Theres 2 different video resolutions. 4:3 and 16:9 (Widescreen).
Most videos are 4:3, like the tv broadcast in singapore. Movies are
often in 16:9. If a 16:9 video is played on a 4:3 television, of
course you’ll see 2 black lines. But it the black lines appear on a
widescreen television, you just have to change the screen format
setting.
