Screens go black on the website?

Hi, when I go out from a website (Spotify, Netflix), my screens briefly go black and then come on again as if the HDMI cables were briefly disconnected. I have that on all desktop PCs from me. This is not the case with my laptop, where an internal and external GPU is installed. Why is that?

At what refresh rate does your monitor run and do you possibly have full screen mode on browsers?
It would be new to me that there's this problem with browsers, but earlier, when I was in HDMI in certain games and went to the desktop, I always had a short black picture.

Yes, exactly the same if you e.g. GTAV starts

Maybe try another HDMI cable or as I said: At what Hertz rate does your monitor run and are you in full-screen mode with browsers?

No, not necessarily. Sometimes on Netflix. Nothing else has to be said: With the new Edge Chromium Browser, only the screen on which the browser is open briefly turns black, with Chrome both screens. My monitor runs at 60Hz
