[My Solution] Chromebook

For the first time in ~5y I have discovered a screen that I can look without discomfort at all - Samsung Chromebook 3 XE501C13-K02US (Intel HD Graphics 400). I was waiting week+ to make sure it's not the optimism before I write this I've been 12+h a day online without my daily eye burn

I have eliminated many factors, but still need help to narrow it down!!

It's screen is 11 inch LED mate. Since it's small I connect it to a Dell ST2410b (2-lamp direct CCFL lamps as opposed to the 4 lamps used by conventional monitors).
Both monitors the laptops and the external CCFL feel same to me.
I'm mainly Mac user (retina and air). This monitor (mate) turns bad with both my laptops.

F.lux does not make difference for me. The monitor is CCFL. I always weare AMber Gunnars when in front of screen as it improves a lot the contrast for me.
Sooo the issue is not with LED and blue light

The chromebook is 60HZ, when point camera to it it flickers like crazy. I dont get strain and migraines. I don't have problems being in the office with 10+ fluorescent lights around me as long I dont look at a screen.
Sooo flicker, PWM are not issues for me.

I dont suspect on the fonts either, as non of the browsers I have tried worked for me. Also besides browsers, I use lot of terminal, sublime...each of them has different font and I can feel the discomfort instantly withing 2-3 seconds with fresh eyes.

On the Mac I have tried lower resolution, grayscale, different ICC profiles, 150+ zoom, night shift, increase contrast, external monitor, nothing of that makes difference. Only difference I feel is if I'm in a dark room + low brightness + amber gunnars, then the screen gets more paper/mate look or if I'm outside but with polarized glasses. This setup made me thing that I was intolerant to glare and light...however with the chromebook non of this matters, I use it under flooroscent lights in the office without Gunnars!!!!

All computers I have tried, the text looks so flat and smooth that I can't focus my eyes on it, I struggle to focus and get daily eyes inf-lamination. Mac screen makes my eyes look more inwards the nose. iPhone X is the worst, makes my eyes want to flip.
This chrome is cheap. I feel like I can see a grid in the monitor.

I'm using browser and terminal 99% of the time, so socks5 proxy to my Mac is my work setup ATM

I yet have to research about Temporal Dithering. Any other thoughts besides it what can be the issue? Anybody else have similar problem like me?

JTL great idea!!! I'll enable developer mode and mess around.

Need to dig around to see if the opposite is possible, bootable chromium usb and test on another hardware (including Mac).

Today at work saw "ThinkCenter M700" running Win 7. This computer also seemed OK for my eyes although it was end of day and strained. Just googled it and it is using "Integrated Intel HD Graphics 530". So looks I'm fine with these integrated intel hd 4xx/5xx out of the box without any configs on chromium and win7.

Quality wise, I agree the screen is very bad quality. However I love it, to this day this is the only hw I have found without giving me any eye strain. Static picture, no shimmering whites, no vivid colors, bit greyish due to bad contrast. Very paper feel, the screen completely blends with the env, it does not feel like a light source.
I can use it at night too. My guess is you are more impacted by flicker than dithering.

Another thing I have realized I love TN panels, its not just cause of their matte finish (anti glare), but cause their worst contrast ratios too! I always set contrast to 0 and brightness to min possible (0-30).

….I don't watch TV since my issue started, I have new Samsung TV and realized besides putting it to low brightness, if I set the contrast to 0 it becomes way more tolerable. For the most part I use Nebula Capsule 2 projector, it's output almost feels like a TN monitor (pixelized and low contrast/grayish colors)
