I put this in GPU because it could be a problem with my graphics cards. It could also be a problem with my main display, or with the specific software I am using - I will let you be the judge.
First, my specs:
I had some issues connecting my Vizio Smart TV to my graphics cards before, an issue a lot of people had. It worked for me for a while, but then I moved my PC (and didn't try connecting again for a while), then tried with a 30' cable and I get no luck on 2160p, though it does work at 1080p. The problem there when trying to connect at 4k is the the PC never even recognizes that the Vizio is connected. What I decided was most likely the issue was cable length, and I decided connecting to my living room pc wan't all that important - I did not try moving equipment so I can use a 6' cable again. That means I am not 100% sure of my graphics cards though. On a day to day basis I see no issues. I am inclined to think the following issue is related to my Samsung Smart TV (used as monitor) or the game I am playing, GTA V / GTA Online.
What happens is that the game will randomly crash after a period of time, it loses responsiveness (freezes) while audio remains the same. Desktop / Windows showing on my other monitors is unchanged and things run fine - just anything on my center display is not visible. After a few seconds, the game turns white and I get a Windows crash report (for the program, not my system). From then on, if I relaunch, I get random loss of signal from my monitor - the screen goes black for a few seconds, then returns. Sometimes I get the "No Signal" blib. If I reboot, the problem goes away until it crashes again. I'm unsure of issues which would show up only once a piece of software had crashed and would cease once system reboot occurs, I am thinking this might be potentially a GPU issue, if the game is pushing the graphics cards too hard it could potentially be that their factory overclock is not stable? No other game I play currently is as GPU intensive, as I am playing GTA V at near-max quality at 4k resolution. I suppose it could be something in the GTA V software though, that both causes the initial crash and that crash causes the system to run poorer until reboot... I am unsure. The game is quite buggy at this point so it is hard for me to tell if its a hardware problem or not.
I will also add, that before adding the Samsung display to my setup and before the release of GTA V I was having intermittent loss of signal to both of my monitors at the same time. This typically happened in World of Warcraft (mid raid fight, of course!), and what would happen is I would lose all signal to my monitors --- they'd go completely dark with no message. Audio remained the same, my PC would continue to run the program, and I could actually keep playing "in the dark" and have control over my character like normal, and continue speaking (with push to talk) over a VOIP client. I could not get my monitors to continue displaying video without a reboot however. I rolled back my graphics drivers and it seemed to fix the issue (trying to get that one resolved, I did a complete OS reinstall, checked all of my drivers, firmware, BIOS versions, etc.). At that time it was just WoW at 1440p running at over 150 fps with no real stress on my system. That's another reason why I suspect my graphics cards. I can easily RMA them but I do not want to spend weeks without them unless its obviously necessary. What's happening now however is different in that I do not lose signal on all monitors, just the main display (which had been running the game) - and all displays are connected to the same GPU, although the Samsung is the only using the HDMI 2.0 port.
Anyhow, any thoughts on this issue and what might be causing it would be very much appreciated. I would like a stable machine, generally I have no issues (aside from the very rare Windows 8 BSOD).
First, my specs:
Asus Z97 Pro Motherboard
Intel Core i7 4790k [software overclocked to 4.7 ghz on all cores]
Corsair H110i Closed Loop CPU Cooler
Corsair Vengeance 1866 mhz RAM 4x8GB Dimms (32 GB)
SLI EVGA GTX 980 SC ACX 2.0
Corsair AX1500i PSU [1500 watt 80+ Titanium - purchased for powering a 295x2 card which I sold]
Samsung 840 EVO SSD
Windows 8.1 64 bit
Side note: I have a Corair Air 540 with Silverstone AP fans. Generally my temperatures are very very good, with extremely high airflow. CPU cooler exhausts out the top and I have front intake / rear exhaust as well. I do not think temperatures would be causing the issue. I have my fans set to remain at low RPM until 60 degrees C and then ramp up, and I very rarely hear them ramp up.
Displays:
Primary - Samsung UN40JU6700 Smart TV
Side Displays - Overlord x270OC 27" 1440p, Asus VS236h 23" 1080p
