Symptom Troubleshooting steps

There are bright spots on the screen.

Tap the Home button below the screen or press the Home button on the

remote control to open the Home screen. If it appears correctly, the issue is with the

video input.

l Take a photograph of the screen and send it to SMART support. If SMART support

determines that the issue is with the screen and the display is under warranty, you may

be eligible for a replacement.

Colors don’t appear correctly. l Be aware that if two or more displays are mounted side-by-side, there could be minor

differences in colors across the displays. This issue is not unique to SMART products.

l If the screen is completely lacking one color on the screen or the color problems occur

on the Home screen, see Contacting your reseller for additional support on page50.

l If you’re using a VGA video input, use a different cable or connect a different source to

see if the issue is with the cable or input source.

The image is cut off or shifted to the

left or right.

l Adjust any connected computers’ video settings, particularly zoom, crop, and

underscan.

See the computer’s operating system documentation.

l If any connected computers’ desktops are entirely black, change them to dark gray or a

different color.

l If any connected computers’ desktops are extended across multiple screens, duplicate

the desktops across the screens or set the display as the only screen.

The image doesn’t fill the entire

screen.

l Adjust any connected computers’ video settings, particularly overscan.

See the computer’s operating system documentation.

l Make sure the connected computer’s video connector is configured to output a

supported video signal. See No video display output from a laptop.

A persistent image appears on the

display.

See Image persistence or burn in on LCD displays.
