What I've read about 4K is that it makes a difference on larger displays, generally 50" and up. There is another technology called High Dynamic Range (HDR) which I'm pretty unclear about but it makes possible things like greater color depth and blacker blacks. This is separate from 4K but they're usually found together. I can sort of see the benefit of HDR on a 14" computer display. 4K? not so sure about that, unless I guess the computer were attached to a large display.
