I need to tone say this according to the thin construction despite the Testing of all settings at least to us - is of course feeling thing - not satisfied! Therefore we have powered speakers - Creative GigaWorks T40 II speaker - added taken that let the sound finally pleasant effect on us. The external speaker does not want to just use the optical output can be connected to the headphone jack. However, because you can not govern with the remote control in the volume this connection, we have our external receiver, which we use as before and finally we can adjust the volume.
Supplement: It can also be regulated via the headphone output, see comments. Special thanks for the hint! :-)))
The manual / user manual is very minimized so that it does not even all connections are shown. So you can find back some Chinchbuchsen for which no information exists. The other ports are not mentioned in the paper manual. The technical data are minimized so that they have no significance. Since LG should still leave with something. Even if we know how to help us, so not every customer is so technically proficient that he understands everything at the mere look.
However, I would recommend the TV and very forgiving clear 4 stars. It would become 5, if everything Top had described.
