I recently threw out my space consuming CRT monitors and bought two new Samsung S19B 150N LED monitors, connected them, and nothing. The monitors each work with another computer and the G5 shows up on a different monitor, so everything is working separately but not together. Any suggestions please???? Somebody suggested that maybe the monitors are too new for the graphics card. If so, what card should I go for to run the two monitors. I'm just an ageing video editor. I don't do gaming. It is a pretty old dual core G5 running an early OSX.
