I currently have an iMac (Early 2009, 24 inch), and I'm about to buy a PS3... However, I was wondering if I could hook up the PS3 to my iMac. However, after doing some research, it appears that the PS3 resolution will be scaled down or not even work... So, I was wondering if I bought an external moniter (At this link), could I connect the PS3 to it? Also, If I also wanted to use it for a second display for my iMac, would I have to disconnect the PS3 and reconnect my iMac, and visa versa, or could I just turn off the PS3?
