Also, for those new,
Banding will mostly affect your viewing of pans of largely solid color images. For example, watching a football game, or an ice hockey game, or an underwater scene or a blue sky scene.
I don't know why it bothers my brain alot, but it does. I guess my brain gets thrown off when it see the image moving, but the darker streaks stay stationary. Hopefully, most newer sets don't have it. My old Westinghouse had it. My new Toshiba RF350 does not.
