Display Modes
If the signal from the system equals the standard signal mode, the screen is adjusted automatically.
If the signal from the system does not equal the standard signal mode, adjust the mode with reference to the Video card user guide, as the screen may not display or only the power LED may be on.
For the display modes listed below, the screen image has been optimised during manufacture.
