I've already researched this question.
Apparently you can use the laptop with a video capture card as a monitor for the Ps4. And would like to know if you can also use the keyboard as a controller for the Ps4. I could use remote play and a (controller emulator for keyboard) program use but the resolution is not very good and neither is the quality.
No I don't think so. You connect the mouse and keyboard to the PS4 via USB and we will recognize it accordingly. You can try it, but would connect an external keyboard
In principle, just use remote play from the start, but you will probably find it difficult to play with the keyboard because the controller is still indirectly connected to the PS4 / 5 via a signal while remote play is used.
Thanks for your answer, but as I said, the resolution is bad and I would therefore like to try it with a video capture card.
Resolution always depends on how good your laptop is and what kind of performance it manages, of course you won't have high-end graphics, but also not bad ones if you don't have a bad laptop.
Thanks for your answer, I'll try it, but do you think it works for every game, for example shooter games like Cod Cold was?
Well with remote play there's a maximum of 720p. No matter how much power I have, it won't be over 720p so I would like to try it with this video capture card because I can connect it directly with HDMi
I don't know if everyone can do it, but I'm pretty sure that you can play it with a mouse and keyboard. With Modern Warfare it definitely worked.
