I tried searching mroogle for awhile but I could not find the answers I needed. I apologize if this is a repeat question. My situation is I have a 2008 Mac Pro desktop, a PC gaming machine, and a 30" ACD. My goal is to hook both machines up the one monitor and then be able to switch from one computer to the other. Yes, I have bootcamp, yes I have vmware, no I don't like running windows on my mac! Plus, the PC is for gaming, like I said, and my mac is work only. I really don't feel like shelling out $350 for a decent mac video card when I can buy the same one for under $100 on the PC. My question is can this be possible? My first thought is the ACD has too few input options. That being said, does anyone know if this would be much easier with a Dell 30"? I'm not opposed to selling the ACD and buying a Dell monitor. Any info is much appreciated.
