have you tried connecting this monitor with some other computer
Just try that once and let me know.

Hi there reinstall the display driver & then give a look. If you face same problem then its may problem with your display driver or in the monitor.

The screen is bad, verticle lines, red or pink hue etc. is indicative of a bad screen or there maybe a problem with the data cable you are using to attach to the computer. Try another cable first, if the problem persists, the lcd panel is failing.

hey try to put your monitor on other pc, if its work then its not broken.

The native resolution for the Acer AL2216W is 1600X1200. It is acting correctly for the resolution you have set it to.

LOOKS LIKE A BURN SOLDER !! , open the monitor , check the PC BOARD around the transformer area , look for burn spot or cold solder , RE solder it , try again , hope this helps please rate solution and thanks AJ
