I have just bought a new power mac. after being a pc user for 20 years. My Mac pro as a 1900XT graphics card in it. I run 2 monitors on it. my question is can any one tell me how to get my desktop to span across the 2 monitors. For eg my pc montiors are set at 1680x1050 with both side by side it gives me a desktop of 3360x1050. I can put a background picture on my desktop which spans both monitor. But on this mac I can only show two diffrent pictures or the same picture twice. I want to use one picture and span it across both monitor. Can I do this and if so how? or have i found something a mac can't do that a pc can.
