I personally think 4K is the "retina" level resolution for TVs (depending how far and what size your TV is) and this type of technique becomes much more tolerable than they were at 1080p or less... it's not a simple blow up of the image, it uses the moving data and the data from previous frames (that were in the other color, as the renderer alternate between the two sets of tiles for each frame) to guess what`s in the areas not being rendered in the current frame, my take is this can be pretty convincing in action, however a little less clean than true 4K. |

85" LED tv for a measly 130k
It depends on size and distance. Taking NHK research about 60cpd (120 pixels per degree) starts "retina" level, beyond 155 cpd (310 pixels per degree) people can't distinguish it from the real thing. https://www.nhk.or.jp/strl/results/annual2010/2010_chapter1.pdf
cpd = cycles per degree, need 2 pixels per cycle (on/off)
They also tested for sense of being there, greater for wider fov. For 8K the sweet spot between realness and immersion is at about 65 degrees. 
Obviously VR has the greatest immersion level at 100 degrees fov. Yet at 120 pixels per degree "retina" level you would need a 12K display for VR.
For a 65" 8K tv, you can sit at 4ft for that retina level resolution with just over 60 degrees fov.
For a 65" 4K tv, you can sit at 8ft for retina level resolution with 32 degrees fov.
VR is the future for high res high immersion experience. The display might need to be 8k or 12k, however with foveated rendering that won't be much more demanding than current 3D 1080p rendering. It's already happening: http://www.extremetech.com/computing/209740-samsung-is-reportedly-working-on-an-11k-screen-claims-it-can-create-3d-illusions and http://www.theverge.com/2016/7/22/12260430/nvidia-foveated-rendering-vr-graphics-smi-eye-tracking-siggraph
Cram that screen into VR glasses with eye tracking, no more need for tvs.
Sorry, got sidetracked. Checkerboard 4K is a nice stop gap for 4K tvs.
