eg. I need to dismiss a dialog that is invisible over remote play, or it won't finish logging in until I close a "finish setting up your windows install" screen.
Win+R mstsc.exe and put in the gaming machine's name or IP and follow the instructions, checking all "remember this" boxes (there's 2, three if you count the certificate).
RDP won't let you play games but it is functionally identical to sitting at the machine itself.
Someone else probably has alternatives (moonlight? bazzite? gopro and a soviet-era robotic arm (it only leaks a bit when it's hot outside.))
I run a Windows VM on one of my servers for some gaming because I don't run Window's otherwise, and with Sunshine on the VM, I can play with moonlight from my TV, laptop, desktop, phone, ROG Ally (Bazzite), tablet, basically anything that can support Moonlight.
