3-48 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 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 s\ horten 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. Section 3 ► Operation 1. 2. 3. 4. 5. 6. 7 8.

3-49 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. hoW long Can I MaInT aIn 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. Section 3 ► Operation
3-50 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. See Figu\ re 3.19. Section 3 ► Operation Iris Figure 3.19. Recording the New Lamp Serial Number Iris
3-51 noTe: Enter a serial number only if you have just installed a new lamp. This will help ensure that lamp timer is not reset on an old lamp and that the number of hours logged on the lamp will be accurate. IMPoRT anT: 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. 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 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 the full Information menu using . Use for page up/down.

3-52 Section 3 ► Operation 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 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 ensures 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 — Ensure 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 ensure 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 TeMPeRa TURe — 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. 3.9 achieving White field Uniformity
3-53 Section 3 ► Operation sTeP 1: geneRal seTUP 1a) Adjust primary colors (see Matching Colors in Multiple Screens) to ensure 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. foR besT ResUl Ts: 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”. IMPoRT anT: 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. Ensure 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. 1. 2. 3. 4. 5. 6.Uniformity Enable Test Pattern Left Uniformity Right Uniformity Top Uniformity Bottom Uniformity White Field Uniformity Off 9. 0.

3-54 Section 3 ► Operation 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 scree\ n 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. See Figure 3.21. 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. sTeP 3: aDjUsT lIghT oUTPUT In eIghT zones 3a) For each screen, compare the light output of each edge and corner to that of the center. If any of the areas differ, use the White Uniformity menu to match edges and corners to the center as described below (see Figure 3.22). Begin with the screen exhibiting the most obvious variations in light output. Adjust • edge White Uniformity first—note that each edge adjustment also affects the rest of the screen slightly. Keep all edges just slightly lower than the center light output rather than matching light output precisely. Otherwise, it may not be possible to brighten the corners (typically the dimmest areas of the screen) enough. I.e., the best uniformity is a compromise between the brightest and darkest areas of the screen. Adjust • corner White Uniformity last—each corner adjustment affects only this quadrant. Repeat for each screen. • Figure 3.21. Match Zones to Center Color Temperature

CanCellIng WhITe fIelD UnIfoRMITY If you do not want to use or apply White Field Uniformity settings, delete the checkmark from the “Uniformity Enable” checkbox at the top of the White Field Uniformity menu. Edge Blending is an innovative set of software functions that can quickly and easily blend white levels along the edges of multiple adjacent projected images to create a single seamless larger image. Wha T Is a blenD? In simple terms, a blend appears as a gradient strip along an edge of a projected image. It is darkest along the extreme edge of the image, and lightens nearer to the rest of the image (see right). hoW aRe blenDs UseD? In multiple-projector walls, complementary blends between neighboring images can compensate for the extra “brightness” or intensity where these edges overlap. By controlling blend width and other properties, you can achieve uniformity across the group of images. Visible overlaps will disappear: Figure 3.23. Edge Blending Concept 3.10 edge blending
3-56 Section 3 ► Operation For best results, use the same projector model and type throughout your display wall. In addition, avoid high-gain screens whenever possible—the optical performance of such screens demands minimal image offset, thus projectors must be located very close to one another. Edge blending software controls are located in the two-page Edge Blending submenu—access via Display Setup menu, then go to the Geometry and Color menu and select Edge Blending. The More option opens the second page of the Edge Blending submenu. MaIn fUnCTIons Use Edge Blending controls to set the precise width, shape and midpoint you need to blend overlapping edges together smoothly. blend Width • determines how much area is used for blending along an overlapping edge. Slide bar values represent the number of eight-pixel steps used for the blend. For example, a setting of “eight” creates a blended edge 24 pixels wide. A setting of “0” signifies no blending. For best results in most applications, use a blend width of 16-48 steps (128-384 pixels). Ranges: 0-80 horizontal, 0-60 vertical. blend shape • determines the rate of roll-off across the blend width, i.e. how quickly the white levels across the blend change from light and dark. Increasing the Blend Shape setting accelerates the rate of change at both extremes so that less of the region appears mid-gray (see Figure 3.24). Decreasing the Blend Shape setting slows the rate of change so that more of the region appears mid-gray. For most applications, this subtle control is best left close to 50. blend Midpoint • determines the white level at the blend midpoint (the point equidistant between the beginning and end of the blend). Increasing the Blend Midpoint setting creates a blend that appears brighter than the rest of the image. Decreasing the Blend Midpoint setting creates a blend that is darker than the rest of the image. A setting of 50 means the midpoint is approximately 50% black— for best results in most applications, keep fairly close to this default. Figure 3.25. “Midpoint” Examples Figure 3.24. “Shape” Examples
