I have a 46 inch Samsung LCD TV with a computer input and i would like to use it as a monitor for my computer. I bought a Vga cable with 2 vga male connectors on each side. I connected one side into my tv and the other into my NVIDIA 7900 GS (there is a converter on the video card, converting the DVI output to VGA). When originally started up the windows loading screen appears on the TV, but right after that a message on the TV says no input detected. I was wondering if anyone knew a way to fix this, maybe by changing some video card settings? Any help would be greatly appriciated!
