‐12 consecutive white pixels in the image. Without these pixels, input levels may produce skewed colors, particularly in non video images. However, for a very unusual source exhibiting one or more overly high black levels (typically caused by a noisy source causing black level spikes), an experienced user may prefer to use the Input Levels menu (shown above). These adjustments, which together serve as a calibration process compensating for differences in sources and cabling, enable an experienced user to perfect the source image input levels and eliminate the “overshoot” and “undershoot”. Note that Input Levels are of limited use with digital signals, but do offer some ability to tweak poorly mastered source materials.
