Xiao Bai wants to know whether the computer monitor can be connected to the computer host and PS4 at the same time.

Yes, but first of all, your monitor must have more than two interfaces and support switching. If there is no switch button, you can only use it one at a time, that is, the computer is not plugged in when using PS4. Aoclv2431dp2hdmi1VGA is recommended. I mean the single switch is automatic, and there are also special buttons to switch. It is convenient to connect pc, ps3 and ps4 now.
