Still having problem with soft15khz... I pressed "install 15khz" and it appears that nothing has changed. When I open quickres, I can only go as low as 640x480 even after restarting the computer. I am using an ATI Radeon 4800 HD series graphics card. Can anyone provide any insight? Is it possible that the lower resolutions are not showing up because I am using an HDMI cable to connect to a TV?
