UGOOS 9AM PRO DV GREY BARS
I’ve noticed on my LG OLED G5 with the Ugoos 9AM PRO that the black bars in Dolby Vision aren’t black, but more like a grey tone. It’s the same for every Movie (DB Profile 8) and a Video I have. SDR and HDR10 are unaffected. I will attach 2 pictures.
1st picture with grey bars will be am9 pro, 2nd picture with black bars will be fire stick.
Both films are Dolby vision, I already tried changing players and some setting but nothing helps.
On the Fire-stick 4k max everything is all right.
