A:AnswerThis is simply a monitor.
You CAN plug in your computer or XBox into it for some great gameplay, but - as a standalone - it is simply a monitor.
A:AnswerYes it comes with a stand.
Height from the desk is about min 2.5in and max 8in.
It does not allow for rotation but does allow tilting forward or back.
There is an ever so slight bit of play when attaching the mount that allows for some unevenness. It is bothersome enough that I decided to upgrade to monitor arms but would be fine for most.
