Aspect Ratio Explained

The TV is a widescreen TV, but most TV programs are still broadcasting in a square format, therefore the
TV is offering multiple ways of viewing videos. There are mainly two types of signal format, Full (16:9
format), Normal (4:3 format), while others offer a novelty ways to view the TV. Simply use the ASPECT
button on the TV's remote control to cycle between the multiple modes.
1. FULL
This mode will stretch the picture to a widescreen ratio. If you have a perfect 16:9 ratio picture you will
not see any black bars. If you are watching a widescreen movie in 1.85:1 or 2.35:1 ratio, you will still
get black bars on the top and bottom of the screen. If you use this mode on 4:3 pictures they will be
stretched and distorted horizontally.
2. NORMAL
Most analog TV channels have 4:3 signal formats. If the original 4:3 aspect ratio (1.33:1 source) is
preserved, black bars are added to the left and right of the display image. This aspect keeps that
aspect ratio and shows you the black bars on the side.
