Question Only one displayport works on my Gigabyte GTX 980

[danhaz]

Hi there,

I'm having a strange issue with my Gigabyte GTX 980, I was recently doing moving around a bunch of my cables and had to unplug my DP cable from my tower for a moment. I plugged it back into one of the three display ports not thinking too much of it and received a "No signal" message on my Asus VG248QE. After a bit of messing around I plugged it into the other two ports and found that only one of them allowed me to get my monitor to receive the signal. I did a little searching online and found a few tricks to try and bypass this. One being that it might be a monitor problem and I needed to unplug my monitor for a few seconds and replug it in which worked for some people but not me. I also thought it might be the cable, but I bought one of Amazon today and tried it in all three display ports but it still one only work on the same port for some straight reason. I'm not too sure what could be the issue at this point.

(Running off Windows 10)

Thanks for any help provided!

I have bought recently an "Dead" GPU (Gigabyte 950 OC ), after fiddling around with restarting and etc. I came to conclusion that it was bad bios. (it would either freeze my system during boot, or display and after installing drivers for first time it would not recover after restart or if it did it would show error 43 in Device Manager)
I've personally flashed the First bios i came to techpowerup.

As many reports especially the Gigabyte and EVGA 900 series have issues with only one Display working, I have reflashed the bios and its currently in working state.

Hey man, thanks for the response.

Is there a how to dummy guide out there on how to do this? I'm assuming you mean to update the gpu bios. I'm not that tech savvy when it comes to pc parts. If you have one that would be great.

-- SOLUTION --
Nevermind, ended up speaking to Nvidia support, they suggested I download DDU (Display Driver Uninstaller). I ended up running my pc in safe mode, removing my drivers, restarting my pc and installing an older version found here: https://www.nvidia.com/download/driverResults.aspx/141906/en-us (417.7 ). And now all my display ports work!
