Clouds of white dots in dark patches when gaming

[Rmarrtyr]

I recently built a new gaming PC (Specs below) and am experiencing strange clouds of white dots when playing games. I have noticed this on RDR2, Far Cry 5 and Doom Eternal (it's especially bad in Doom).

 

I've tried changing the graphics settings on each game but nothing seems to make a difference. Drivers are all up to date. Do I have a faulty card?

I thin kit could be artifacts but I'm not sure they would limit to dark areas.

You can still give a try to standard specs or even downclock a little to see if still does it.

Otherwise, I do not know, sorry.

Probably. If I saw something like that with a brand new graphics card I'd RMA it instantly.

Ok thanks, I thought as much.

Light dots on light content isn't as obvious.

 

It does remind me of things I've seen when overclocking a GPU, more leaning towards the vram. If you underclock it and it goes away that would confirm it. This is not expected for a new card and is reasonable to get a replacement.

Did you try another display cable?

 

I would get lots of red dots and sometimes display blanks when I upgraded to my 2080S. Swapped the HDMI cable and all was good, even though the cable that was there worked just fine with a 1070 and a 970 for years, somehow the drive must be weaker on the 2080S.

In case anyone else has this issue, this usually happens due to your gpu outputting a different RGB range than your television is set to accept.  Your blacks are getting crushed, resulting in these white sparkles. 
 

Both devices need to be set to either “Limited dynamic range” (GPU) / “Low Black Level” (TV) or “Full dynamic range” (GPU)  / “High Black Level” (TV). 
 

Full can use any RGB value between 0-255. Limited can only use RGB values between 16-235. Full is ideal for PCs as they usually use monitors, but all movies and videos, including HDR, are made for Limited/Low Black Levels, which is the TV standard. Full will actually make your blacks look gray and washed out for movie/video sources. 
 

On an Nvidia GPU, open Nvidia Control Panel. Under “Display”, open “Change Resolution”. At the bottom of that panel, you should see something about “Apply the following settings”.  You can change the dynamic range there. It’s set to full by default. 
 

On your TV, you need to set your black levels to match your GPU setting, as stated above. 
 

In order to get the full range from my PC without affecting my cable and movie inputs, I ran a dedicated HDMI cable between my PC and my TV on a dedicated input set to black level “high”. I tested with my PS5 and Xbox Series X, and both were best with the TV set to black level “low”.

Thank you so much for this! I have intermittently had issues with this in certain games and have had them disappear/appear with driver changes so I always thought it was a software issue. Just bumped my black level to high on my TV and fixed it immediately!!!
