I've got a $4.00 "as is" "High Resolution" :lol: AppleColor RGB Monitor that I keep my work shoes on top of . . .

I'm continually amazed that twenty-something year old FixedRez Apple CRTs still work at all! Gotta be vertical or horizontal scan rate adjustment issue, I would think. The cards are more likely to be fine than the Monitor. Somebody that knows how to run a sillyscope could probably explain how the edges of the analog signal wave forms are shifted, rounded or borked in some unspeakable way. Be grateful that the monitor is working at all with any card combo.

My uneducated guess would be that the slop being fed by some of the cards is just catching the edge of the slop the monitor thinks it's supposed to be looking at for synchronization.

Adjust the monitor to eat the slop in the middle of the trough and all the little piggies will happily be makin' bacon! :o)

I should play with mine to see if it's still alive, I chopped the bottom off of it and the top off a 6xxx desktop to mate the two as a TrinitronTVtunerMac, but it was almost as fugly as the real MacTV, so I never even tried to work out the cooling issues.

If I'd known that High Resolution meant 640 x 480 when I found the thing, I would have saved the $4.00! ::)
