Hi. I've been wanting to play late nights but my parents won't let me. I have planned to connect another monitor to my room by buying a 20m hdmi cable, I will connect that to my cpu and work its way up to my room. But there's a problem, I don't know if how im gonna connect my mouse and keyboard from downstairs, is there like an extension usb hub that i can connect to my pc downstairs so i can use my desktop even when im away from my cpu?
