Full screen Youtube videos in Safari go to black screen

[shinji]

I'm having an issue where when Youtube videos are viewed full screen in Safari, the entire screen goes black. If I move my mouse, it'll show the video again...but after a few seconds, it goes back to a black screen.

Any ideas? 2018 Mac Mini running Mojave.

Go into the "Display" properties for your monitor and do a calibration. I just took all of the defaults and "Nexted" through the whole thing. Afterwards, try the videos.

Don't know why/how but, that's what worked for me.

Ok, weird enough that worked for me the first time I tried to play a fullscreen video. The next time, it reverted back to the same behavior.

Hmmm? Did you check the "Show profiles for this display only" box and is the right one still highlighted?

That's what worked in my case...sadly I'm at the limit of my knowledge on this issue

Fixes it for YouTube, not Netflix, however. Gosh is it annoying.

I'd use Chrome, but I'm pretty sure Chrome doesn't support the same high bandwidth rates as Safari.

Today's Mojave update appears to have fixed this issue.
