Chrome video stuttering on second monitor

Hi everyone, I formatted my desktop computer a few days ago and I noticed this.
If I watch a video from YouTube on my second monitor using "Google Chrome" the video has micro jerks, at first I thought it was the fault of buffering but this is not the case.
Usually on the second monitor I watch some videos from YouTube and on the main monitor I surf the internet and I have noticed that if a video from YouTube is running on the second monitor, a video starts on the first monitor again via "Google Chrome" browsers and for example a video on Instagram the video on the second monitor gets worse, it starts to have more micro jerks, it freezes and the wheel comes out even if the buffering is much further ahead.
While if I try to watch a video always with Google Chrome and on the first monitor I use another browser it's fine.
I don't understand, if I use Chrome on both monitors there is this "video blocking" while if I use two different browsers it's fine.
In Chrome settings the option "Use graphics acceleration when available" is activated.
Some advice ?
the drivers are obviously updated

Sorry no one has answered, I just saw your post.
