My HP 22 er monitor keeps opening and closing. I've tried to follow these steps (from a previous forum topic) :
Disconnect the monitor’s power cord and the cable from the computer.
Please press and hold the power button of the computer for about 20 seconds to discharge static electrical charges.
Reconnect the power cord and check if the monitor goes blank or flickers without connecting it to the computer.
Then check if the issue gets resolved. If it continues, please try the steps.
Press the Auto or Autoselect button on the display.
Press Menu, and select Factory Reset.
If the display has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.
Set the video resolution on the computer to match the native resolution of the display. Find the native resolution for your display from the box the display came in, the Monitor User Guide, or product specifications.
I'm sadly unable to perform anything from the second round (starting "Press the Auto or Autoselect button on the display") as the monitor keeps opening and closing and the buttons don't seem to work.
