Compaq 1501 manual Unknown Video Modes

Unknown Video Modes

Like all other monitors, your LCD monitor is designed to work with standard video modes. However, not all video/graphics cards use only standard display modes.

Your LCD monitor uses state-of-the-art technology, which is designed to automatically synchronize to any display mode listed in the above table. We recommend you choose one of the supported modes listed above. If you choose an unknown mode, you will need to manually adjust the clock, phase, and image position and may still get a bad display.

If you must use a display mode beyond the above list, you should run Auto Configuration first. If Auto Configuration doesn’t provide adequate image adjustment, then you must manually adjust the clock, phase, horizontal position, and vertical position. If this still not work, please choose a recommended mode.
