My ps4 remote play is not working?

Unfortunately, I have no monitor and try so to connect my Ps4 with my laptop. That should really work well on Ps4 Remote Play only with me only a black screen is displayed (see photo).

Now I wanted to ask if someone has a solution for me.

Does your monitor have an HDMI input? - then you could connect it directly.

What kind of system (IOS, Windows, etc.) depends on the monitor? - If you install the corresponding RemotePlay app there, then your PC and your PS4 have to pair at the beginning. For this you need mMn advance a TV (or PSVita) on the PS4, so you can see the pairing code and enter on the PC.

Sorry, just read it again, and recognized that you are trying a laptop and no monitor. If it is a Windows laptop, then it is probably because of the faulty app, the mMn have never gotten properly up and running.
