I am using 4K HDR TV. I am not able to get the "3840x2160p 60Hz" mode by toggling the "TV mode" button.
I can get only upto 3840x2160p 30Hz. To get 2160p 60Hz I have to go to Settings>Display and change it there. It accepts.
And once done the "TV Mode" button/ toggle does not work any more. It will only display "3840x2160p 60Hz".
So to set 1080p 60Hz etc., I have to go back to Settings>Display and change.
Any idea why this is so?
