QDOLED 2.5Gen vs WOLED 2nd GEN - which is better for less eyestrain

[sp_00n]

Hi all, noticed this forum has a specific section for eyestrain problems so I guess it is the best place to ask.

I have a history of many monitors giving me eystrain, irritation, headache.
They were mostly VA panels. IPS worked best for me, but not all. There was one LG model I bought two for my work setup - LG 27UD59 IPS - and it was almost unusable to me. Had to replace them.

Never used an OLED for a longer time, but read a work ergonomics leaflet for scientific and IT personel of some technical university which stated that IPS and QDOLED are best for eyestrain (and eye safety in general).
Guess this only applies to 2.5Gen QD-OLED because of the subpixel layout issue that is fixed.
On the other hand, read a lot about QD-OLED headache issues.
I work using two 27" QHD IPS monitors in my office.

What I am looking for is a monitor to have at home which will be mostly used for entertainment, but also for work. Want to try the OLED path instead of an IPS as it will provide better gaming experience and I think also can be beneficial for my eyes as I limit my brighness anyway and with dark schemes most of the pixel will emmit less light when compared to an IPS ( I think).

I like crisp fonts, but on the other hand - with a 39" monitor (LG 2nd gen WOLED) 3440x1400 (my preffered resolution) I will have larger text which will end up impacting eye fatigue less (I think). VRR for work will not ba problem (I think). On the other hand there is MSI MAG 2.5gen 34" 240Hz monitor with the same resolution as LG, but different tech and less aggresive curvature (which seems more pleasant to me as I can watch something from a bigger distance being relaxed on a chair). I would go for the QD-OLED here as text would be clearer due to pixel lauout optimalizations. The latter I am not sure if it is true in fact. Also there are many "I think" notions in my post. Hence I ask.
What you guys think?
Any feedback is much appreciated.

I wrongly deducted that 34" MSI MAG 341CQPX 240Hz comes equipped with a 2.5Gen adjusted pixel layout panel from a TFTCentral YT movie where Samsung and LG OLED roadmaps are presented. His review on MSI clearly states that this model is still gen1. He also claims that text clarity is better than on a WOLED panel which intrigues me. Anyone here used both panels or WOLED and 1st gen QD-OLED?-

ASUS are releasing the PG27UCDM (4K QD-OLED 240hz) soon which has 20% less flicker which might be worth looking at (though very expensive)

too expansive for me, but thanks. Also I am leaning towards ultrawide as this purchase is not intended for work enviroment. Immersionwise UW is the way to go. I am currently testing LG 39" WOLED monitor and I am impressed by the picture quality. Seems that it is not tiring my eyes much and also PPI is not that bad... I would even say its more than OK. I would not choose that as a primary work monitor, but this is 70-80% entertainment/ 10-20% reading / 10% productivity. I am really suprised how good it is. Big problem is VRR flicker. Its really bad. Loading screens in Civ6 are killing me this is really strange due to the fact those screens being a static image. The very big advantage of that monitor is you can easily use it in a bright room. QD-OLED will not allow for that.

either forum is not very active or my issue not well researched as there are not many replies. Must admit that I am a little bit embittered as BB are mentioned often in many sites. Maybe some people with eyestrain problems can base on what I have recently tested myself.

I tried LG 39" WOLED 800R curved monitor as it was mentioned here in many places as better for well lit rooms, less fringing (worse PPI, though). At the begging I was really suprised how good this monitor is and I thought it will work for me. I was testing many setting: VRR,HDR,color temp, peak birghtness intensity, etc. As most probably I got a used monitor (someone did a swap or return to amazon) I am not sure what were my initial setting when I felt comfy with the monitor. Could not revert to them. Whatever I change, eyestrain in my weaker left eye is severe. Maybe I was tired already, but after switching back to my old VA 3440x1440 34" panel my eye immeadately felt reliefed. There can be a lot of factors impacting that strain, I am aware of that.

What is worth noting, it is that I really did not notice much fringing and PPI issue. However, with some larger text like webpages headlines or enlarged fonts - this was visible. This monitor is really good. Colours and black are gourgous.

I tried a QD-LED panel - 34" MSI - and that was a nightmare from the very start, if anyones interested.

By purchasing any OLED display, you're already forfeiting the quest of eye comfort.

They're, by design, exhibiting flicker since 2007 due to:
“the internal capacitance of the OLED driver causing a voltage ripple which shows up visually as a brightness change”
as explained here: https://ieeexplore.ieee.org/document/4347929/

LCD is still the way to go in terms of eye safety.

When it comes to LCD's, PPI plays a big role in eye comfort as well, as per https://www.sciencedirect.com/science/a ... 8216301494 where the following is stated:

“Reading from screens with high pixel densities (264 ppi or above) is recommended.”

That's 15.6" 3840x2160 or 16" 3840x2400 levels of PPI. Good luck achieving that on anything ultrawide.

You could have saved me some effort if you have written that some time ago Appreciate you found time to post here that write up. Really, thanks. Guess I have to switch to 27" 4K IPS at work.

edit:
btw. I could not stand VRR. Had to stick to 240Hz. Brightness changes were extreme on that LG. Its unusable. I cannot figure out how people can even use that monitor with the feature enabled.

edit2:
wonder why OLED TV is not that much tiring to an eye.

I'd even suggest trying to grab a 27" 5k iMac or a alternative of similar specs with higher refresh rate. I think a panel 32" 5k 144hz panel has been announced.

Refer to this page for more information on PPD & PPI: https://phrogz.net/tmp/ScreenDensityCalculator.html


VRR is somewhat of a band-aid anyways. It is sufficient for most to cap in a multiple of the refresh rate to make the tearline static. For example, on a 240hz display: 60fps, 120fps, 240fps...

Distance plays a role in flicker perception. The further away a target is, the milder the perceived flicker is.
How this scales exactly is beyond me.

I currently use DELL S2725QS which is 4K IPS w/ 1300 contrast ratio and 120Hz refresh rate. Seems to work for me.
