    I've been looking at Plasma and LCD tvs and have noticed that ther
    are variations in the contrast ratio (1000:1, 3000:1, etc.) and th
    resolution. I understand how resolution numbers work with compute
    monitors but wasn't sure if it was much of the same with a TV. I'
    guessing that the better the resolution on the TV, then the mor
    crisp the image will be

    Also, what is factored in when looking at a contrast ratio on
    certain TV? How do the variations affect the screen image? The highe
    the better

    Any information would be helpful. Thanks

    Unless there is some fine print that says exactly how the contrast ratio
    was determined, consider it just a "marketing number" that somebody
    thought sounded good. There is probably some value in the number when
    used to compare similar products from the same manufacturer.

    There is an ANSI standard method of determining contrast. There's also
    one for measuring brightness. Don't assume that a gadget that's "3000
    ANSI lumens, 2000:1 contrast ratio" has measured both the brightness and
    the contrast using ANSI methods.

    These numbers are supplied by the manufacturers and normally are used by the
    consumers to compare relative items before purchase. However, as stated, the
    measurement procedures implemented by each company may very. Best
    recommendation is for the prospective purchaser to physically compare items,
    preferably without the intrusion of a high pressure salesperson being
    involved. Then making an educated selection before dropping the quid on the
    telly. Trying to do this via the internet, in sales brochures, etc normally
    ends in dissatisfaction in the opinion of the end user.
