I have a question why when I watch them on my tv it cuts the left and right side of the picture. Any suggestions how to fix this
Most TV do overscan and sightly zoomin the picture (to avoid seeing garbage border often present in HDTV broadcast)
It’s probably under your TV advance setting and may have different name.
On mine it’s call HD size. and the option is only for 1080p, overscan on 720p on my set is forced unfortunately.
