Solutions
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 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 the computer's desktop is entirely black, change it to dark gray or a different
l
color.
If the computer's background is extended across multiple screens, duplicate the
l
desktop across the screens or set the display as the only screen.
Adjust any connected computers' video settings, particularly overscan.
See the computer's operating system documentation.
See Image persistence or burn in on LCD displays.
See Referring to the SMART knowledge base for additional troubleshooting
