Hello all, I've got a reference EVGA GTX980Ti connected to my LG 24GM77 display using a Display Port connection.  In Windows, I have the monitor set to sleep after 10 minutes and power to the PC is always on (sleep time set to Never).  Sometimes, when I come back to my PC and wake the monitor, I will get a corrupted display that looks like the pictures attached.
 
It doesn't happen every time I wake the monitor, but often enough to start bugging me (I'd say 1 out of 10 times).  A simple restart and everything is back to normal so I don't think it's a hardware problem.  Plus, I've never had this happen with normal use - only sometimes when the monitor goes to sleep mode.
 
I've got the latest 361.91 NV drivers installed (but this has persisted over several of the previous releases as well).  I run Afterburner 4.2.0 with a moderate overclock (+100 core/+200 memory) and the card has been very stable with benchmarks and hours of gaming.  I've tried a few different display port cables (one Startech and two Mono Price) but the issue still persists.  I've also tried switching to other display ports as well and that hasn't helped.
 
Anyone else experience this as well?  Any thoughts or suggestions?
 
Thanks in advance. :)

You may want to also test with a different refresh rate and resolution combo. Have you tested the graphics card with stock settings?

Thanks for the replies! :)
 
OK, I'm going to give DDU a go and reinstall drivers as you guys suggested.
 
@NO_sauce, @bsmegreg interesting you guys mention the DP cable.  I've been googling like crazy over this and I've come across some discussions about the quality of display port cables.  I've ordered one that's properly certified by displayport.org this time so I'll see if that helps.  It should be here later this week.
 
Thanks again for the help.  I'll start with the reinstall and new cable and see how it goes.  This is somewhat of an intermittent issue so it's going to be some time before I can say for sure if it's fixed so apologies in advanced for delayed replies.

Hello all, sorry to dig up an old post, but I wanted to follow up on this issue in case there was any one else out there having the same trouble.
I have been using the Acell display port cable (linked above) that's certified by displayport.org and haven't experienced this issue since.  It's been easily long enough that it would have recurred by now, so I'm going to say this issue is resolved. :)

Hey there... I have EXACTLY same issue...Just like on your screen shots! Tried 2 different cards at this point GTX1060, and now on  GTX1070, so its not a GPU for sure.
What we do have in common - is the SAME monitor - LG 24GM77. I never had this issue happen with my old R9 280X, and the same config... even used same DP cable.. go figure.
 
Could it be MSI Afterburner?
 
Even tried clean  windows re-install.... Please let me know if you are still clear of issues!?

Sorry to hear that. 
Since my last post, things have been going well for the most part.  However, around early June it did it again.  I will say, the new Accell cable made a big improvement on my end since I went several months without a problem (otherwise was like a weekly occurance previously).  No problems otherwise though.
 
Also, I don't have my LG display anymore.  About a month ago, I picked up a Dell U2515H which has only DP and HDMI inputs.  I've been using display port on the Dell with the same Accell cable and have had zero troubles with it thus far.
 
I'm not sure what to suggest though...I never really pinned down the exact cause.  The cable certainly did help big time, but wasn't perfect.  Maybe a combination of things (say monitor, cable, GPU drivers combination?)

Your new monitor, I am guessing it doesnt support 120 / 144hz... maybe that is the issue.
You are literally, the only person, i had found with the same issue... I will be trying to turn MSI Afterburner off, if that is not the case, switch to DVI cable, and if that doesnt work switch to 120Hz... Then its monitor I guess.

Yep, my Dell doesn't support 144 Hz (just a standard IPS 60Hz 1440p display...change in priorities is all).  Might be worth running 60Hz for some time if you suspect that's the culprit.  Could be an issue with Afterburner too, but it's doubtful IMO.  It's such a popular program I think we'd hear more about it if there was an inherent problem.

The 417 drivers do the same thing. I'm having the exact same problem:
 
EVGA 980Ti, Asus PG27AQ, Display Port connection.

Hey there, I have the same issue with:
GPU: Asus GTX 1070 Strix
Monitor: Acer 27" Predator XB271HU G-Sync
 
I believe the DP cable came with the monitor.
Anyways, I've had this problem for many years. No idea if it's fixable or what's causing it. I too use MSI Afterburner, not sure that's a common denominator but I do use it.
 
It happens rarely, but it happens. Only on waking the screen after it's been put to sleep (NOT hibernation in Windows).
 
When it happens, if I unplug the DP cable from the GPU, the system hangs completely.

Cool GTX
 
Have you tried this tool ?
 

I have not, at first glance it seems to only regard booting.
However, I downloaded it and it wanted me to do a firmware update, so I did. Time will tell me if it fixed the problem! Regardless of description, it doesn't seem far fetched that it could work.
