Solutions
Minor differences in colors across displays are common. This issue is not unique
l
to SMART products.
If you're using a VGA video input, use a different cable or connect a different
l
source to see if the issue is with the cable or input source.
Make sure the cable is not longer than the maximum specified in the display's
l
specifications.
Make sure the cable is securely connected to the video connectors on the
l
display and the computer.
If the video connection uses and extender or goes through a wall socket, try
l
connecting the display and computer directly.
Perform a factory reset.
l
See Factory Reset on page 57.
Take a photograph of the screen that shows the issue with color and send it to
l
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.
Adjust the connected computers' video settings, particularly zoom, crop,
l
underscan and overscan.
See the computer's operating system documentation.
If the computer's desktop is entirely black, change it to gray or a different color.
l
If the computer's desktop is extended across multiple screens, duplicate the
l
desktop across the screens or use the display as the only screen.
Make sure the cable is not longer than the maximum specified in the display's
l
specifications.
Make sure the cable is securely connected to the video connectors on the
l
display and the computer.
If the video connection uses and extender or goes through a wall socket, try
l

the issue is with the cable.
If the video source is HDCP-protected, make sure it's connected to an HDMI port
l
that supports a compatible version of HDCP. The HDMI 3 port supports only
HDCP 1.4. Be sure to connect devices that use HDCP 2.2 to the HDMI 1 or HDMI
2 port.
Make sure the computer is the currently selected input.
