It is a new panel, manufactured around the end of 2023. Laptop is from end of 2024. I'm using linux, with AMD graphics driver. The same laptop that works with my eyes, when connected to an external monitor, causes eye strain.
After researching the topic a bit, i'm thinking it might be the NanoIPS or QuantumDot technology that causes issues for me. My laptop screen is neither, and i have zero issues with it. All the latest monitors seem to use NanoIPS/QuantumDot, when:
- High refresh rate
- High DCI-P3
- High sRGB (over 100% seems to be always NanoIPS/IPS Black/QuantumDot)
- Very low pixel response time
I've found some monitors without NanoIPS and ordered them:
- Dell S2722QC
- LG 27GR93U-B
Other monitors i found without NanoIPS (at least i think):
- Gigabyte M27U
- INNOCN 27M2V
- LG 27UP850N-W (BOE MV270QUM-N51)
- LG 27UQ850V-W (BOE ME270QUM-N20)
- Asus PA279CRV (AUO M270QAN06.5)
Panels with 60Hz refresh rate and response times of around 4-5ms seems to be mostly normal IPS, not NanoIPS.

The first NanoIPS panels were manufactured 2018 by LG, so it might be in your case that NanoIPS could also be a possible reason for your eye issues.
