Motherboard issue, wouldn't boot into OSX and hung at the Apple logo before login screen. However, booting it in target disc mode works fine. I'm assuming therefore that the monitor is still useable. Thus I was wondering of I could use it as an external monitor for a gaming PC I am buying. Don't worry; I replaced that Mac with an i7 27 inch iMac; that's still my primary beast. The PC is just for gaming. The plan is to use a HDMI to MiniDisplayPort adapter. I take HDMI from my PC GPU, then run the DisplayPort end into the iMac. Would that work? I know it needs to use MiniDisplayPort, but obviously the PC doesn't output that, so would that adapter work? Thank you kindly, Adam EDIT: Hmmm, it seems I have made a mistake. To work, the iMac must run into target display mode, but it's only post-2011 models that can do that, not the old ones. Am I fighting a losing battle here?
