My HP 27mx display. Plugged in PlayStation 5, but screen monitor cannot get to say running at 144hz.  How do I do this?

[savvy2]

your monitor does this, out of spec page,  I have no comments on any game box. (ever)

product ID: 4KK74AA ? (the old model>?)

Without AMD FreeSync

Horizontal: 30 to 89 KHz

Vertical: 50 to 76 Hz

With AMD FreeSync

DisplayPort: 223 - 223 KHz

HDMI: 30 - 223 KHz

1920 x 1080 at 60 Hz (FHD)

where did your read this monitor goes higher?////🤔

Ahhh some do, seems MX means nothing, there are vast sub models of it and  product ID not told by you.

FHD (1920 x 1080 @ 144 Hz)\\

if you have the newer version  MX , the  game box is the problem,  for sure AMD Freesync ,  support'
