LG's 84-inch 3840 x 2160 Television Doesn't Come Cheap: $17,000 152

An anonymous reader writes "LG held a big launch party today for its highly anticipated 84-inch Ultra HD TV. The launch was held at Video & Audio Center in the L.A. area, which sold six sets within two hours. The MSRP had been set at $19,999 but we now know the street price: $16,999. 'My wife would rather I waited,' said one of the buyers." The article claims a couple of times that "Ultra HD 4K" has ~4000 vertical lines of resolution, but that's not true: the (unimplemented?) 8K spec is the one with 4320 lines of resolution confusingly enough. In any case, that's a lot of pixels. Maybe this means we'll finally see computer monitors break through the "HDTVs are the dominant consumers of LCD panels" barrier of 1920x1080.

      That's not normally how "lines" is interpreted. A "line" is generally expected to be the same as a "row". Each line is 4000 pixels long (well, actually 3840 pixels), but there are only 2000 (really 2160) rows. 4000 refers to the columns. I guess we could start referring to 1080p as 2K, 720p as 1.5K, and 480p as 1K, but since we already have the row-based naming convention it seems silly not to call this 2160p.

      • Last I checked, a line was a straight thing, with ends that went in any direction it liked.

        • He's talking about the contextual meaning. In the context of video displays, 'lines' go from left to right, as that's the way CRTs TVs scan, one horizontal line at a time.
          • Or, I should say for clarity, a single 'line' goes from left to right, and the 'lines' are stacked vertically. So the number of 'lines' gives the vertical resolution.

        I'd be careful about this, since "vertical lines" in the context of TV traditionally meant something different than what you probably think it means. If you want to display a picture of a series of vertical lines, you need at least twice as many pixels, as per Nyquist–Shannon sampling theorem. This is why 8K (8000 pixels horizontally) can display 4000 vertical lines and 4K (4000 pixels horizontally) can display 2000 vertical lines. (The term is a little bit antiquated, since it was used for measuring

      While it's true passive 3D requires 2x horizontal lines to get the same resolution, that is so far from the reason 3D has failed in the home market it's barely even worth mentioning...

      • 3D doesn't add that much for TV's. 3d works best when the TV takes you entire field of vision. Most TV's are placed 8-12 feet away from the viewer, so they get a smaller field of vision, and 3d isn't as immersive.

        Also people don't watch TV as intensely as they do a movie. When watching TV you are more often than not distracted, doing other things, talking to other people. Getting up... 3d with glasses doesn't allow normal TV viewing habits.

          Yeah, that was actually my point - passive 3D uses horizontally polarized lines on the screen so technically it's interlaced (540 lines) for each eye - but that's not the reason 3D in general has been such a bust.

          The reason is partly as you say because it's not that great an experience at home, partly because wearing silly glasses at home sucks, and partly because most 3D content is just plain awful. I've seen maybe 10 movies in the theater in 3D and only 1, maybe 2 were actually enhanced by the experience

    ...for average use in the home 1920x1080 (1080p) *resolution* is not the problem for a ~60-70" TV (still considered high end!) from 10' away. The limiting factor for quality is still the encoding rate for anything less than BD bitrates. So, for anything other than physical media 4K is not even remotely practical, and even for physical media it's such a diminishing return few consumers will care. Combine that with the fact physical media is in decline and I don't see 4K adoption any time soon...

    • Is there any content in such high resolution available?

      Regular blu-ray is 720p or 1080p. And I'm not aware of higher-resolution physical media.

      The only source of such high-res content I can think of is cinema-type media, and I don't think those media are so easily accessible by consumers.

      • by Dahamma ( 304068 )

        There really isn't anything displayable on a TV with available hardware that I know of - probably the closest a consumer could get is something decoded on a PC with mulit-monitor and/or special hardware.

        And what's even more telling is that most digital theater projectors in use are still 2K (2048x1080) - and in fact a lot of (new and old) movies are still digitized at 2K, so there may not even be 4K sources for most current movies anyway.

        • Too lazy to search but I do expect that the higher-end video cards have no problems decoding such resolution. And modern quad-plus-core processors are commonplace nowadays. At least nothing someone who is happy to put down $17k for a TV won't be able to afford.

          The problem will be the content itself... maybe 2K is just good enough? Or at 4k the file sizes become prohibitively large?

          • by Dahamma ( 304068 )

            With multiple video cards, maybe.... (this would basically be displaying 4 1920x1080 screens). Possible but seriously not mainstream.

            But yes, why bother without the content. A BD averages 25-30Mbps. Multiply by 4 and that's over 100Mbps. That's 90GB for a 2 hour movie. Gets to be pretty large... [also compare with the highest end 1080p streaming from a service like VUDU of up to ~9Mbps or 8GB for 2h. Would be 36Mbps / 32GB for a 4K movie, which is way beyond most people's home Internet connection, o

            • A properly encoded movie (not low compression like MPEG) is more like 5-10 GB for a 1080p movie. So 20-40 GB for a 4k resolution. A lot but not too bad.

              Oh and not everyone lives with those silly restrictions on Internet... in HKG many homes can get up to 1,000 Mbit nowadays. So 20-40 GB is no problem, a minute or two downloading on that speed. It's the availability of content that's probably the biggest issue.

              • by Dahamma ( 304068 )

Thing is, there is not a lot of motivation to bother with 4K at a compromised bitrate when you could do 1080p with no noticeable artifacts, and most people can't tell any difference.

            The problem isnt the processing of that number of pixels, its getting content that uses it. For instance, HDMI 1.2 and earlier support a maximum resolution of 1920x1200 at 60 FPS

            HDMI 1.3 (June, 2006) maxes out at 2560x1600 at 75 FPS, and HDMI 1.4 (May, 2009) maxes out at 4096x2160 at 24 FPS. Note that the signal rate of both 1.3 and 1.4 are exactly the same, so all that changed was supporting more pixels at the expense of a lesser frame rate.

              The HDMI 1.4 specification wasnt even finalized until 2009, so nobody was even considering producing more than 1600p before then, so good luck finding > 1600p content.

              And when they moved from NTSC/DVD to HDTV/BluRay, none of that old content was available in HD.... oh wait, it was. For example here [sony.com] is a list of some of the 4K Digital Cinema releases dating back to 2004. Granted, it's probably not that many but the lack of a 4K consumer standard didn't stop them filming in 4K.

    • Indeed, 20/20 vision dictates that at 10 feet we can see things 0.875mm apart. That means that 1080p is enough for anything up to a TV 1680mm by 945mm – that's 1927.5mm diagonal, 75 inches. Given that the ideal angle from corner to corner (according to the THX spec) for a screen is 36 wide, and at 10 feet, a 75" screen makes a 34.7 angle, we're already pretty much "there" – there's really no reason to double resolution at this point, other than epenis waving.

          Does the definition of 20/20 vision really mix imperial and metric units?

What most people would call an ideal seat in the middle of the cinema is well in to the 40s with the closest seat - which most people find too close - over 50 degrees. Then again that is also because those seats are so far down so you have vertical issues looking at the screen, but no doubt there's a thing as too close.

      That's really where an improvement is needed, not the number of pixels.

    Just Scan (1:1 Pixel Matching): HDMI: 1080p/1080i/720p, Component: 1080p/1080i/720p, RF: 1080i/720

    If I'm reading this correctly, the TV doesn't actually support anything higher than a 1920x1080 ("1080p") signal input. So while it might in fact have a 3840x2160 panel, that panel is absolutely worthless, since it has to upscale everything that's being displayed.

    The Chinese produced [wikipedia.org] a 77,460,000 x 50-pixel display ages ago to lock their competitors out of the marketplace. Eventually you get to a point where you can't see the whole thing from land, and you can't see it from space, so what's the point? All the pixels were stuck anyway, and whenever you lit it up there'd be smoke!

    Costs have really come down, though. By some estimates, 1 million workers gave their lives building it. That's 3,873 pixels per life. Foxconn's averaging several trillion pixels per life these days.
