First It hums and buzzes sometimes but audible (from 3 feet at low volume) when we look on it with bright images and impressions. But I also read in forums that it is less for some more in others. Is also well on their own perception, my wife and my kids have not noticed.
Second The black levels could be better. Is ok, but for movies with lots of dark scenes, but it disturbs a little, because the black a bit milky, without details, and therefore acts like a flat surface. Samsung UN46EH6000
Optics and processing
The TV is that I have now just say, top handles. I can make up any loose or rattling parts. The border is, in comparison with other devices, not extravagant narrow. But that does nothing, because the rim and the foot of the Samsung TV's glass is taken into the device and thus gives an optically high-quality printout. At the bottom of the foot, Samsung has processed rubber nubs that prevent the TV from slipping and protect the bearing surface is. The TV is, when set up to rotate approximately 45 degrees, which I think is very practical. A bracket to hang the TV on the wall, unfortunately, are not included and must be purchased separately.
Now I come to the only negative point of the optics. I have the TV in my bedroom and living area are available and after just one day after cleaning the TV's you can already clearly see the black dust deposits on glass surfaces. This is not tragic, and perhaps not a criticism of the product, but rather on my space. Still, I wanted to mention this briefly.
