To get retina quality display, you need to match the PPI right? For 5K, 27" is the sweet spot. For 8k, what would be the optimal size of TV?

What you really need to match is the angular resolution in microradians from your eye. You can make any screen smaller by sitting farther back. That said, I do wish my TV was only 42". I guess if you really want the ppi to be exactly the same as a 27" 5K screen, then 27 * 7680 / 5120 = 40.5".

This is exactly the reason I intend to stick with 4k for now: I don't want a display that large. I currently have a 48" 4k display, and I'd prefer to have a 42" or 36" one. (Good choices are hard to find, though, particularly if you actually want 4k rather than ultrawide, want OLED, and don't want to just use a TV.)

A curved, very wide fov screws up the camera projection for most games though.

I wonder what the math would look like to properly render 3D scenes onto a curved display. Could it be accelerated as well as the regular matrix operations used for perspective projection onto planar screens? During the pandemic I did try out my 4K TV as a game monitor. I had a combination of furniture so that I could sit rather close with my eyes approximately half way up the screen, with a keyboard and mouse in a r…

The math is pretty simple to account for a curved viewport, even though I don't think any apps actually care about that. Most displays aren't curved enough to make it a meaningful difference.

We don't have fixed function pipelines anymore either so that could definitely be handled by hardware.

Same for me. I just tried a curved 27 inches monitor and I hate it.

That's too small for the curvature to provide any benefit.

I have dual 27 flat monitors at home and dual 27 curved monitors at work and the ones at work are far more comfortable to use.

Author here, ask me anything! Apart from programming, one of the motivations for getting the 8K display is to look at lidar point clouds. For example the desktop background in my post is a lidar map of Bernal Hill in San Francisco, which I've here downsampled to only 13006 x 7991 px for your convenience [1]. Admittedly, when I bought it at first, I didn't realize there would be so many random issues, as manufacturers…

Do you have 20/20 eyesight, and how tall are you? I use glasses (myopia) and can kind of tolerate the edges of my 32" 4k monitor, but I can't fathom craning my neck all the way up to the edges of a 55"+ display. Not to mention font sizes.

I had a 55" TV as my main display in 2022. Had it about a foot away from my face. It takes a few days, but your brain and body get used to the size.

I just bought a 39" ultrawide and for the first few days I thought "oh dear, I have to keep turning to see the whole thing," but I've not even thought about it for a couple of weeks now, so I guess I'm acclimated.

YMMV.

> The bezels and gaps in between the monitors introduce distractions and one is limited in how one may arrange terminals and windows across multiple displays. To me, the segmentation is a feature. It lets me offload information density and focus. For example, I commonly have an editor on one screen, a browser on the second, and something like a chat app, terminal, etc on the laptop screen.

Nobody's stopping you from segmenting one big monitor into different regions; and you get to choose how big those regions are from day to day rather than being forced into it.

In theory, that would be the solution. In practice I read about all sorts of weird edge cases and bugs when trying to do that.

1080p is good enough for me. I'm not sure buying 3 4k monitors is going to improve my life any, what with my middle-aged eyes and all. Also, old stuff lacks shady smart features. Bonus!

I think monitors are like headphones. Unless you actually try the "better" ones, you don't have a clue what you're missing. I know because I had been saying "Dual 1080p 24" is all I will ever need." for a long time until I got a 4K 50". Now I can't imagine going back.

I checked with my wife and she is unsympathetic to this idea.

Nice to see other people doing the same thing I do, albeit with a 4k OLED instead. I am waiting for an 8k OLED at an affordable price but it seems I will have to continue waiting. What brand and model of desk do you have? I have a 48" TV but I sit rather close so it probably takes up the same field of view as your 65". As to your last paragraph, if you email hn@ycombinator.com and explain the situation, they'll sort…

I have the Uplift 4 leg standing desk [1]. I got the black laminate desktop in a custom 75" x 42" dimension so the whole thing cost me almost $2000. [1] https://www.upliftdesk.com/uplift-4-leg-standing-desk-v2-v2-...

I wish deep desks were more common! Modern ultrawide curved monitors sit way too close for comfort for me due to the way their legs have to be angled further back for center of gravity. custom desks end up being so expensive.

Apple Vision Pro would probably accomplish this

What are its viewing angles?

it's around 100 degrees while humans can see more like 180 degrees (more if you move your eyes; I don't want to move my eyes, I want to gimbal my body to focus on a specific monitor) although outside the center of your vision, you don't have good "resolution". The Vision Pro would be like being inside the sphere, but with a big aperture blocking all the side monitors

I am excited for 8k monitors in the future, because they give you a lot more options for integer scaling than current 4k displays. I know this a nerdish hill to die on, but I hate fractional scaling with the blazing fury of a thousand suns. To get a 1440p sized UI on a 27" 4k display, you can't just divide by 1.5x the OS has to 3x/2 for every frame. OS X does this best as they've had retina displays for a while, but…

I am curious as to what OS's you've tried. Fractional scaling is flawless on Windows and KDE6 with wayland in my experience.

I wouldn't describe any OS as 'flawless', they're all doing what I describe under the hood. QT does have better support than GTK atm. I've also seen bad behavior on windows, esp with older apps. OS X is about the best out there, but even it can have issues with applications that have a view port (i.e. video editors, etc).

I'd prefer to skip all that so I'm happy staying on 1440p until 8k monitors are where 1440p monitors are today with regard to price and quality.
