I'm more interested in why TVs and monitors are considered separate markets. The difference between a TV and a monitor is software, and maybe a display port input for the highest resolutions or refresh rates. This large TV I use as a monitor is great, apart from lack of suspend and an annoying banner that pops up every time the resolution or audio inputs change. And much cheaper, assuming I could find a 43" 4k computer display at all in my region.

Spot on. I switched to a 40” 4k Phillips VA panel (BDM4065) a few years back and can’t imagine switching back to anything smaller. Quite cheap, too. Might not be suitable for colour-sensitive work but perfectly serviceable for VS Code and a browser.

and is 4k, higher refresh rates, curved displays, ultra ultra wide, very very thin (comparying my new to old monitor, and less energy usage; not innovations?

My guess is that most desktop monitor buyers are very price sensitive and largely quality insensitive.

Smaller market?
