Thank you for posting on the HP Support Community.

• Have you made any hardware/software changes?
• Have you tried connecting the monitor on a different screen?

To fix incorrect colours, 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 discoloured, 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 colours are incorrect when the display is connected to the second computer, the display might be damaged or defective.

6. Service the display.HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
