4k Television

I'm considering buying a Samsung UHD 4k TV receiver, and have Cox as my provider.  Does Cox offer 4k service?  If not, or if only for certain programming, when will it be fully available to us subscribers?  I'd like to know before purchasing one of the UHD 4k receivers.

Cox doesn't provide any 4K content. I don't think any broadcaster is putting out any 4K content. Only find 4K online or physical medium, like a harddrive or soon coming to Blu-ray. I don't think there are any plans to provide 4K either. Cox is making room in the analog spectrum mostly for broadband bandwidth. Would be hard to burn the candle from both sides, so to speak.

Health Edge, I'm most appreciative of your info and weighing in on this topic,but I gotta; admit I don't understand a thing you wrote!  Back to the original question, does Cox expect to offer 4k UHD any time soon?

What channels even have 4K video? Cox can't offer any 4K until some 4K channels actually exist. And talk about bandwidth hogs...

Service providers, such as Cox, Verizon, Time Warner and DISH, won't provide 4K content.  They don't even provide full high-definition content (1080p).  Our service providers don't have the capacity to handle all that bandwidth to all their subscribers.

As far as 4K sources, you'd have to look to the Internet.  Internet sources connect to your UHD TV via Smart Apps on your TV, a Roku player or an Internet-connected media server in your home.  That's the "online" Health mentioned.

Even if your UHD TV is connected to the Internet, you'd have to find a 4K source.  Netflix and Sony offer a few films you can download to a media server and play on your UHD TV.

As opposed to down loading an entire film before you can watch it, there are new streaming services becoming available...at a price of course.  A streaming service is like YouTube.  Meaning, you don't download an entire video from YouTube to your computer but, instead, watch it as it's transmitted from the server at YouTube.  You watch it while it "streams" from the Internet.

As far as these 4K Internet sources:  UltraFlix, Netflix 4K and 4K streaming from Amazon Instant Video.

4K Limitations:

UHD adds more pixels but, currently, it's coloring process is limited to 2K technology.  UHD has the potential for a wider color gamut, but there is NO technology to implement it.  Meaning, you'll see more detail but the color will be off.

Even if the color technology for 4K soon becomes standardized and implemented, your Samsung TV will not properly handle it.  Your Samsung must have "Full Capability" HDMI 2.0 connectors.  Full Capability passes data at 18 gigabits per second.  Your new Samsung will only pass data at 10.2 Gb/sec.

People purchase 4K just to brag about it, but in reality, they couldn't tell the difference between 4K and 2K.  Save your cash and wait until you can tell the difference.  And I don't mean tell the difference at Best Buy because Best Buy uses special equipment to produce 4K images for the UHD TV sets on their shelves.  Do you have special equipment in your home?

I have a Sony xbr65x850b 4k tv and believe me the difference in my home is amazing. Everything it receives is upscaled to a far better picture than any 1080p tv I've seen. What limited 4K content there is available is spectacular. Colors more vivid and exceptional black levels create an image unseen with 1080p sets. I am continually amazed at the details ( actors individual eyelashes, the direction of a blade of grass is bent on a golf green) I would never have noticed on my old 1080 HD set Only thing I would caution is one must have the higher internet speeds required to be able to stream 4K content and from what I've read a minimum of 55" screen size to see the difference.

Does that TV have  HDMI version 2.0 compatible circuitry?

kenneymcc, bear with me on this question...are you saying that 4k content streamed via the internet is what's giving you such great, clear pictures?  Do you see any similar improvement in clarity for the signals received through your Cox TV cable?  And when you stream from the internet, what are the sources you are tapping into...Netflix, Amazon, etc.?

Thanks for joining in on this one...all info is valuable, and I started with practically no info!

According to Sony website the xbr850b tvs do support HDMI 2.0 https://us.en.kb.sony.com/app/answers/detail/a_id/45145/p/61659%2C62766%2C93313%2C93962/c/65%2C66/kw/hdmi%202.0 edit I am using Monster 18 gbps HDMI cables and cat6 Ethernet cables

hpu1966 Yes I see a noticeable improvement with all HD program channels on my Cox service. For streaming I use Netflix, Youtube, Amazon and Sony entertainment network. Hulu and Vudu are also available as well as lots of others which I do not subscribe too. The Netflix TV app has 4K content(but very little)but no 3D content. My Bluray Netflix app as 3D content but not 4k. Kinda strange since the TV is also 3D ready and able to stream through some of the other apps but just not from Netflix. One of the best 4K content out there is Netflix House of Cards which is produced in 4k and shown in the Netflix 4K menu. Again I must say that unless you have the 50 mbps internet speed you will not access that 4K menu from Netflix simply because it requires a speed of 20-25 mbps and none of the TV's have the processer speeds of a PC to process it. My PC reports 55.3 mbps but the max the TV has ever shown in 22Mbps but that works. I'd suggest you check with the TV your thinking about to see if it does indeed have the ability to UPSCALE

Yes, your Sony is equipped with HDMI 2.0 ports, but are the ports "full implementation" or "full capability" HDMI 2.0?  "Full" HDMI 2.0 ports will properly handle the advanced color of 4K, which is 18 gigabits per second.  Your Monster cable may be rated at 18 Gb/sec but are the HDMI ports on your TV, cable box and A/V receiver rated at 18 Gb/sec?  Sony will list HDMI 2.0 on the spec sheet but leave out the bandwidth because they won't reveal what their products can't do.

Your 4K may look "amazing" but the technology hasn't reached its full potential.  For example, there is no standardization on an expanded color gamut, compression scheme, high dynamic range or high frame rate.  If you buy a 4K TV now and such standardizations are finally reached later, your 4K won't properly handle the picture.  Your 4K will still provide a picture, but the color will be wrong.

In addition, the 4K sets on the shelves and in the warehouses today won't be future proof.  Meaning, again, if the standardizations are finally reached, you won't be able to just update the software or firmware on your current set.  It'll be hardware changes.

4K TV sets are at stage of cell phones in the 90's.  Yes, they're a great idea but there's room for drastic improvements.  Until the Consortium standardizes the technologies, it will be the Wild, Wild West of formats for any 4K content.

Bruce I'm old enough to remember when color TV was first broadcast. I remember paying a very high price for my first VCR then replacing it with a 4head hifi stereo VCR. I remember for years the debate over VHS vs Beta, I remember purchasing my first 36" rear projection TV and thought it could not be any better. My first pc was a 4mhz processer then lots of newer ones along the way untill they got to where newer and faster processers do not provide any advantage for me because of what I use a pc for. I had one of the first ever post mounted mobile phones in my truck and that was not that long ago (1985 if I remember correctly) so I really do hear what your saying. I look at things a little differently I enjoy life as it comes because I know if I wait till the best comes along that it will be out of date by the time I get it home. I keep up with a few forum sites and read others who are like me and fully enjoy our TVs and what it can do. I also read from those who are so into all the techinical stuff and continue to tweek their setting to the point where no long enjoy watching a program because they are so fixated on removing the slightest hint of shadow or corner light leak. They watch a HD movie in cinema mode with the black bars top and bottom the fixate on those bars instead of enjoying the movie. Perhaps your prediction for standardizations may come true then again the technology my set has now may become the standard, then again It may be able to just receive a firmware update to meet the new standards. There is already talk about 8K but experience tells me that is probable years away if ever. Enjoy your life while you can and do as you feel is best but please don't miss out while waiting for something better because there will always be something better just around the corner

Ver 2.0 HDMI chips just recently became available. Sony hopes a software update will work. HDMI.org isn't convinced it will work.

All your examples are consumer-electronic equipment designed with ADOPTED standards.  It's not a question of the best equipment or the latest gizmos and buzzwords.  It's a question of the industry adopting a standard so Hollywood, audio/video equipment makers, film distributors and Internet entrainment sites can produce fully-compatible media no matter what the consumer plays it on.

Currently, there is no technology available to implement the full color potential of 4K Ultra High Definition TV.  The possible standards are as follows:
  - REC709 (B.T.709) is the existing HD standard for the color gamut of 1080p, which is what your Sony is using.  It's 2K technology.
  - x.v.Color (xvYCC) is not a defined color gamut.  It's only expands the color of the existing HD color gamut standard, REC709.  Since it's not a standard, not all movies will be encoded with it and not all video equipment will recognize it.
  - REC2020 is widely suggested but may not work.
  - P3 is currently used for theatrical digital projection (DCI [Digital Cinema Initiative]).

Using your color TV example, it's like buying an early color TV based on either the dot-sequential color system, line-sequential system or Telechrome...only to discover later the FCC adopted the NTSC Compatible Color System.
