    Hi there. I need some tech geeks on here to help me explain some thing about this projector. I would appreciate some LINKS to further explain the answer to my question.

    QUESTION:

    The 4805 is NOT an HD projector right? wrong? I am guessing (with my limited knowledge) it is not. NOT for $1500 or less. So what is it? What makes a TV or Projector High Definition?

    Thanks!!!!!!!!!

    John, the 4805 is NOT a HD projector. It is a 480p projector, which is the same resolution as a DVD and standard satellite TV. It will accept a HD signal(720p, 1080i) and scale it to 480p in the projector. It will not display a true HD image, but it looks really nice, better than a DVD. A true(native)HD projector is 1280X720(720p).
    Are you looking to buy a HD projector?
    What is your budget?
    You can buy a 720p LCD such as the Panasonic 500 for less than $1500. The Sanyo Z2 is just over $1500. The 2 that replaced those, the 700 and Z3 are about $2000.
    Go to Projectorcentral.com and read the "Highly Recommended Projectors", and other basic info.

    I recently purchased a 4805 and could NOT be happier and all my friends and relatives are jealous!!

    I just did not know how to explain to them in simple terms (since I am a newbie) that it is not a true HD projector. Thanks Jim!!

    If anyone else can give me links to other sites that explain this in detail or add more to what Jim said, I would appreciate it!!

    I'm trying to search for info myself but help would be good!

    John, the simplest way to describe HD, whether it's a TV or projector, is with how many lines of resolution. Standard TV is 480 lines of resolution. HD is 720 or 1080 lines of resolution. The more lines of resolution, the better the picture. PERIOD.

    Only true if all other aspects of PQ (brightness, contrast, etc.) are equal. There have been several studies that indicate that contrast actually influences perceived picture quality more than resolution.

    how is the PQ on the 4805 versus a large RP-CRT like a 65" or so?

    if you dial down the 4805 screen size to about 84" or so are they are close in picture quality for dvd's ??

    which looks better for dvd's in a totally dark room??

    (assuming both are setup and calibrated properly)

    Well I have not done the comparison you mentioned above but I have mine hooked up to a Zenith DB318 (read up on these too!!! [​IMG] ) upscaling dvd player and the picture is amazing, IMHO. Once my soon to be home theater is up and running in January or so I plan on having it calibrated so the colors should really be stunning. You might try AVSforum.com, they have a more extensive pj area and one hell of a big thread on the 4805.

    The question is, does an HD feed on this entry level true HD projector look better than on the SP?
