Design: To design can not say much: Display in a plastic "picture frame" plugged. Very high quality does not affect the. Workmanship I could find none.
Installation: I am trying new purchases first ever to do without the manual. The connection to the router was quick to set up, no problem. Not quite as intuitive is done the transmitter installation. So the tuner not initially affected all stations, this had to be set in a menu item separately. Also, I could not find anything that the detection of encrypted channels excludes. The station sorting is indeed solved time consuming, but logical.
Operation: Easy, particularly the Smart Touch remote control as a complement to traditional remote control is very convenient for a bit of familiarization. Excited I am about the interaction of Internet, TV and electronic program guide. Although I unfortunately there is only one 6000 kbit / s DSL line available, also let you watch HD content easily and without any lag or dropouts. Toll. Changing stations and dealing in the libraries or the Apps is very fluid and fast.
Image: About the image I was initially disappointed for several reasons. However, I have the menu item "Extended setting" overlooked, also I oriented myself to setting proposals from the Internet Forum [...]. So I was able to "cobble together" an optimal TV viewing. The whole process to achieve a very good picture, but I think a bit too complicated. Excellent is now the picture quality (both HD and SD) from the Internet. Top are also transmitted in HD TV channels. The SD quality of the TV is decent, but worse than that of the Internet.
Sound: For me absolutely unacceptable. I think that would go a lot more today with a corresponding will. I am thinking only of the inexpensive mini bass cubes from the grocery store, or even at the sound of phones like the HTC One M8 or Sony Xperia Z2. Manufacturers like Samsung probably go on the assumption that the devices are already connected to the hi-fi system or speakers. The latter I have done.
Not yet I tested 3D and recording via USB.
Conclusion: Overall, a good device with ultimately very few deficits and a very good price-performance ratio. Therefore 4 of 5 points.
