Is there a way to remotely control a PC that is connected to your own network without a monitor via a laptop without latency? So that I can use the PC "normally" via the laptop.
I've already tried Teamviewer, but there's always a slight delay.
No, rather not even if you both connect via LAN cable, I do not think that there's latency free. I don't know why you want to do this at all, but I would simply recommend you sit at your PC or live with the latency. And when it comes to video games specifically, I can recommend Parsec.
