All,
I have been a follower of this forum and a long time sufferer from LED lighting.
My symptoms are different to most that are on here. Laptop and monitor screens make the left side of my face twitch which makes me feel dizzy. I've had this condition since 2004. I found a laptop that worked for me a few years back Thinkpad P51 but it was getting old and I recently went through 10 laptops until I found one combination that worked. I wanted to share it here in case it helps someone else.
I found the Thinkpad P1 Gen 4 works provided it was UHD resolution and I set it to 200%. The same laptop at the 2000x1500 resolution did not work, and any zoom of 150 or 125 did not work either.
In addition to using this particular laptop, I still have to use night light and ditherig but at least it works.
Happy to discuss more or answer questions from others that have a similar condition from displays - face twitching leading to confusion and dizziness.
