Ok first it would only start up in verbose mode. So I downloaded Onyx and fix that problem. Then while messing with resolutions to hook it up to my TV I set it to one that it's out of range. So ok I reboot hold down shift key to try "Safe Mode" and nothing just goes right past the Apple logo and out of range again. I tried Cmd+Opt+P+R nothing, tried Option nothing, tried holding down both shift keys and nothing. It will not respond to any post keyboard commands at all nothing. Any other suggestions? And no it's not the keyboard because it works perfectly fine on my iMac.
