both an Nvidia card and onboard video. So I dig out an analog cable
and try the onboard video. No difference. I power-cycle the
monitor. No difference, except it's getting increasingly messed up.

"So I think maybe I'm looking at a dying monitor. That would be
very sad, because it's a nice Viewsonic 22" LCD and it's only a

partly sad. But I'm getting ahead of myself, because I haven't
tried it on a different PC yet."
