Seem to remember reading the Amiga folks have the same issue.
Could well be, there was a couple of commodore monitors that would hitch up to the GS, they're also like hen's teeth now. So there must've commodore/amiga's that had the same style output. SCART LCD's is a small time frame but at least its more recent. And from the GS experience a lot better than trying to convert it into 1080p.
