Yeah I just want to make sure I have it set properly so when I watch movies with different aspect ratios that I'm getting the ratio that the movie needs to be in. Yesterday I was watching Wonder Woman 84 in 4k and its in 2.39.1 and 1.90.1. So to my understanding the imax shots should be full screen no? I had a very slight black bar top and bottom during the imax scenes I believe (will check again this morning). So many aspect ratios! LolI think its on by default in every mode(game,etc).U get 1 to 1 pixel and u disable overscan with this setting on i think(not sure) so u get a sharper and a better image thats why it is defaulted on..But really not sure,maybe someone wll enlighten us.
