Hello, I won a EVGA GTX 550 Ti GPU on eBay and I installed it and it works fine but the I can not set my monitors resolution. I have HP w1907 monitor it's resolution is 1440x900 it worked perfectly on the last GPU (9500 GT). As soon as I installed the new one I got the its driver from the Nvidia site and restarted. It has almost every resolution option except the one I need. I reinstalled Windows hoping somehow that would fix it but it didn't. The monitor I'm using has VGA and DVI-D ports and the GPU requires DVI-I or HDMI so I'm using a DVI-I to VGA adapter. Maybe that's the cause of it?
