Which port are you using on you Orion? Which port are you using on the XB3? Which version cable is it?
There have been several versions of HDMI and DP over the years and some of the older version cables don't support the newer version ports at full capabilities. They should still work, albeit at lower performance. For instance some won't do 4K at 60Hz...When connected try using the OSD on the monitor to change source ports, it may be the auto sensing isn't working right. Do you have a different machine to try the monitor with? We really need to pin things down to the Orion or the monitor.
