Gaming monitors and upgrade from 24 inch to 27 give eyestrain

[Abrikoos]

Hi,

I have been trying to figure out for 2 years now whats going on and why my eye hurts (lower eyelid) with new 'gaming' monitors. I also went to multiple eye doctors and nothing is wrong with my eye. I have some dry eye but get treated for that, and dont have problems with my old monitor and work monitor. My old monitor was a 1080P, 24 inch monitor and I tried only newer 27 inch 1440P monitors.

So far I tried the following monitors:
- LG 27GP850 (Nano IPS)
- Dell G2724D (IPS)
- ASUS XG27WCS (VA)
- AOC Q27G3XMN (VA, I still own this one cause I didnt return it on time).
- ASUS TUF Gaming VG27AQM5A (IPS)
- KTC H27E6 (IPS)

I still own the Asus VG248QE (24 inch TN) which gives me 0 eye strain. Also the monitors at work (Dell U2415) give me 0 eye strain. They are a bit older, so maybe something is going on with some new tech.. I also use low brightness, f.lux, etc etc. Like I said, i have been trying to figure everything out for 2 years now..

I saw the other post which helped (viewtopic.php?t=15321).

I am looking for a high refresh rate (240hz+) 27 inch IPS monitor which i Use mainly for work (working from home) and gaming (mostly CS2). I saw some recs from Kyube and also the big page he has with recs, but I also saw the KTC H27E6 in between the list of recommended monitors which still gives me eye strain.

I want to try the M27UP now (4k, 1080p) dual mode if its something that has to do with resolution..

I am open to try out anything (except OLED cause I dont wanna have a risk of burn in, or the feeling that it might occur). Maybe a YAG monitor however the options are limited...

Can someone push me in the right direction to try out more monitors over time? It has been a long journey so far.

Thanks in advance!

All of those LCD's you've tried are KSF (PFS) WLED based displays
If you want QHD +240Hz YAG-based display (older narrow color gamut WLED backlight), get one of the following models:
The ASUS XG27AQNGV / ACER XB273UKF5 / MSI 272QRF / AOC AG276QSG2 (Pulsar panels)
The majority of other models in the QHD image res category are comprised of KSF (PFS) with seldom QD-based options, which I'll outline below as “alternatives”:
Alternatives: XQ2566X(QD TN 360Hz), MSI X30MV (QD VA 300Hz), ACER XB273UKF (QD IPS 300Hz, EU-specific), TCL 25P2A Pro (QD IPS 360Hz), TCL 27P2A Pro (QD IPS 320 Hz), Titan Army P245MS Pro / P275MS Pro (MiniLED Titan Army displays are QD-based) & a few others on the market.

In the FHD sphere, all BenQ/Zowie models are either YAG or QD-based. Other vendors, in the FHD image res category, vary between YAG & KSF/PFS, with seldom QD models (like the TCL 25G64)
The highest refresh rate YAG-based FHD model is the Zowie XL2566X+, which is the successor to the Zowie XL2566K (also YAG)
The 540/600Hz Zowie model is QD-based.
Old 360Hz GSYNC module displays (PG259QN, AG254FG, AW2521H & others) are all YAG-based.
Everything else thats ≥360Hz FHD IPS is KSF-based IIRC.

In the 4K sphere, you got the KTC M27P6, MSI E16M, AOC U27G4XM and a few others (majority of MiniLED's are QD-based). No YAG in here.

The UW segment is probably the most ridiculous one... QD-based options are as rare as it gets. The only one I know of is the old XG341C-2K
A few other ones can be seen here, most of which are not on the market anymore or haven't been released to the western market.

I am looking for a high refresh rate (240hz+) 27 inch IPS monitor which i Use mainly for work (working from home) and gaming (mostly CS2). I saw some recs from Kyube and also the big page he has with recs, but I also saw the KTC H27E6 in between the list of recommended monitors which still gives me eye strain.

I don't see where I've recommended the KTC H27E6?... It's a standard KSF-based model, nothing special about it.

Thanks for replying. I appreciate it. So you think it might be because of KSF? The dell u2415 and VG248QE are YAG and QD?

In that case I will try a YAG monitor however the ones you mentioned are Pulsar and I have an AMD (9700xt) graphics card which would make the monitor a bit expensive since they cannot use the Pulsar technology. Are there cheaper YAG panels maybe with a lower refresh rate?

And OLED also wouldn't be an option?

The alternatives you mentioned then maybe wouldn't work for me right? Cause they are KSF or why did you list those? Cause they are QD? (Sorry I'm trying to understand).

Btw the ktc h27e6 was mentioned on the rentry page.
