Gaming in dim areas with numerous white specks appearing on screen
I recently assembled a new gaming PC with the specifications listed and am encountering unusual white dot patterns during gameplay. This issue appears in RDR2, Far Cry 5, and Doom Eternal, being particularly noticeable in Doom. I've adjusted the graphics settings in each title but haven't seen improvement. Drivers are current. Could there be a problem with my graphics card?
It seems the issue might be related to artifacts, though I'm uncertain if they're confined to darker zones. You could test with typical settings or slightly lower performance to check functionality. If unsure, I can't confirm further.
Likely. With a brand new graphics card, I’d send it back right away.
Light dots in bright areas aren't as clear. It brings to mind observations from GPU overclocking, especially regarding VRAM usage. If lowering the clock speed removes the issue, that would support the explanation. This isn't typical for a brand-new card, so replacing it seems sensible.
Have you experimented with a different display cable? I noticed a lot of red dots and occasional blank screens after upgrading to my 2080S. I changed the HDMI cable and it worked fine, even though the same cable previously functioned well with a 1070 and 970 for years. It seems the drive might be less powerful on the 2080S.
If you notice similar problems, it’s often because your GPU sends a different color range than your TV supports. This causes blacks to fade and white highlights to appear. Both devices should match either “Limited dynamic range” (GPU) or “Low Black Level” (TV), or vice versa. Full dynamic range lets the GPU handle any RGB value, while Limited restricts it to 16-235. Full works well with PC monitors but is standard for TVs. Full settings can make movie or video blacks look gray and washed out. On an Nvidia GPU, access the Control Panel, adjust “Change Resolution,” and set the dynamic range to full. On your TV, align your black levels with the GPU’s setting. To ensure consistent blacks without affecting other inputs, I connected a dedicated HDMI cable to my PC and TV, using the TV’s “high” black level setting. Testing with PS5 and Xbox Series X confirmed this approach works best.
