When “Auto Sync” is set to OFF or when vertical stripes or flickering occur in portions of the screen even if “Auto Sync” is set to ON, adjust “Clock”, “Phase”, “H-Pos” or “V-Pos” to obtain the best com- puter image.

Ordinarily, the type of input signal is detected and the correct resolution mode is automatically selected. However, for some signals, the optimal resolution mode in “Special Modes” on the “Fine Sync” menu may need to be selected to match the computer dis- play mode.
