Switch to a different input and then back to the first input.
l
Make sure any connected computers are on and not in an energy savings mode.
l
Restart the display and any connected computers.

See Turning off, turning on, and resetting the display on page 54.
Set any connected computers' resolution and refresh rate to values that the display
l
supports.
See Setting a connected computer's resolution and refresh rate on page 41.
Replace the video cables that connect any computers to the display to determine if
l
the issue is with the cables.
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
computer. If it's not there, the computer may not support Display Port Alternate
Mode video via USB Type-C.
Make sure the cable used with the USB Type-C receptacle supports Super Speed
l
(5Gbps) USB. Look for the Super Speed USB logo on the cable. If the cable doesn't
have the Super Speed USB logo, it may not have the internal wiring necessary to
carry Display Port Alternate Mode video data.

may be eligible for a replacement.
Be aware that if two or more displays are mounted side-by-side, there could be
l
minor differences in colors across the displays. This issue is not unique to SMART
products.
If the screen is completely lacking one color on the screen or the color problems
l
occur on the Home screen, see Contacting your reseller for additional support on
page 70.
If you're using a VGA video input, use a different cable or connect a different source
l
to see if the issue is with the cable or input source.
Adjust the display's color settings, or reset them to the factory defaults.
