Computer Image Menu
NOTE: This menu is only available when a computer is connected.
FREQUENCY—Change the display data clock frequency to match the frequency of your computer graphics card. If you see a vertical flickering bar, use Frequency control to minimize the bars. This is a coarse adjustment.
TRACKING—Synchronize the phase of the display signal with the graphics card. If you experience an unstable or flickering image, use Tracking to correct it. This is a fine adjustment.
NOTE: Adjust Frequency first and then Tracking.
