I only need one, and there are display monitors that companies use for offices etc.

Monitors still exist and they don't suffer from the terrible input lag that most smart TVs have.

Monitors cost 2 to 3 times the price of TVs. And dont come with speakers either.

Well yeah, those TVs are cheap because they use crappy panels and get subsidized by ads. If you just want a cheap panel and driver, you can message a wholesaler on panelook and buy them for like $200 plus some change for a sound bar.

A fast 4K monitor costs ~$700 because it’s a much better product.

Every modern TV has a gaming mode that disables post-processing.

I meant to say pixel response time.
