Very confusing problem:
I can watch the live streaming on this website (https://www.la7.it/dirette-tv) on my MacBook Pro.
However, if I connect the computer to my LG OLED TV, the video window goes completely black (both on the laptop screen and the TV screen), see screenshot.
This happens both on Safari and Chrome, and only for the live streaming video in that website (non-live videos on the same website work perfectly, and live videos from other sources as youtube also work fine).
This started to happen only recently, while it was working a few months back with same laptop and same TV.
Additionally, I can connect a Windows laptop to the TV and see the live streaming without any problem.
Does anyone have any idea of what's going on, and how to solve the problem? I am very confused.
