Eye Strain - Temporal Dithering

  Hey folks,
Hoping the Dell team might be able to answer this.

I get really bad eye strain from some graphics card / display panel combinations. 10 minutes and my eyes hurt and I need to stop. From what I understand Temporal Dithering seems to be the issue. Not an issue with blue lights or something fixable by "night mode".

Temporal Dithering is when a graphics card has more colors than a display panel can support (eg. a 10 bit graphics card with an 8 bit display panel). When the display panel does not have enough colors, the graphics card will emulate (fake) the missing colors by rapidly flickering between two colors (blue plus yellow equals green).

I have an XPS 13 that had temporal dithering disabled from the factory. It is a good laptop, I really like it. Once I reinstalled the stock MS Windows 10 and the dithering was enabled in Windows 10 by default. Reinstalling the Dell factory image fixed the issue. - It seems the folks at Dell have figured out how to disable dithering. At least with the Intel Iris graphics.

I am looking at buying the New XPS 15 (i9-12900HK) with the Nvidia GPU. And actually did buy one with the FHD (1080p) display. Unfortunately that particular unit gave me eye strain and I had to send it back. I am hoping I can buy one that will not give me eye strain.

My questions: Can anyone tell me:
- How many colors does the Nvidia Geforce RTX 3050 Ti 4 GB GDDR6 45W support?
- How many colors does the UHD+ 15.6" 3840x2400 support? (Or is this a question that depends on which vendors display panel gets put in the laptop? Samsung, LG, AUO, ...).

Or even better:
- Does anyone in Dell support know how to disable Temporal Dithering with an Nvidia GPU?

Thank you
