in VR mode,how to let PC show 1920*1080 single screen

I think I figured it out. I stopped using the --vr flag, because I guess it’s not really necessary, and then I realised that I need to press T on the server and then the client is now controlling the VR Character and the server is doing the non stereo mirror. Why does “T” not seem to work on the client side? I would have thought that the actual computer that the VR headset is connected to would be the server. Thanks again!
