Troubleshooting steps
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.
l
Tap the Home button
remote control to open the Home screen. If it appears correctly, the issue is with the
video input.
Take a photograph of the screen and send it to SMART support. If SMART support
l
determines that the issue is with the screen and the display is under warranty, you
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 48.
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 any connected computers' video settings, particularly zoom, crop, and
l
underscan.
See the computer's operating system documentation.
If you're using a VGA video input and any connected computers' desktops are
l
entirely black, change them to dark gray or a different color.
If any connected computers' desktops are extended across multiple screens,
l
duplicate the desktops across the screens or set the display as the only screen.
Adjust any connected computers' video settings, particularly overscan.
l
See the computer's operating system documentation.
Make sure the connected computer's video connector is configured to output a
l
supported video signal. See No video display output from a laptop.
See Image persistence or burn in on LCD displays.
