Sony’s EX720 Series of 3D HDTVs Not a Good Choice for 3D Use

March 5th, 2012 · 18 Comments · Other S3D Tech

If you were planning to go for one of the more affordable 3D HDTV series from Sony, namely the Ex720 series that offers 3D-capable TV sets with size of 32, 37, 40, 46, 55 and 60 inches and you want to actively use this television set for 3D, then you better not. I’ve read some people complaining that the 3D effect is really bad on this lower-end series from Sony due to the presence of a lot of crosstalk, but I was not expecting that it is so bad. Recently I’ve played a bit with the 46-inch version of the EX720 (Sony KDL-46EX720) and I was surprised to find that the situation with the level of crosstalk is so bad, it is way more than you would expect to see on a 3D HDTV. It is probably even worse than on the first generation of 3D Vision-ready monitors that came out a few years ago, and you’d probably not expect that from a more recent 3D HDTV (the models from EX720 series were introduced last year), the level of crosstalk you get in 3D mode on the EX720 totally ruins the 3D experience. So my advice would be to stay away from the Sony EX720 series if you are planning on using these in 3D mode, and there is not much reason to buy this model if you are not going to take advantage of its 3D capabilities. If you are looking for another 3D-capable solution in that price range, there are quite a lot of other options that will provide better 3D experience – passive 3D solutions from LG or active from Samsung for example. And if you are already an owner of an EX720 3D HDTV from Sony, you are welcome to share your feedback from how your 3D HDTV works in stereo 3D mode and if you are happy with the result. I’ve spent a few hours trying to tweak the settings of the 46-inch EX720 TV set and as a result got a very slight improvement, but the end results were still very far from satisfactory. There seems to be no new firmware updates addressing the bad 3D performance for the series available yet, and I’m not sure if it would be possible to get better results via a software update only, maybe the LCD panels being used are just not good choice for 3D and that is the cause of the problem. So my advice would be to just stay away from Sony’s EX720 series of 3D HDTVs and instead go for another brand that will provide better 3D experience within the same price range.
