Since yesterday a "whitelist approach" was implemented for refresh rate switching - you need to properly select the modes you want to allow switching to.

 so from today no longer recognizes automatically, I have to set it manually with "the white list" right?
hen I don't understand the white list, I can always adjust the resolution before watching the movie in screen resolution no?

EDIT :

After several tests made with the "white list" I must say it is a brilliant thing!
and it works perfect, everything!

I wanted to thank the team and the forum for support, I always forget to do it!
