I have a 2011 2.7GHz Quad-Core Intel Core i5 with 12gb ram. I installed Windows 7 professional and am having some issues. The main one is, I can't get the resolutuion higher than 1920x1080 even though the imac supports 2560x1440. I have read all around the net about this and no one seems to know the exact fix. I did all the updates. I installed the bootcamp software after I installed windows. I did all the windows updates and I still can't change the resolution. Other than that, there are small issues like it not recognizing the keypad on my apple keyboard, and stuff like that. I don't really care, I am just looking for the resolution fix for now. It currently looks awful. Thanks for you help.
