To fix incorrect colors, complete the following steps:
1. Check the video cable connections and make sure the connection is not loose. Tighten the
connection screws if the connector is loose.
2. Press the Auto or Autoselect button on the display.
3. Press Menu, and select Factory Reset. If the screen is still discolored, continue to the next step.
4. If the display has more than one type of connection available such as VGA, DVI, or HDMI, try a
different type of connection.
5. If possible, connect the display to another computer. If the colors are incorrect when the display
is connected to the second computer, the display might be damaged or defective.
6. Service the display.

Whenever these types of messages appear on the screen, the display cannot detect or set up the video
signal.
To prevent the errors from occurring, make sure a compatible video signal is being sent from the
computer (or other video player). Make sure the computer is not in a sleep mode, check the cable
connections, restart the display, and make sure the computer is using a compatible display mode. For
more information, see HP support document Flat Panel Monitor Displays Message About No Signal,

mode. Power saving modes can also occur if the display has not received a video signal for a long time.
