(When you do so, the ServLINK will also autodetect Brightness, Contrast, and

If the Host PC's screen has vertical bands of flickering or jumps from left to right, the
Modulus setting needs to be changed first. Depending on the colors being

This problem is clearly visible on screens containing a lot of gray, particularly the
Windows 50% gray screen that appears whenever the Windows Shut Down option
is selected from the Windows Start-button menu. To correct this problem and
