IMO there is no point in buying 4K TV until there are actual 4K content available for consumer use. 1080p seems pretty good enough for home use, even on 100 inch screen. I am saying this considering all the below points I have come to know.
- Currently even HD channels are being broadcast in 1080i only (not even in 1080p) due to bandwidth and cost issues. Forget about there will be any 4K entertainment channel available in near future. (I can bet... forget about India, there will be no 4K channel for next 20 years in India, I even doubt about rest of the world)
- The most advanced format available for consumer use is BluRay discs as of now, that too capable of showing only 1080 resolution max.
- Although 4K TV will be capable of up-scaling 1080p content. But how many of us liked watching SD channels on current HDTVs, SD channels looked better on CRT TVs. Same way we may not like upscaling of HD content on 4K TVs. We are yet to see how good a 1080i or 1080p content will look on 4K TV.
- [citation needed - consider it a rumor till then] I read in an online article that a compression algorithm is developed which can accommodate a 4K movie of 2 hours into a dual layer BluRay disc without loosing any quality. Even though that is possible, current Hardware systems (like Bluray Player, cables etc.) may not be compatible or capable to deliver 4K content.
- Currently REDRAY is the only player developed for playing 4K content, that too just seems like a protocol.
Before any 4K player comes into picture for consumer use, we can expect another format war. All the studios and production houses will have to come to a conclusion for a standard 4K format, before they start producing 4K content for consumer use.
