Reference Information
■ SD/HD broadcasts and the TV's display capability are related
1. A digital broadcast should be transmitted in wide screen (an aspect ratio of 16:9) HD. If the broadcasting station converts a
conventional program created in normal screen (aspect ratio of 4:3) into a digital signal and broadcasts the signal, the left and
right of the picture will not be displayed.
This symptom also appears in other manufacturer's TV's. The three appliance companies are trying to resolve the problem
through the Ministry of Information and Communication.
