The projector will respond to IR remotes set either at the same address as the projector or to IR remotes set to address 0. Image Blending Adjust blend widths and settings to left, right, top and/or bottom sides to create a seamless multi-projector stitched image. (Available only when optional Dual Processor Warp Module is installed.) What 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 below). How are Blends used? In multiple-projector wall, complem entary blends between neighboring images can compensate for the extra brightne ss or intensity where these edges overlap. By controlling blend width an d other properties, you can achieve uniformity across the group of images. Visible overlaps will disappear, as shown below Blending regions can be defined on all sides - left, right, top and bottom. The same gamma curve is used for all blending regions.

Section 4: OPERATION GS Series User Manual020-000724-01 Rev. 1 (05-2014)4-13 Color Matching You may require a unique color gamut (range) for a single projector or application, or you may need to precisely match colors across multiple adjacent displays. Use Color Matching by Meter Adjustment or by Manual Adjustment to define the precise hue of each primary color component (red, green, blue and white). The x/y coordinates for each color define its location on the standard CIE chromaticity graph. Changing either or both of these numbers will change the hue of the color, and modify the range of possible colors. For example, changing the x/y coordinates for red may move the color closer to orange or closer to violet, which will in turn affect all displayed colors having a red component. Adjust the slide bars or enter new specific coordinates as desired to define or change the color gamuts needed for your environment and applications. Enable the selected method (Meter or Manual Adjustment)- this will automatically disable the other method. For both methods, if Auto Test Pattern is enabled, the solid colored test pattern will be displayed according to the menu item on which you are positioned. • Meter Adjustment 1 Using a color meter, enter the current x and y co-ordinates of Red, Green, Blue and White for the projec tor image into the Measured Data menu. This is the reference point for the projector. The default values in the menu are based on the average for all projectors. 2 After measuring the values for all the projectors to be matched, calculate the target values. 3 Enter the target values for x, y and gain for each color into the Target Data menu.

Section 4: OPERATION GS Series User Manual020-000724-01 Rev. 1 (05-2014)4-14 • Manual Adjustment1 Adjust color slide bars and judge image color by eye or meter. A user-defined color adjustment can be applied. 2 Use this submenu if you do not have specific color coordinates in mind and will judge color performance by eye or meter. As for Meter Adjustment, each color control actually defines new x/y coordinates for that color and changes its hue. The main colors (red part of red, green part of green and blue part of blue ) adjust the intensity of that color component, while the modifying colors (e.g. green part of red and blue part of red) modify the x and y value and change the hue of that color. At the same time the main colors also are used to control the color of the white point. Hot-Key Settings Assign a different function to the hot-key on the remote control by highlighting the function in the list and pressing ENTE R. Choose a function that does not already have a dedicated button, and assign the hot-key to that function, allowing you to quickly and easily use the chosen function. Service • Projector Info: Display current projector settings (read-only). • Factory Reset: Restore a ll settings to their default value. It will not reset network but it will reset RS232. • Test Pattern: Choose the desired internal test pattern to display, or select OFF to turn off a test pattern. • Phosphor Index: The Phosphor index synchronizes the phosphor wheel with the filter wheel and DMD. The index defines the delay between the wheel and the DMD. When the Phosphor index is adjusted, it will impact the smoothness and contouring of the R/G/B gray level. • Filter Index: The Filter index synchro nizes the filter wheel with the phosphor wheel and DMD. The index defines the delay between the wheel and the DMD. When the filter inde x is adjusted, it will impact the smoothness of the white color space without contouring, similar to the phosphor index behavior. • Error log: Show the projector error log for debug. • Mode Adjustment: Fine tune the H and V start position for a signal in the EDID timing table and record the values in the system to override the timing table. The settings must be Saved to Record before exiting the menu, or they will be lost. To revert to original timing table settings, each setting must be manually cleared. Factory Defaults wil l not clear these override settings. • Laser Diode Info: Display current laser banks status and temperature information. • High ambient temperature warning: Show the warning message the when the ambient temperature is over 35°C.
Section 4: OPERATION GS Series User Manual020-000724-01 Rev. 1 (05-2014)4-15 4.4 Light Source Light Source Mode Select Constant Power, Constant Intensity or ECO mode. When in ECO mode, the projector will adjust to the lowest fan speed and switch the laser diode power to the mi nimum setting. Constant Power Set the value of the laser diode power (in Watts). Constant Intensity Set the value for the Constant Intens ity to maintain constant brightness. The light sensor will monitor the light level and will apply more power as the laser brightness decays naturally over time. When the laser setting reaches maximum power of 405W, it will remain at this setting. Note that the light sensor needs to be calibrated for Constant Intensity mode to work properly. Calibration should be performed again after every lamp change. Total Projector Hours Display current total hours the projector used. Light Sensor Calibrate light sensor.
