In my experience, not all HDMI cables are equal! If you are using a HDMI cable, make sure that it supports resolutions higher than p. The specs for the GeForce GT clearly state the max resolution supported is xso what was the problem? Firstly, go to the NVIDA website, search for your graphics card and make sure that the custom resolution you require is listed in the specifications. If your monitor and graphics card support a higher resolution such as x but Windows is not showing anything higher than xyou may be able to force a higher resolution using the Nvidia Control Panel.
