Following the recent announcement from LG for an 84-inch 4K Ultra Definition 3D HDTV, Sony is also up to the 4K game as they have announced a similar product – Sony BRAVIA KD-84X9005. Sony is also going to release an 84-inch 4K resolution passive 3D HDTV like what LG is going to start offering in September, however Sony should have their product on the market by the end of the year. The 4K (3840×2160 pixels) LCD HDTV from Sony will also be equipped with HDMI 1.4 interface capable of supporting the panel’s native resolution in 2D mode, but not stereo 3D mode higher than 1080p. So you’ll be getting Full HD 3D support as maximum over the HDMI 1.4 interface that will be upscaled to 4K by the TV set. The fact that the 3D is being achieved with passive 3D technology however will make it possible to use Row Interleaved output to the display to have 3D content at 3840×1080 resolution per eye in stereo 3D mode at 24, 25 or 30Hz, so no the 60Hz that some of you might expect as we are hitting the HDMI 1.4 interface bandwidth limit. So don’t be i a hurry to be an early adopter of 4K 3D HDTV if you really want to be able to fully enjoy the higher resolution in 3D as well, though there is still total lack of consumer accessible 2D and 3D content at 4K resolution anyway.

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.
