Cramming more pixels into a small space would only increase cost and negligiable improvement to the naked eyes.

That's like putting 1080P in a 4'' screen. All those extra burn more battery than practical usage.

Also, if we're going 4000P, our living room would be like the cinema, LOL. I am sure everyone lives in such a house.

You are wrong. Pixel density is very important part of picture quality. And at 4k with a 40" we wouldn't even have to run any anti-aliasing.

That´s the truth.   If 1080p is "so sharp" then developers wouldn´t need to use AA.   I have a 50 inches TV, and there some games like mass effect 2 that have a lot jaggies.  MGS4 is a 1080p game and yet I can still see some jaggies.  MGS4 ROCKS!!! BEST GAME EVER!! lol XD

(MGS4 renders at 1024x768 and gets upscaled to 1080p)

Jaggies will still be visible at super high res monitors, the human eye is very good at edge detection at high contrast, but far less able to distinguish fine detail (or slight color differences)

Instead of using brute force and quadruple the resolution you get far better results using proper anti aliasing techniques or proper downsampling techniques from a 4K source video to 1080p.

PC rendering has a much bigger challenge then video since the lens on the video camera does the smoothing/blending for you. Rendering a moving scene is far harder. Edges need to be properly anti aliased and fine detail must effectively be rendered at a higher resolution and be downsampled to get the correct effect, otherwise things like power lines will flicker or pop in/out of existence. The human eye will still be sensitve to high contrast lines suddenly appearing or disappearing on 8k monitors.

A pc scene rendered at 8k displayed on a 75 inch 8k screen will look exactly the same when properly downsampled onto an 75 inch 2k screen viewed from 10 ft away.

Btw 4000p is way beyond cinema, currently 2K is standard, with some theatres (digital IMAX) using 4K projectors. That is 2048x1080 and 4096x2160. You do get 36 bit color and about 5 times the bandwidth of blu-ray in the cinema. Before we increase the resolution I would first like to see an end to color banding and compression artifacts for home cinema.

 

Didn´t know about that thx for sharing the info.
