The most jaw-dropping moment of our time with the Sony KD-84X9005 came when Sony demoed the 3D trailer for The Amazing Spiderman. The thing is, the TV uses passive 3D tech rather than the usual (for Sony) active system. But because the TV has a 4K resolution, it can deliver all the traditional passive advantages (greater brightness, richer colours, no flicker, no crosstalk and a less tiring experience) without displaying the traditional disadvantages of visible line structure, jagged edges and a reduced resolution.
There's no overstating how much this improves the 3D experience. In fact, it's so good it suddenly got us interested in 3D again - and believe us when we say that this is no small achievement.
