3-D Conversion: It is the most accurate 3d conversion I have ever seen on any TV. I have seen many 2d to 3d conversions and never really used them because they really didn't work so well unless you had a bright scene with rough edges such as mountains. I am a video gamer myself, and I was very pleased to know that the 3d conversion does work in gaming mode and even in dark games such as The Last of Us it was very impressive at simulating 3-D.
Contrast Ratio is Similar to OLED: I have an OLED display, and with the contrast enhancements and black level correction feature combined with Live White and Warm 2 and auto dimming, the display pretty much looks identical to an OLED display except for pure black screens you may notice a little wash out. Under normal usage, it's pretty much identical to an OLED display; I would say the OLED is about 10% better but being the fact that this TV is significantly larger and contains upscaling this wins over.
Upscaling: The up-scaling done on the TV exceeds any I have seen before. If you turn off the up-scaling features it will look pretty much the same as any other TV when running 1080p on a 4k screen. The biggest problem I have seen with 4k displays, such as my computer monitor is that there is an excessive amount of blur and color quality loss when up-scaling. When you turn the features of this TV on, it makes it look identical to a native resolution display, but even better. And unlinke most TVS, the upscaling features work even at 4k resolution, so when playing video games you can still increase the details of low resolution textures.
Lifespan: The lifespan of this TV is about 50,000 hours. This is assuming you never replace the backlight, if you did replace it instead of buying a new TV it would reach 80,000 hours. If you watch TV 8 hours a day, expect this TV to fail after 16 years of usage, if you're the normal and watch TV 4 hours a day then this TV will last 32 years. LCDS have longer lifespans than OLED displays, in some cases as much as double depending on the display itself.
Input Lag: This TV has one of the lowest input lag response rates I have seen for a midrange 4k TV. In gaming mode, the input lag is roughly 40 miliseconds. You're simply not going to find a better TV with a lower input latency at this range, unless you swap to OLED. But most of those TV's turn off the enhanced features such as upscaling. Sony allows you to maintain upscaling even in gaming mode, and 40ms isn't that bad.
X Reality Pro+Detail Enhancer: One of the features of the TV is to compare lower resolution textures and replace them with more detailed textures. I will admit it's not as good as the demos show on youtube, but it is very impressive. X reality PRO works exceptionally well in video games, because it removes the blurred effect of up-scaling. However for movies, you'd be hard pressed to tell the difference unless you have also enabled detail enhancer. Check the photos in the review for a before and after enabling these features, it makes a 1080p movie look much higher resolution.
Color Quality "Live Color": Color quality is always going to be a personal preference, Live Color ultimately gives the same effect as increasing the color saturation, but it handles it much more intelligently and causes far less bleeding. Live color works more by changing the color tones to be more
Fast Start Calibration: A cool feature of this TV is it intelligently learns which settings you visit often and optimizes the startup of the TV when you turn it on by turning those features on first. I can boot the TV up in about 10 seconds with this feature enabled; it’s turned off by default as it does consume more power on standby. Some review mention they hated how slow it took to boot and it should provide an option… well it does so I am not sure what they are complaining about.
Interactive Built in Guide: This TV comes with a handy manual built right into the TV with a table of contents, it explains to you how to customize your TV and what each option does, and it’s not horrible translated from another language either… it’s easy to understand.
Center Stand: A problem with larger 4k tvs is they seem to like to use edge stands, but a 65 inch tv isn’t going to fit on my TV console. Thankfully this TV came with a center stand option, and it fits on my console without issue.
There's always a negative to things, I don't believe in truly perfect products. There's always room for improvement, and I can't blame the TV for some of the negatives I have found. Let's start with the biggest negatives.
* Viewing distance is a huge factor in the quality of this TV if you want to display 4k content. If you're not within 5 feet of the TV, you are not getting the full benefit. However, you are still getting benefit at the 8-9 feet ranges, but only at 1440p and not 2160p. This is why a lot of people say 4k tvs look good even at further distances, which is technically true but they're not getting the full 4k benefit, it's just better than 1080p. 4k is meant to be viewed on larger screens, so the larger the screen is the more distance you can move away from it. Unfortunately with the 55 inch and lower models, you'd have to be as close as 4 feet and once you leave the 8 feet range it's virtually identical to a 1080p display but triple the cost. However, keep in mind that since it upscales to 4k you can sit twice as close to your TV and see 1080p content in roughly the same quality but better, so you're effectively increasing your TV size at 1080p because you are sitting twice as close to it.
* Calibration from the TV's default settings are off, most people will be satisfied with the default settings. But just to show you how much better you can make the TV by changing the settings I have added 2 photos of Tomb Raider Definitive Edition from my TV. The first image is from Standard - General mode, which is what I consider "default" settings. The cinema mode is more accurate, but it is still off in colors and brightness slightly. When you're comparing the 2 images of Tomb Raider, the colors of the second image is far more accurate. There isn't a blue overtone and despite being darker (about 50% less backlight) you can see much more detail in the dark areas of the game as you couldn't before. You will have to play around with your settings to make sure you’re getting the best. A big problem is a lot of people like to turn the upscaling to max and increase sharpness, this causes a halo effect and distorts colors. You can change the settings manually, but it's highly recomennded you use a claibration disk (for free online or a website) to make sure you're calibrating the display properly.
* 3d Viewing Distance remember what I said with you should be about 4 feet within the display to see the full benefit? Well, 3d requires nearly double that distance. A proper 3d distance for a 65 inch TV should be about 8 feet for 1080p content, if you get any closer you will experience cross talk in certain areas of the screen. This is particularly noticeable when you are using 2-3d conversion, the top left hand side of the screen is pretty much not converted at all and it makes it difficult to play video games without being at least 8 feet away if you intend to use the 3d conversion. You have to make a choice on this one, if you're wanting 4k and 3d to be perfect you're going to have to buy 4k TV's in the 100 diagonal size range so don't buy this TV for the 3d alone. Regular 3d doesn't suffer this problem as much though, because it is using Side by side or over and under, the quality is best at further viewing distances but it’s not that bad. So if you're not using the internal conversion feature from 2d to 3d, you won't have to worry about this problem.
* 4k at 60hh on PC: This is a 4:2:0 display, if you're using an AMD card you will ony get 4:2:0 color which is terrible for a PC because a lot of things will not render properly, sort of like swapping your color mode to 16 bit. If you have an nvidia card, it is upsampled to 4:2:2 and you will not notice a difference except maybe a few graphical glitches in windows. The big issue though is, 4:2:2 is incompatible with SLI at 60hz; this means if your game does not support 59hz natively you will not be able to use 2 video cards at once to render 4k resolution. This may be a deal breaker for many as it's a lot worse running 4k games on one card. This is not the TV's fault though, it is the video drivers so I can't really remove a star over this. You can do a registry hack to make all games 59hz, but it may cause screen tearing. Keep in mind 4:2:2 at 4k works perfectly fine with one video card. But once you see the 1080p upscaling, you'll probably not play at 4k resolution anymore because it's quite detailed. NVIDIA and AMD both have the same issue, NVIDIA has officially confirmed that they are working on this issue but not ETA as of this moment.
*Menu options are horribly placed: This TV isn’t very user friendly, like most Sony TV’s for whatever reason they put the picture settings on two separate menus. You have the basic settings on the option button, and then the more detailed settings on the HOME button. I just wish they put it on the same spot, there’s no reason to put two menus in the TV to do the same task… all it does it cause confusion!
Conclusion: It’s up to you on how you want to use this TV, you can buy it alone just for the 1080p up-scaling which is quite visible at further viewing distances but you're going to need to move in closer to the TV to take full benefit. Effectively you can make a 55 inch TV, be equivalent to a 70 inch screen (in peripheral vision) just by sitting at recommended distance as 1080p loses no quality when upscaled. Because of this, I personally do not use the 3-d mode on my tv as it requires me to be 9 feet away (for conversion only, true 3-d is fine).
When I bought this TV, I was expecting to play video games at 4k resolution with SLI. Sadly I found out I can't, so it's an expensive investment that in the end didn't do what I wanted. But the other features of the TV, such as the upscaling and contrast surpassed me running 4k natively that I actually enjoy the upscaled 1080p, especially being much closer to the TV games feel more immersive.
While many reviewers will tell you that most viewers will be hard-pressed to tell the difference between 1080p and 4k TV's in terms of 2D content,, the one huge leap forward 4K actually did make was the huge benefit it brought to passive 3D.
In the past (still ongoing as well) there was some debate about passive versus active 3D, with the biggest problem for passive 3D being that it dropped the the resolution from 1920 x 1080 to 1920 x 540 (which meant at close distance with certain content you could tell that the content was no longer HD.). With a 4k TV you now get 3840 x 1080p resolution while watching passive 3D content. In other words you still get full HD while watching in 3D (the upscaling from HD to 4K UHD is very good). In my mind this clearly and unambiguously makes passive 3D superior to active 3D which has more problems with artifacts (crosstalk) and requires heavier far more expensive battery- powered glasses.
So on this basis I went ahead with the 2014 model. I have not been disappointed. Regular 2D viewing is stellar and the 3D content is a big step up from what I had with my previous active 1080p Bravia 3D TV.
In particular I was very impressed by the 3D emulation mode which takes 2D content and adds some 3D depth to it. While it is not as dramatic as true 3D content, I have found that it adds just enough depth to make a 2D image more realistic. In short the 3D emulation mode is actually something I find myself using regularly. (the remastered Star Trek TOS are amazing when viewed this way!)
So with full HD 3D and much much cheaper 3D glasses I believe passive 3D is the way to go with the new 4k TV's.
Strangely, many manufacturers shifted away from passive 3D even as the 4K technology that gives it a huge boost is becoming the standard.
Regardless, if 3D matters to you at all I would heartily recommend the Sony 850B in specific; and in general recommend passive 3D and 4K as a synergistic combination that makes sense.
If 3D is not a big factor for you then the 2015 850C model is probably the way to go.
