Hey, I realize this thread is almost a year old, but I do have info on this monitor. I own a 21" SuperScan Supreme 803, model number CM803U. I don't know how it differs from the Elite, but it's a very nice monitor considering. It's a shadowmask monitor with a small dotpitch. I believe it maxes out above 1600x1200 at over 85Hz. I run mine at 1280x960@85Hz. It's not a flat screen, though not too round. It is ;hysically pretty large, though.
They were extremely nice monitors for the time, and I'm still quite pleased with mine, it's a very sharp picture. To put that time in perspective, though, mine was made in Sept 1997. I believe later ones had DVI connectors, but mine does not.
