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?

People who buy ultra-high resolution devices (i.e., those beyond the capability of the human eye to discern) presumably are also the market for $5,000 HDMI cables, $10,000 USB cables made from certified ultra-pure copper, headphones which can reproduce 100KHz, etc. In other words, people who have much more money than sense. (Note that this market overlaps the people who own a Bentley used only to go back and forth to the local grocery. Actually, that's not fair -- they are quite likely to also use it to go to church.)

How else should I ensure that all those ultrasound tracking mechanisms [soylentnews.org] work for me? ;-)

Thing is that 4k is still discernible: at close (monitor) viewing distances.
4k for a TV viewing distance is probably a waste of time though.
