Does the xbox one x already support hdmi 2.1 or still not?
The console came on the market in the middle of 2017. The HDMI 2.1 standard was not specified until the end of 2017 … So what should not that be? Of course not.
Besides, the console manages to get 30fps @ 4k, what do you want with 120Hz?

Quite a mistake the answer… The X1X has a hardware solution that makes it possible to upgrade the support for HDMI 2.1 via a software update.
