Random brief blackscreen

[dubchitts]

New member here, and first time PC builder. I've done tons of searching around the web and can't manage to fix my issue, and nvidia support is taking forever to respond

Build:
Mobo:msi mpg x670e carbon wifi (current bios)
CPU: amd ryzen 9 7950x
GPU: msi gaming x slim white 4080
Ram: ddr5 g.skill 64gb (f5-6000j3036g32gx2-tz5nrw
Ssd: Samsung 990 pro 2tb
Os: windows 11(also tried 10 to rule out os)
Aio: Arctic liquid freezer ii 420 argb
Case: thermaltake cte c750 argb snow
PSU: be quiet! Pure power 12m 1000w(GPU utilizing the 600w12vhpwr connecter, fully seated, roughly 2in before a bend by either connector)

I got os installed, all the drivers for the Mobo, current driver for nvidea and GeForce. On the initial run I un-selected amd Radeon graphics driver thinking that was for their gpus and not the onboard graphics of the 7950x. (this has been installed and made this issue considerably better)

Basically my old set up featured a 2060 ventus and I was able to run, on the same screen 3840x2160 @120hz and it was perfectly happy to do it. (I don't mainly play highly intensive games on it, due to most settings getting reverted to low. Mostly play RL and do video editing/recording).
My new set up, does random black screen for 2-3 seconds and comes back. Never fully shuts down the system or anything. Lights stay on the GPU the whole time. It does this only on 3840x2160 @120. It can run 1080 @120, or it can run 3840x2160 @60 and be fine.
I ran dxdiag and it showed windows basic display adapter fault, which was caused by the Radeon graphics driver not being there. Installed, and that was replaced with AMD graphics driver or something like that, with no error. This immensely reduced the amount and frequency of the black screen. I made it through 20-25 min of gameplay without the issue occuring, and then it popped up again, not nearly as frequent, but annoying nonetheless.

The only thing I can think of at this point is I didn't check ram compatibility via MSI website (which that exact model isn't listed yet), but through g.skills ram configurator, which said it was compatible. I can't enable expo, or the whole system becomes unstable. Expo off and auto frequency has given me no system stability issues.
Nothing is overclocked or anything at this point. I have run ddu and done a complete reinstall of the latest nvidea drivers.
The 2 HDMI I have tried are ultra high speed and known to allow 4k 120hz on my Sony kd-55x85j (HDMI slot 4, same settings as my Xbox series x and old PC run).
I have updated my old PC nvidea driver to the current one to see if the issue would appear on that one, and it still runs like a champ. I am at a loss now as to what else I could check? Maybe unplug the system and remove/reinstall the GPU?

Sorry for the Long af post, just trying to run down everything I've tried this far. Please help if you can lol!

Hello dubchitts,

If I understand correctly you're trying to run on a Sony TV, the model mentioned in that post. In that case there might be 2 situations: either the cable itself si not so great (it happends), or you try to run 4k@120Hz in Chroma 4:4:4 which is not supported on a PC connection. Try to run it in Chroma 4:2:2 and see if it happends anymore. For that go in Nvidia Control Panel-> Display->Change Resolution, scroll to the bottom, change to Use Nvida Color Settings instead of default, select Output Color Format to YCbCr422, output color depth 8 bit. You may also try both dynamic ranges, full or limited.

I Hope that helps.

It is not RAM. It is wise to check the motherboard's website for RAM compatibility but unlike CPUs, there are just too many RAM makers and RAM models for board makers to test them all. So you don't have to buy listed RAM, but you do need to buy RAM with the same specs as listed RAM to ensure compatibility. You apparently did that.

this only on 3840x2160 @120. It can run 1080 @120, or it can run 3840x2160 @60 and be fine.

That sure suggests issues with the graphics solution, or the monitor (TV in this case).

When troubleshooting odd hardware issues, I always want to verify I am providing good, clean, stable power since EVERYTHING inside the case depends on it. So I swap in a known good supply to see if the problem remains, or goes away.

In your case, I would also try to find a different monitor.

I might also purge the system of all graphics drivers, reboot (important!), then start over installing the correct drivers.

Thanks I will try that tonight!

Couldn't the monitor/tv itself and HDMI be ruled out since both can run the resolution on 2 different systems? I don't have another TV/monitor at the moment that I could try it on, and with Christmas coming up I can't spend anymore on it to try and fix this.
I could try the ddu again (maybe I did something wrong the first time)

With the mention of the color format, I know that is set to auto on the TV. Should I match that just to double check? Again the TV is set up the exact same way as it is for the other 2 systems. One being a Xbox series x and the other being my other PC, both run the same resolution with no issues.

Most likely that is true. But in my mind, not with 100% certainty. I would want to be 100% sure - at least before I spent money on something else.

So I don't have the 4:4:4 or 4:4:2 options available through the nvidia control panel. The issue has slowed down since the install of Radeon graphics, and I still don't have a 2nd monitor to try (seeing if any friends can bring one to try, might see what my work ones like lol)

Is there a list of drivers that are absolutely necessary somewhere that I can run through and double check, or any settings that may be I overlooked?

There's no way you do not have that setting. Also, RTX 2060 was never able to run 4k120 over HDMI simply because it was 2.0b which was limited to 60 Hz. And again, it has nothing to do with the Radeon graphics.

Random black screens could be a bad ground from the HDMI cable, reason i still post this is due to having the same issue kind of.

I thought the monitor was faulty ( AGAIN ), already replaced the main board in it 6 month before. Anyways in games it's would go black come back on after 2-3 seconds very randomly and it would never do it using our ROKU same resolution same refresh rate, but one day it just got real bad and when i took the HDMI cable out from the monitor which i had done a few times before over the time the ground casing came off.

Replaced the cable and not had the issue since, yeah i see you tried 2 cables but maybe they are the same brand or the soft casing type which seem to have the freedom to break easier.

All so note that my monitor is on thew wall too so table movement was moving the HDMI cable, it was really just like your issue as it never did it while using another device ( like the ROKU ).

All so why it might of stopped for a while could be you pushing the cable in making a better connection and over time goes back to how it was..

Just a thought.

I apologize, I thought 4:2:2 was in the resolution, so I simply looked in the wrong place! Now that I've checked the right place I have access to 4:4:4, or 4:4:0 it looks like. 4:4:4 is no good(like you said). 440has been fine for like 10 min. Will report back later

So running YcbCr420 has seemingly cured it. Desktop idle had no issue, ran star field for a little over an hour with no screen flicker.

Thank you so much!

Well, let's hope that was all, glad I could help!
