4 On your external test pattern source, select a PLUGE pattern. (PLUGE is\ an acronym for “Picture Line-Up Generation Equipment.”) Figure 4-9 shows a typical PLUGE pattern. PLUGE patterns vary but generally consist of some combination of black, \ white and gray areas against a black background. The example above includes two vertical bars and four shaded\ boxes. Below Black Above Black Figure 4-9: Typical PLUGE Pattern for Adjusting Brightness Brightness: Select Brightness from the Image menu....

4 Contrast: On your external test pattern source, select a stepped, gray-bar patter\ n like the one shown in Figure 4-10. Figure 4-10: Typical Gray Bar Pattern for Adjusting Contrast Select Contrast from the IMAGE menu. Use the or buttons to adjust the contrast up until the top two bars be- come almost the same brightness, then down just until the brightness cha\ nge between these bars is consistent with the other bars. NoteBrightness and Contrast controls are interactive. A change to one may...

Figure 4-12: Typical Test Pattern for Adjusting Sharpness Sharpness (Simple Mode): Adjust as needed, looking for white edges aro\ und the transitions from black to gray and differently-sized lines in the “sweep” patterns at the top and\ bottom. Lower the sharpness setting to elimi- nate them. Sharpness Mode: Sharpness Mode allows or...

45 Noise Reduction: To apply noise reduction to the source signal, select Noise Reduction fr\ om the IMAGE menu and press ENTER. Figure 4-13: Noise Reduction Sub-Menu Noise Reduction is useful for clearing up noisy images from interlaced S\ D sources. Noise Reduction (Simple Mode): Use the or buttons to adjust as desired, keeping in mind that reducing noise (which reduces high frequencies) may also soften the image. Noise Reduction Mode: Noise Reduction Mode allows or prevents access to \ the...

Figure 4-16: H9080FD ADVANCED Menu Color Space: Select Color Space from the ADVANCED menu to choose the color space of t\ he source signal for HDMI, RGB, and component connections. The default setting, Auto, functions as follows: HDMI: If the Auxiliary Video Information (AVI) infoframe contains colo\ r space and/or range data, the H9080FD uses that information. Otherwise, for RGB...

4 Video Standard: Select Video Standard from the ADVANCED menu to specify the color system\ for composite video or S-Video input signals. Different countries use different formats for video signals. Select the \ appropriate Video Standard for your region: Auto: The color systems are automatically identified and the format is s\ et accordingly. NTSC: This is the standard format used mainly in the United States and J\ apan. PAL: This is the standard used in Europe, Australia and many other...

50 RGB Adjust: To remove any trace of color from the white areas of the projected image\ , choose RGB Adjust from the ADVANCED menu and press ENTER. This displays the RGB Adjust sub-menu\ , shown in Figure 4-17. Figure 4-17: RGB Adjust Sub-Menu Offset: Use the Offset controls in the RGB Adjust sub-menu to correct co\ lor imbalances in the dark areas of the image. A good way to do this is to use a test pattern consisting mos\ tly of dark gray areas, such as a 30 IRE “window” pattern. If the gray...
