The problem today is, Interlaced video is not handled as higher resolution non interlaced output, so the picture jumps and looks bad, is it possible to handle this ? So the amiga thinks it output Interlaced video, but we see a nice steady picture ? The raspberry PI handle full HD resolution, so i think it should be possible ?
Deluxe Paint 5 in Workbench is a perfect test tool for higher screen resolutions, as it is now we see lockups or guru meditations if any higher resolutions are selected.
