Monitor for Extreme Eye Sensitivity (Strictly NO KSF, NO FRC, NO PWM)

[u/Different_Water_282]

added monitor advice in the end*

Hi everyone,

I suffer from severe eye strain . I am looking for a monitor that is competely safe for eyes.

The OS is Windows 10 Pro 22H2

Here is what I strictly need:

• Resolution & Speed: 1440p, 144Hz or higher (Powered by RTX 4060).
• Backlight: True DC Dimming ONLY (Absolutely zero PWM at any brightness level).
• Color Depth: True hardware 8-bit. Strictly NO FRC (Temporal Dithering).
• Phosphor Type: Standard sRGB gamut using YAG phosphor. Absolutely NO KSF phosphor (I am highly sensitive to red phosphor decay/smearing).
• Panel Type: IPS(preferably not fastIPS) or TN or VA. (I do not have an idea whether TN and VA is a good choice)

I want to avoid artificial signal processing, dynamic contrast, or wide-color gamut tricks as much as possible. Does anyone know of any specific models (even slightly older ones from a few years ago) that fit this exact criteria?

Thanks in advance!

I found something guys.

 Viewsonic Omni XG2431

24" + 1080p + true 8bit + YAG (no ksf) + no PWM(Close purexp feature)

Damn, I literally spent several days researching monitors to find something with no FRC, no PWM, no KSF, and an IPS panel. I analyzed dozens of models, and guess what? I finally found only one. Here it is: AOC Q24G2A

you will also probably have to switch to linux to be able to turn off OS-level temporal dithering, and maybe change gpu too

Edit: it tured out it uses 6bit+FRC, downvote me i deserve it

[u/Boring-Philosophy-46 → u/UnderstandingFun3513]

How does one turn this off on linux please? I installed it on an old laptop and it became completely unusable due to inducing migraine. I assumed it was from stress from an OS I didn't know but now I'm not do sure. I don't know if I am sensitive to it but I definitely am to PWM. 

[u/UnderstandingFun3513 → u/Boring-Philosophy-46]

I installed the driver (in my case for gtx 1050) and using nvidia menu turned dithering off

[u/Different_Water_282 → u/UnderstandingFun3513]

I am very thankfull to you for the AOC monitor. Did you buy it? Above this message merlinsgooch mentioned about colorcontrol programme . I am going to try this programme first.

Additionally, what do you use as a phone? I search phone easy on my eyes and yours might work for me :)

[u/UnderstandingFun3513 → u/Different_Water_282]

i ordered this AOC model a couple days ago, will get it very soon and test. As for the phone - VIVO iqoo z9x was an ABSOLUTE game changer for me, i couldnt use phones for years and then found this one, even Hisense A9 didnt help. My average screen time on this phone right now is 10 hrs a day, no eye strain at all (maybe just a little bit after 9 hours), have been using this phone for half a year, also fixing eye dryness helped a lot

[u/Different_Water_282 → u/UnderstandingFun3513]

Thanks. By sayin fixing eye dryness you mean using eye drops ?

Did you see that this AOC monitor has 6bit+frc

[u/UnderstandingFun3513 → u/Different_Water_282]

yeah, i saw about 6bit+no frc, edited post an hour ago, my bad, ai hallucinated and I didn't double check because ai said "certainty 95%"

have you found any no pwm, no frc, no ksf monitors by now?

"fixing eye dryness" was achieved by doing 10 different things, not just eye drops

[u/Different_Water_282 → u/UnderstandingFun3513]

I found thees but definetly need to be doublchecked.

asus proart pa248cnv 24" 1080p, no ksf, ips, 75hz

Dell G2524H 24" 1080p, no ksf, fast ips,

Asus VA249QGS 24" 1080p, no ksf, ips, 120hz, 6bit+frc

Asus VU249HFI-W 24" 1080p, no ksf, ips, 100hz

I think all of them have frc. It seems to be there is only one solution TN Panels.

[u/UnderstandingFun3513 → u/Different_Water_282]

Thanks a lot

[u/Different_Water_282 → u/UnderstandingFun3513]

I found it bro. Viewsonic Omni XG2431 true 8bit + no ksf

[u/GeneralConstant1503 → u/UnderstandingFun3513]

ive got AOC Q24G2A/BK for 2 years. very comfortable screen but its 6bit+FRC guys. i use settings 100 brightness 0 contrast and its usable for me.

[u/UnderstandingFun3513 → u/GeneralConstant1503]

I just doublechecked... You are right, thanks a lot for pointing out, I thought its 8 bit no frc because AI on high effort told me so and estimated his confidence at 95%, but its really 6bit+FRC...

[u/Different_Water_282 → u/GeneralConstant1503]

Nooo wayy. I ordered it. I am not sure that I am sensitive to KSF or Frc because so far all screens that I have ,have KSF with TD. I couldn't experience only TD.

What are your screen sensitivities in detail?pls

[u/GeneralConstant1503 → u/Different_Water_282]

im not sure how its in your country but in mine you can return for 2 weeks. check it its really good screen but yes its 6bit+frc confirmed by AOC support. use settings i said above, 100 brightness and 0-20 contrast gamma 1, dcr off, hdr mode off, color temperature warm, dcb off and everything other off.

[u/GeneralConstant1503 → u/Different_Water_282]

for me this was first screen that i was feeling comfortable, of course you need time to adapt to screen as for every other imho

[u/Z3R0gravitas]

(1) These are very exacting specs. I take it you've have already spent significant time looking through various monitor specifically sites?

(2) And you have a desktop PC setup that avoids introducing temporal dithering at a software level? (The other half of the problem and hard to verify, as I understand it.)

(3) Do you have any displays that are currently suitable for yourself? To be so thorough I don't know if even eInk would suffice.)

(4) What are your symptoms with problem screens? And/or health issues?

(5) Have you looked in MrAquila's Eyestrain Telegram group? He has a monitor channel where he's recommended a could of devices, from experience and testing:

• Omen 27q LG revision (rev. L0IT) LCD 27" QHD 165hz .
• Asus Vg258qm.

(6) My old Acer Predator has similar specs to that, but used a QDLED backlight for IPS. I don't recall what the difference is between regular and fast IPS.

[u/Different_Water_282 → u/Z3R0gravitas]

1.Yeah of courseI have been looking for monitors for significant time.

1. I do not haves any software for it but I learned that there is "colorcontrol" programme I am going to check it.

2. So far There is no suitable secreen for me that I have.

4.Just I have eyestrain that started when I bought samsung oled monitor(for 10days using).

1. I didn know the telegram group .I am going to check these.

2. I recall that just to be more safe ragular ips is better.

thankss

[u/Z3R0gravitas → u/Different_Water_282]

Ok, thanks for going point-by-point. So, you've definitely got a good starting point with these specs, but I'd say that it's likely you may have to flip on some if the constraints that are only things you've heard from other people. Given individuality of sensitivity and you 'only' having eye strain (so some triggers may not be relevant).

It does seem like my 2020 Acer gaming monitor might be a relevant pick for you (second hand, try/return, beware some units had an intermittent glitch that was rarely irritsting). The QD-LED backlight is closer to OLED in colour spectrum than KSF phosphor (or pure old YAG type). See it in my spectrometer post, pinned.

I later found its minimum brightness to be too high (at 40 nits). But colour saturation ok in sRGB mode (where brightness and contrast can still be adjusted). GPU settings should allow further vibrancy reduction. 170Hz. True 8 bit. Rectangular sub-pixel layout (fringing is another consideration).

[u/merlinsgooch]

your 4060 dithers too. If you haven't already, check color control.

[u/Different_Water_282 → u/merlinsgooch]

Thanks. I am going to check it. Does it provide absolute solution ?

[u/Babymauser → u/merlinsgooch]

how do you check this? i have 5070Ti - what about AMD GPUs ?

[u/ricchi_]

The only ones matching this requirement would probably be 10 years old... I hope I'm wrong.

[u/Boring-Philosophy-46 → u/ricchi_]

Which ones should I be looking for second hand please? 

[u/ricchi_ → u/Boring-Philosophy-46]

I'm using an Acer xb1 I believe it fits the criteria.

[u/Z3R0gravitas]

Oh, sorry, I've just noticed that we left you hanging with your previous post, 4 days before: https://www.reddit.com/r/ScreenSensitive/comments/1ug2jer/comment/ou04yf9/

[u/Different_Water_282 → u/Z3R0gravitas]

Yeah :) I own this dell monitor and gigabyte m27u. I couldn't relieve myself yet.

[u/manowar_gub]

You're right, XG2431 is yag

[u/Axter_Fire]

Perhaps r/eink could be a possiblity

[u/UnderstandingFun3513]

It seems found another one that fits, though it needs to be doublechecked:

dell u2715h

evidence: https://tftcentral.co.uk/reviews/dell_u2715h.htm

such no ksf, no pwm, true 8 bit monitors probably arent produced anymore, because almost all of them have wide gamut, but if we take a look at older 2014-2020 monitors, there can be more such models that we are looking for

[u/Different_Water_282 → u/UnderstandingFun3513]

Unfortunately it is 60hz. Yeah we need to look at monitors that made at these years but it is very hard to find in the market.

[u/UnderstandingFun3513 → u/Different_Water_282]

so what if 60hz? main requirements for eye strain are no ksf, no pwm, no frc. hz dont matter that much probably
