LG Has Announced an 84-inch 4K Ultra Definition 3D-capable HDTV

August 22nd, 2012 · 11 Comments · General 3D News

Today LG has officially announced what they call the world’s first 84-inch Ultra Definition (UD) 3D TV for the Korean market with the TV expected to start appearing in North America, Europe, Asia, and Latin America starting in September. What is interesting here is the fact that you get 4K resolution in 2D mode and more than Full HD in stereo 3D mode since the 3D TV set uses LG’s passive (FPR) 3D technology that essentially halves the vertical resolution in 3D mode. And the good news is that the 4K resolution (3840×2160) is actually fully supported by the HDMI 1.4 interface and thanks to the use of passive 3D technology you can also use the interface in 3D mode as well, though you’ll have to feed the TV set with Row Interleaved video data directly as HDMI 1.4 does not currently feature frame packaging support for more than 1080p resolution.

The 84-inch LG 84LM9600 Cinema 3D TV is definitely an interesting approach from LG as the company is clearly targeting to get a good market position among the 4K resolution TV sets even though they are still very far from becoming mainstream. And the good thing is that even the currently available technology allows them to support stereo 3D mode, though not in the full 4K resolution, but with more than enough pixels at 3840×1080 per eye for the 3D mode. 4K stereoscopic 3D support with active 3D TV sets at this time would be a problem due to the very high bandwidth requirements in order to push two frames at full 4K resolution, but with all the interest in 4K we are probably soon going to get a new revision of HDMI supporting frame packaged 3D at over Full HD resolution. The good thing from all this is that we are probably also going to have support for 1080p 60Hz frame packaged 3D mode sooner than later, so while 4K TV sets at every home is something still in the not so near future, we may all benefit from that even in the next generation of Full HD 3D-capable solutions.

    This is a step in the right direction for Passive 3D. LG is clearly digging in to make Passive the dominant technology. But what happens when Active TV manufactures get 4K? The passive at 1/2 resolution argument will still hold true…

    besides pc games, what actually runs at 4K?

    Not much content in 4K available to consumers yet, that is exactly why LG has also provided an upscale functionality in this TV set. Not to mention that in order to run a game at 4K resolution you’d need a pretty powerful hardware, especially if you also want to render it in stereo 3D mode. 4K in 3D is actually even more demanding than running 3x 3D monitors in a 3D Vision Surround setup…

    Calling it “4K” is a bit misleading. It should technically be called “2K” since it is 2160p.

    Not really as the industry uses the number of horizontal pixels for getting the 2K or 4K naming of a resolution instead of the vertical number of pixels…

    So why do current HDTV’s list having 720p and/or 1080p? I am not trying to argue with you but I just think it is misleading.

    Once the prices drop I would be interested in seeing how these look with passive 3D however.

    At these resolutions I think it will be a competition between passive and auto-stereoscopic rather than what we have seen with active vs passive.

    Active shutter at these resolutions might die out…thoughts?

    Excellent! Hopefully this will spur developers to work on native interlaced 3D support.

    I was looking at an Epson 4K projector in one of the stores locally and it looked amazing. It also interpolated the 1080P signal. (Not 3D though). This is a game changer.

    If I am correct the current AMD 7XXX series can do HDMI 1.4a 1080P @ 60FPS per eye. Does this panel have the matching receiving chip?

    Any idea on price ? I had heard $10,000 USD a while ago

    The price is OVER 9000 hcforde.

    As for AMD’s 7xxx series doing HDMI 1.4a, it’s all a matter of tri-def support at this point, since AMD themselves really don’t handle anything on the 3d side of things. Generally speaking, that’s why I practically always advise NVidia over AMD when it comes to 3d.

    Yes I am well aware of their “OPEN” approach. There are pro’s and con’s to both sides. I currently have a GTX470 & 2GB HD5870 crossfired along with the equipment to do S3D with both cards. However, as I understand it there has to be the transmitter chip the drivers and a receiver chip for it all to work at 60HZ per eye. I see Tridef addressing this long before Nvidia.

    The biggest issue is how many people will buy these for the purpose of playing S3D games on them at these prices and will there be a demand for Tridef to address it. There are some native games that are S3D and with the Windows 8 platform this might make it a bit easier
