Rated 4 out of 5 by Defjamz Great 4K set
After reviewing available 4K sets, we decided to go with the 70X850B from Sony. Competing sets from Samsung were nice as well, but they offered no 70" options, and 75" was too expensive. The Sony is not perfect, but it does offer fantastic colors, good motion handling, and decent black levels (i'm used to plasmas). 4K resolution is awesome (what little content that is available anyways), and gaming is a joy on this set. My major gripes are a lack of full color management controls, and no 10 point white balance. I have performed a full calibration with my meter and calman 5, but I can only go so far without those controls. But, I am able to get a nice, saturated image with good 'pop'. Gamma curve is difficult to get flat, but 'cinema 1' does get fairly close. Panel uniformity can also be an issue for some, but I lucked out with mine having minimal clouding. It is certainly no plasma, but the image is generally very pleasing to watch, particularly with ambient light. Overall, highly recommended!

Rated 4 out of 5 by Yamaki Best Picture Ever?
First, let me say I am impressed with the clarity, color depth, black levels and overall presentation of the Sony XBR70X850B monitor. And it would have gotten a 5 Star rating except for the extremely frustrating difficulty in getting this TV to make the HDMI "handshake" with several audio visual receivers, and HT processors that have the required specifications to support higher level resolution signals. The problem persists so a word of warning to prospective buyers...be prepared to dump your HDMI switching scheme via AVR or processor in favor of individual HDMI connections to the monitor from each source with a corresponding parallel audio connection from each source to your AVR or processor. The last part only applies to those who eschew having the monitor process the audio.
Now, out with the bad and in with the good. I was not trying to "future proof" my viewing pleasure by selecting a 4K capable TV. Rather, I was looking for the best picture and, to my eye, the Sony XBR line of 4K TV's wins the best picture ever award when compared to standard resolution LED and plasma monitors.
With very little tweaking on the settings you can settle in and enjoy a fantastic result, even when viewing non-4K content. Regardless of whether you are viewing a 1080p BluRay, your standard 720p cable fare or other similar content, you will definitely see a difference in quality.
The "SMART" functions are very easy to access and use. If you have a streaming BluRay player in the home, you'll notice there are other streaming options open to you now and the access menu is extremely informative and well designed.
Even though you may not be interested in 4K content, if you are looking for the Best Picture Ever, you really should preview this TV and compare it side by side with the standard LED offerings out there. You'll be glad you did.

Rated 5 out of 5 by JTMD Excellent 4K HD TV
Extremely happy with Sony's new 70 inch 4K HD TV. Worth the extra price over their 65 inch model. Great colors, excellent blacks, outstanding upscaling. I prefer this model's active 3D versus passive 3D, VA screen versus IPS screen.
This 70 inch HD TV has approximately 35% more screen area than my previous 60 Inch Sony HD TV. I can sit a lot closer for a more immersive effect without seeing any pixelation.

Rated 5 out of 5 by kingkenwood Absolutely Stunning Picture!!
My 71" Samsung DLP crashed on me a year ago. I had been waiting for a suitable TV for my movie room to come along. Long story short,Samsung doesn't have any kind of customer loyalty program in place. I had my eye on their 75" UHD TV.As it turns out,I ended up choosing my Sony 70" 4K TV!! This baby doesn't disappoint either. Bought a PS4 and Xbox 1 along with Sony's BDP-S6200 3D Blu-ray player also. I can't say that I've ever seen a picture this crisp and sharp!! Gonna go back and look at some of my old movies now!!! Great Job Sony!!
