I have recently installed a GEForce 210 video card because of its VGA/DVI/HDMI connectivity. The VGA connection to monitor is fine, HDMI to TV perfect, but DVI connection to monitor does not work.

I have eliminated cable as a source of problem by putting my cable into another system and seeing that system work properly.

I am running Windows 7 and the monitor is AOC 21" 2236Vw LCD with 1920 X 1080 resolution.

I have updated the drivers for the card and the monitor, but no difference.

Would be grateful for any suggestions.

By the way, the AOC instructions advise connectiong DVI and VGA cables simulatneously. That seems weird to me - anyway have tried DVI and VGA together, and DVI by itself without success.
