Windows 10: External VGA Monitor detected but displays black screen

I'm having a problem with an external VGA monitor connected to my Win10 home PC. When I plug in the monitor (to VGA port), it is detected but the display blinks on and goes black immediately. I have to unplug and re-plug up to 12 times and finally the monitor comes on and stays on until the power option tells the monitors to go blank. Then I have to do the whole unplug/re-plug thing again to get it to display the screen. Seems to me it's a driver problem. I uninstalled the Monitor drivers (not the Display Driver). When the device is detected, two instances of "Generic PnP Monitor" drivers are installed. An alternative driver would be the AL1916w driver but I'm not sure how to install it. And this may not be the solution anyway.

Hi Sivaram,

Thank you for writing to Microsoft Community Forums.

1. Since when are you facing this issue?
   

This issue might be happening because of the faulty drivers. That’s the reason you are getting intermittent connection on external monitor.

However, you may try the below suggested steps.

Step 1: Try connecting on a different monitor and check if the issue still persists.

Step 2: Try using a different VGA cable to connect with external monitor and check the status of the issue.

Step 3: Update display driver adapters

You may refer the article
Update drivers in Windows 10 and check the status of the issue.

Step 4: Check for an updated Video driver on the

Acer drivers and Manuals page.

For more information you may also refer

Hope it helps.
