Display Port had an HDMI before
Since it is only a "Gsync compatible" display and not a true Gysnc display, you will have a difference in quality. My guess is there are timing issues that are not addressed with that monitor, and since it's not on the G-SYNC compatible list (Check here to see the full list of monitors, your HF version is not there), it's not a certified good monitor for use with Gsync. I'd honestly turn it off if I were you.
