Best 4k gaming monitors?

I'm looking for a good 4k gaming monitor that supports the features of the xbox series x. Price shouldn't be over 400

There's no such thing as "the best" monitor

And it would be interesting how big the monitor should be
(I recommend 27, better 32 inches and larger)

Doesn't have to be the best. Not larger than 28 inches and, as I said, the main thing is to support the new features of the new consoles
