Display Modes
If the signal from the system equals to the standard signal mode, the screen is adjusted auto-
matically. If the signal from the system doesn't equal to the standard signal mode, adjust the
mode with referring to the Videocard user guide because the screen might not display or only
the power LED might be on. For the display modes listed below, the screen image has been
optimized during manufacture.
