frm reading this prism monitor specs...firstly this monitor is hdmi 2.0.
since its 144hz, at hdmi 2.0 hitting 1080p at 120fps shld be no problem, but for any higher resolution wth 120fps wld definitely need a hdmi 2.1 display/monitor.
this prism model, need to doublecheck if its hdmi port rlly support 120hz.
BTW currently ps5 dont have any true 4k/120fps games at all.
in the very long long future might have. what ps5 have is only a handful of 1080/1440p + 120fps games.
standard for ps5 fr a long time wld be 4k/60. its still very new, as newer games just starting only to have this. older games just started to have it also after patches and upgrades.
the one that have 4k/120 games is xbox. this one..someone who have experience with having xbox seriex pairing with hdmi 2.1 monitor/display might be able to confirm.
but anw main point is, if want play game that is higher than 1080p(1440p to 4k) at 120fps need hdmi 2.1 monitor/tv display.
