AMD Radeon HD 6450. Not running 2 display's?

[Jesse Bosnjak]

I've bought this video card about a month ago and installed all the drivers and kept them up to date with a single monitor. Now i have plugged in my other monitor into the DVI port, it is not detected.
I have a 400W power supply and my card requires 400W. not sure if i dont have enough power to run them both or not.

Unplug the monitor that works. You need to make sure the port, cable and other monitor work.

What's the max resolution for this card?

Dual-link DVI with HDCP
Max resolution: 2560x1600

VGA
Max resolution: 2048x1536
The monitor that in the vga is 1680x 1050 and the DMI is 1440x900
i have tried both monitors in the dvi. and non of them work

Only 1 monitor in, both monitors don't work in dvi with different cables? Then I'd have to say the dvi port is bad.
