As someone who wears corrective lenses for astigmatism, I can guarantee that what you perceive as a straight line, assuming you are human, is not, until your brain corrects it and signals 'straight line' to you.

It takes a day or so for your brain to get used to any consistent distortion and totally disregard it.

This is just pointless complaining... A bigger complaint with curved screens is: crazy reflections.

As someone who wears corrective lenses for astigmatism, I can guarantee that what you perceive as a straight line, assuming you are human, is not, until your brain corrects it and signals 'straight line' to you.

That is unrelated to astigmatism. In Art 101 class in college we explored this phenomenon. It's caused by the spherical nature of the human eyeball.

The exercise was to sit on the floor in the corner of a particular campus building that had a lot of long architectural lines and draw what you see without looking at the paper. If you drew straight lines, the prof knew you were thinking about drawing, and not just drawing what you saw.

SomeHacker44 9/13/2025|||
Not so sure. When I first started wearing glasses for astigmatism, it turned rectangles into trapezoids. Totally destroyed my depth perception. After a while I got used to it and stopped walking into curbs and buildings. Later in life I moved to progressive lenses. The straight lines then became curves. Adjusted after a while again, but the curves never fully went away. Regardless, I have to take the glasses off for sports that require good depth perception like ping pong or tennis.
somat 9/13/2025|||
Sometimes my depth perception goes off after getting a new pair of glasses with no prescription change, I always figured I had ended up with a different IOR poly-carbonate formulation in the lenses. But I have no idea if that can actually cause the effect.
mcpeepants 9/13/2025||
I experience this too, and always thought it might be caused by a change in alignment of my eye and the “center” of the lens with new frames and lens shape.
namibj 9/14/2025|||
Use contacts for astigmatism they need to be "fixed" to the eyeball to properly correct astigmatism.
orbital-decay 9/13/2025||||
Yeah. If you try hard enough, you can slightly break the correction and directly notice the curvature of the straight lines, especially long ones moving towards you, on the border of your visual field. The eye physically produces a heavily distorted picture, but it's at least partially rectified and the brain does a sort of continuous neural SLAM, what you perceive is the result of it.
sigma02 9/14/2025|||
What I said applies to any distortion. Astigmatism is just one example. Lenses that turn everything upside down is another. A few hours later, everything is normal.

I had this experience back when the glass on CRTs was curved and monitors started shipping with knobs to adjust the curvature of the image. I had used a curved-glass CRT (curved the opposite way of today's curved monitors) for so long that nothing looked quite right after that until LCDs came into the picture (pun intended).

Did it ever happen to you, that you are not dealing with humans and therefore you noted this assumption?

Though I suspect their visual system works the same way.

LocalH 9/14/2025||
This is very true. I've been measured as having astigmatism. However, I do not wear corrective lenses for astigmatism (only for general near-sightedness), as my brain has been correcting for it for the better part of 45 years at this point. I was told if I wore corrective lenses it would start giving me headaches.
sippeangelo 9/12/2025||
I like my curved ultra-wide. I didn't at first, but my brain has very noticeably adapted to where curved things on it appear straight just fine. I noticed this when I went back to the office after a few weeks absence, where I have a regular flat pancake screen in 16:9, and straight text looked CURVED in the opposite direction!

Brains are weird.

hakunin 9/12/2025||
I got a curved 5k2k lg display for games, and every time I switch to work monitor (5k regular flat lg), it feels like I'm looking at an old CRT that's bulging out at me. Such a strange sensation. I do like the curved display a lot however.
zeroq 9/12/2025||
Wow, that's a great insight and honestly a great point for not having one. At least till they get more popular.
hakunin 9/13/2025||
To be fair, this is a short lived effect immediately after transition. Goes away in 2 minutes.
DamnInteresting 9/14/2025|||
I have a curved monitor on my regular desk, and a flat panel on my treadmill desk. Switching between the two takes a few minutes of adjustment for things to look right.

I had a similar peculiarity with eyeglasses. I'd always had great vision, but middle age recently hit me like a truck, and my eyes have started to go. I got a prescription, and there was a difference between the two eyes. For the first few days, everything looked misshapen, larger on one side than the other, until my brain compensated. Most curious.

AdrianoKF 9/13/2025|||
I've noticed the same when I tried to replace my ultrawide 34" with a Dell U3225QE for my home office the other day. I really wanted to like the Dell since I love the specs, but my head would hurt from the perceived bulge in the middle of the screen, where the curve used to sit farthest before. Stupid brains, really.
ChrisMarshallNY 9/13/2025||
I use a 49” LG ultrawide (5120 X 1440).

It’s curved, and I have no issues at all with it.

I thought I would, at first, but it’s been fine.

But it’s also only curved horizontally. Not sure how it would be, if it were square.

Jedd 9/13/2025||
TFA doesn't mention the size of their monitor, or the ratio of it, or the distance they typically sit from their monitor, or the horizontal placement (relative to their eyeballs), or the type of work they're doing.

I'd also expect a mention of the amount of curve they are upset about.

There's a few varieties, the 1500R and the 1800R were the most common two when I was shopping last year, in the AU domestic market. Those numbers refer to how the monitor might fit on an imagined circle's radius (measured in millimetres, naturally). So an 1800R is a gentler curve than a 1500R.

I find UW's beyond about 34" are mostly more comfortable in an 1800R for 'office work' activities (not including CAD, photo / image manipulation, etc) and gaming.

(I actually have a 43" flat, in 16:9, it sits about a metre from my eyeballs, and I usually aim for my eyes to be about 1/3 the way from the top of the screen. After several months with this, I now feel a gentle curve on this would be a bit more ergonomic.)

bpye 9/13/2025|
I have the Dell U4025QW which has a 2500R curve and I do think it’s beneficial. If I had dual 27” monitors instead I would also have a slight angle between them - so the curve seems like a natural progression.

Different people have different preferences.

I suspect a bunch of smaller manufacturers would have more success with their products if there was an easy way to try them out for a week or two. Buying hardware sight-unseen incurs a heavy risk penalty. Buying it after seeing it in a store for ten minutes is some reduction, but not a lot.

How many people would spend $250 on a split ergo ortho keyboard having never touched anything other than a laptop or maybe a mushy $12 pack-in included with their Dell at work?

What's the appropriate solution other than inflating the price even more to cover a generous return policy?

I might buy a Keyboard.io or a Moonlander... but there's a pretty high risk I won't love it. These things can be subtle: I quite like the X-Bows Knight I'm typing on now, and can't stand the Keychron Q10 which, by all rights, I ought to find about as comfortable.

lisper 9/12/2025||
Once upon a time there were these places called “retail stores” where you could go look at actual products and even try them out before buying them.

Alas.

dsr_ 9/12/2025||
That works for a conventional mouse: you've used one before. This one is a little different shape, a little bigger, ooh, no wires. That's fine: in five minutes you know whether it's OK.

How long does it take to decide whether you love or hate a thumb-ball? A big ball? A SpaceMouse? Has anyone who didn't use a ThinkPad decide to buy a keyboard with an integrated nubbin?

Sure, I can buy twenty devices for $200 each and return 19 of them. That puts 19 items into "open box" status, causes me to re-pack and re-ship and track 19 items, and makes 19 vendors vaguely cranky at me.

matsemann 9/12/2025||
I get your point. When I had RSI in my right elbow and tried to find a replacement for a traditional mouse there were soooo many attempts. And I had to use them for a while both to see if they helped, but also to see if I managed to use them properly. Like, a mouse where you rolled a ball with your thumb I never got friendly with even after a few weeks.

In the end the problem was actually moving the hand away from the keyboard, so no tilted mouse, thumb mouse or track pad worked. A RollerMouse saved me. I even game with it now, heh.

Just lucky my company paid for all of it (and the ones I didn't use they got back by me distributing to others within the company with issues)

comprev 9/12/2025|||
Over the years I've gifted a few nice keyboards to people and their immediate response has often been "why didn't I get a proper mechanical keyboard sooner!"

They had only used cheap plastic or laptop keyboards until then and never saw a keyboard as a tool to invest in for their profession (which often required plenty of typing).

snickerer 9/13/2025|||
I bought a Moonlander two years ago and the price (plus shipping to Europe) did really hurt. I also had to spend a lot of time into the complex configuration of the individual key mapping. And to learn the mapping.

It was absolutely worth it and I would do it again. I love that the keys aren’t staggered like on a typical keyboard — which I find rather silly — but instead are perfectly aligned in straight columns. And the thumb keys. And the configurable chords (yes, chords, that's nerdcore). And much more.

physicles 9/13/2025||
I bought a Voyager about a year ago. On day 1 I nearly had buyer’s remorse because I topped out at about 20wpm, even though all my keyboards have been ergo since 2001.

After more practice, and after swapping out the key caps, I now think this is possibly the last keyboard I’ll ever buy. I’m having a hard time imagining anything better (though I could use maybe 1 extra thumb key on each side).

diggan 9/12/2025|||
I'm not sure where you're based, but don't you have consumer protections that allow you to return goods you regret buying? I know that even in places with good return regulations, there are exceptions, but where I live, I could buy a monitor from Amazon to try it out, and if I don't like it, just return it within the 30 days and buy another one. I assumed it was like this in most of the western world? Maybe I'm a bit naive.

I know a bunch of people who do this for cloth shopping (which isn't a great idea considering everything else except themselves, obviously), where they don't know exactly what size will fit them, so they buy the same dress in 2-3 sizes, try them out at home then return the ones that didn't fit.

1. While many places have no questions asked return policies, many also have more stringent return conditions, such as not allowing exchange for dissatisfaction. For tech retailers, where the margins are low and the goods value is high, I often find they're worse than with clothes, for instance.

2. I did some cursory searching and it doesn't look like even EU guarantees the right to return for satisfaction reasons. The closest is the 14 day right of withdraw for distance purchases, but that can be waived and doesn't cover in-store purchases.

3. Even when returns are theoretically allowed, there are many ways for retailers to make it a hassle, such as not covering return shipping, which for a monitor could be a sizeable amount of money.

II2II 9/12/2025|||
I'm fairly certain such regulations don't exist anywhere. They would be far too easy to exploit, raising the cost of doing business and exposing them to outright fraud. Regulations meant to protect consumers usually protect them from dishonst business practices.

The type of return you're talking about is usually intended to encourage people to make a purchase and to protect the reputation of a business. Yet the moment they detect abuse, abuse being return patterns that are atypical or that will end up costing the business more money in the long run, you can be sure they will stop honouring their return policy.

frotaur 9/13/2025||
This is 100% a European law that exists. You are entitled returns within 14 days of purchase for most goods. No reason need be provided.

Pepperidge Farm remembers when Fujitsu computers (those assembled in germany into the 2010s) used to come with rebadged steel-plate Cherry keyboards. Okay, they had mushy browns I think, but still. You go unpack the bundled keyboard and it weighs a kilo. They were still rubberdomes (G83 I think?), just really nice ones.

Was there actually more to this posting and it got cut off? I'm not seeing why this is a practical issue. I'm partial to large displays with a more traditional aspect ratio, but using ultrawides, including curved ones occasionally isn't annoying to me. What really grinds my gears is that one coworker who doggedly insists on sharing his full desktop every single damned time which makes text nearly unreadable on anything other than another ultrawide.
matsemann 9/12/2025||
I don't mind curved screens, but what I do mind is that so many wide / curved screens have such low vertical resolution. 1440px is just so little space.
jsheard 9/12/2025||
It's a cost thing, ultrawide has always been expensive relative to how much extra area you get, and pushing the resolution up compounds that. 5120x2160 (extended 4K) panels do exist but they cost a fortune.
Kon5ole 9/12/2025|||
But why is it a cost thing? I got a 55 inch 8k tv for less than 1000 usd years ago, including sales tax and overhead from a physical store. It’s the best monitor I’ve used.

Today, many years later, monitors are still way worse and more expensive! Also you can basically not buy the tv’s anymore either.

The panel factories existed, and the panels were cheap, years ago. They’re just not used anymore (or so it seems).

Dell UltraSharp 40 Curved Thunderbolt™ Hub Monitor - U4025QW

Worth every penny.

digitalsushi 9/15/2025|||
I have a U4025QW and there's a glitch I'm typing here for google to pick up.

If my macbook (any macbook, perhaps any computer?) is plugged into the U4025QW and the power goes out, the U4025QW won't get the signal from the laptop and will remain blank. There's two ways to 'fix' this:

The first is to unplug the monitor for a long time, perhaps 2 to 4 hours. Sometimes I'll plug it back in at hour 2 and it wasn't long enough and I'll have to start over.

The second, and this works reliably, is to unplug the U4025QW, and then also unplug the monitor side of the HDMI cable, and then plug it back in with no signal, and then reinsert the HDMI cable. This gets the U4025QW to receive the signal after as long as the above operation takes, a minute or so.

I have had two U4025QW units. The first one was overheating and losing the signal as above on its own. I stopped having overheating issues when I stopped using an undersized UPS. I ran it straight into the wall.

But if there's a power outage (i live in an area with monthly power outages), the signal loss operation is how I restore functionality to the U4025QW.

I finally got one of those 300 dollar UPS units for the U4025QW and it's been very stable since then.

A multi variable episode that took me a very long time to reduce. U4025QW is a great monitor but dont give it bad power and it needs a little love after a power blip.

jsheard 9/12/2025|||
LG has a 5120x2160 OLED already, but it's 45" so the pixel density isn't great. It's also stupid expensive, about double the cost of a regular 4K OLED for 30% more width. They have 39" and 34" variants on their roadmap though.
skhameneh 9/12/2025||
True, that is an option I forgot about. I generally don't see it any better than a standard 16:9 OLED given the price and limited (in comparison to 32:9) width though.

> the pixel density isn't great.

I got one of the 49" 32:9 OLED and it has 1140 vertical. I'm making due with it and had to tweak settings like crazy to make it tolerable... I'd love a proper 2160 option for the ratio. I came from a 28" 4K TN panel, so it's been a major change of tradeoffs.

It's hard to justify the higher price on the smaller 45", it makes it a hard sell over a standard 16:9 ratio 4K OLED (although I wonder if that would have been the better choice over what I got).

I just recently picked up a 32 inch curved 1440p screen and it's awful, for that size I should have realized I needed a 4k. Text is horribly pixelated and when looking dead on it feels like the aspect ratio is closer to 4:3 or something. Coming from an ultra wide 1440p I'm really disappointed.

My holy grail of computer monitors is an 8k 55" curved screen. Not a shorty, but a full 55" or 65" 16:9 (or similar) screen with 7680 x 4320 resolution, but curved.

I currently have three 4k 32" screens in portrait arranged in a sort of curved configuration. I love it, except for the bezels. It's something like this: https://i.sstatic.net/YocaE.jpg

I was almost ready to purchase a flat 8k 55" TV for my workstation, but decided to try a flat 4k 55" TV I already had, and the flatness just ruined it for me. I need a slight curve when using such a large surface area only a few feet from my eyes. I guess I'll have to stick with my three 4k monitors for now.

JonChesterfield 9/12/2025||
You might like a larger one in landscape in the middle, keeping the two 32" in portrait either side. Angled inwards.

I did not check the physical geometry so the side screens are taller than the center but whatever. 43" flat center, 32" either side. Felt strongly like a mistake when first set up but has grown on me.

For a 34 incher, 1440px is perfect, and so is a 34 incher. A higher resolution renders text too small to read, and a larger monitor has one moving their head around instead of just their eyes.

Of course, they are not ideal for the graphical work that the author implies, but they can't be beat for productivity work imho.

> A higher resolution renders text too small to read

This is a misunderstanding of what higher resolution is for. Higher resolution allows text at exactly the same size to be much sharper and crisper. I have a 34” curved 1440p, and it’s like using a monitor from the pre-HD era in terms of sharpness. Other people in this thread have observed the same thing. The idea that it’s “perfect” is unfathomable to me.

kasabali 9/13/2025||
it's not a misunderstanding, it's reality. yes in theory you can render text in dimensions you want, but in practice we have like 20 different UI systems running at the same time and each have their own quirks and limitations and the end result is unless you're using 96dpi or it's exact multiples. either som ui elements will be looking ridiculously out of proportion compared to something else, another element or image will look like a blurry fudge, and the end result always looks horrible.

Are you thinking of Windows perhaps? Mac and Linux can both handle this well. Even on X11 (which is old and limited in many ways), on 4K monitors global scaling of 200% works really well. But Windows has legacy apps that are bitmap-scaled, which apparently leads to blurriness (I’ve never seen this myself, only read about it. I’m allergic to Windows.)

For the investment of one image, maybe a second image might have made your point. I don't like curved displays either, but I observe many widescreen photos offer a distorted view of the scene taken on a large flat monitor, since the lens is a compromise as is printing on flat media, and so the image as presented from a wide-angle is NOT accurate, any more than a curved screen of a 55mm lens would be. The problem here is horses-for-courses: if you have a wide curved screen then you should ask your digital devices to render images as if they are being displayed on a curved surface, not as if they are flat.

Anamorphic lenses should be projected/presented on curved surfaces and packages like Hugin will render images which should look pretty good on a curved surface of a known radius, assembled from sets of non-curved flat images put together in a panorama. Or apps like Bimostitch on android, which looks to use the same algorithms.

I don't like curved screens because I haven't learned to rotate my head the way needed to deal with content on the edge. I like dual monitors in a V more than a single wide-screen because they can be independently desktop-panned, only some widescreens do this (by s/w rendering it as two heads)

For some work (Audacity - audio editing, and related video work) a wide screen is fantastic. Horses for courses.

hnuser123456 9/12/2025|
This got me thinking, are there any games that have a graphics setting for monitor curvature? Because they should, IIRC the standard is rectilinear rendering, where the perspective comes out correct only if the monitor is flat. But if people can get used to glasses that severely distort the image, I guess this isn't a big deal.

Also, my obligatory rant, ultrawide monitors do not exist, only ultrashort, and 16:10 shouldn't have become a "premium/business/designer/prosumer" option, it should just be the standard. Nobody gets a VR headset and crops off the bottom and top thirds of the image and claims it's more immersive that way.

drcode 9/12/2025||
I don't like straight displays, things at the corners are a different size than things in the middle, because they are further from my head. On curved displays, objects on different areas of the screen are the same size as they originally appeared.
diggan 9/12/2025||
> I don't like straight displays, things at the corners are a different size than things in the middle, because they are further from my head.

Are you sitting really close or have a really enormous monitor? Measuring how I'm sitting right now, my nose is exactly 61cm from the center-center of my monitor, and ~72cm between my nose and any of the corners, and it's a 32" monitor.

I'm usually sensitive to things not being 100% straight/level/aligned, and if I create five identically sized windows and put them in the middle and one in each corner, I see no difference between them.

marginalia_nu 9/12/2025||
The distortion is mostly a problem with ultrawide monitors, which typically have the pixel density of a regular 16:9 monitor, but with twice as width.

Flat ultrawides are an especially miserable experience, where the sides of the monitor are viewed at a 60 degree angle, a pronounced deviation from the 90 degree angle in the middle.

Yeah, projecting onto a plane instead of a... spherical dome? means that things at the border of your screen are more visible than the things at its middle which definitely not how eyes usually work.

It's especially glaring when the far plane serves as the place where the view-distance limiting fog is rendered: if there is some thing barely visible before you, turn 45% to the side, and you'll see that thing very clearly at the side of your view.

Would the author of this post have enjoyed or hated seeing a movie in Cinerama? Anyone who has been seated too close to a flat IMAX screen knows that even a flat screen can give a severely distorted viewing experience if you're not in a good viewing position (e.g. if you're seated off-axis and close).

In recent years, curved panels have been a way to compensate for issues created by limited viewing angles offered by LCD screens. If a screen is sufficiently large and the seating position close enough, one could often see a pattern on the screen even when viewing a single solid colour. The choice of screen geometry was a choice between different forms of image distortion. As technology improves and viewing angles become wider and more consistent, we'll probably see curved panels become more niche again.

I use a nice 32" 4k IPS panel for work and it's borderline OK in the corners. However I got a really wide curved screen for a second computer and in that case I really appreciate the shape just because it mitigates the distortion somewhat.
