Sony's KDL-EX720 series represents the least-expensive model in the company's 2011 TV lineup with 3D and a 240Hz refresh rate--both bullet points that the less-expensive KDL-EX620 series lacks. It's also Sony's highest-end 2011 TV to use a matte-screen finish--not a bullet point, but something we really appreciate. The latter helps improve image quality in bright rooms, but overall the EX720's strongest suits have little to do with the picture. Those include miserly power use, extensive Internet content options, and a competitive price compared with other active 3D-compatible LED-based LCD TVs.
The main missing link is Vudu, and while many others (namely Amazon VOD and Qriocity) can duplicate Vudu's VOD offerings, none currently offers Vudu's 3D on-demand or the superior image quality of Vudu HDX. We'd also like to see support for a major subscription music service, like Rhapsody or Napster, but doubt it's coming since Sony is pushing Qriocity.
The EX720 has a Web browser, although it's even slower and more annoying to use than the one on the PS3. With a few minutes of frustrated waiting for it to load hulu.com, it crashed the TV, and we never got it to load a video. It should be avoided unless no other Internet access method is available in your living room.
The company didn't add the ability to adjust dejudder processing beyond the four presets. Other advanced options are fairly standard, and don't include any of the wacky processing extras found on higher-end Sonys.
Among edge-lit LED-based LCDs, the EX720 performed about average, from a 2D picture quality standpoint. Overall it matched the score of the significantly less-expensive, non-LED >Samsung LN46C630, for example. Strengths include solid color accuracy in bright areas, very good reflection control in bright rooms, and fine video processing. Its black levels were a bit lighter than the competition, however, and uniformity fell toward the bottom of the pack.
