Why the big fuss on 4K TVs?
(sharing my own thoughts; if this has already been done before, please excuse and mods may delete the thread)
Today we see a glut of ads showcasing 4K or UHD TVs. But before you go broke, please do consider whether 4K TV is really worth it. I have read many article on this topic - a Google search on "Is 4K TV worth it" will yield interested expert views. I am only summing up what various experts have said.
4K Stuff is still long away
What the experts are saying is that 4K transmission and media is still a long time away - three years at least. The reason is plain enough. Some streaming content is available on Netflix and YouTube. But while FHD (1080p) requires a bandwidth of 3~6 Mbps, UHD (4K or 2160p) requires 10-16 Mbps. That is twice as much (naturally so). Most TV shows are still only recorded and edited in 1080p, only movies are commonly made in 4k. It will take a few years for production companies to upgrade their pipelines. It will take a few years for such infrastructure to be ready. It is a massive investment. Production of 4K media (discs) will also take time. Then there will have to be players capable of playing such media. It is not going to happen tomorrow. Maybe, as I said, 3-4 years down the line in USA but in India? We are still yet to get good 1080i HD with excellent bit rate. So you can take a guess.
Do not buy 4K TV to be future proof.
One may say that. But are we really being future proof? An article I read said that current 4K TVs are not future ready because they do not support 4k @ 60 frames per second and 4:4:4 colour sampling. This is not a problem with current FHD BDs @ 24 fps but not for the future. Secondly, many 4K TVs still do not have HDMI 2.0 support which may be required for receiving 4K bandwidth.
Will 4K really make a visual difference?
As per experts, the answer is "not really". They say, this is because of the limitations of the human eye. A chart says that 4K will make a difference only on very large screens such as 60" and above. First the media/source has to be true 4K (we have explored this point earlier). Then viewing distance will matter. 99% of the time, the viewing distance for most people is 7-10 feet. At 8', a 60" 4K TV will just about start making the difference felt. To really feel and notice the difference, you will have to sit closer, much closer. If you have an 85" TV and you are as close as 6-8 feet then and only then you will notice the real difference (and lest one forgets on true 4K source). For 40", you will have to sit at 5' or less, for 55" at 7' or less. And if you do sit this close, you will have to note that you will be blocking the view of a larger audience.
What about upscaling?
Upscaling is a buzz word to attract gullible customers. Upscaling content means that the upscaling hardware/software has to guess what lies in between for the extra pixels. It creates a blurry picture. It is the same reason watching standard channel on your current 1080p is blurry. This blur will be noticeable even at a reasonable distance. So you may have to move back. And at larger distances, the 4K losses significance.
Also to be noted - TVs on their own do not upscale, they merely adjust the resolution. It is like zooming in on a picture. Upscaling is done by media players including DVDPs/BDPs.

So to sum up - save your money. Stick to 2K or FHD for now.
