Twitch error image on the TV?

Hey just wanted to watch a Twitch stream on my TV which has always worked so far. But now I only hear the stream and there's some disturbance in the picture. Does anyone know how I can correct this?

Make the resolution lower!

It seems that either the screen or an internet is not keeping up.

But unfortunately I don't have anything, as I said the sound is quite normal and before that it always worked

Turn the monitor off and on again.

Does a stream also look like this with other streams?

As I said, it could be because the monitor is not designed to provide too high a resolution.
