DaVinci Resolve Studio 20 + RTX 4060 Ti – FIX for UI Flickering / Black Squares via NVIDIA Control Panel

If you're experiencing UI flickering, black square artifacts, or visual glitches in DaVinci Resolve Studio 20 while using an RTX 4060 Ti, these NVIDIA Control Panel settings completely fixed it for me:

Steps to fix it:

Open the NVIDIA Control Panel (right-click on desktop → NVIDIA Control Panel).

Go to Manage 3D Settings.

Under the Program Settings tab, select DaVinci Resolve from the list.

Apply the following settings:

Key settings to change:

Vertical Sync: OFF

Texture Filtering - Trilinear Optimization: OFF

Texture Filtering - Anisotropic Sample Optimization: OFF

OpenGL Compatibility: Prefer Compatible

OpenGL Rendering GPU: Manually select your RTX 4060 Ti

Power Management Mode: Prefer Maximum Performance

After applying these settings, all flickering and UI issues were gone for me.

Hope this helps someone else out there! It saved me a lot of frustration.

Vertical Sync is the nr. 1 that needs to be disabled to fix this annoying blinking.

Thanks. I will try this and report back.

edit: seems to work

also followed more advise about 10bit displays here
