Win 11, using 100 % scaling reduced eye burn

Vedic-Dance

Hi.

At 150% scaling, I experienced a burning sensation in my eyes while using my laptop screen. Reducing the scaling to 100% helped relieve the strain. I’m sharing this in case others find it useful. Here is an explanation of why this happens, according to an LLM

Windows 150 % scaling

$$
UI → fractional resample → blend → dither → panel FRC
$$

Multiple steps where:

gray levels are synthesized
values are temporally modulated

Hardware Info:

2560 x 1600 16"

Interesting. For me UI-scaling in Windows is not an issue. It is in Ubuntu though.

What helps me is to disable scaling in the graphics driver. From "Full" to "No scaling". This can be done in the NVidia and AMD drivers.

Think this is because the graphics do not match the pixels of the screen when scaling is applied and it uses subpixel antialiasing ( assumption ). Subpixel antialiasing in font rendering is also a problem for my eyes. Greyscale antialiasing fixes it for me ( Ubuntu, Chrome-based browsers )
