[. . . ] · For fixed-pixel devices, use RGBHV from the Lumagen to drive BNC inputs, when available, to minimize noise. For RGB, "Luma noise" is distributed across the red, green and blue channels but for component, Luma noise is all on the Y (Luma) channel. So, RGB sources can show lower noise levels since the weighting of the three channels for "Luma" as perceived by the viewer tends to filter out some of the Luma noise. · Contrary to popular opinion, most fixed-pixel displays look best running their input at a resolution higher than their native resolution, such as 1024p, and in some cases 1080i, for a 720p or 768p display. This is because the process of "down-sampling" the higher resolution to the display's native resolution can filter out some of the noise and provide more detail. Note: Rules for display of Video are completely different than for the display of PC data. For display of PC generated data, such as spreadsheets, the PC resolution should be set to match the native resolution of the display. · Avoid running video signals through the video switch inside receivers, as these tend to degrade video quality. The rule of thumb for a video switch is to have 10 times the bandwidth of the video being switched. · Component inputs on some RPTVs and projectors do not work with standard width HSync pulses. When using component video to drive the display, if there is a "green cast" the likely cause is a design problem in the circuitry inside the display. Changing to bilevel sync, and/or making the HSync pulse narrower with the Lumagen HSync Width command (MENU 0 9 4 0) can help eliminate this problem. · A system's "ground loop noise" can cause problems. Since the Lumagen case "floats" it may need to be grounded to the video source and/or display. · Component DVD sources provide the best standard-definition picture quality, but SVideo sources are often a bigger challenge and therefore can show more improvement using Lumagen. Since many satellite receivers, and other video sources, only have composite and SVideo outputs, this improved SVideo performance is important for many installations. · Memory A (MEMA) and memory B (MEMB) can be used to have two independent configurations, such as for day (bright room) and night (dark room). One difference for this example is that the black level will be set higher for daylight viewing than for viewing in a darkened room. To program MEMB to be different, first setup MEMA normally, use the input copy command to copy to MEMB, than adjust MEMB as desired. Remember to save changes. © 2003 Lumagen, Inc. 13 Rev 1. 13 Vision ProTM User Manual and Installer Guide Command Format VisionPro commands are selected with the supplied infrared remote, or the RS232 serial port. To prevent possible command conflict, only one of these inputs should be used at a time. The infrared remote control command notation is described below: · Remote buttons are named as shown on the remote in a bold font. [. . . ] If there is still no picture, press MENU, 0, 9, 9, 9 on the remote to reset parameters to factory defaults. After the monitor warms up, press the MENU button on the remote control. If the inputs work properly, the problem is with the display, display cabling, or output setup. If these steps fail to resolve the problem, contact a home theater specialist for additional assistance. [. . . ]
