I have last gen C2D Mac Mini hooked to my 37" 720 LG TV through the DVI > HDMI. I only use the Mini for music and movies though NetFlix etc. Last night I did updates to OSX etc and after reboot my rez is all messed up. Apple toolbar just slightly off screen and I can't seem to find the proper rez. Before the Mini set itself automatically to the LG's rez, but not no more....but it does see it is connected to a LG TV. Any ideas?
