Windows 10: When I connect my laptop to my monitor, only my monitor is displayed

Hi! When I connect my personal laptop to my monitor, only the monitor will display the screen. I don't know what could be causing this as everything worked just fine a week ago. I have had my work laptop connected to the monitor for a couple months though. Is there something I need to do from my work laptop to undo this for my personal laptop?

Help is very appreciated.


Thank you!

Connect laptop to monitor

Hi,

Thank you for posting in Microsoft forum.

Regarding your query on how to connect your laptop to your monitor, we suggest to contact your manufacturer. Maybe one of the issue is your display adapter because you cannot connect to your monitor.

We look forward to your response.

No display on laptop's external monitor-Monitor recognized but blank

After the recent Windows 10 update, my wife's laptop no longer displays on the external monitor. All was well before the update.

I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

Device manager reports that I have the latest display driver installed.

I would appreciate any and all suggestions.
