The point of higher resolutions is bigger screens with the same quality.
I was able to snag a 8k 55" tv for USD ~1000 a couple of years ago and it's absolutely glorious as a monitor. Basically it functions as 4 4k monitors in one unified canvas.
When I sit down to work, most of my field of view is screen real-estate. I can have several pages of code vertically surrounded by handfuls of terminal windows and reference material, and it's all perfectly crisp since it's 8K on only 55".
I think we are basically brainwashed when it comes to monitors. Monitors grow a few pixels in resolution and a few inches in size every decade or so, and I've heard the argument repeated - "I got a 21" (22", 24", 27") screen, it's nice but that's as big as I want to go". Somehow when a new few inches larger becomes the norm in the market, everyone thinks that's OK too.
I think most knowledge workers would get hooked on 55" within a few hours of using it. I know I was.
Unfortunately this TV seems to have been a bit of an anomaly. The market today is filled with worse products costing more money. :(
LG was able to make this and ship it everywhere in the world for sub-1000 usd years ago. The technology exists and is not expensive, it just needs to be set free!
