A:Answer I own this monitor and wondered the same thing when I first bought it. Because it has a micro HDMI port, you'll have to purchase that specific type of cable to connect the PS5 to the monitor (Amazon has inexpensive micro HDMI 2.1 cables). So, in other words, the monitor is compatible to connect to the PS5, but only with a "micro" HDMI 2.1 cable.
The downside is (at the time of this writing) the PS5 does not output 21:9 Ultrawide (or wider) resolutions. So, you'll have to lower your output (black bars) or play with a stretched picture on your display.
I hope this answer helps.
