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?

And yes, it's well worth it. Games look amazing at 4K. I'm sampled quite a few but I can't actually play at that resolution since I'm using a 780ti right now. Framerates are too low obviously, but they look awesome visually when messing around. It's not just games though, everything looks so much better. Text is razor sharp. Like printed in a book sharp. You just don't understand until you work with a high DPI monitor for a while. Plus all the screen real estate! Being able to work in a document and see the entire page at 100% (or even higher if you want), and have another full size doc or a good bit of a spreadsheet next to it is something I never want to give up. 4K video, real high bitrate 4K not crappy low bitrate smartphone or streaming 4K from Netflix, looks stunning as well.
As for a dream setup? My wishlist right now is for a 4K equivalent curved ultra-wide monitor. Like 5184x2160.
