Ok I have an Nvidia GeForce 295 gtx (1.7gb).. When connecting to my 1080p TV via HDMI cord, for the resolution native to my TV it show 1920x1080@50hz. My TV will not display anything at 50hz... If I say change to custom resolution, it works, but I get an issue where it needs to be calibrated because it has this one off pixel issue and shadows everything... causing weird graphics issues(shadowing and auras). Suffice it to say, I just want my pc to identify the 60hz mode so it will run it properly.
