The only place I have a keyboard and mouse is wired. All my wireless devices have a controller.

The latency on wired is about 2ms vs 4-5ms wireless, which is pretty good. I do have WiFi 6 everywhere so YMMV. 4-5ms is probably just fine for keyboard and mouse, as long as you’re not a competitive CSGO player or something.

If you’re using Windows for a host you can check out Apollo. It has virtual display support which is pretty neat.
