Saw the Sony 4k 65" first at Best Buy then at Frys Electronics. In Best Buy it looked good. In Frys it looked positively stunning (I think Frys must have a calibrated set). 4k brings a revolution in picture quality. The difference between, say a Kuro Elite Pro151FD, or a Sharp Elite 70" both of which I am very familiar with (and they are both awesome) and the Sony in 4k leads me to believe that this technology will be the major driver for the consumer electronics industry over the next 5 to 10 years much as the DVD was. I also believe that 4k software will become the standard within 2-3 years. The new Sony PS4 will be capable of playing 4k content.
Subjective Comparisons of picture quality are easy really, because there is no contest between HDTV and 4K.
The Kuro Elite and Sharp Elite are both superior to the Sony here, but the Sony is still very good
Both Kuro and Sharp Elite are superb, but seeing the Sony in 4K at Frys.... well, the Sony takes the cake on this one. Rich, intense, vibrant, accurate and really breathtaking
Image in motion
For me, the Kuro has been the champ so far and the Sharp Elite - as good as it is - still is not quite as good as the Kuro. But after seeing the Sony in 4K mode. WOW. The perception of three dimensional objects and their relation to each other moving in space moves things up a few notches on the reality scale. A scene in the 4k demo demonstrates this to great effect. A flock of McCaw Parrots fill the screen as they fly and the feather detail which is incredible doesn't blur at all during the motion. This is much closer to the way my eyes perceive real life. So, the Sony (in 4K) wins out here,
Once again referring to the 4K demo loop at Frys (not Best Buy), during the still-life 'red' scene I was drawn to the grapes sitting inthe bowl at the rear of the table .The image of grapes was more breathtakingly real than I've ever seen from a TV monitor, such was the resolution of form and color.
Makes me think just how good 8K must be!
