External Monitor display issue when closing the lid of laptop

Question

Has anyone experienced this with an Acer or any other laptop?

I am working on a new Acer laptop (1810T) which I almost alway connect to an external monitor with a VGA cable.

I have set graphic options to display only to the external monitor and I would like to close the lid of the laptop, when I am working at my desk. In the power settings, I have set it so when i close the lid, the computer should "do nothing".

When connected to the external monitor I am able to view the display fine if the the laptop lid is open. However, whenever I do close the lid, the display on the external monitor continuously cuts in and out about every 2 or 3 seconds. I have seen other posts where the display simply shuts off, but I am getting constant (though irregular) flashes of the display, so I believe this is a different issue.

Any thoughts would be appreciated.

Solution 1

I have the same issue sometimes (sometimes at startup), even in dual display configuration. The external monitor would turn on and off at 1 or 2 seconds period.

Shutting off and on the monitor itself solves the problem for me, have you tried that?

Solution 2

The shortcut WIN+P will help you to switch back the work to monitor as a normal user even after closing the laptop lid.

I second the dual displays.
