Can't get DVI working with my 5850, VGA only

My system:
Gigabyte 5850
Sceptre X24WG (24" LCD monitor, 1920x1200)
Corsair HX650W
Asus P5N-D
Q6600
4GB Ram

I just bought this 5850 and when I hooked the card into my monitor and fired up my PC, there was no picture. The BIOS beeped indicating a normal POST and Windows booted normally, but I still had no output on my monitor. I was convinced that the card was defective (not entirely unconvinced yet) until I tried VGA. It all worked perfectly! I got an analog picture.

However, since it's VGA, the picture's a bit fuzzy. I really don't understand why DVI won't work, when it worked with my old EVGA 8800GT perfectly. I checked the BIOS version using GPU-Z, and I seem to already have the latest. Anyone know what's going on? Should I just RMA it? Or is there something I can do to the card to make it work?

EDIT (Feb. 2012): For the sake of closure, it was the monitor's fault.

Can you put the old 8800GT back in and see if it works fine? If it works, then RAM the 5850.

Also, plug in both DVI and VGA and manually try setting it to DVI via the OSD on the LCD.

Well, the 8800gt is broken, except for safe mode, but I'll give it a try. As for your second idea, I already tried that, it wouldn't detect it the monitor. However, it I hooked it up through my Sony surround sound reciever (via HDMI), it did work digitally (at 640x480...)

Well, the cable I was using worked for about 2 years with my old 8800gt, but I did check with all my other cables with the same result. I think I'm just gonna RMA it.
