Connect just the 1 monitor with VGA cable to the VGA port on the HD4350. What do you get? No display whatsoever? Nothing?
If so, the port is likely toast, unless the cable or monitor are bad. Sounds like you can already confirm the cable and monitor are not the issue, however.
In total, what outputs are offered on the back of the video card? DVI, VGA, and? Anything else?
