    How come DVD players boast of 10 bit resolution per channel,
    presumably lots of engineering effort went into achieving this?

    People pay a premium for this and ask for it. Video cards for PCs
    output 8 bits per channel.

    Then they connect it to a LCD panel where you need insider information
    just to find out that it's a 6 bit per channel display. Which most
    are.

    So why are companies on one side lying and hiding information about
    the true performance of their LCD products, but other companies
    produce specs and hardware that can never ever be used fully?

    And what the hell is the deal with "HD" panels with oddball
    resolutions like 1366x768 or 1440x900? Is there like a backlog of 12
    trillion gate drivers that can only handle 1366x3 pixels that people
    want to use up?

    Whhyyyyyyyyyyyy????

    It's like if CD players only played back 12 bits per channel at 22KHz
    sample rate, but all the studios released 24 bit/96KHz SACDs, and
    everyone claims they can tell the difference.

    Same reason hotdogs come in packs of ten, but hotdog buns come in
    packs of eight.

    Square bread, round bologna.

    It isn't _supposed_ to make sense!

    I'm not a fan of it myself. Humans don't see in letterbox vision.

    That's not what I mean. HD is supposed to be 1920x1080. People are
    going to pay for HD-DVD or Bluray discs, in effect buying all their
    software again, but there are precious few monitors or TVs up to the
    task of actually displaying the pixels you paid for!
    It's like my CD example! Argh!

    It can be rescaled to anything you like.

    I'm actually seeing quite a few of the large LCD panels sold for
    television monitor use at 1920x1080 (or x1200 or whatever) these
    days. I've had a 1920x1200 display on my 'puter for about three years
    now. They're available if you look for them. But IMO, there's
    precious little content that's worthy of that sort of resolution.

    Cheers,

    Er... what is it exactly that you can't see with your "1366x3" pixels? Fleas
    on the dog? Everything that the director meant for you to see you can see.

    The pixels I paid for on HD DVD or Bluray or whatever?
    So, I take it you'll want to buy a few of my 12 bit, 22KHz CD players
    then? What is it you can't hear with 12 bits 22KHz? The fleas farting
    on the dog?
    And why did you put 1366x3 in quotes? Do you not see that something
    has to drive 1366 red cells, 1366 green cells and 1366 blue cells for
    a total of 1366x3?

    AFAIK studies have shown that the ears have capability to resolve
    phase differences to 100KHz, and the headbones do vibrate well above 20KHz.

    ....And you will probably find that they are 6 bit displays, and/or
    they use backlight trickery to achieve their enormous contrast ratios,
    in other words it's hype.
    Sometimes you'll even see 1920x1080 LCDs that will only work with HDCP
    enabled sources, and if you try to connect a VGA "in the clear"
    signal, it'll only display 640x480 max or some such idiocy.

    Welcome to Windows Vista *mandated* DRM hardware and software (tail
    wagging dog BS).
     
  12. Vista is only one of many. If you are using commercial
    hardware/software then stiff shit, deal with it or install linux on
    you hd-dvd player/playstation
