Monitor compatability with new gen x boxes

I would lo love x box to add dragon ball z HD collection to x box new gen✌️

Unfortunately the backwards compatibility program is over so if it hasn't already been made backwards compatible then it won't be.

I tried both a backward compatible game as red dead redemption and the new gen versions of NHL 23 and fifa 23 on the series x version

Thanks - thats a pain. New to having an x box so how were we to know it was not compatible. Irritating.

I'd like to clarify, you don't need a hdmi 2.1 connection unless you want 4k @ 120hz which doesn't seem realistic though i heard r6 siege will support that. Hdmi 2.0 can support 1440p @ 120hz and 2.1 ports are compatible with 2.0 hdmi ports and cords.

Odd thing that these monitors claim to support 1440p @ 120hz through hdmi 2.0 but for some reason don't on the One X, though there's a few that do. I read it's something to do with an unusual refresh rate configuration on one x that most monitors don't support,
so maybe the new consoles will have better monitor support since they're built with 120hz in mind, i guess I'll find out soon enough.

I'm just gonna buy a pixio 278 monitor that claims to be compatible with xbox (it's the one i wanted) and see how it is on next gen, if it doesn't support 1440p @ 120hz I'll return it and buy a px 329 which i know works on one x at 1440p @ 120, just no hdr
support, higher response, and apparently not that bright. Both affordable 2k 120hz monitors though. I'll update this if the px278 works on next gen or not aswell.

I appreciate all answers though.

This problem is with the sound from the X Box One to the monitor speakers (HDMI), replaced monitor and same problem.. Tried external speakers plugged into the monitor and no difference.
