Streaming a Game on the XP S

i had some issues with the framework where my usb hubs that also had video output on them, sometimes we'd just disconnect. So i thought, all right, i'm going to solve this by buying a thunderbolt dock. How i thought that would fix it, i don't know. I've got a us pc thing for 25 quid that works perfectly well. Except when you umplug USB devices, sometimes it just goes away and you lose your display. But that's kind of expected with a cheapUSB dog, right? Say, it must be my set up that's the problem, right?
