This was an interesting watch and brings home the fact that you should just consider what you are needing your screen for. TVs are certainly also getting better, but there is more to it than just HDMI ports, contrast ratios, and response times.
We’ve long been using our standard (and now pretty old) TV with HDMI ports as our media screen in the lounge, connected to a Linux computer. It works perfectly for that purpose. But we’re not playing high-end games on it.
But even for many gamers, MAYBE a TV could work fine. Given the price differences, it may be worth it. As it is, many say that the ultra-high refresh rates (or FPS) we are seeing on the latest monitors are just not good bang for the buck at all. It is unlikely the human eye is even perceiving much difference beyond 144Hz (I did a post about that in June 2023).
It is certainly something worth considering at least.
