We are more than satisfied with this TV. Even without 4k offers is worth the purchase of this TV. The picture is clearly noticeably better than with our previous television - and that was not worse :). Details - especially in landscapes incredibly sharp! The sound is OK - we have connected nevertheless a Soundbar LG and now the viewing experience is perfect. 3 D we tested - super! The built-in receiver, we do not use - we tried it - but there were problems because we have 4 LNB's and it was virtually impossible to sort the channels. Our Panasonic receiver of LG works well. All - we would buy this TV again.
