Check that the PC is turned ON
Check that the signal cable is properly connected to the
graphics board or PC.
Check that the graphics board is correctly inserted in the
PC.
Use the graphics board’s utility software to change the
frequency setting. (Refer to the manual for the graphics
board.)
For Windows 95 users (OSR 2.0 or newer) or Windows 98,
restart the PC in a safe mode and change the frequency in
the “Display” setting for the PC.
Make adjustments to the “Image”, “Clock” setting in the
