I have a G4 Quicksilver 2002, OS9.2.2, 1gig of RAM, with an Nvidia GeForce2 video card and 64mb of VRAM.
I currently have a 17" Sony that is older than my high-school son, and works perfectly. It's just...small. I'd like to get a larger monitor. I've tried a couple of larger-format monitors (both Acers), and the same thing happened both times: in OS9, the only resolution I could choose was 640x480; and in OSX Leopard, the screen just went black after booting up.
I was told by the seller that this particular card will support up to 1920px wide resolutions. So far, it only supports a single monitor, and no higher than 1280.
Does anyone have any insight into what might be going on?
