“If you’re using a Windows 10 2004 device (notebook or tablet) with your own screen, it’s likely that the following will happen when you connect an external monitor and choose to copy the display mode — the display flashes, or the screen bleeds,” Microsoft wrote.

According to many users, this happens occasionally when drawing with Office applications, such as Word. There are other drawing-supporting applications, such as whiteboards.

If device manager is turned on, you’ll see an exclamation point with a yellow triangle next to the graphics controller (warning the device of an abnormal function).

In fact, Microsoft fixed the issue in last month’s KB4577063 (non-security-related cumulative update preview), but only as a recommended update at the time.

Users who have an external monitor connected but are unable to install the KB4577063 update can try to resolve the issue by restarting the device. However, Microsoft recommends that you use the drawing application carefully, which may cause the display function to fail.
