Sony KDL-55HX729 3D LCD HDTV First Impressions Review$999.00
The KDL-55HX729's 3D glasses looked about the same as the Sony 3D glasses we reviewed in 2010. They're active shutter, front-heavy, and bulky. They're not the most uncomfortable glasses we've tried on, but other manufacturers' clearly put more thought into overhauling their 3D glasses.
The TV's 3D effect seemed to be a bit better than what they offered in 2010. The effect dropped out at times, such as during fast motion, when something was in the immediate foreground, or in high contrast areas, but it was a marked improvement over last year's effort. The effect was also a bit deeper than some of the passive or glasses-free 3D we saw, but had that annoying active shutter flicker.
As mentioned above, fast motion caused the 3D effect to break down, but it wasn't as bad as we've seen previously. Some of this might be due to the TV's 480Hz refresh rate, which allows 240Hz to each eye. No 3D we saw on the show floor was perfect, however, regardless of the technology used.
