Hi forum, I have installed Win7 (boot camp) to my rMBP and the process was alright. However, when I plug my rMBP (Win7 under boot camp) to an external display via displayport->vga, the maximum resolution I can get at the external is 680x480. I cannot adjust any display setting in Win7 (as attached). The external works fine on OSX. Has anyone of you encountered this problem before? I tried several external displays already so I am guessing it is the 650M driver issue but I am seeking more opinions. Thanks.
