All, I've run into something interesting. I am using a PanaSync C1381i with CBM's A2320 display adapter. In the deinterlaced 640 by 400 (actually overscanned to 740+ by 420+ but the same happens even in non-overscanned) mode, I have a problem on the right edge of my screen. It seems that I have a zipper for the right edge and it is running up the screen at some harmonic of 60 Hz, I would guess around 15 Hz, or less. I have tried correcting it with the coarse (open loop) and fine (closed loop) adjustents with no luck. Any ideas out there? Thanks in advance. Brian ->on AutoPilot
