I recently bought at UHD AU7100 43 inch TV. On the back there are 3 HDMI ports. One of them is marked eARC, and is used for connecting to my soundbar.
Now i bought a Xbox Series X hoping to be able to use 4K at 120hz. I was surprised to see, that option is not available. Since the tv is a 2021-model I believed the HDMI-ports were 2.1, but nowhere ind the documentation I´ve found any information about that. At one point I saw, that best way to connect is via HDMI port4 (game port), but there is no such port.
So what is my best option? I'm not at all happy about 1080p 120 Hz.
Have any of you seen a solution converting HDMI 2.0 ports (as I asume they are) to HDMI 2.1?
