Anyone else experiencing the same issue? after updating to 10.5.7 i got a grey band across the bottom of my screen after restart. I logged in and went to system preferences, but the highest resolution i can now choose is 1920x1080. My screen is a HP w2448hc, its capable of 1920x1280, worked at this res before update. Anyone suggest a fix? or did they restrict the mac mini in the update? Many thanks in advance.
