One of the many issues that Windows 10 version 2004 faced upon launch is where external displays went black all of a sudden. This was known as the black screen bug.
This particular problem caused an external screen to go dark when using an Office application. Meaning, while it was not a particularly widespread issue that many users came across, it did create problems for those using the productivity suite on external monitors.
Since the major use of external displays is to boost productivity, an issue like this creeping up meant that it was critical for the affected uses to get a fix as fast as possible. As far as issues that needed attention go, this one was right up there at the top.
And as we can imagine, this problem took quite a while to fix.
The software titan has only managed to get around it proper now, and explains in a recent advisory that the whole things has been fixed.
“If you have a device running Windows 10 version 2004 with a built-in screen (such as a laptop or tablet) and a connected external display set to Duplicate your primary screen, you might see both monitors flicker and the external monitor go black if you try to draw using an Office app (such as Word). This can also happen with some other apps capable of drawing, such as Whiteboard. If you check in Device Manager, your graphics controller will have a warning icon next to it (a yellow triangle with an exclamation mark in it).”
All you need to do is just install the latest cumulative update for Windows 10 version 2004.
The one you specifically need is KB4577063, which Microsoft published as a preview on October 1. The newer cumulative updates will also do the trick, as they include all the previously released patches for the OS.
On the other hand, deploying this cumulative update could lead to other issues, like the certificate bug that the software titan has already acknowledged.
Bugs, bugs, everywhere!
