GeForce 7900 GS - no DVI output?

[mister ed]

I am stumped, I have worked with this for two days now. I recently purchased a XFX GeForce 7900 GS graphics card, and when I connected the DVI to my LCD I got no video output whatsoever, no POST output or anything. I tried a different card and got the same thing.

When I attached the DVI to VGA adapter, it started working. I have loaded the most recent drivers and still no luck. My monitor is widescreen and I cannot get to native 1680x1050 resolution in VGA mode, anyone got any ideas?

That's weird if it happens with another card too - would kind of signify that maybe it's some issue with the monitor, although if it works with an adapter that's odd too.

Have you had it working before with a previous card at that resolution and with DVI? Or is the monitor recently purchased too?

The DVI port on your LCD may have died.

It happened to my 22" Acer.

Happened to my 17" Dell LCD too.

no, the dvi port is good on the monitor, I hooked up my powerbook's dvi out and it worked fine.....

so weird.

nothing has worked. I am certain the monitor is fine, I'm wondering now if it's a motherboard issue, possibly the pins on the PCI E slot are bad or damaged? Could that cause a problem like this?

I've built dozens of systems and I've never been this frustrated. Any help is appreciated.

dvi cable is bad? drivers are bad?

dvi cable works, I can hook up my powerbook to the monitor over DVI no problem.

The drivers are beta, but shouldn't I see the bios splash screen and post info at boot before the drivers load? it just acts like there's nothing connected.

There might be a menu option on the monitor to select analog or digital input.
