LG LED TVs support a wide range of audio, video and digital image formats. Whether or not a specific file format is supported shouldn't be an issue unless you are trying to load files directly to the TV using its USB port. The supported USB formats make it possible for you to connect a USB device with various media on it to the TVs USB input, and view or listen to the supported media.
Aspect Ratios and Zoom
LG LED TVs offer a variety of picture formats, also known as aspect ratios. The 16:9 format displays the picture in a widescreen format while the 4:3 format displays the picture in a standard resolution; the Just Scan reduces the overall size of the native image by 1 percent to 2 percent so you can see the full image; the Zoom format zooms in on the center of the picture, cropping the outer edges; the Set By Program format displays the picture in its native resolution; and Cinema Zoom increases the size of the picture proportional to the screen.
