61 it is sometimes difficult to observe artifacts such as external de‐interlacing/resizing and signal noise. Remove the checkmark to return back to normal. Color Enable Select which color or colors you want to see. This is useful while working with color temperature, input levels or other special setup parameters. Colors can also be enabled/disabled by entering the corresponding function code listed on the back of the standard remote keypad. Odd Pixel Adjustment NOTES: 1) Factory‐set and rarely required by user. 2) Source must be >90 MHz. When using certain RGB sources, you may need to adjust the normal gain or offset of odd pixels in relation to even pixels. This will smooth out very narrow (one‐pixel wide) “checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Using the Level Detector simplifies this process: 1. Use an external analog native‐sized continuous grayscale test pattern with at least 256‐levels. 2. Turn “Level Detector” on. 3. Set “Level Value” to ~200. The image should now be black‐and‐white (or black‐and‐one color, if you use “Color Enable” function). 4. Adjust offset. Half of the pixels will move, the other half will not. 5. Adjust until the two transition regions overlap. The stripe of noise will be minimized, defined by the value in the slide bar. 6. Set “Level Value” to ~800. The image should now be black‐and‐white. 7. Repeat Steps 4 and 5, but adjusting gain. 8. Repeat Steps 3‐7 for all remaining colors. Your RGB source should now be OK. Two sets of values are automatically saved with these controls — one value for Input #1, and one for Input #2 (analog). The current set of values depends on which source is in use. This enables a source to be processed correctly via two different inputs. NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates “one pixel on, one pixel off” artifact only, not any type of larger artifacts. Peak Detector The “Peak Detector” is a fast method for defining individual input levels, and can improve the accuracy of input levels set by the Auto Input Level function. Enabling the “Peak Detector” activates a special operating mode for detecting only pixels that are considered black or white — all other levels are displayed as a mid‐level gray. When used with a 16‐step grayscale pattern in which the two black and white bands are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual black levels and white levels until both
62 bands are just visible. Images from this source will then display correct blacks and whites without crushing or washing out. NOTE: If using Peak Detector with PIP, both images must have the same color space. Level Detector The “Level Detector” checkbox enables specific thresholds for blacks and whites — input levels that fall below a specified Level Value (see below) are displayed as black, and all others are displayed as white. It aids in Odd Pixel Adjustment. To use: 1. Enable “Level Detector” and display a continuous grayscale. 2. Set “Level Value” to near black (such as 200). 3. Adjust Offsets to minimize area of black stripe. 4. Set “Level Value” to near white (such as 800). 5. Adjust Gains to minimize area of white stripe. Level Value Level Value defines the value to be used by the Level Detector in recognizing blacks and whites. See Level Detector, above. Aspect Ratio Overlay Selecting this option with a checkmark will overlay a number of common aspect ratio boxes on top of the source image. This is very helpful during the setup of the projector and can be turned off after desired specifications have been achieved. Lamp Tracking Calibration NOTES: 1) Lamp Tracking Calibration takes up to two minutes. 2) For best results, allow the projector to warm up for 15 minutes prior to calibration. Lamp Tracking Calibration defines the range of power needed to maintain lamp brightness. Select Calibrate Lamp Tracking for calibration using your projector’s unique specifications (recommended) rather than standard specifications. The projector will revert to the default backup in the event of a power failure. Lens VariScope System (LVS™) Calibration This option allows you to choose between three types of lens calibrations. Reference calibration determines a reference point that is used as a defined starting position for relative motion of the lens. All positioning is measured from this reference point. A reference calibration is lost when power is removed from the projector and will occur on every power up as long as LVS™ is enabled. A Motion calibration determines the characteristics of each motor and values are saved in the projector’s memory. If LVS™ is enabled and a motion calibration has previously been done, the projector will automatically recall these settings from memory when it’s being powered up and a motion calibration will not take place. A Full calibration performs both a reference and motion calibration.
63 Automatic LVS Lens Calibration NOTE: It is recommended to leave this feature disabled. When this option is selected (default) and the projector is in LVS mode, the projector will perform a lens calibration on each power‐up. During calibration, the shutter will be closed and the status LED will display ‘LC’. If LVS is not selected, the ALC setting will be ignored. If, during power‐up, ALC is not selected and LVS is, the last stored location from the previous LVS calibration will be assumed to be true and the lens will moved to that position upon power‐up if necessary. Picture In Picture [PIP] NOTE: To control the primary image, access all picture controls through the Main menu. To control the secondary (PIP) image, access picture controls through the Picture‐in‐Picture or Switching menu. Use the first of six options in the PIP menu to enable and define how you want to use PIP. Swap Main and PIP Image Toggle the current picture‐in‐picture relationship so that the primary (main) image becomes secondary (PIP), and the secondary image becomes primary. Swapping is available only when PIP is enabled. NOTE: There may be a slight delay when swapping the Primary and Secondary images. PIP Enable Short cut: Press PIP on the Remote if menu not present. Toggle to display from two sources at once (Picture‐in‐Picture) or the primary source only. This checkbox turns the secondary source on and off. NOTE: Disable PIP and Best Switching for Interlaced sources > 35kHz. PIP Size and Position Most controls in the PIP Size and Position menu adjust the PIP (secondary) image in the same fashion as their counterparts in the main Geometry and Position menu adjust the main image — see Adjusting the Image for details. Exceptions are: POSITION PRESETS – Set the location of the PIP (secondary) image in the display. ASPECT RATIO PRESETS – Choose the desired aspect ratio for your PIP pixels. Use the “Default” aspect ratio when incoming format has square pixels (most common). This insures that the
64 resulting PIP image maintains its intended aspect ratio. Use “Anamorphic” for NTSC signals having narrower pixels‐‐this will stretch the pixels horizontally to regain the intended aspect ratio of the PIP image. NOTE: If the image is already resized at the source it will remain that way in the PIP window. If, for example, an NTSC signal is already set to anamorphic through the Resize and Preset menu it will remain that way in the PIP window. If the NTSC signal is formatted as widescreen at the source, then the image in the PIP window will appear with black bars above and below it. PIP Image Settings Adjust the PIP (secondary image) without affecting the size or position. The primary image remains unchanged. See Adjusting the Image, for details PIP Border Width Set the desired line thickness for your PIP window border. PIP Border Color Select the desired color for the PIP window border. NOTES: 1) Numbers 7 and 8 on the Picture‐in‐Picture and Switching submenu control switching parameters. 2) Disable PIP in order to work with Seamless Switching. 3) Disable PIP and Best Switching for Interlaced sources > 35kHz. Working with Seamless Switching Seamless Switching is the ability to instantly and/or smoothly switch sources, and is controlled with options 7 and 8 in the PIP menu. To use Seamless Switching, PIP must be disabled. Tips for best source switching: • Insure a channel has been configured for each source. • Progressive digital and analog sources are recommended. • Set Image Optimization to Seamless Switching (see below). • For best results, use the same frame rate and gamma setting for each. NOTE: Avoid using two interlaced sources. Image Optimization Use this setting to choose what is more important, image quality or switching between sources. Selecting Best Image Quality will insure your image is always proper however when switching sources, the screen will go blank increasing your switching time. Smooth Switching allows for a cleaner transition between sources. The image will fade from one image to another according to the Fade Time control. Seamless Switching overrides the Frame Lock Enable settings and forces the output to run at 60Hz regardless of the input signal. Image is 100% seamless when switching sources. NOTE: Disable PIP and Best Switching for Interlaced sources > 35kHz.
65 Fade Time Set how long (in seconds) it takes to gradually dissolve one image into another for a source switch when Image Optimization is set to Smooth Switching. NOTE: PIP must be disabled for Fade Time to take effect. Also, the PIP window must be closed to activate it. Numbers Select Main Image Use Numbers Select Main Image to use the numeric keys #1‐8 as input keys. This remapping of the keypad (see right) can be particularly useful with PIP displays, providing a convenient shortcut for changing the primary (background) image without first having to return to the Main menu. Select “Always” to use the keys in this manner all of the time, even with single displays. For normal keypad function, select Never (default). Set to When PIP Active to activate number keys only when PIP is in use. NOTE: Numbers Select Main Image keypad functionality works only when menus are closed. The Cermax® Xenon Lamp Whenever you install a new lamp in the projector, access the Lamp menu to record the lamp serial number in the projector’s memory. You can also choose a lamp mode for regulating power and light output, change Iris size, and access other read only information pertaining to past and present lamps. LAMP HOURS (read‐only) shows the number of hours logged on the current lamp. Whenever you record a new lamp serial number this value automatically resets to “0”, where it begins to log time for the new lamp. This information also appears in the Information menu. LAMP S/N (read‐only) is the serial number recorded for the current lamp. When you install a new lamp and enter its serial number, the number will appear here. Enter a checkmark for LAMP MESSAGE to enable a warning message that will appear upon power‐up when the lamp has reached the specified lamp limit and should be replaced. Delete the checkmark to prevent display of this message — instead, when your lamp expires, only the status display messages on the back of the projector will provide the visual warning to replace the lamp. NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) When a lamp warning message appears, press Exit to temporarily cancel the message. The message will continue to appear upon power‐up until you install a new lamp. Set LAMP LIMIT to the number of hours you expect to log on the current lamp before replacing it. This will trigger a lamp message on‐screen (if enabled). NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally expected may no longer be possible. 2) Turning the lamp on and off reduces lamp life significantly, as do
66 other factors. 3) It is recommended that Lamp Limit not exceed the expected lamp life, otherwise a lamp could become dangerously fragile with overuse. Set which LAMP MODE you want to use in order to control the light output. You can choose to run the lamp as bright as possible (i.e., always using maximum power — this is the default upon power up) or you can power the lamp with a specific wattage appropriate for the installed lamp or you can set a specific intensity (brightness) to maintain. Although there are exceptions, generally higher light output or higher power settings can shorten lamp life. Use the lamp mode that best suits your brightness needs. For example, in a tiled application you may want to precisely match brightness levels between adjacent images — judge by eye and set each individual Lamp Power setting as necessary. Or if you want images to be as bright as possible — choose Max Brightness. Always keep in mind that higher lamp power settings can shorten lamp life. Lamp modes are described below: • Max Brightness: The lamp will always burn as brightly as possible, driven by 100% of the power level rating for the installed lamp (see Section 6, Specifications). Keep in mind that the “maximum brightness” for any lamp gradually diminishes with age — images will become dimmer over time. Its current output level appears in the “Intensity” option (not in lumens). • Intensity: Brightness will remain close to a specified level for as long as possible. Once you select this option, enter a number representing the intensity level (brightness) you wish to maintain — the projector will automatically adjust power as needed to maintain this intensity as closely as possible. Note that the intensity value is a correlation only and does not represent an actual lumens level. See “Intensity” below. • Power: The power supplied to the lamp will remain at your specified wattage level. Once you select this option, enter the number of watts representing the power level you wish to maintain. See “Power” below. POWER – This slidebar and number indicates how many watts are applied to the lamp. You can apply anywhere from approximately 60‐65% of the maximum power intended for the installed lamp up to 100% of the lamp rating. Set for the number of watts as desired, keeping in mind that lower power levels produce dimmer images. When in either Power or Max Brightness modes, the power level remains constant. Specifying a maximum power level here is the same as operating in Max Brightness mode. NOTE: Power level can be set only if the lamp is in Power mode. INTENSITY – This value and slidebar represents the current brightness of your lamp, decreasing over time when you are operating in Max Brightness mode or at a specific Power level. When you are operating in “Intensity” mode this value remains at the original “Intensity” setting chosen and cannot be adjusted. NOTE: The number shown for “intensity” is not the actual lumen output, but rather a correlated value only — 1246 may represent 3500 lumens, for example. To use “Intensity” mode, judge by eye (or use a meter) and set the level as desired for your application. Over time, the projector will automatically increase the power supplied to the lamp as needed to maintain the chosen intensity as closely as possible.
67 HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain your “Intensity” setting until the required power reaches the maximum rating for the lamp. The lower the setting, the longer it will take to reach this threshold and the longer you can maintain the desired brightness. Keep in mind that once the lamp power reaches its maximum wattage (see “Power”, above), this tracking is no longer possible. At this point, the lamp will gradually begin to dim as usual, even though your original “Intensity” value will still appear in the menu. To resume accurate tracking, reduce the intensity setting so that the resulting “Power” value is less than its maximum — the lower the intensity, the longer it can be maintained. For example, a 1000 watt lamp can be driven at no more than 1000 watts. To produce desired brightness at the screen, a new lamp would likely need less than this maximum rating—perhaps 812 watts (example only). Over time, however, the lamp will require more and more current in order to generate the desired light, until eventually the lamp wattage reaches its 1000‐watt maximum and the lamp power automatically levels off. At this point, the tracking function terminates (i.e., the power level stabilizes) and the lamp will begin to dim normally. Either reduce your “Intensity” setting or replace the lamp. Do not lower the “Intensity” so much that the corresponding “Power” value reaches its minimum — the intensity setting will be inaccurate and cannot be maintained. For best results in achieving uniform intensity amongst tiled images, choose an “Intensity” setting that enables all lamps to operate at less than the maximum number of watts available in your projector but high enough to keep the corresponding lamp power above its minimum. See “Power”, above. NOTES: 1) Lamps become more stable over time, thus a specific intensity is more easily maintained as the lamp ages. 2) Intensity can be set only if the lamp is in “Intensity” mode 3) Intensity cannot exceed the output of Max Brightness mode. IRIS – The IRIS inside the projector controls the diameter of the light beam passing through the system. With a fully open aperture (slidebar default of “0”), the maximum amount of light passes through for maximum brightness in your images. Increase the slidebar setting to reduce the aperture diameter and maximize contrast ratio instead. LAMP HISTORY – This read‐only option lists the lamps most recently installed and recorded in the projector. Lamp History automatically updates whenever you record a new lamp serial number — the new lamp is added to the bottom of the list. Use CHANGE LAMP to record the serial number for a newly installed lamp: In the Lamp S/N window, use the number text entry keys to record the new lamp serial number and press again to accept the change. See Using Slidebars and Other Controls if you need help entering the number. Once entered, the new lamp serial number will be added to the Lamp History menu and the Lamp Hours timer will reset to “0”. Lamp Mode and Lamp Limit remain as they were for the previous lamp and can be changed at any time.
68 NOTE: Enter a serial number only if you have just installed a new lamp. This will help insure that lamp timer is not reset on an old lamp and that the number of hours logged on the lamp will be accurate. IMPORTANT: Always record the serial number of a NEW lamp. When a new lamp is installed and its serial number recorded by selecting “Change Lamp” in the Lamp menu, the lamp timer resets to “0” and begins logging time for the new lamp. This tally appears in both the Lamp menu (see right) and the Information menu. To review the number of hours logged for previous lamps, consult the Lamp History menu. When to Replace the Lamp If the “Lamp Message” checkbox has been enabled in the Lamp menu (recommended), an expiry message will appear upon power‐up when the lamp has reached its defined “Lamp Limit”. The lamp should be replaced. The “Lamp Limit” setting should not exceed the expected lamp life, as an old lamp becomes increasingly fragile and more prone to sudden failure. The Status and Information Menu The read‐only Information menu lists a variety of details about the standard and optional components currently detected in the projector. Refer to the Information menu for versions of hardware and software installed, the type (size) of lamp, the hours logged in total and for a specific period (such as a rental period), and for your projector model name and serial number. In addition, the Information menu identifies the current channel, its location, its frequencies and other details. Scroll down for additional details. Achieving White Field Uniformity WHAT IS WHITE FIELD UNIFORMITY? • No area of the screen appears more red, green or blue than another • No area of the screen appears brighter than another • Color and light output from one screen closely matches adjacent screens Before You Begin
69 Read through the entire procedure before attempting to adjust White Field Uniformity controls, and keep in mind the following checklist of prerequisites and guidelines: • ADJUST COLORS FIRST — Always adjust the primary colors as described in the “Matching Colors in Multiple Screens” procedure (above) before attempting to work with White Field Uniformity. This insures that primary colors, color temperature, and maximized light output are all well matched from one screen to another. These matches are needed before you can achieve good White Field Uniformity results. • RUN LAMP FOR 100 HOURS— Light output and White Field Uniformity can vary significantly during the first 100 hours of lamp use. For best results with new lamps, either set up White Field Uniformity after this period, or do an initial setup and re‐check at 100 hours • SET LAMP POWER — Insure that each “Lamp Power” setting is as high as possible for your application while still maintaining a good overall match of light output from screen to screen. By nature, achieving a uniform brightness will require a slightly reduced overall brightness—this reduction will help insure that you have enough range of adjustment when examining brightness variables more closely from screen‐to‐screen, and will help prevent premature “maxing out” when trying to match to a certain color, zone or projector. • USE A “USER” COLOR TEMPERATURE — Always adjust White Field Uniformity for a User color temperature defined when you matched primary colors, and continue to use it for all sources displayed on the wall. Your other color temperatures will not necessarily be matched from screen‐to‐screen. • WHITE UNIFORMITY SLIDE BARS — White Uniformity slide bar values may not reduce to “0”. Each slide bar adjusts overall light output in a specific screen zone, but the value shown represents the current setting for green in this zone. When other “hidden” values (red or blue) are lower than green, during adjustment in the White Uniformity menu their values will reach “0” first, causing the slide bar to stop earlier than expected. • JUDGE BY EYE OR USE A METER — Good White Field Uniformity can be achieved with either. Step 1: General Setup 1a) Adjust primary colors (see Matching Colors in Multiple Screens) to insure matched overall color temperatures and light output between screens. IMPORTANT: Double‐check that all WHITES and LIGHT OUTPUT are well‐matched. 1b) Enable the White Field Uniformity checkbox. This will enable access to the uniformity controls and will apply the settings to your image. 1c) Select the 13‐Point test pattern for display. This pattern provides nine screen “zones” with 13 targets.
70 FOR BEST RESULTS: Rather than examining the CENTER of each zone when assessing White Field Uniformity adjustments focus on extreme EDGES as indicated in the illustration at right. 1d) In either Color Adjustments menu, select a “User” color. Then: • If you have created a “User 1” color gamut (recommended) for a well‐matched wall, continue to Step 1e. • If you prefer maximum brightness rather than a particular color temperature, select “Max Drives”. IMPORTANT: Do not change User 1 Color Adjustment in color‐matched applications! 1e) In the White Uniformity menu, set the “Overall” output level to 50.0 and all remaining slide bars to 0.0. This decreases the light output just enough throughout the screen so that any color level can then be increased later as necessary for matching light output from zone‐to‐zone. Do not exceed 50.0 for “Overall”—a higher level will likely interfere with achieving White Field Uniformity and is not recommended. Insure that overall light output remains well matched from one screen center to the next. Where necessary, increase or decrease Lamp Power slightly to recover center matches. Step 2: Adjust Color (level of red/green/blue) in Eight Zones NOTES: 1) At this point, ignore the brightness of individual zones. 2) Always ignore menu colors. 2a) On each screen, compare the color temperatures in the eight target zones (four edges and four corners) to that of the color temperature of the center. Compare using a white field only, and take note of any areas that do not match the center. Also decide if any screen exhibits a more obvious color shift than other screens — begin with this screen in Step 2b. 2b) Return to the White Field Uniformity menu. Beginning with the screen that exhibits the most obvious color shift(s), for each edge that exhibits a noticeably different color temperature from the center, select the corresponding Uniformity adjustment menu — Left, Right, Top or Bottom. For example, if any part of the left side is too blue, too red or too green, go to the Left Uniformity menu and adjust the colors (i.e., change their light output) until all portions of the left side closely match the center color temperature. Adjust an edge first (focusing on its center), and then adjust its corners. Repeat the color adjustment of sides and corners for each edge of the screen that does not yet match the center (note that each corner is adjustable in either of its two adjacent “side” menus). When done, all areas of a given screen should match. Repeat Steps 2a & 2b for all remaining screens.
