I connect the pc to a TV (Samsung Plano wide 100 Hz Digital CRT) using s-video. The video card is GeForce XFX 8500 GT PCI-express. The only screen resolutions I can use are the typical 800x600, 1024x768 not the wide, and the refresh rate is 29 and 30 Hz. I had the same problems using Win Vista.
The thing is that in the past, I use the same TV with an older pc using an ATI VE RADEON video card in AGP 4x slot with s-video and Win XP. I could use wide resolutions and refresh rate up to 100 Hz using ATI catalyst.
I am going to buy a new wide LCD TV with VGA in, DVI in, HDMI in etc in the future, but until then?
