4K Resolution (Ultra HD) Blurays - Are They Worth It?

Just found this sample clip of 8K

On this PC the maximum available resolution is 1920x1080 and both set at 120Hz or 144Hz, when the sample clip is played it keeps freezing, as if it were being buffered (even when the clip is already loaded) so it possibly looks like to play a 8K video on a PC you possibly need a 8K display and possibly a more powerful graphics card

If you have a larger tv yeah you will notice how blocky old SD stuff is. Whats really funny is I have some old 90's TV rips that are half SD (320x240), you cant really see a thing watching on modern 26+" screens unless viewing from a very large distance.

Takes me back remembering about the old video codecs used to use all the time in the 90's and early 2000's which have now mostly faded in to history. Intel Indeo, RealMedia, DivX, Apple Quicktime, WMV, etc...

If you have a large television, say over 50" where the SD is awful when it covers the whole screen, are there options to reduce the size of the picture by half or so so although smaller, it's more watchable?

Reminds me of several years ago I had a customer who bought an absolutely gigantic screen to fit on the wall in their small lounge. Must have been well over 65" although it was slim. It was one of the first affordable large screen TV's and only had SD...and the picture was so blurred it was unuseable, even sat as far away as you could (about 3m if that).
But because they'd spent on it they wouldn't admit it was a waste

Actually, the graphic linked to is incorrect. 4K/2K is not 4096 by 2160 pixels, - that is DCI 4K which is a standard. DCI 2K is as its name suggests, 2048 by 1080 which is one of the resolutions under the DCI 2K spec.. There are more than a single type of 2K displays as the pixels are not always square:

2048x1080 1.90:1 Display Aspect Ratio
1998x1080 1.85:1 Display Aspect Ratio
2048x858 2.39:1 Display Aspect Ratio​

Here is a better graphic that shows a lot more display resolutions, (but not all 2K types):

It's no wonder that most have problems with real display resolutions, - especially when HDMI is designed to negotiate a format that both source and display can accomodate.
