It is just like 8K as it stands at the moment 72” TV is minimum size advised.
Until TV broadcasters start outputting 8K it will not take off, also advancements in tech is needed. There is a certain distance to sit back from 8K display to get true 8K details. With TVs needing to be so big and distance from viewing its not ideal for standard homes at the moment.
Small 8K TVs will give you same results of 32”/42” TVs outputting 4K.
Theres no big demand for 8K.
To expensive.
To before its time.
Lack of 8K content.
4K will dominate and continue to grow. 8K is atleast 4 or 5 years away for the ordinary man in the street price wise, and tech needs to develop as cant see many putting 80” or 90” TVs up to see true 8K.
Certainly not ideal for a one bedroom apartment.
