Worked for me :)
Try to wake up the display
Many times it could happen that Windows 10 is just not detecting the display. Using your keyboard, you can use the Windows key + Ctrl + Shift + B keyboard shortcut to wake up your display.In the case that you're using a tablet, the process to wake up the display is a bit different, press the volume up and volume down buttons simultaneously three times.
