He's also got Cleartype on and set to RGB stripe even though the OLED is not RGB stripe (though to be fair, Windows doesn't really make it clear what each page of the ClearType tuner does).
But yeah, if you use a _tiny_ font and sit _really_ close to the screen, you see fringing. In practice for me, it's been unnoticeable.
At one point in time 95%+ of HN comments were cheering on about Atom the text editor and later VSCode as being fast enough or unnoticeable. When Sublime user are baffled as to why. And Sublime isn't the fastest text editor either before Zed came out.
Yes, 10 times out of 10 I could tell an OLED font rendering to LCD. I wish I couldn't. Some people call it taste, some call it absurd requirement.
I could go on and on. The point is most people aren't very picky and picky is a definition defined by average. But there are those of us who have, let say very high standards that cares about PPI, Refresh Rate, Colour accuracy etc. Keyboard Key's typing distance, trackpad responsiveness, all the tiny details that I wish I could unseen and un-feel.
As the article state, RGB OLED Tandem is coming out, and I cant wait to see it in person. I have been pro LCD on Laptop for so long that when I learned Apple will soon ditch LCD for OLED I was worried. Hopefully the new sub pixel layout will fix it.
I'm sure I would notice and be annoyed by this fringing too unless the pixels were so small I really couldn't see them. Probably needs to be slightly higher than 200 then. But I haven't seen oled monitors with such high DPIs. The highest I've seen is 4K on 27" which wouldn't even do for me on LCD.
I can see the difference between 60Hz and 120Hz on phone screens, and I think it's worth the impact on battery life.
I can see the difference in speed between VSCode and editors like Sublime or Zed, however in this case I prefer the additional features at the cost of speed/smoothness.
After asking the owner of said screen how he could stand that... "stand what?"
Yep, I guess most people are not that picky.
I second this. I can tell, and I would never wish that ability on my worst enemy. Very glad there's a (slim, but exists) market catering to that — and that I no longer have to buy a monitor that costs as much as a small motorcycle to not be constantly infuriated at everything in my field of vision when working.
I kind of want to see one of the Atom vs Sublime people use that for a hot minute.
At home I upgraded from 60hz to 165hz and was underwhelmed. I see the difference .. but eh.
I doubt it's Cleartype, the close up photo of the U3223QE show all subpixels uniformly dimmed on the fringes. The post also says the monitor is attached to a Mac mini and a previous post about OpenSCAD has a screenshot with MacOS window decorations.
Had I been using this on Windows I would have started to solve it by trying to tune that.
You act like being able to see this a minority opinion, it’s not, and it’s a known issue. And you don’t need to be sitting close, or using a tiny font to notice it.
My 4K OLED is noticeably less clear compared to an IPS display and I’d never use it for productivity as a result, because why would I willingly subject myself to an objectively worse experience?
Then as I went back to where he was describing the problem ("fringing"), I kept forgetting when I scrolled back to the images which was which (and which image was supposed to be "worse").
I'm on a 2025 Macbook, so maybe the laptop's monitor masks the issue?
There's no Cleartype in use here, as the first paragraph says, it's macOS.
And I'm using the default font sizes because they work well for me on an LCD. The point of this post is to document my experience with trying a current-gen generally-available OLED and how it did not work out well because of the subpixel arrangement.
It's also not just an issue on text, it affects any high contrast edges, especially perfectly vertical or horizontal ones. This meant that CAD stuff, spreadsheets (the grid), and large colored sections in graphic design software looked off as well.
There is no Cleartype; this is macOS. And as mentioned I couldn't see the fringing from normal use, that only became evident with macro photos. During normal use it just looked sparkly or weird or artifacted.
And yes, the fonts are small, but that default size in VS Code or Numbers.app -- the example photos -- work well for me. And look fine on an LCD.
I got unbearable eye strain from it, even though I use rather large fonts, and the ppd was the same as with my previous IPS. Yes, the “more fuzzy” text was very much noticeable too.
Maybe it varies by person, maybe it’s influenced by things like astigmatism, but I totally see where the author is coming from, and I too am waiting for the new OLED panels to see if there’s an improvement.
I do have astigmatism. You do make me wonder if this plays a part as well...
Also, many people can see and are bothered by particular non-rectangular pixel layouts - it doesn't require doing odd things.
The sub pixel geometry on samsung's qd-oled needs very specific font configuration to be correctly displayed, and even then it just stops looking bad.
And no, no Cleartype here because (as mentioned in the first paragraph) it's a Mac running macOS.
You have to understand there's enormous effort that needs to go into this to make things look good. It's absolutely no surprise to me that Jobs era Apple used to stick to integer scaling ratios with relatively low-res phones while the competition battled with paper specs.
The trick to make things look good is to be mindful of the pixel grid, (and the subpixel layout). You have to choose font spacing and fonts so that major font features line up with the pixel grid. You sometimes have to slide a letter a bit to the left or right, which might result in inconsistent spacing, you might even want to have multiple versions of characters to hide these issues.
This applies to borders as well (both spacing and thickness).
Sometimes you can't make it look good no matter what you try - and the designer has to change it.
While flexbox and other super-duper layout algorithms might be very clever, if you use them, there's no way to line things up perfectly, and if you expect to, you might be in a world of hurt.
Adding PPI is a poor way to fix this. Even if you 2x the resolution, going from 1080p, to 4K, these issues still persist, and you quickly run out of hardware beyond that.
There's no wonder why modern 'flat' UIs usually have 1-2 pixel-ish gradients on edges of features, or use smooth transitions, it's a cop out - but that's the only thing that works with flexible layout, different pixel densities. But subtly, you notice things looking a bit blurry, just as if the images were low-res, even though the pixel density is insane.
ClearType is brilliant, but it only works with a certain set of assumptions, like a bit of light bleed (which exists on LCD but not on OLED afaik), and needs to know the subpixel layout, and can result in absolutely gorgeous looking fonts with relatively low res displays.
There's a reason why Windows 95-era UIs have a cult following - it's insane how sharp they looked even on hardware that on paper is much worse than modern stuff.
Windows?
Yes there is color fringing if I take a zoomed in picture with my camera, but nothing I notice in day to day use. And I've been highly annoyed by missing or bad ClearType rendering.
I specifically went for the 27" to get the extra pixel density though. I might not have been happy with the 32" variant.
That said, the true blacks and bright whites is something else. For me a very significant upgrade both on the desktop and in games, despite the previous being an upper-level LCD when I bought it 4-5 years ago.
If I had to guess it could be something in the manufacturing process is more difficult.
It will take so long for burn in that you probably want to buy something new anyway.
My LG OLED 4k tv is by far the best picture I ever had.
My Samsung 4k 27" gaming OLED is beautiful when gaming too
I can't imagine how annoying it would be to watch a movie or play a game and see something burnt into the white parts of what I'm supposed to be looking at.
I don't want to be purchasing a new gaming monitor every two years.
The display the author doesn't like is a specific model Dell QD-OLED with a sub pixel arrangement that causes a fringe above / below text.
There are macro screenshots that reveal the sub pixel details of a preferred LCD compared the disliked Dell OLED, and it's easy to agree with the author's discontentment.
But the categorical complaint about "OLED" is an over generalization.
Treat the report as a warning to investigate the sub pixel characteristics of any monitor you may be considering.
While the author's complaint is perfectly valid, in practice the advantages of even current OLEDs - for me - far outweigh any disadvantages due to subpixel layout fringing and everything else. Even for programming, the lack of backlight and resulting infinite contrast makes such a huge difference in my day to day life that I refuse to use a non-OLED monitor anymore for any purpose whatsoever. Heck it could be half the DPI and I'd still go for OLED anytime.
The only reason LCDs still exist is price, nothing else.
It’s in fact most, if not all of the PC display OLEDs on the market today because they almost all use non standard subpixel arrangements, but will change soon with the introduction of newer generation panels.
> But the categorical complaint about "OLED" is an over generalization
It’s really not, given again we are talking about the majority of PC OLEDs in production today having subpixel layouts that cause issues for users with text rendering.
The screen shown in this blog looks like it's ~140 PPI. Sure these screens are cheap, but they're best used for moving graphical content.
In the demonstration image the text is just 9 pixels tall, while thatis legible, it is unacceptable for long term reading and is completely reliant on subpixel rendering to produce an impression of smoothness.
Now, I spent an amount of my work life staring at a company-issued 27 inch 1080p display, and that was absolutely horrible, but with 4K, I'm not sure if I would even be able to see the improvement if I went to 6K or 8K even, which I always thought was mostly useless outside of gigantic television sets. Is it really worth it? Can you really genuinely see the text blurring on a 4K monitor?
If you're not using text around 9 pixels tall, as in the article, you're probably going to be okay. On a 27 inch screen at a typical office screen distance, I'd probably want 6k, but 4k is pretty good and 1080p is terrible.
The other issue is that it's not just a text problem. It affects any high color contrast edges, especially directly vertical or horizontal ones. So subpixel rendering tweaks for text rendering (eg: Cleartype) don't solve the whole problem.
Only Microsoft can fix it, and as far as I know, they don't seem interested.

I use MacType and it works really well. You can tune many more things than with ClearType.
Meanwhile I’ve got an MSI OLED 32” 240Hz @ 4k monitor which was super expensive but is absolutely incredible. It takes getting used to a monitor that performs a maintenance routine on itself any time you leave it active for more than a few hours. But it’s great for work (with some aggressive zoom levels) and gaming (with some aggressive black point levels).
Are you saying this is a con as it sounds like a pro to me.
Off topic, but JFYI, with last year's firmware update (OLED CARE 2.0), you can now delay the refresh notification for up to 24 hours. I haven't seen the notification pop up since updating.
The article also compares a budget display Dell S (OLED) vs higher end Dell U.
I've moved back to using a pair of 4K LCDs that I had, and honestly the resolution and aspect ratio are better for text and programming anyhow.
My PC monitors are my only remaining LCD screens largely due to the text fringing issues mentioned in this article and bezel size.
When the OS assumes correctly what the monitor actually looks like, you get even better text rendering. When it guesses wrong you get a horrible mess.
LCD can have a uniform layout because it's a passive layer doing the filtering. In OLED, each pixel is active and that blue one is trying to burn itself out much faster than the other two.
Must say my first generation Samsung display looks amazing both for gaming and programming though. If it wasn’t for the annoying smart-tv stuff, and the mini connectors, it’s a perfect monitor.
There are three upcoming monitors that take advantage of this new Samsung ultrawide 360Hz V-Stripe QD-OLED monitor- the Asus ROG Swift PG34WCDN, MSI 341CQR X36, and the Gigabyte MO34WQC36. They are all roughly on-par, with the exception of MSI, who cheaped out on their DisplayPort 1.2a specification (UHBR13.5 instead of UHBR20) requiring the use of DSC to drive the 3440x1440 resolution at the full native refresh rate of 360Hz.
I have decided it is time to update my aging Asus PG348 34" Ultrawide (which has been one of the best monitors I've ever owned, and served me very well) - and will be replacing it with the PG34WCDN as soon as it is available.
The actual Samsung panel being used by these three monitors: https://www.samsungdisplay.com/eng/media/news/detail/ssdsNew...
> Within the past few weeks LG has announced RGB stripe OLED panels which will resolve this problem, but there aren’t currently any monitors available using these panels
with two links to five known upcoming devices.

3440x1440 @ 34" (110ppi): Asus PG34WCDN, Asus XG34WCDMS, MSI MEG X, MSI MPG 341CQR X36
Digging into this further, I also found another Asus panel that's closer, if not all the way there yet (5K would be, but this is 4K) to the usual Mac pixel densities:
3840x2160 @ 27" (163ppi): Asus PG27UCWM
I'll still be waiting for 5K @ 27" with the new tech, but I'm really glad to see they finally solved this!
I actually am using it, but I didn't want to go down the rabbithole of an all-encompassing article on displays, PPI, scaling, etc. Using it to scale the display really helps, but I find that for the size of things I like 3008x1692 (on a native 3840x2160 panel) and this looks fine on an LCD. And is better than native res on the OLED, but still not great. It still bugged my eyes.
I just went with native res for demoing things because it's a worst-case, but the fringing problem, because it affects all strong-contrast edges not just text. It was also really noticeable at thin/narrow lines such as when doing CAD or between cells in spreadsheets.
These monitors are great when scaled but have real issues rendering text and other fine details at their native resolution.
ms cleartype isn’t always compatible with oled.
The OP seems to have a problem not only with fonts but also with straight lines in CAD.
He bought a factory defective monitor. LCDs like this exist, Samsung sold them as AMOLEDS called Pentile. They are hideous.
Until subpixel is eradicated from existence, we shall continue to suffer this.
The problem is such:
1) Windows exists.
2) Windows invented Cleartype for Vista, it was ugly and fringed hard because they misunderstood human perception, the sRGB standard, and math.
3) Windows then readjusted Cleartype for DirectWrite. OSX before Retina and Freetype use subpixel tuning also compatible with human perception, sRGB, and math.
4) Many applications on Windows do not know how to ask Windows what the subpixel orientation is; either they assume RGB all the time (do not do this!) or they only read the first monitor (do not do this!). Windows can tell you per monitor, this is the only correct way. This API has existed since Vista.
5) This problem also effects DPI: they either cannot scale or only scale for the first monitor. Windows scaling for you causes _exceptionally bad_ color fringing for subpixel rendering. Again, the API for that has existed since Vista.
6) Many monitors do not list their subpixel orientation in their EDID. Ones that do and also are rotation sensitive do not set their EDID for RGB->VRGB->BGR->VBGR as you rotate them. Windows assumes RGB for any monitor missing that EDID field.
7) Windows only knows (V)RGB and (V)BGR. It does not know W+RGB, it doesn't know any sort of complex multi-row arrangement (such as Pentile).
8) Many applications ignore your Cleartype settings in Windows, and use RGB at default color weights no matter what you do, even if you turn subpixel off and do greyscale only.
9) And the worst sin of all: people embed screenshots in their documentation and websites, and they never update them. The Internet is full of Vista-era fringe-filled Cleartype text. This ties into 5, but is worth mentioning as its own.
Edit: On second reading, the author says they're on a Mac. Macs don't have subpixel rendering anymore. I don't understand the author's complaint, they have greyscale and avoid all these problems.
I will bitch about Apple's mistakes over the past decade, but removing subpixel rendering from their ecosystem was a smart move: makes all their text rendering compatible with all future monitors forever, and moving to HiDPI eliminates the need for it anyways.
With DirectWrite and Freetype, subpixel rendering isn't done for colored rendering. On OSX, due to lack of subpixel with Core Text, it also isn't done.
I suspect what you're really asking is "why does high color contrast look weird at the edges?" Because some monitors are "exceptionally clear and sharp", and people have been selecting monitors for this trait for over a decade.
On LCDs, "good" polarizers make it hard to make out individual subpixels (which also makes subpixel rendering kinda moot on them; you'll see the fringing but the text won't look any sharper than greyscale, and noticeably less sharper than aliased); instead of "clear and sharp" they're more "natural".
OLEDs and MicroLEDs do not have polarizers, and they're the sharpest monitors I've ever seen. However, good news (at least for me): I can see subpixels on a 1080p 24" during high color contrast (ie, fringing fonts), I _cannot_ see them on a 4k 24".
Even if I integer-scaled 1080p to 4k, I would be using an array that looks like...
R G B R G B
R G B R G B
.. to represent pixels. I can't see subpixels during situations like this. So, the only way to avoid the problem is just use HiDPI monitors. 32" 4k seems to be a very common size for Mac users; it causes it to do Retina scaling correctly, while also being about 150% the DPI of a 24" 1080p, or about 125% of the DPI of a 27" 1440p (the two most common sizes).
My recommendation also is: never use below 4k on OSX. OSX's handling of sub-4k monitors is broken, and usually leads to in-compositor scaling instead of letting apps natively render at LoDPI.
I begin to feel like we may need the equivalent of what audio shops used to have: a listening room with normal furniture and a big switch to test different things, but for eyes not ears.
I only buy s/h Dell monitors 3-5 years behind bleeding edge because I am a cheapskate with old eyes, who can't see past the dust on my glasses anyway. But I genuinely can relate to this problem. It would suck to invest in the best you can afford and find it's not doing what the dollars expect for you.
It doesn’t even need this. The old way of buying stuff was from a shop. With big ticket items you build a relationship with staff and their recommendations helped. Now it’s all shipped or bought from faceless big box stores.
I know it's the panel, because I have an office BenQ 21 inch with technology called sth like EyeCare on the side as the second monitor. Compared to the gaming one - it's a balm on my eyes. Sometimes I'd put a document or LLM window there even when the main screen is empty, just because of how nice it feels on the eyes.
Except for few situations where the poor man's HDR does help me see more details in the dark (small edge in multiplayer), I believe that I would be better off with a monitor engineered for office work.
Think about it, I got lured by all the gaming hype, but what I really needed is a monitor that is 80% office and 20% gaming, not 100% gaming. And I believe that's the case with others complaining about the eye strain.
Moisturizing eye drops and Safeeyes (eye exercising Linux app) help a lot though. Safeeyes has an alternative on Mac called EyeLeo (but never used that). Recommend them both to everyone in this thread. Take care of your eyes. They are the most suspectable to drying part of our body - eye exercises help for that. And they are fed with only a miniscule artery, eye exercises help keep a good throughput on that too.
I used an LG C2 42" as a monitor for a few years. The color fringing was particularly bad for me because I like yellow text and LG uses RWBG. 4K 42" and 1440p 27" are about 110 DPI. This is not enough. 4K 27" is about 160 DPI. That is enough. We've already pushed past needing to care about subpixel layouts if you properly weight pixel density in your selection.
Here is a more detailed look at several different subpixel arrangements: https://pcmonitors.info/articles/qd-oled-and-woled-fringing-...
And encouragingly both LG and Samsung were demoing RGB (LED-style) arrangements at CES this year.
It seems that LCD has long been the best technology for desktop monitors - but interestingly, despite its popularity, may never have been the best technology for TVs. CRT, plasma and now OLED have all had better image quality than contemporary LCDs.
https://www.heise.de/en/news/OLED-with-true-RGB-LG-and-Samsu...
But OLED is a remarkably personal technology. Some people also have issues with how the images are "strobed" during upgrades, etc.
If you wan to point out that there is no large OLED display with a DPI > 200, yes that's the real issue at the moment but since 5K displays are becoming more common, I think it will be solved in relatively short time.
But fret not, they announced at CES there will be OLED with vertical pixel arrangements really soon.
> but sir, what about fringing
Skill issue. Just configure your text rendering correctly.
> but sir, what about burn-in
Didn't happen to me.
Which is why I ended up buying a replacement 24" 1920x1080 recently. I needed pixels large enough to distinguish with my fave small font. If I want more pixels at once on the screen I need a larger screen.
The tradeoff is worth it in a lot of scenarios, but I've been thinking about getting a "coding only" monitor that I use for long sessions instead.
I have at least one friend who wants individually-addressible bayer layouts, but that likely won't happen.
OTOH the OLED panels on Apple's iPad Pro series are outstanding, and I'm excited for them to come to MacBooks. Yet another example of Apple's hardware team taking its time to do things right.
> but as noted we found this quite obvious to the eye as well
... and then 2 images that look exactly the same to me :(
