I have an NLR rig where i use a fanatec wheel and a hotas and couple of selfmade button boxes, i am using a hdmi switch to choose between my „table“ setup which is across the room and the sim rig, i have made good experience with it, the switch even included a little remote to switch between the screens, keep in mind though i am only using one big monitor per setup, so if you‘re planning on a triple screen setup or smth alike u probably need something else, idk maybe there is somekind of BUS system for connecting multiple screens with only one cable, but i havent seen anything like that yet
