Any Idea on why I can only get 60hz if I select a 1440p/4K resolution on Xbox One X? 120hz is limited to 1080p.
For 4k 120hz you need more than the 18gbps port on the Xbox one x, there is no source currently capable of this. For 1440p 60hz don’t use port 4. For some reason the hdmi 2.1 port doesn’t like 1440p.
