7950 dual monitor problems

post #1 of 26
Thread Starter 
Hi, I have a Sapphire Radeon 7950, I'm attempting to hook up a 2nd monitor to it. My main monitor is hooked up with DVI and I'm trying to hook the second one up via HDMI but there's no signal and Windows doesn't detect a 2nd monitor, neither does CCC. HDMI is my only choice for a 2nd monitor I believe since my graphics card only has 1 DVI port. Any suggestions? Am I missing something obvious? Thanks.

It's brand new, I only bought it today so I don't think so, I'll test a different one in case.

This may be a stupid question, but you plug it in with the PC off, right?

Does the 2nd monitor work with the DVI port?

Yeah I've restarted my PC a few times, to no avail. Going to try the DVI port now and also just the HDMI alone.

Ok so apparently my 2nd monitor doesn't even have a DVI input so I can't test that (it has VGA and HDMI). I tested HDMI alone but there was no signal. Starting to wonder if somehow my cards HDMI port is busted out of the box.

stupid question but did you change the source on your monitor to hdmi/digital? should be still picking up the monitor regardless, try updating your drivers

Yeah I switched between HDMI input and PC input but neither worked, already got the latest drivers. Maybe I should just hook up my 2nd monitor to my onboard graphics via VGA but I don't really wanna mess anything up by having 2 sets of drivers installed etc

In most cases your onboard gpu will be disabled with a dedicated gpu installed. I would try a fresh driver install for the heck of it

Well I can't even do that.

Installed onboard VGA drivers
Changed option in BIOS to IGFX-GFXO-GPP-PCI
But now I can't get my main graphics card/monitor working, yellow exclamation mark in device manager for my 7950 saying that Windows can't start the driver or something.

So I'm well and truly stumped.
