> the same "tech", just to different specifications to fit their desired purpose/niche
Clearly not. I am using a TV as a monitor right now, because 4k + OLED + HDR + 120hz was just not available for $1100 in the monitor space six months ago (I think there was a $6000 offering, lol). Looks like it still isn't. This situation has been going on for years. Before OLED it was HDR, before HDR it was 4k, and so on. TVs are always far ahead, monitors are always far behind.
I'd rather not use a TV as a monitor because it's a PITA. I have to put up with substantial non-panel-related silliness to make this happen (turn the TV off/on with a remote, deactivate the laggy filters, tolerate the "smart" BS, etc). If monitors are so well tailored to their own niche, why are they losing so badly to a competitor who isn't even trying?
> to capture the maximum possible value from that market
That's the only explanation I can come up with: monitors are a backwater that the industry just doesn't care much about because volume is lower. Tech has to trickle down, and that takes years.
