In addition to OLED displays, Samsung was also showing off their prototype 25 lbs thin LCDs as well as their 82" 3840x2160 (4 times 1080p, AKA 4k) display. They also showed off a technology called Reactrix WAVEscape. Sensors mounted above a TV can detect a person's movements and react accordingly. Samsung reps went as far to call it a Wii without the need for a wiimote. This technology will be used by Hilton hotels this year for interactive maps and in conference rooms.

    Sony calls their SRXR110 projector a '4K' projector, because it's larger dimension is 4096. Although it's unclear if they mean '4K' because of the 4096, or because it is "more than four times the resolution of full HDTV."

    [url=">]Digital Cinema[/url] seems to use '4K' to refer to the horizontal resolution, so Sony's usage would be 'correct', and this one would be a little short of 'true' 4K.

    Actually, this is incorrect, the resolution designation is taken from the lowest directional value - 2048. So this is actually a 2K display. Even so, this is a formidable achievement. Westinghouse started offering a 2K display last year, for $50K. What's price on this puppy?

    I'm guessing a little here, but I think 4k is correct. The number of pixels for a 1080 display is 2073600 (1920 x 1080), and the number of pixels for this display is 8294400 (3840 x 2160), which is four times the number of pixels of a 1080 display.

    The original referent is to movie technology, full screen 35mm resolution analogs to a digital resolution of 4096 dpi- vertical, hence 4K. since this is 2048 (OK, 2160) it is 2K. The obfuscation is made by the Samsung marketing department who would dearly love us to believe that they have achieved movie quality already... not just yet boys, but 2K is still pretty impressive. My next question is: what's the framerate? Hopefully at least 60fps and also please, please use a 5:5 pulldown...
