The play movie files I enjoy. The viewing pictures and various video files is not as good. It can only be viewed in full screen or in (smaller) size. A stepped Size setting to play would be better.
An HDMI - connections there are no problems. A WD-Multimedia-Box, a video recorder and a notebook can be properly on LG 19LS350S use.
The picture is also very good, when the automatic setting is used. The sound is adequate.
The menu guidance is practical.
Unfortunately, there is a headphone port.
