I don't get what a "best monitor" is supposed to be. They have six different categories themselves, and there's also pricing. The "best" they listed sucks at HDR gaming and costs $550. In my opinion, if you're going to have a "best" category it's gotta be the Samsung 240Hz 4K monitor, but they mentioned issues with it
So currently, there's no "best" monitor. They all have trade-offs.
