A:AnswerFreesync works over HDMI, but an NVidia card only does G-Sync over Displayport. If you're using an HDMI cable, you might not see the option to enable G-Sync.

A:AnswerSuper speed USB is USB 3.0. This monitor has a USB 3.0 hub built in. Connect the cable that comes with it to the PC, then into the port on the back. This allows you to use any of the 4 USB 3.0 ports on the monitor as a USB hub. (2 on the bottom, 2 on the left side)
A:AnswerThere’s two HDMI ports on the back. Just plug in one from your xbox and you’re good to go. As far as color calibration, that depends on your preference.
