Right I have the newer unibody mini hooked up to my 50" plasma. All was working well until I turned it on this morning and nothing. Green Light - check, Startup sound - check ..... but no screen image- (just black). I thought it may have been the HDMI cable so I replaced that today, but that didnt fix it. Then I remembered that before I went to bed last night I was playing with the resolution settings and was surprised I was able to change the res from something like 1300 x 768 to 1600 x 768. So now I am wondering if this is a settings issue or glitch, but since I dont have a spare computer monitor (only my 50" Kuro plasma tv) to check if its this setting causing the conflict does anyone else have any ideas? I have a 2nd gen MBA and a very old white 24" intel imac and a USB hub and a external harddrive. Is there an A-team / Macguyver home fix for this (as in trying to adjust the res settings) or do I have to wait and try and take this into the repair shop this week?
