NEW ISSUE: - EVERYTHING is on Stock. Stock memory, stock CPU, debug mode GPU.
 
When performing ANY stress test of any kind, the GPU cuts the signal. Again, all I have to do is disconnect and reconnect and it works and tasks being performed continue to run.
 
- The CPU temps are under 50 (due to stock)
- The memory has passed tests
- The OS HDD has passed tests
- Latest BIOS and drivers.

Any ideas?

 
As the title says, my GTX 1080 FTW loses signal. The fix is to unplug the cable and plug it back in. It's fine under the games I play (CS:GO and a few others) but it's annoying.
 
What happens:
The monitor turns off due to no signal being detected. 
 
Tested:
CS:GO
GTA V
Other games
Blender
 
Fix?
Fix appears to be unplugging the cable and plugging it back in (on the GPU, not the monitor)
 
Overclocks?
Removed overclocks from CPU, RAM, and GPU - same issue.
 
Drivers?
Happens under different drivers with my GTX 1080 only.
 
Event Viewer?
Nothing mentioned.
 
Can it be reproduced?
Yes, Blender appears to always cause it, but it happens under certain games as well.
 
Do I think it's the same as the "EVGA BS" issue?
I don't think so but I'm not sure. It's apparant that EVGA does not believe in Quality Control so I have no faith in the card.
 
Other components tested?
RAM passes tests
HDD passes tests and SMART info
Temperatures are more than acceptable
Dust is minimal and filters are cleaned often
All parts are less than one year old
 
Would I like to RMA the card?
Not unless it's faulty, but then I get a pre-owned card and have to pay postage costs. I thought I'd ask here and hope an EVGA support guy would reply.
 
Have I contacted Support?
Yes. I called US support due to EU support only working office hours. The guys I spoke with couldn't have been less interested. He did offer to RMA the card, but then there's the costs involved and the idea of a second-hand card is not great.
 
Do I think it's the card?
I'm not really sure, that's why I thought I would ask on here.
 
I hope the above is in a clear format. Thank you for taking the time to read.

    Are you using the dp cable that shipped with your monitor?

    I've tested two cables - one that came with the monitor and one I purchased from eBuyer. I have read the EVGA FAQ about non-certified DisplayPort cables - is that what you're referring to?

    The dp output you're currently using may be faulty. Make sure to test the other dp outputs too.

    I'm now seeing performance issues in games where the FPS drops by 60% or so. I'm starting to think the GTX 1080 may have issues.

    Do you notice the drops when you have your in game settings set to the lowest possible settings?

    I'm now leaving the card on debug mode to see how that works out.

    I just had this happen to me while gaming for the first time yesterday. Black screen on both monitors. No fan speed increase. I had music playing in the background and it continued playing after everything went black. So wasn't a hard crash.

    Today it happened again while gaming. Same thing with the music continuing to play. Found this thread and unplugged the reinserted the DisplayPort and my 2 screens came back to life. Weird that my 2nd monitor is connected via hdmi but also rebooted after reinserting the DisplayPort to my main monitor. My game had crashed to desktop. Temps looked normal. Not sure what the problem could be. Maybe the game crashing somehow caused the black screen? Leaning to it being something with the DisplayPort. Idk

    Glad it's not just my card. Are you using the cables that came with your monitor(s)?

    Yes, using the DisplayPort cable that came with the monitor. Primary monitor is a Dell S2716DG G-sync monitor and using a EVGA GTX 1080 FTW. I'll update if it happens again. Curious to see if my game crashes to desktop every time the screens go black.

    Sounds like it's time to start an RMA, but EVGA Tech Support might have something else for you to try if you want to call or email them - http://www.evga.com/about/contactus/

    I actually see this problem from time to time on my own cards-  Dell monitors also, might be an issue with them honestly, some of them have had multiple firmware revisions to resolve DisplayPort issues on their forums.

    I have the exact same monitor and I am using the stock cable, so far I have had no issues. Running off a non FTW 1080 Hybrid.

    My rig: Gigabyte X99 SLI, GTX 1080 Hybrid, Corsair Vengeance 3000Mhz RAM, Intel 6800k, Corsair 750D Obsidian Airflow Edition, Dell S2716DG 144Hz G-sync Monitor, Deepcool Captain 360 CPU Cooler.

    All parts are less than a year old - the GPU being the newest.

    I have formatted and reinstalled Windows and stuck with the 372.90 drivers. So far, I've not noticed issues (in basic benchmarks). I plan to fully test the system.
     
    Is there a good way to replicate playing something like DOOM or BF1 without having to play it (not Heaven or Valley)?

    Time to test your games.

    I've played a few hours of CS:GO and noticed no change, but then CS:GO mostly worked beforehand. I've also tested 30 minutes of Fallout 4 (Ultra, UHD) and it seemed about as I remember.
     
    I don't have time to test games at the moment. However, I did go out and leave RealBench running on a stress test. I chose 8GB RAM for 4 hours - it passed without issue (this was a problem beforehand).
     
    This is very, very odd.

    Some graphics drivers can cause a black screen at the end of a realbench run. Looks like 372.90 isn't one of them.

    This wasn't just an issue with RealBench, but with any stress-testing software.

    Guess it's time to try some of those other stress tests as you've only mentioned realbench.

    RealBench
    Aida64
    IntelBurnTest
    x264 Benchmark (AVX)
    Intel XTU
     
    All of those have passed. Oddly, since testing a new driver, Heaven gives a 10fps average increase compared to the current driver. I'm not sure whether this is a hardware of software issue and that annoys me. The black screen in two games does seem to indicate hardware - and Jacob's explanation in the thread shows why this might cause issues only under certain circumstances.
     
    I'll continue to perform tests as I've lost faith in EVGA's RMA process after seeing the number of people who received defective cards after sending theirs back.

    I know you black screened when running in debug mode. Try using msi afterburner to underclock your card as far as you can to see if it helps get rid of the black screen. If underclocking doesn't help try running your gpu fans at max speed to see if it helps get rid of the black screen.
