So I want you to actually THINK for a minute about what I've previously posted (I know, it's tough!)... here's a link to help you... https://www.quora.com/Why-cant-I-tell-a-difference-between-1080p-and-4K-resolutions-video Now, after you clicked on the link and read (it's only a few sentences and 1 chart, so it shouldn't be too taxing), you'll see that assuming you have 20/20 vision, and assuming a viewing distance of 10 feet, you need at LEAST a 70" screen to see a difference between 4k and 1080p. Now, the VAST majority of people don't have 70" or larger screens, yet their viewing distance is generally 8-10 feet (or more)... Tell me now, is 4k necessary? Needless to say, 8k becomes even less useful.... Now, if you're talking about a 32" 4k MONITOR, which you typically sit a foot or so away from, that's a completely different story. But that's not what we're talking about here! If you're one of those few people with an 80" 8K screen that you sit 5 feet away from - good for you - at least you're taking advantage of your $20,000 purchase.... but I hardly think this describes the majority... Now, as I already posted, this doesn't mean that you shouldn't buy a 4K TV!! If you want HDR 10, Dolby Vision, etc, you don't really have a choice as to your choice of screen - they don't come in 1080p variants. This will undoubtedly be true years down the line once 8K is mainstream - if you want future goodies like "HDR 100, Dolby SuperCool" (yes, I know they don't exist, but there will be some sort of equivalent), you'll probably have no choice but to go 8K.
