HI. So I recently upgraded my Asus Radeon HD 6670 to a Asus gtx 760. I've always used my 6670 on my 1440x900 monitor connected via a vga cable. Since their was never any vga output on that gpu I used a dvi to vga adapter and it worked just fine. Now I've fitted and installed my gpu with the lastest drivers and I've got the vga plugged in through the dvi adapter. And when I go to screen resolution my 1440x900 isn't there. I go to the nvidia settings and create a custom res of 1440x900 but it looks really blurry and wrong. Whatever I do I can't get it to look right through anyway. My monitor is 1440x900 and my gpu is Asus GeForce gtx 760. Thanks
