4K TV Discussions

I'm thinking about getting a 4K TV to use with gaming on my PC. Last year I test drove one of the Seiki 39" 4K and I have to say the resolution was *almost* worth the 30Hz refresh.

Now that I'm seeing lots of panels come out with HDMI 2.0 I know that 30Hz is no longer an issue. (GPU horsepower aside)

Currently I'm looking at an LG 55UB8500 for 1566.66$ from NCIX (I get a deal through work)

Are there any other innovations for 4K coming down the pipes that I may not have heard about that might make me wait a while longer?

This panel seems to hit all the checks for me - 4K, IPS, 120Hz @ 1080p....

I would be ready to guess that come Christas time, all 2014 models will have a huge discount to make way for the next generation of 4K TV's. Even compared to last year, the prices have been falling steadily.

As to what will the next models bring versus 2014, I can only imagine faster GPU/CPU for the smart portion of the TV. Maybe better refresh rates but nothing else. To me, the 4K TV's can't become higher tech than 1080p for the simple reason 1080p has paved the way for them. The first smart TV's were in the HDTV family so it is logical to me that 4K can only improve picture. Just my 5 cents.

Be careful with the LG. It doesn't have playback support for near the same number of media formats as the 2014 Samsung 4K televisions.

The LG also only has MHL 2.0 whereas the new Samsungs have MHL 3.0 for connection to 4K capable smartphones.

The use case for this TV for me would be for PC gaming - so yes there is an abundance of content in that vein.

As for regular "TV" content - no there are only a couple shows on NetFlix currently - House of Cards and Breaking Bad. More on the way, but I'm not interested. Its all about PC gaming for me.

That's the bummer right there, Netflix. Apparently not all TV's have the capability to stream 4K from them. It is the case with Panasonic TV's right now....and I'm sure there are others that will have the same problem.

I was looking to buy a Panny but after reading that the decoding chip they use wasn't compatible with Netflix, I backed away. Might have to splurg and get the Samsung instead. And not the curved one.

Aah! Finally some Canadian 4k TV discussion. I bought my 2013 Sony XBR-55x850A mainly for viewing my photos in 2180 res. Now I'm getting a hankering for some 4k video. Unfortunately in Canada Sony's Unlimited UHD Service isn't available yet. The US has the service and they offer many movies in 4K. Another unfortunate thing about my 2013 model is that it doesn't have the ability to read a 4k video file or stream any 4k Netflix unless one buys additional hardware for $400. I'm not too ticked off as I do enjoy my photos in 4k and I suspect as time goes on more options of 4k video will become available in Canada.

One more thing, my set does have a HDMI 2.0 input, so video games should plug right in and play 4k on the screen.

You don't need HDMI to play games - just to play games at 60Hz rather than 30.

Since I'm using a PC for input I have the ability to spoof IP addresses so I can pick up US content if I wanted. I think the biggest thing holding me back (or two biggest I should say):
1) scaling in windows 8.1 to make text easily legible
2) I also would like something that incorporated GSync technology

one thing that would drive me away from an LG is that LG has been encrypting their firmware / bootloader, etc. for a couple years now. Even though they use an open source Operating system, they aren't very open about sharing the tools used to create. Apparently they don't like people hacking around adding useful features or fixing bugs. Openlgtv / lgmod development has slowed down as a result.

From what I understand Samsung on the other hand has been fairly active in terms of a community devoted to adding features (SAMYGO).

I'm not a gamer but my understanding is that one needs a UHD output signal (2160 resolution at a specific HZ) from the PC and to handle all the data required to do UHD, one needs a HDMI 1.4/2.0 or Display port input on the TV.

What type of video output are you using on your PC? HDMI,DVI,DisplayPort?

My latest PC (i7 4770, Gigabyte mobo) can output UHD via HDMI 1.4. I haven't connected my PC video output to the TV yet.

Currently I'm using Display Port, however that's not an option with using a TV as they are all about HDMI.

So I would need to look into an active adapter between DP and HDMI - as well I would be looking at the upcoming release of new GPU's from Nvidia next month to see if they will support HDMI 2.0 (therefore I would go with HDMI rather than DP)

When I built my latest PC, I used onboard graphics from the i7. It surprised me that it supported UHD. The Gigabyte motherboard also supported UHD but only at 24 HZ. When I bought the TV in Feb. there were no GPUs available with HDMI 2 outputs. I understood that they would be coming soon. I'm going to check too and maybe add one to my PC. Right now the output from my PC is limited to the 24 HZ coming out of the mobo which my TV doesn't support. With a separate GPU, I'm sure I could go to 30 and 60 HZ. The TV supports those frequencies.

Here`s a link for 4K test material, encoded in H.265.

The clips playback fine using the LG 55UB8500.

Thanks for the link. As I stated before, I believe that my 2013 Sony UHD TV can't play any UHD files no matter what the format. It handles the UHD signal once it is converted to a displayable picture ie. 3840x2160 at 60HZ. Apparently Sony says that the TV requires additional hardware/software to read these files. I still find it hard to believe that a firmware update couldn't handle the reading of the UHD files.
