the gaming machine can handle all that, as i currently use it with a steam link (mentioned elsewhere) which means it's scaled from 4k/2k to 1080p or 720p depending on what TV i'm on. I'm sure i can run 4k (with a dummy hdmi dongle as i don't have a 4k plugged in to this pc anymore) with moonlight/sunlight/etc because i can do it with remote desktop!
