I have my new MBP hoooked up to a Dell 2005fpw and it normally runs at 1680 1050 when hooked to my PC. I have it set to 1680 1050 on me MBP but its lying if I take a screenshot of my desktop its 1440x900 if I load an image that 1680 1050 it is way bigger than my desktop, if I play harvest half the game is off my screen. What can I do to get it to really be 1680 x 1050? See attached image. THANKS!!
