I have a monitor with hdmi 1.4 that supports up to 144 Hz, I can play with the new xbox 120 Hz or it doesn't work
Hdmi 1.4 shouldn't even support 144hz, it can support 120hz at 1080p.
Yes, but the monitor supports 144 Hz because of DP
That is quite uninteresting, according to the specifications on the xbox page, the xbox series x only has dp, i.e. You will only be able to play 120hz 1080p or 4k60 if you really only have hdmi 1.4 (b).
The xbox has no display port
Eh yes, wanted to write hdmi. Doesn't change anything to the rest of my statement, as it was all related to hdmi.
OK thanks
