Hello! I'm new to the forum but have been downloading firmwares here for couple of years. After updating to the newest firmware 2.1.4, I found there were back bars at the top and bottom of my TV screen when playing 16:9 content, which is supposed to fill the whole screen. I didn't notice that until recently because the black bars are too narrow to make any discernible distortions to the image, and certainly I wouldn't see that watching movies because there are already huge black bars in the first place...I tried everything I could find in the UI (adjust display area, change aspect ratio, etc) but nothing seems to work. I even rolled the firmware back as far as to 2.0.4 and the problem persisted (I didn't do complete reset when installing older firmwares, so old settings were carried over). What makes it even stranger is the UI of Q5 pro fills the whole screen and 4:3 content reaches to the very top and bottom of screen. The only issue is with TV shows with 16:9 aspect ratio. Anyone could help? Thanks a lot!
