aoc cq27g1 compatibility with Xbox series x

If it's compatible with Xbox One, it'll be compatible with Xbox One X and the upcoming Xbox Series X, too.

its work, on my S and X on my AOC monitor with a HDMI cable 2.0 i can set on setting at 120hz on old xbox one i can't try it because i don't own the old Xbox One. But i use it on my AOC monitor at 1080p@120hz on my XBOX one X.

It will probably become backward compatible with series x. In this moment the backward compatibility project for xbox one has been stopped, waiting for series x

And, if it were not backwards compatible, you might have to wait until the release of Xbox Series X, as they have said they have stopped working on bringing Backwards Compatible titles to Xbox One until the Series X launch to get Backwards Compatibility
up and running on the Series X. Form there, I imagine they will move back to bringing titles to both Series X and Xbox One for a few more years.

Xbox one isn't xbox one s or x compatible they are all compatible it's only the x that has some enhancements but generally the game will download on any xbox one

Series x is just xbox series s or x

Not xbox one s
