Rated 3 out of 5 by 1Andrew1 Not quite what I expected
- the box is huge (feet/stand comes already mounted), so the box is very wide. So, make sure you have a lot of clearance before trying to take that inside the house
- finish is overall very good (not including the remotes, which are very cheap looking, specially the "touch" one #it actually does not have any touching capability per set - you push the top against the bottom plastic base#
- feet can be mounted in two positions #on the edges and closer to the middle, which could have been at least 6" apart - the tv does not look very stable with them on their current centered position#
*I am not sure why Sony decided the 79" be the only one across all 2014 x900 and x950 models with a different panel/passive 3d.
Apparently the panel is the same used on the 79" LG #IPS with FPR# which inherently, due to the tech, has higher black levels and higher lag.
- In a bright room, the TV is great. In a movie theater/dark#er# room, not so much. I am not sure that is related to the IPS panel or not, but heard from 65" users that theirs provides better blacks. As there have been no professional reviews of the 79" yet, this is subjective at the moment.
- You will find the usual led/edge-led issues #uniformity, banding, clouding and blooming#. Some you should be able to control via setting better than the others. Keep in mind, some of the above are also really dependant on the source material/compression
- Motion, for the most part is Ok. No major issues, but nothing spectacular either.
- You should be able to play games without any perceived lag #as long as in "game" mode#. I have tried ps3, ps4 and xbox one games and they all played well
- 3D. Always heard passive 3D is much better than active. This being my first passive 3D experience, I will have to disagree.
You will see a lot of bluryness when watching any 3D blu-ray and worse, horizontal lines #passive 3d tech halves the vertical resolution# whenever there is a white/light color background on the screen.
I don't know if that can be attenuated via firmware or it is inherent to the panel/FPR tech used only on this model #all others use active technology#
- Remotes as I mentioned above are cheap looking and neither is very functional #due in part to the software/user interface#
i.e. Samsung and LG remotes are much better in design and functionality
- User interface is somewhat "busy". It requires a lot of back and forth and forces unecessary navigation.
i.e. in order to move from a movie to the usb, you have to click on "home", navigate to "media server", scroll and click on the usb drive.
In some sub-menus, when click "return"/back it will take you back to home screen instead of the menu you were.
- At the moment, you can only play 4k files from the usb or other directly connected devices #not including netflix/youtube - on the youtube, there is no way to display the actual resolution the file is being played on#.
Playing files from your PC via DLNA gives a "content" error and only sound is played *#Samsung 4k sets played almost all 4k files out of the box#. Hopefully this will be addressed soon via firmware update.
- Being a passive 3D set, it comes to mind, that if and when 4k 3D is available, the set will neved be able to play it at full 4k resolution due to the technology used.
- Currently HDMI 1-3 allows for only 4:2:0 instead of 4:2:2 and 4:4:4. It is not known if those can be upgraded via firmware as it depends on the chip used in the TV. You can find out the difference here http://en.wikipedia.org/wiki/Chroma_subsampling
- Speakers sound great for a TV. The question is, does the extra size #both in width and depth# presents a good trade off?
It depends, you are not or does not already have a surround set or is thinking about moving the TV later to a bedroom, than yes, otherwise no.
The sound is good, but is not a surround setup, you will loose the perception of being engolfed with sound from all directions.
- The wireless sub adds more bottom and helps fill the room #small to mid size#
- For those with a surround sound, Sony should have provided a way to use the speakers as front ones when using a receiver 5.1/7.1 setup. That way you would be able to take advantage of the built-ins and not have only the extra width they added to TV for nothing.
It is not a TV for all. It strikes a balance between size and image quality that I am not sure most will find optimal.
Some decisions made when building this TV seemed not well thought out #passive, panel choice, extra thickness of the TV due only to the speakers, remote controls, centered feet position, etc#
Is it a great TV, yes. Are there better on this price/size range?
Some will have better features and/or picture quality on certain sources/content, and others are still an unknown #only specs are available - i.e. Panasonic AX900, Visio Reference#

Rated 1 out of 5 by MovieNut Mounting Legs too far apart for Most furniture
NEW X900B 4K TV Urgent, you need to change the stand , it is way to wide 80" will not fitany standard console?? The largest I have found is 77". You have madea big mistake on this size for the stand, you should have made them closer instead of so wide.Thats why I am not buying this product.You need to put

Rated 1 out of 5 by JimSatala worst mistake of my life
This TV Hasn't Functioned properly since it was delivered on July 1st 2014,
I have spent 30 hours on the phone with Sony Support and they don't know what to do... I purchased it directly from Sony that was a big mistake they are not set up to do service I was told to pay out of my pocket to ship it back and that would cost around $600.The TV keeps shutting itself off and rebooting and when it does the TV says it cant detect input signals and no matter what you do it wont work unless you shut off the TV and give it time to cool off then it will function for an hour or so..also WiFi on TV is really substandard it must have a defect in its RAM or Flash because if you are watching streaming video the tv lock up after 30 mins and reboots.

Rated 3 out of 5 by boed Side speakers killed the sale
I have a 65" 4k Sony currently. The TV is pretty good but I want something bigger so I was going to move the 65 to another room and get the 78" 4K Sony. While the motion still doesn't compete with plasma it is adequate on this model. The only problem is the massive side speakers take up a lot of space and make this unit stick out significantly from the wall. It also makes the unit heavier, limiting the number of TV mounts you can use. Seriously, who buys a 4K 78" TV and doesn't have a receiver or preamp and better speakers?
