I had a problem with my ATV4K where HBOGO, CBS and CW would not display video. I click on a program, the video will flicker for a nanosecond, and then the screen will be blank while the sound continues.
After many attempts and errors, I have discovered that when the video on these apps is not played when Dolby Vision 4K is assembled with frame rate / range. When I turn the frame rate / range off, video works.
But I also discovered that I can't put this box into 4K SD, which many people recommend (with frame rate / range). When I try to set it to 4K SD, the screen turns black for many seconds before returning to DV4K.
Someone knows why this is? Can't be normal, right?
