Decent 2d TV neither best or worse 120hz option for 3DHDTV,
UPDATE 3/30/2011: Amazon has removed the 240hz tag from the product title but not the “whats in the box” section. As this 120hz product is no longer being incorrectly advertised as 240hz, I am re-adjusting the rating.
WARNING: Possible Deal breaker concerning this TV.
NOTICE: As of 3/24/2011, I noticed via the Sony Style website that they state the EX720 is now only 120hz, not this advertised 240hz. I hope this is a typo on Sony’s end but if it is not, there is a serious case of false advertisement going on. I was specifically on the market to purchase a 240hz HDTV, as the price tag warrants it, and thus this may change the satisfaction level of this review. Before you purchase this product, make sure you know there may be a case of false information taking place regarding the refresh rate.
Update: It is confirmed that the this HDTV is NOT 240hz as advertised. It is only 120hz. The rating has been adjusted purely because it is false marketing and reveals little improvement over previous models which cost much less. One of the main reasons to get a 240hz HDTV for 3D is that you get 120hz per eye as the image flickers back and forth. If the refresh rate of the TV itself is only 120hz, this means you are only getting the 60hz experience when watching 3D. 60hz is what we are trying to get away from.
There is absolutely no excuse for false advertising, higher costs for features not present. If you are looking to get a 3D TV, make sure it is absolutely 240hz or else you are just wasting your money. If you want a TV but dont plan on using the 3D features, then this unit is ok but there are cheaper and better alternatives in that case.

Updated – Old Review:
The Sony Bravia 40EX720 is a decent 3D HDTV.
I was originally on the market for a HDTV in which to use as a computer monitor/gaming screen and after Sony revealed its 2011 lineup at CES 2011, I knew I had to get one.
The first thing I can tell you is that this TV is solid. I felt quite satisfied with the build quality (a bit of cheap plastic on the back, but I have yet to find a LED LCD HDTV that didnt have that feeling). Unlike the previous EX series HDTVs, the bevel on the bottom which looks grey in some pictures is actually a dark black. This was actually a downer for me as I kind of liked the grey strip on the bottom as seen in some EX7xx pictures. I love the menu system, it is a modified version of the 2010 menu system. The 2010 line of Bravia HDTVs made use of the Playstation 3 and PSP menu system to the point where they were practically identical. The EX720, and by my guess all the 2011 models, opted out of the PS3/PSP menu design in favor of a more streamlined version. It grows on you and generally I find it much more visually appealing and easy to navigate.
The remote is perhaps the best thing this tv has going for it. It has some handy buttons that work better than one would expect. The 3D button on the remote turns the tv into stereoscopic 3D mode, one more press and it turns it off. You can watch anything in 3D as the Bravia will emulate the 3D effect for non-3D content. Other remote buttons include a quick netflix toggle, internet video, Qriocity as well as a very handy HOME button.
The internet video works like a charm as well. I managed to watch youtube videos straight from the TV as well as browse online music libraries, though it was a tad sluggish (High Speed Cable).
Plugging in a USB drive with some short films on it worked as well. The TV will recognize the USB device and then you can go ahead and access what you wish to watch or listen to from it. There is no demo built into the tv for video, but there is one music track and a few pictures automatically installed on the TV.
No dead pixels. Lighting is even across the entire screen. Great black levels. Semi-Glossy screen (the mix between a glossy and matte). Color a bit faded, low bright levels. Certain colors seem washed out, and even at the most vivid settings, the color is a bit lack luster. This may have to do with the back lighting being minimal.
The EX720 may not be the best HDTV Sony has to offer for 2011, but for its features and capability… I would say its a competitor for sure.
Note: The North American EX720 was assembled in Mexico and the current LCD panels are the same Samsung uses. This may or may not be a problem for some TV buyers.
HDTV is NOT 240hz as advertised, but 120hz. In 3D, you will only get a 60hz experience (120hz divided by 2, 60hz per eye for stereoscopic).

|SONY responds to 120 HZ/240 HZ issue,
Here’s a transcript of my April 2, 2011 chat with a SONY representative.
user Ralph has entered room
analyst Sean_ has entered room
Sean_>
Hi Ralph. Welcome to Sony Online Support. I’m Sean. Please allow me a moment to review your concern.
Sean_>
Thank you for waiting, Ralph. I’ll be glad to assist you with the information about the feature of the TV.
Sean_>
Are you referring to the (120 HZ or 240 HZ)Screen Refresh Rate of the TV?
Ralph>
Yes
Sean_>
Thanks for the confirmation, Ralph.
Sean_>
The Screen Refresh Rate of the TV is 120 Hz.
Ralph>
Then Sony should correct its description of the TV. On Amazon now there is a significant discussion (negative) about this.
Sean_>
Ralph, the MotionFlow rate of the TV is 240 Hz.
Ralph>
This implies, does it not, that it’s a 240 HZ TV?
Sean_>
The Motion Flow is the technology to improve the smoothness of fast moving scenes to avoid bluring while watchinh movies or sports.
Sean_>
The Screen Refresh Rate is the actual refresh rate of the TV.
Sean_>
The MotionFlow should be enabled only when watching fast moving scenes in the TV.
Sean_>
The TV Refresh Rate will be 120 Hz only.
Sean_>
However, it will reproduce the images faster when Motion Flow is enabled at the rate of 240 Hz.
Sean_>
240 Hz is not the Refresh rate of the TV. It is the rate in which the MotionFlow technology works.
Ralph>
This TV seems inferior to Sony BRAVIA KDL40HX800 40-Inch 1080p 240 Hz 3D-Ready LED HDTV, Black
Yet SONY discontinued this TV. Why?
Sean_>
I’m sorry; Ralph. As we’re Sony Technical Chat support Team we do not have the information about the reasons behind the discontinuation of the KDL40HX800 TV.
Sean_>
We can only provide troubleshooting steps and information of the Sony products.
Ralph>
Thanks. But SONY made a mistake here and disappointed many consumers.
Sean_>
I’m sorry; Ralph that the TV was discontinued.
