My current build is :

Gigabyte Z170X-Ultra Gaming motherboard.
Intel i7 6700K
Corsair LPX 32GB 3200Mhz DDR4 RAM
Gigabyte GeForce GTX 1050 OC Low Profile 2GB (GV-N1050OC-2GL)




My OS is currently running Mac OS X Sierra - 10.12.5 with iMac 17,1 definition.
Using LILU (1.1.5) and NvidiaGraphicsFixup (1.1.2) and AppleALC (1.1.2)
Updated Clover to 2.4k 4259

BIOS - Disable Integrated graphics - Set PEG as Primary.


Everything runs smooth on this machine, no problems except this one.
Only this problem related to one of the displays, or both of them goes suddenly blank and comes back on. RANDOMLY.. This happens mostly when working in Illustrator, and or Photoshop but sometimes just in Finder or Chrome, too.
Completely random.

I have recorded what happens here in this video :


The left display is a 27" Dell Ultrasharp connected with DP to DVI on the GTX card.
The right display is a 24" Dell Ultrasharp connected with DP to DP on the GTX card.

I have tried the HDMI connection also on both displays, it doesn't change anything. This randomly blank issues happens no matter what. Mostly (I think), when doing something releated to using the GPU.

Has anyone encounter this?
Some help would be much appreciated.

BTW, I built 2 of these machines exactly the same. But the other one has a GTX 1050 Ti(GV-N105TWF20C-4GD) card which has 4GB in RAM. That machine does not have this issue. Only this GTX 1050(GV-N1050OC-2GL) with 2GB RAM.
Same OS, same drivers. Same Clover config.

BTW, this machine never goes into sleep. The Displays goes into sleep after 10min, but the machine itself no.

Could this be VBIOS bug?
https://www.gigabyte.com/Graphics-Card/GV-N1050OC-2GL#support-dl
On the gigabyte page, they say that F3_Beta BIOS released 2017/08/07 has the following release notes :
1. Release for SKHYNIX Memory
2. Nvidia Source BIOS Version : 86.07.39.00.8A
3. Base/Boost: 1366/1468Mhz
4. TGP: 75W
6. Increase Stability
7. For F1~F3 BIOS FLASH



This problem looks just like these :

I’m running a gtx 750. 2x benq monitors. One on hdmi and one on a dvi-hdmi converter.
It didn’t do it in Sierra or it doesn’t do it when I boot into windows 10.

It’s always the same screen that goes off ( the one without the adapter ).

Running High Sierra with the suplimental update. With the latest Nvidia web drivers.

Okey, but I'm running Sierra 10.12.5 and not High Sierra.

Is this completely gone in your case ?

It appears to be. I used it for about 4 hrs last night after doing the updates. Changed nothing else and it didn’t do it once.
