I'm on holiday with my family for a week in Lithuania for a week and so I wanted to play there as well but I will not have a TV in my room. Is there a cheap adapter with which I can connect my Xbox One X or my PS4 Pro to my laptop? Did not find anything on Google.
No, that's not possible, since most laptops have only one signal output but no input. Unfortunately, there's no adapter. So it helps only a small monitor or TV.
Arrives at your laptop but not really.
You can buy a CAP card for PCMCIA or for USB.
However, has a strong delay and is therefore hardly suitable for games.
Almost cheaper and of course better to buy a small mobile 12 "TFT, this is around 35-50 euro.
