dark display of video. Can a LCD monitor improve this?

    I'm told that the video is darker when displayed on a computer monitor
    compared to a television.
    If I were to change from a CRT type monitor to a LCD monitor would the
    video still be dark on the screen?

    Depends on how you adjust the brightness.

  3. If it uses the same gamma curve, (likely IME) yes.
    Why do you ask? Perhaps that is not the right question.

    I'm asking as I'm thinking of buying a LCD monitor to replace my old
    CRT monitor. If the brightness of the picture improves then it may be
    worth the extra money for a LCD monitor..

    Brian,
    I just did what you want to, when my LCD monitor arrives and I hook it up,
    I'll let you know
    my opinion. I have read online about how whites are generally brighter on
    lcd displays over crt.
    But it wasn't listed as a good thing for graphic artists, something about it
    being too bright.
    I am pretty sure it will do fine enough for our purposes. :)

    Good Luck,
    AnthonyR

    Your video card's drivers should have settings for video overlay.
    Adjusting those might fix the problem on your CRT monitor.

  7. When you say "video" are you talking about computer-
    generated display, or actual video as in 25FPS television
    signals?

    oh you just want to justify the cost of getting a slick, thin screen. Well
    go on, indulge, happiness is the only excuse you need.

    Seriously, a do a bit of editing and have a dual screen card, recently I
    replaced one of them with an LCD monitor.

    LCD monitors change depending on what angle your looking at it - so you need
    to be front and centre to get a good image. Great for personal use, not so
    hot for presentations.

    The contrast is very good - great for reading. Whats not so good is
    dithering isn't as effective. An image thats stretched to fit the screen
    that looks fine on a CRT display will look blocky on my display. This will
    be something to get used to, especially with low res video.

    It makes moving the computer a breeze, and there's so many more places you
    get use it.

    If you do any recording, an LCD screen has far less interference with guitar
    pickups.

  9. Yes, as well as washed out and faded with hardly any contrast. The ONLY
    advantage an LCD has over a CRT is form factor. It suffers dramatically in
    all other comparisons.

    I don't understand what you mean by "form factor".

    I'm talking about displaying a video (such as an mpeg or avi file)
    using a video editor program.

    Thanks Terry.
    But what I'd like to know is does the the LCD monitor display the
    video as a dark picture?

    Form factor refers to the physical characteristics, such as size,
    shape, and weight.

    Yes its still a dark picture. What you may be noticing is devices that
    output for television can add 'setup' which is they brighten the blacks and
    dim the whites. (So some pictures will appear brighter on your screen as
    well.) Screens are better with that extra contrast as it makes it easier to
    see details and read.

    Bear in mind most graphic cards come with software controls to adjust this -
    so it may be you need a brand of card with a better control panel.

    LCD's have terrific contrast. This may strike someone as being brighter
    because they notice things they won't see on a crt. For example a white dot
    on a black background on a crt may be seen as a grey blob. But on the
    flipside, what is a blurr on a tv often becomes a horrific mess of grey
    pixels on a LCD. So if its a movie watching experience your after perhaps a
    larger crt or a newer graphics card is what you really need. But if you
    need to observe minute detail, perhaps for a study, then a LCD would be a
    better choice.

    I agree as one poster put it, the form factor is its major benefit. If it
    was just as bulky as a regular screen there would be no reason to purchase
    one. Buts its thin and light and can go anywhere.... and thats soooooooo
    coooooooool.

  15. It is more the dramatic difference in gamma curve in TV vs computer
    displays that accounts for why video looks "dark". Same with CRT or
    LCD.

  16. "form factor: The physical size and shape of a device."

    Google is your friend.

    I don't that is a good reason for going LCD - the quality of the pic on
    LCD will dpend on which one you buy - if you pay the big money and go
    Apple LCD you will get superb results - go cheapy, like my LG LCD and
    you get an OK pic, but one that doesn't even come close to a good Apple
    CRT monitor, but about as good as an el cheapo CRT like my Daewoo 19"
    CRT monitor.

    I run the LG LCD (on my Mac) and the Daewoo CRT (on my Windows crap)
    side by side - overall not a lot of difference excet the LG is sharper,
    but the Daewoo has better colour.

    I have a KOGI LCD monitor and it's definitely darker than a monitor.
    Just not enough contrast ratio on my particular monitor.
    If you get an LCD, make sure it has a very high contrast ratio.

    I can watch a movie on my LCD and some are so dark, I can't tell what's
    going on, whereas it looks fine on the TV.

  19. Computer displays have a very different gamma curve than
    video displays whether you are talking about CRT or LCD.
    Video will always look "dark" on a computer display unless
    you apply appropriate gamma correction.
