New TV-sets are fast with HDR, so fast in gaming mode that it doesn't even matter. Monitors are out there too, however, even more expensive then some TV's and only giving you like 15ms advantage over the better TV's. So for console gamers, whose XBox's and PS4's are all HDR compatible and more and more playing on HDR Tv-Sets, that would be a welcome addition. Horizon for example was breathtaking in 4k HDR.

This one is the most affordable right now. A lot of reviews out there, more on their way as well. But rather expensive still.
