I'll add myself to this list...
I also have the 'screen goes black for up to 5 seconds, then comes back.
This never happened until like a month ago.
I have Windows 11 (full version, not 'insider' beta):
Intel NUC12DCMi9 - the toaster sized Intel PC with i9,
32GB ram, 1 TB SSD, and EVGA RTX 3070 Ti
It happens regardless of use - like twice while reading through this forum post...
When it happens while gaming - it is a nightmare, sometimes causing failure of fight - not good for such an expensive gaming system. This is my Media pc - connected to my 4K TV via HDMI on feedthrough of my Yamaha RX-A8A 7.1.4 Dolby Atmos surround system.
It ran from last July through January with 0 black screens... now at random, minutes to hours between, load independent, with latest Nvidia drivers.
My guess is a recent driver change - since it is new on my PC.
Update: A week after posting this and messaging/talking with EVGA support, their only guess was lack of power, so I decided to make sure it wasn't the lack of power in my Intel NUC12DCMi9 with it's integrated 650W power supply - so I purchased a Thermaltake Smart 430W power supply, and a cute little ADD2PSU board that receives the NUC12DCMi9 Molex 4-pin power cable that acts as a switch to instantly turn on the 430Watt power supply when PC power comes on for $54. Now the EVGA RTX is powered from its' own power supply. No difference - proving it was not lack of power.
Solution:Next attempt as
lascivious1 had suggested above, I purchased a new HDMI cable:
I bought a "Highwings High Speed
8K 60Hz HDMI Cable
3.3FT/1M,
2.1 48Gbps HDMI Braided Cable" from Amazon - the important considerations were 20,000+ 4.7 star reviews and 8K 60Hz/4K 120Hz support as there are many cheap 8K cables listed that are older 4k/1.1? cables relabeled for profit.
This worked - I have had zero black screens since upgrading to this cable!
