The software is the current (119.49, was 03.29.2015). With the performance and the function I have no problems, only I have rarely any HDMI repeatedly to select the TV signal reproduces. Even Android looks good, no problems. Google with voice commands, YouTube, Browser etc. work convincingly well.
The picture I have something worked in the settings, so that it cuts a fine figure in all situations.
The image is downright bombastic and I sit 3,5m away from it. Especially the 3D picture via Blu-ray is incredibly sharp and detailed, which really is a unique feature of the Premium device. Although I was not a fan of 3D, now I am.
The 2D Blu-ray image is spotless.
4K I have not play, but with full HD image is already perfect.
The HD image of eg Sky's fine, but I notice here already slow that I could sit a bit further away, but it's okay.
The SD signals are sufficient as with all large HD TVs appropriate, but no more.
The 2D to 3D scaling works quite well, that image is nice, but the function is unnecessary.
The contrast is mistaken, one might think the TV has a Galaxy S screen in large, black is black and white is white, local dimming works very well.
The sound is contemporary class, this I need not say much, the 3D surround sound mode is however EHR immature.
The back of the very high-quality remote control is a keyboard that facilitates typing.
The gesture control is also immature.
The Ambilight is impeccable, the modes and match vivid are my favorites, in game on the TV in black set the Ambilight at locations corresponding out, very nice.
I highly recommend this device, the price is certainly not any tastes, but that everyone must decide for themselves.
