Release the menu button (check if anything is leaning on it), and press and hold the menu button again until the message disappears (app. 10 seconds). If this doesn´t work, the button may be stuck, or there´s a problem with the hardware.
On the monitor, press Menu, and select Factory Reset.
If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.
Connect the monitor to another computer. If the line appears when the monitor is connected to the second computer, the monitor might be damaged or defective.Otherwise, the video card and driver is causing the problem from the computer.
let me know if this resolved ur issue.. regards,guru
have you tried going to menu and setting back to factory defaults? also, disconnect power cable and leave unplugged for 1 minute. Plug back in then see if problem is still there. Otherwise, something is wrong with the monitor that will need serviced or exchanged.
It's possible that the ACPI (Advanced Configuration and Power Management Interface) is not enabled in the bios.
To access the bios either press F2 or DEL, depending on the motherboard(usually tells you on the initial boot screen), then look for a line that reads 'Power Management Setup' or similair and press ENTER.
When into the menu check to see if ACPI is reading enabled,
if not press the right arrow on your keyboard then either press PAGE UP or PAGE DOWN or + or - on the keyboard.
Press 'ESC' then it will ask if you if you want to save changes, press'Y'.
That should sort it.
