Yes there's a way.

Just connect your PS4 to your monitor via HDMI and your PC via HDMI, too. If you only got one HDMI port, connect your PC via VGA. Or you can just buy a HDMI splitter.

Yo thanks for responding so fast!!! But another question I do have 2 ports but then how do i get them to work. Does one have to be shut down for the other one to work or can I use both the ps4 and the computer at the same time? Cheers

Both of them can be on at the same time. You just have to switch inputs to whichever you want to use at the moment.

For example, I have both my 360 (HDMI 1) and PC (HDMI 2) plugged into the same monitor. Let's say I'm using my PC then all of a sudden I feel like playing some Xbox, I just turn it on (360) and switch the input to HDMI 1. I can switch back whenever to HDMI 2 when I feel like using my PC. Both the Xbox and PC are still turned on.

What kind of monitor do u have? does it work well with ur 360 or does it lad and are there nice graphics??

I use a BenQ RL2455HM monitor. Yeah it works well with my 360, considering it's a console monitor. The visuals look good, not as good as on a PC, but still good.
