You do get what you pay for in this world. The Highway unit shows almost none of that vertical banding - at 7x the price :-). SteveIt would seem that it should be showing more *even* banding, rather than nobanding...isn't it supposed to be alternating stripes?Actually, my converter does show the banding. Must have remembered incorrectly :-).They are even, though. That desktop shows no banding at all on the original IIGS RGB monitor.
Whether the banding is regular or irregular will depend entirely on the board's resampling clock, and any dynamic adjustments its phase lock loop attempts during a line interval. A *very* high resampling clock (relative to 16MHz) would result in almost no banding, but anything under 32MHz will show significant banding. -michael NadaNet 3.1 for Apple II parallel computing!
