Troubleshooting steps

l
Restart the display and any connected computers.
l
Set any connected computers' resolution and refresh rate to values that the display

l
issue is with the cables.
Make sure a replacement cable meets the required specifications.
See Using recommended cables on page 51.
Make sure that the computer supports Display Port Alternate Mode video via USB
l
Type-C. Look for the Display Port logo beside the USB Type-C receptacle on the

video via USB Type-C.
Make sure the cable used with the USB Type-C receptacle supports Super Speed
