I have my pc connected to a vizio 37" lcd using a DVI cable to the TV's hdmi port with a dvi/hdmi adapter..when I go to nvidia control panel there's no option to select the monitors 1366x768 solution..help me please how do I configure this resolution with nvidia control panel...i tested it using vga cable and it does work fine but not with DVI/hdmi adapter. My video card is an XFX 8800gt 175.16 drivers and I'm running Vista Ultimate 32bit.
