Horny treat is the universal remote control, can be controlled with the device all connected. Amazon Prime video works in super resolution (depending on bandwidth DSL), also YouTube and other apps run smoothly, it is worth a Bluetooth mouse or keyboard for input, especially when pure surfing, a search input with the remote control is troublesome.
Headphones are to be binding only on cable, unfortunately provided no Bluetooth connection that I find really bad.
3D is top notch, have me as many others regarded in the market, especially with the LG polarization and newer models of Samsung, this is here as a 55er really properly in image and depth, I see no flicker when the shutter glasses. However, it is quite on the 3D material, since there is very beautiful junk in the recording. Schön is already times that a BlueRay 3D full Shuttered resolution is on my UE55H6270. No 3D glasses this would actually be a no-go, but the SSG-5100's for 15 euros each in a double, so not really an obstacle.
I could compare directly to a 3D Blueray DVD UE65H6470 and one in the market and could not find that the 6470 was better in some representation. Make the bit more comfort in 6470 for me the current price difference is not compensated for, which is why I would always tend in offers under 600 euros for a 55 to 6270. The advertised 400Hz during 6470 or the 200Hz in 6270 I do not see what I value neither good nor bad, if I do not recognize it, I do not need it.
All of our Samsung phones and tablets functions of course immediately with the TV and the APP "Samsung SmartView 2.0" (in PlayStore) on the Note 10.1 even gets the TV screen onto the tablet and I'll take it for example in the kitchen, even switch and control of the Sky receiver and DVD player function from the other rooms over the WLAN.
All in all a full purchase recommendation with a corresponding offer.
