I had a 65” Samsung UN series TV and “upgraded” to this brand new 75” TU7000. The overall picture is super dark, even on dynamic. However I use my iPad a lot to mirror (airplay) to my tv. In this mode on this TV… it seems that Samsung decided for me that I can’t zoom or even adjust the aspect ration. I am worried it’s going to burn my screen. My old TV this worked fine on and filled the screen. On this one… I’m probably viewing 50” of TV. Anyone got a fix for this?
