Have the TV for a week now and am completely satisfied. At first I was also surprised that he has only 50Hz because I actually thought that all modern televisions have at least 100Hz automatically in this price range. Have therefore not respected it when buying. Nevertheless, I can say that until now I do not miss the 100Hz. Yesterday a football World Cup game looked and am very satisfied with the picture quality. I have no direct comparison with a 100Hz TV, and thus it may be natural that it looks just a tad bit on such a better and sharper, but a disturbing ghosting I could not discover in spite 50Hz and the focus was really good especially in HD. Irregularities in the illumination I could in normal operation so far also not discover. Special Tests I have in this regard, however, not carried out. The TV has a variety of settings, with which you can adjust picture and sound according to his own taste. I got so definitely a great image about. The sound is for my "Ottonormalvebrauchergehör" good, although it is always said that for televisions with LED backlight, due to the small thickness, the sound is not likely to be as good. Again, however, I have no direct comparison. The picture quality and a Blue-Ray is excellent. I have bought the same for Sony BDP-S370 to. The practical thing is that can be controlled both devices with the same remote control, which works very well. Watch DVDs with these devices Kombie also very good. The remote control is by design nichs fancy but it is easy to operate. The menu is concise, but differs probably no different from other Sony. The TV hanging with me at the Internet router, so I can also access some Internet content. However, the offer is limited to films (among other things, YouTube) and music. Some offers are plus costs. Software updates are carried out automatically and downloaded to instructions either via the antenna cable or the Internet. The instructions that come with paper is more of a Quick Start Guide. If you want to know more accurate you have to go through the electronic "i-Manual" of the TV. Unfortunately, described there explanations of each function are often very superficial. Also I would personally prefer a manual in paper form. The "i-Manual" might be as an addition to very useful but alone it is rather disturbing. The price is for an Edge LED TV really good, so I can recommend it highly enough. Those who can not do without 100Hz must rely on the Sony KDL-40EX705, but which is again more expensive then probably.
