I've Googled, Wikipedia'ed, and MRoogled about this, but I haven't been able to find any useful information. I have a CD Mac mini, which of course has DVI out. I recently (Friday) bought an RCA HDTV and connected the two using a Belkin (sigh) HDMI <-> DVI cable. The display worked fine, aside from the annoying "Either two inches of black space around the image or overscan" dilemma because of the 1366x768 (or w/e) resolution. The bigger problem, though, was that whenever I powered off the screen, the Mac mini would crash. It would become completely unresponsive to network connections and any audio playing at the time would stutter until I powered the machine off. It would not respond to any other input, whatever the source. I switched to a VGA connection, which has visibly less brilliant colors but fixes the image size problem and the annoying crashing problem. I still don't understand the crashing problem, though, since I thought that DVI only carried display information, nothing likely to crash the Mac mini. Sorry if this is answered somewhere else or is painfully obvious. I've never heard or read about this, so I find it kinda puzzling.
