No picture while streaming?

With Twitch and other video platforms I have no picture but sound, why can that be? (Laptop, Windows 10, Google Chrome)

Have you connected several screens?

No

Check if you have created virtual screens

So the page is already displayed, only directly the video or the stream is not

Uh, what

Have you switched any interfaces in between (image processing, etc.)?

No

Try it with another browser, maybe it's because of that

So it was like this for 1 year, that's only since today

Then probably some change has occurred. Think about whether you have changed anything

I really did not do anything

Has Chrome updated? Is 2 years old, but maybe the problem is still up to date with updates: https://galaxy-tipps.de/google-chrome-video-schwarz-kein-bild-aber-ton-bei-youtube/

In the meantime the problem has gone away by itself

These are the best problems that solve themselves
