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…

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.

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.

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, b…

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.

No, I wouldn't like that. I want one massive curved high-resolution screen with no bezels.

Little curve good, big curve bad. Imagine its 20 years ago before these monitors were made and you had multiple monitors. Ever see a dashboard chihuahua? (Or on the rear deck of a car). Thats you if you use a multimonitor setup. Do that for even 10 years, your neck hurts and your focus is distracted because you cant look straight ahead at your work and are constantly turning your head from left to right all day. Its…

Is turning you head left and right really worse for the neck than rigidly keeping staring straight for hours? Somehow I find it hard to believe.

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 imag…

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.)

> global scaling of 200% works really well

I've already said that.

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.

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.

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.

I can almost see this complaint with poorly designed (ie, common and cheap) polarizers in LCDs and/or non-IPS/IPS-like LCDs at normal DPI. However, that doesn't really work with OLEDs or MicroLEDs at any DPI, or any HighDPI IPS/IPS-likes. Also, ultrawides are pretty rare. Multiple monitors have a lot more use, are a lot cheaper per pixel, and back to gaming again, a lot of games simply do not support anything but the…

It's not the matter of viewing angles. Distances. Try calculating distances between eyes to the edges of especially ultrawides, for which curved displays are pretty common. Standard recommended distances between head to display is 50cm(20").

Optimal viewing distance for most media (including text found in programs and websites made in the "Vista" and "Retina OSX" era to today, but also all movies and TV shows cut for modern 16:9 displays) is between 30 (SMPTE rec.) and 40 (THX rec.) degrees.

THX's recommendation is based purely on the viewing angle of the fovae (the inner part of the retina that is "high res"), and trying to optimize full coverage of it (ie, pixels on the screen should not fall outside of the fovae).

Microsoft, during Vista, and Apple, during the evolution of OSX, both standardized font sizes as a little larger to make all text sizes comfortable at the 30 to 40 degree range. 30 degrees is * 1.6 diagonal size, 40 degrees is * 1.2 diagonal size.

So, if you have a standard 24" 1080p monitor, that is 28.8 to 38.4 inches, not 20.

SMPTE and THX did not change recommendations for 4k, as the view angle of visual media (ie, the focal length in movies/TV shows) did not change, and text doubles in (pixel) size (but not apparent size) to accommodate it; ergo, do math as if you're on a 100% DPI display. Ergo, 24" 4k would be the same.

Also, for completeness sake, 27" 1440p are rare, but a bit more common with gamers, and their math works out to be between 32.4 and 43.2 inches. This is assuming you adjusted your DPI to 133% and/or you're purely focused on movies/TV and games; if you consume only text and stay at 100% and never view media, you may wish 24.3 to 32.4 inches instead.

Use contacts for astigmatism they need to be "fixed" to the eyeball to properly correct astigmatism.

I'm not sure if I understand your thought process. I'm talking about distance errors between center of screen and edges of the screen, not singular distance. Frankly you can just paste this to ChatGPT. It's correct enough for this type of topics.

> let distance between head to display 20 inches, screen width 20 inches as well, tell me how to calculate distance errors between center of screen to edges of screen

^ this yields a figure of 2.36 inches among few kBs of padding data

> does that mean the eyes need to be refocused when there's distance error of 2.36 inches, ok to go step by step for this

^ this yields a figure of 30 um among few kBs of padding data

> does that mean the eyes need to be refocused when there's distance error of 2.36 inches, ok to go step by step for this

^ this yields such elaborate responses as "Estimated DoF is about ±1 to 2 inches around the focus point", "Yes, the 2.36-inch distance error is right at or slightly beyond the typical depth of field of the human eye at 20 inches.", "The effect is subtle, but in precision tasks or long durations, your eyes may notice the strain"

Which are all more than correct enough. btw the math is mostly just basic Pythagorean theorem so not hard to follow.
