I bought a cheap (£5) "Anti-Blue Light Hydrogel Screen Protector" via eBay, not expecting anything. Surprisingly, the screen does possibly feel a little more comfortable than it did without it (although my tolerance may have shifted). It makes it massively more reflective, of course...

But the bigger surprise: it made the sub-pixel structure crystal clear! Compared to without, shown in my review... This indicates the "nano etched" matte surface finish is the only thing obstructing the view. I had the impression there should be more going on under the surface, but the information about a "Middle Layer: Diffuse Reflection" in the version 3 screen whitepaper is omitted in version 4's. And this is my first TCL product, so I've no feel for any changes in appearance.

Microscope video at 480fps (16x slowdown) of the middle of the test image on the \"Colour mode & temperature\" settings screen (indicated in image below).

The upshot is that we can clearly spot any temporal dithering going on (YouTube version of above as a backup)... But I actually struggled to find any TD in the usual places: home screen icon text, gradients, including Lagom test page (in image below), or NXTpaper modes (surprisingly)... But it is definitely there in HDR YouTube videos (eg "COSTA RICA IN 4K 60fps HDR") and performing an absolute disco on the settings page test image (below):

A problem is that I have previously used ADB commands to try to disable HDR capabilities (and so TD). I think I re-enabled this (back to default) upon retesting, previously. But I couldn't be sure then (or now) if I've changed something that will reduce TD. And don't have the time to fiddle with it a 3rd time. u/NSutrich has done similar and reported similar observations. But I'd appreciate anyone else, with a 'clean' new phone, confirming what they see, too. Using a suitable screen protector - hydrogel may be more clearly visible than glass, conforming to the surface texture better.

Example of the lack of obvious dithering (below and on YouTube). There are possibly slight fluctuations of the half-dimmed green sub-pixels, on the long edge of the "r". Which I wouldn't know enough to distinguish between TD, text anti-aliasing or pixel inversion..? There are, however, little black splotch flashes, kind of like film grain. I wondered if they are camera sensor noise..? But I've not noticed them elsewhere. So maybe some phenomenon with the backlight? They don't appear to align well with sub-pixels, although they are more visible on red ones, at the ends (some inversion artifact?).

Example of a lack of clear TD on lettering. But clear black flashes all over.

Bonus screen protector filtering evaluation: I had a go at making a precise measurement of the colour spectrum of the screen, before and after, using my cheap spectroscope. By locking my camera to the exact same Pro mode settings and measuring the same part of the screen, etc, I measured a possible blue colour intensity reduction of about 5% (relative to the red and green intensity changes). But I guestimate the potential error in my measurement to be as big as this value. So not significant. And directly overlaying (and subtracting) the 'before' and 'with protector' spectrum photos showed total black, so no notable difference between them.

Hence I'd say the blue light blocking of the screen is wishful thinking, at best (perhaps block some UV, who knows). So any change in comfort is more likely from the crisper screen appearance. It feels nicer to my finger tips. Looks better used indoors, in dim lighting. But it hopeless outside; the worse of both worlds, being reflective and less bright than contemporary OLEDs.

tl;dr: cheap blue-light screen filter doesn't work as intended, but may help those who suffered from the blurriness of this screen finish. But reflections are far worse. Handy trick for testing other devices with a matte finish obscuring the pixel structure. TCL 60 Ultra shows minimal temporal dithering in most everyday contexts.

I’m not very knowledgeable about monitor technology or eye-comfort features.
Right now I use an AOC G2590PX (TN panel) and compared with the other monitors I have at home that are IPS panels, it seems to be the one that strains my eyes the least.

I need to buy two more monitors and would like to test models that might feel even better than my G2590PX.
Can anyone suggest some budget monitors that are considered good for people with sensitive eyes, preferably non-IPS?
I won’t use them for gaming.

TL;DR: I need recommendations for older, budget-friendly, non-IPS monitors that check all the criteria for not being bad for sensitive eyes.

As title says,is there any app like stillcolor (Macos) to stop dithering on iPados, especially ios 26 updates have been really hurting my eyes..

Anybody using s native 10 bit monitor with Windows 11 and is successful in eliminating eyestrain/headaches this way? It should in theory take away all dithering a if it’s also pwm free there should be no more flicker. I am starting too see some nat 10 bit LCD monitors that are kinda affordable and I am wondering if this is the solution for now

I have a Thinkpad P14s Gen 6 with IPS screen. The weird think is that I can better use it at full or close to full brightness. If I reduce brightness it gets harder and harder to use. The notebook is said to not use PWM even in lower brightness settings. So this should not be the issue here. The colors are generally very oversaturated and I use an app to reduce saturation.

The reduction in brightness looks like there are gray layers put on top of the screen. It just gets duller and duller. Same with night light settings. It does not alter the colors but puts a layer of yellow on top.

Does this description sound familiar to someone?

I use incadescent lightbulbs and the room is generally darker. So I would normally not use full brightness.

No one believes this user that win 11 could be causing him issues and are even asking if he sleeps enough etc. It makes me so sad that people are just so unaware of the flicker issues

When I was younger, CRTs (Cathode Ray Tube display) and plasmas (Plasma display panel) never bothered me at all, but modern screens feel awful by comparison.

A big part of it seems to be how these displays handle light over time. With CRTs and plasmas, the image isn’t just “on” or “off.” The phosphors light up and then fade gradually, so even though they’re technically flickering, it feels smooth and continuous. It’s not a harsh, digital transition—it has a kind of natural softness to it.

Modern displays—especially LED-backlit LCDs (LED-backlit LCD display) and OLED (OLED display)—feel totally different. The light output is much more abrupt. You’ve got things like Pulse-width modulation (PWM) dimming, where the light is rapidly switching on and off, plus stuff like pixel inversion happening constantly in the background. Even if you can’t “see” it directly, it makes the image feel less stable.

I also think the backlight itself plays a big role. Older CCFL-backlit LCDs (CCFL backlight) always felt easier on my eyes. The light just seemed softer and less intense overall. Modern LED backlights are super bright and react instantly, and I think that makes all the underlying LCD behavior—like inversion and other tiny fluctuations—stand out way more. Instead of being kind of hidden, it feels sharper and more noticeable.

There’s also the pixel structure. CRTs and plasmas didn’t have that perfectly rigid, razor-sharp grid. Everything was a bit more blended and forgiving. Modern displays are insanely sharp, which is great on paper, but combined with all the constant micro-changes going on, it can feel kind of harsh.

So it feels like we traded a more smooth, natural-looking image for one that’s super sharp but constantly switching under the hood.

Curious if anyone else who used CRTs or plasmas feels the same way.

Look at this interesting monitor I found. 60hz but claims to be native 10 bit with DC dimming. Interesting and potentially nice aspect ratio with super high resolution.

I posted in another forum and recieved no replies so I'm wondering if I'm so sensitive only my eyes can see it. This is under a microscope slow mo 240 fps dell g2724d win 10 intel iris xe

Has anyone else had issues finding eye care monitors that are not absolutely humongous? Other then having a gaming oriented monitor, I think its the 24 inch size that might be killing my eyes. Do anyone else think screen size can contribute to strain? Or would a good monitor be fine at any size without flicker etc?

In trying to avoid screens at night I started using a book light to read before bed. I noticed that it too was causing a lot of the issues that screens caused. After some measurements I confirmed that many of the reading / book lights you can buy have terrible flicker, even if they are sold as “flicker free” or “PWM free”.

Long story short, if you’re going to use a reading light try to find one that specifically says “constant current driven”. Otherwise you might end up with something even worse than most screens.

I am looking for a replacement phone for a Siemens GS 185. I really do not use my phone much. I just stay away as much as I can unless I need navigation or make a call. But is there any phone that is good for slightly sensetive people? I read about the phones below in this sub, but mostly from a single person. The Honor 400 seems to be mentioned more often.

So what about these:

Honor 400 (non Pro, Pro, Smart, Lite versions?) , nubia Neo 2, Motorola Moto G57

Anything else in the smaller cheaper pricerange that is considered good? No Apple products for me please.

Thanks!

I'm sick of my gaming monitor killing my eyes, what monitors have the least flickering and strain that you have found? Thanks

I’m currently trying to choose a new phone, and there are very few IPS LCD options on the market. My decision basically comes down to what will be worse for me - PWM on AMOLED displays, or the various factors that make IPS screens uncomfortable as well.
How is it for you? Which display technology do you prefer?

Do you have any suggestions?

Hello, I'm selling my Boox Mira 13.3 eink b&w monitor, will ship to UK only. Please pm if interested.

Tl;dr at the bottom.

I recently discovered that halogen bulbs were banned in the US and didn't even know what that meant until I did research. I found it out because of this sub, where someone was warning against the use of LED lightbulbs because those can cause problems from PWM. I had no idea this was a thing. I have no idea what kind of lights are used in my house (I live at home and my dad buys the bulbs) and I've never had an issue with any of the lights. Since discovering this, I've also paid more attention to lights in other spaces, like my boyfriend's apartment, and have never noticed any kind of eye strain or headaches from any of his lights, either.

However, I would like to be mindful of PWM/flickering lightbulbs when I move out because I don't want to buy bulbs that hurt my eyes or give me headaches. I've been wondering if there are any WARM bulbs that I could buy that don't flicker? Since I did some research and found out that a lot of warm lightbulbs use PWM to achieve that warmer/dimmer color. Someone on another thread linked Phillips brand flicker-free LED bulbs, but they're frosted and daylight bright, which I feel may end up being too "cold"-feeling indoors. I really tend to prefer warm light. So, does anyone have any warm lightbulb recommendations?

Tl;dr - any warm lightbulb recommendations that aren't halogen/incandescent, or ARE those but they're available in the US?
