Hi together,
I am using an Asos ROG Strix Monitor XG279Q and this model supports 2560x1440@144hz native, but it seems it also supports 4K (3840x2160@60hz) as input resolution and the monitor downscale it to 1440.
I received the following results:
Xbox Resolution 1440p @ 120 Hz, allow 4K: yes --> result: maximum 60hz, HDR 10 works pretty well
Xbox Resolution 1440p @ 120 Hz, allow 4K: no --> result: maximum 120hz, HDR 10 is not working
Xbox Resolution 4K UHD @ 60 Hz --> result: maximum 60 Hz, HDR 10 works
My first summary: Basically, I have luck, that my Asus monitor is capable of a 4K signal, although the panel scale it down to 1440p. But on the other hand side - with this setting - I can not use my monitor's very fast panel with 120 or 140hz when I want to use HDR, which of course looks way better than SDR.
It seems that I have to decide between 120 Hz without HDR or 60 Hz with HDR. I would love to change the settings to 1440p @ 120 Hz with HDR on. I am really wondering why this is not possible/allowed.
Would be very interested in your experiences. Perhaps there are some workarounds or Microsoft is considering this in one of the next updates?
Cheers,
Günther
