Windows 10: Monitors turned off suddenly

I use a laptop with two connected monitors. This system worked without any problems for a few years. Currently I am facing a random issue. All of a sudden my two monitors went dark and I saw all the apps and files on the laptop screen. I restart the system and the move all the apps and files to their primary location. Why did it happen?

2nd Monitor suddenly not working

Hi Michael,

If you recently updated from one version of Windows to another, it's possible that the current driver is for the previous version of Windows. For us to troubleshoot your monitor issue, we suggest performing these steps:

• Run the troubleshooter for devices and hardware. The troubleshooter will perform a diagnostic process on your system that will check and resolve issues related to
  using your device.
• Update your monitor and display driver. To update a driver, refer to this
  link. If Windows doesn't find a new driver, you can try checking for one on your device manufacturer's website.
  

Get back to us with the result.

using a monitor to extend my screen

Hi Lou,

There are several possible reasons why your LCD monitor suddenly stopped working. It could be that the graphic driver is outdated or could be the cable used is already damaged.

For us to isolate this problem, we would like to ask the following information:

• Were there any changes made on your computer prior to the issue?
• Have you installed any updates?

In the meantime, please try the following suggestions and see if your laptop will detect the LCD monitor:

• Update the graphic card driver. Check out Update drivers in Windows 10 for the steps.
• Use another cable. Try using another VGA cable to connect the LCD monitor to the laptop.
• Connect the LCD monitor to another computer. To help us isolate the issue, try connecting the LCD monitor to a different computer.

Please let us know how it goes. We're looking forward to hearing from you.

Regards.
