The top google hits say that there is little or no benefit to resolution above 4k. I recently bought a 40" 4k tv which I use as a monitor (2' viewing distance). While this is right at the threshold where I'm told no benefit can be gained from additional resolution, I can still easily discern individual pixels. I'm still able to see individual pixels until I get to about a 4' viewing distance (but I am nearsighted).

I did some research and according to Wikipedia the Fovea Centralis (center of the eye) has a resolution of 31.5 arc seconds. At this resolution, a 4k monitor would need to be only 16" at a 2' viewing distance, or my 40" would need a 5' viewing distance.

Now the Fovea Centralis comprises only the size of 2 thumbnails width at arms length (2° viewing angle) and the eye's resolution drops off quickly farther from the center. But this tiny portion of the eye is processed by 50% of the visual cortex of the brain.

So I ask, are there any soylentils with perfect vision and/or a super high resolution set up, and does this match where you can no longer discern individual pixels? Do you think retina resolution needs to match the Fovea Centralis or is a lesser value acceptable?

My 40" 4k at 2' fills my entire field of view. I really like it because I have so much screen real estate for multiple windows or large spreadsheets, or I can scoot back a little bit for gaming (so I don't have to turn my head to see everything) and enjoy the higher resolution. I find 4k on high graphics looks much nicer than 1080p on Ultra. I find the upgrade is well worth the $600 I spent for the tv and a graphics card that can run it. Have you upgraded to 4k and do you think it was worth it? I would one day like to have dual 32" 8k monitors (not 3D). What is your dream setup if technology and price weren't an issue?

    nearsighted people see near things magnified.

    Got me a 3 K monitor once, but the white balance was off, and the KKK wanted it back immediately (curious bunch of people).

    I chortled at that.

    Just today I ordered a second 4K screen for my office, because the first has just been too awesome for the antiquated 24 inch wide screen to remain alongside it. I've heard of Windows 10's quartering feature; how can I get the same on Linux or Windows 7?

      Some googling got me to X Tile: http://www.giuspen.com/x-tile/ [giuspen.com]
      Looks slightly ancient, but useful and customizable.

      Considered a tiling window manager? If you're completely anal^W^Wparticular about your window placement that really may be the thing for you.

      In Linux you can just use a tiling window manager like TMB suggests. The most popular flavour is dynamic tiling, where the windows split automatically as you add more, but I tend to prefer static tiling. My everyday driver lately has been Notion [github.io] across four screens, though I've also spent some time with herbstluftwm [herbstluftwm.org].

      I have a basic set of splits set up the way I tend to want them, can have multiple windows in a single frame (notion does tabs as well as tiles), and can alt-tab to swap between tabs within a frame. If I need more fine-grained splitting there are hotkeys and mouse shortcuts to do it, same with removing a split when done. Plus each monitor has its own set of virtual desktops, so I can use multiple sets of splits. Meta+[0-9] swaps workspaces, so it's easy to have a program that needs a lot of space in a single-frame workspace (equivalent to 'maximising' a window) while still using the normal splits for everything else.

      They take a bit more work up-front than a traditional stacking window manager, but it pays off long-term because you don't constantly have to futz with moving and resizing windows because the window manager decided to "help out" and put shit in a dumb place.

      I don't use Windows, so I can't say much there, but try searching for "Windows 7 tiling window manager" and filter out the search engine's inevitable deluge of Linux options, maybe you'll find something useful. I can't speak for the quality of anything, but a couple first-page hits were bug.n [github.com] and aquasnap [nurgo-software.com]. It looks like they're cheating a bit by trying to work around the normal Windows WM's behaviour, so it won't necessarily be as nice as a proper tiling WM but could give you something similar.

    Using the edge of my glasses to compare between corrected and uncorrected, I can tell you the image in my glasses is somewhat smaller than uncorrected.

      Yes I meant the uncorrected is magnified. That's why the stellar Donald Pleasence in The Great Escape could spot little details in forged documents.
