Yeah, computer monitors are manufactured to a different spec than television displays at the pixel level. This is usually called chroma subsampling.
Computer monitors typically are 4:2:2 or 4:4:4 which gives nice crisp and legible fonts. Anything less than 4:4:2 gives me a headache (also Windows....).
Television displays are usually 4:2:0. That's fine for rendering large text that is visible across the room. But trying to edit a word document would be a terrible experience.
I believe they manufacture the television panels with fewer pixel address lines and that reduces the cost. Also, smart TVs sell ads and your usage patterns which are used to subsidize the cost of the tv.
That's why computer monitors are so much more expensive than televisions.
There are plenty of cheap TVs that don't do chroma subsampling. You can't just ignore it, but you can absolutely get a 4K 40" TV that works perfectly fine as a monitor significantly cheaper than one branded a monitor. If you pay attention and use PC mode or game mode with all the processing turned off, you're going to be fine. I do exactly that.
The price difference is way more about economies of scale allowing lower margins and the fact that they subsidize TVs with the bloat. Most people aren't buying 40 inch monitors.
