May be after 3 - 4 years we will have 16k or 32k or even 64k. But the question is suppose you have a 21 or 32 inch Tv and you are watching TV from 10 - 12 feet away(most of us normally do). Will you see any difference in picture quality for CRT, 720p, 1080p, or even in 4k TV ?:huh
For an example suppose you keep some amount of sand on table. Now if you watch that from 10 inch you will see small sand particles( assume it as pixel). But what happen if you go to 10 to 12 feet away from that. Will you see sand particles?:huh
I don't think so. You will see the amount of sand not Sand particles(pixels) individually.
So I think HD TV is good for viewing from close. What you think? Please reply.
