I just got a great deal on PS3 but don't have HDTV yet. Thinking about getting one though. But at the mean time, is there any way to connect my PS3 to my 24inch iMac and use its LCD screen? A HDMI--->DVI cable?
Don't think the iMac has built in video in, your best bet would be something like a tv capture device, but if you intend on getting a tv later on it's probably not worth it.
