hi my Acer monitor AL1603W shows a input not supported message when i turn my computer on. it has been working fine before today.


My name is Deepa and I work for the Social Media and Community Team at Dell. I would suggest you to please reseat the monitor cable (for example if it is connected via VGA / HDMI cable please unplug the cable and plug it back in). You can also try to check the input device selected is corrected or not. You can also refer to this link for support on Acer monitor issues:-


For further help please reply.

Thanks and Regards
