Brand new 53HS30. Used Avia to calibrate. When I popped in a movie with an AR of 2.35 there are additonal thin black bars along with the black bars from being in 16:9 mode. The 2.35 bars are not true black and definitely stand out. Also, black images in the movies: space scenes, credits, fades to black, are not true black. I then, with my own eye, lowered the "brightness" setting down about 7 notches. Now I have what appears to be true blacks and the 2.35 bars match evenly with the auto 16:9 bars. Is this ok to do? Technically my TV is not set up with Avia, but it looks better. Should I reset my brightness back to Avia? Is my TV malfunctioning and should the Avia brightness setting give me true blacks?
