ARZ0 is the same as DHR – up to 16 color register changes per high res line. ARZ1 is slightly different in that color register 0 (the background color) is clamped to black. Therefore, you get at most 15 color changes per line and a non-weird border area if the picture is NOT overscanned. As for your question about overscan HAM – I think I CAN give you an explanation. SuperView does not handle severly overscanned HAM images correctly in that it over optimistically offsets such images too far to the left of the screen. In doing so, some pixels on the left side get left off the display's HAM computation causing awful HAM fringes on the left side. You can confirm this is the case by using the SuperView option which disables overscan. If the “break up'' goes away…then this was your problem.
