I have a beige PowerMac G3 Minitower running OS 9.2.1. Recently the old CRT I had it hooked up to started to die, so I bought a new Samsung 245BW 24" widescreen LCD monitor. The OS doesn't offer the correct resolution (1920 x 1200 @ 60 HZ) so the display is stretched horizontally and after a minute or so the monitor goes dark and displays a warning message about the wrong resolution. As best I remember there is no third party video card in there. What can I do to be able to use this monitor with this computer?
