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.

    Worse then first gen?! Wow, I bought one when they first came out maybe november, 2 years ago. It was so bad I pawned it to a friend for less then 2/3 and threw in two pairs of 3d glasses($100 bucks a piece back then) and felt bad for him afterwards.

    I have a Sony NX710 and I was absolutely appalled at the crosstalk when I first got it. However after a lot of hassle, I ordered some extra polarising filters for the glasses from the Sony US website. They were actually giving away for free to US residents but wouldn’t even sell internationally so I had to using a forwarding service to get them sent to Australia. The filters meant I could tilt my head without the 3D effect disappearing, but they didn’t really improve the crosstalk.
    However, over time I’ve noticed that if I let the TV set warm up first, the crosstalk is significantly reduced. So if I plan on playing a game, I just turn the TV on and let it warm up for 20-30mins and I get a MUCH better experience. Still not perfect though.

    I bought the ex720 40 last month.. I am another disappointed user of this series.. Sony should not sell this after, victimizing many consumers like me.. I am frustrated..

    I buy EX720 2 months ago and i was very disappointed by this “3d TV” . This is our first 3d television, and i am not sure that i will buy another in future.. Since i buy it i have tried all, i’ve read all possible forums, write many times to Sony about the problem, but they told me that there’s no problem with the TV and i am the first who write about bad 3d experience on this model (WTF?!) I saw in Sony’s official support forum and there’s lot of people with same opinion – THIS TV IS A CRAP! I dont think, they will ever fix it with update, as i understand the problem is from hardware not software.. it’s a big shame for Sony, they lost me as a customer!

    I found the stereoscopic effect is really poor on the top screen edge. it brings the farther background eg. mountain and such too near and this can be verified by closing one eyes and you will see poor image splitting on the top and weaker around the bottom edge caused by overlapping left/right images. I am not sure if this was caused by the refresh rate or something. Sony support talked me through menu and when I tried to advise them, they put me through the menu and ignore my points completely. I thought I was talking to Siri.

    I have this TV from one month and the 3D is very terrible, I’m very disappoined with sony they have stolen my money.
    it’s amazing that nobody has complained to sony fraudulent and misleading advertising!

  • 7 Angry Customer // Mar 29, 2012 at 10:54

    The level of crosstalk for my unit is like 50% of the other eyes.. totally unacceptable. I still do not know how I could miss out such details in the store. TOTALLY DISSAPOINTED!

    For those who own this TV, try setting ‘Depth Adjustment’ to ‘+1’ from the 3D Menu and ‘Depth’ to ‘13%’ from the Nvidia control panel (by default, it is at 15%). Does away with most of the crosstalk, while retaining a decent amount of depth.

  • 9 cost.jazzyk // May 12, 2012 at 16:38

    +1 at depth adjustments do not provide good viewing..also no nvidia control panel since i use a media station..(xtreamer prodigy, with no 3d settings of this kind)

    OK.. I bought this TV and cross talk is on top and on the edges, Sony support denied this issue and told me the issue is with my eyes !! It took me a month to figure out a trick to reduce the cross talk. Select game mode then increase the brightness to 75 or 80 or 85 and color to 95. The brightness will eleminate the second ghost image and since the picture colors will become cold, increasing the color value will make warm. It worked for me and I my tester was my non techy beloved wife who really noticed the difference.

    My first Panasonic 3D TV still outperformes any 3D LED TV. Shame on u Sony support

    any word on EX725 “series” ?

    I have 55 EX720 TV for a while and have the same problem on 3D, after I read thru the forum on AVS website Official Sony EX720 Owner thread. I try some setting that can reduce cross talk on 3D that I am happy with it.

    I use HD player to play 3D file to my 55 EX720. The file is 3D SBS and 3D ISO file. When I play 3D SBS file, I set the HD player to play 3D SBS file by select SBS menu in the option. This selection will feed 3D signal to 55 EX720, so on TV the 3D menu will turn ON automatically.

    On 55 EX720 3D menu, I set the

    3D Depth = 0,
    3D Glass brightness = Auto

    The Picture Menu on the 55 EX720 is set as follow;

    Picture mode = Standard
    Picture, Brightness, Color, you can set as you like
    Nosie Reduction = Auto
    MPEG Noise = Auto
    Dot Noise = Auto
    Motion Flow = Off
    Cinema Drive = Off

    In this setting, the 3D picture improve a lot, less cross talk on the upper half of the screen. I can watch the whole movie with more perception of 3D. The cross talk appear only in some scene and depend from movie on movie.

    For the 3D ISO file, it is much less cross talk compare to 3D SBS file. I watch AVATAR 3D ISO which it is display full screen on the 55 EX720. It is almost no cross talk at all. They may have some cross talk on the out of focus picture in the movie. But it is much less appearance.

    In this setting the picture show some flicker especially on very bright scene.

    You can try this and share your result.

    I own sony ex720 40 3d effect is very bad.crasstalk is irritating. but hd picture is amazing.. I like nvidia 3d vision for a good 3d effect…..

  • 16 Erik // Dec 28, 2012 at 12:50

    The crosstalk on my ex720 is quite a lot near the top and very much less visible near the bottom of the screen. So apparently, the TV can produce good 3D, but somewhere there is a technical issue so the crosstalk interferes badly further to the top.

    This can be easily seen when selection depth +-2 as opposed to 0 in the 3D menu. The crosstalk can be easily judged when holding the glasses infront of the of the high contrast menu text:. on my TV okay near the bottom and much worse near the top. There it is so bad that the the text cannot be read anymore.

    I can not see 3D side by side movie on 32EX720 Sony TV. Using USB input when i try to get in 3D Display the Side by side choice is not available; there is only “Simulated Mode” and “Off”. I need solution to view 3D Movie from this Sony television.

  • 18 harry // Mar 6, 2015 at 10:26

    Yes , 3D was rubbish and 3d glasses a waste of money. The worst part was that after 18 months the Sony Bravia double image ghosting problem appeared and made the TV unwatchable. Unfortunately it was 6 months after it ran out of warranty and it is cheaper to buy a new unit then replace the panel and fix the ex720. Only wish I saw your site BEFORE I purchased the Sony 40EX720 Lemon. Needless to say it the last time I will purchase anything made by Sony as the extra costs does not translate in better quality then TVs like Soniq, TCL or other cheapies out there.
