    Why Matrox and not a Projector?

    Hi,


    i just saw all these posts for the Matrox 3 monitors solution and i'm
    wondering why you prefer this solution than a 1024x768 projector with the
    same money?

    * Almost all the projectors from 3meters give a wide screen about 1,8m, so
    you can also make the zoom 0,50

    * Also you can use it in every hardware change (new PCs and FS), without
    waiting new drivers

    * And at the end no radiation.

    Just need to know you opinion, today i only have one monitor for external
    view, but in the feature i was thinking to buy a projector.


    regards


    Eddie

    I suspect mostly it's the space needed. Ideally I'd have three screens with
    three projectors driven by the fastest Parhelia I could get!

    Incidentally, I do have a good projector with my 737NG cockpit setup, but
    only the one, and it's cost far exceeded the cost of a Parhelia and three 18"
    TFTs (more than 3-fold in fact,more counting the screen). But maybe I'm
    rather fussy? I wanted a 10' wide image in a room not long enough, so had to
    pay a *lot* more for a wide angle lens for the projector.

    Then there was the little matter of resolution and brightness. To be really
    as effective as a monitor, projection really does have to be very bright,
    and this adds to the cost. And to compete with Parhelia 3 screen resolutions
    of anything from 2400x600 to 3840x1024 is hard to do with cheap projection
    as well -- mine gives about 1400x800 (approx, figures not to hand) in 16:9
    widescreen mode, which is good.

    Horses for courses?

    Hi Peter,
    What is finally the distance between your projector and the wall to obtain
    your image and what size does it has ?

    Many thanks

    Lens front to screen is about 13' (4 metres) and the screen image is 10'
    wide, exactly (3 metres) with a 16:9 image being used.

    The projector could have been a little closer or a little further back -- it
    is an Hitachi CP-SX1350. The lens is a zoom wide-angle lens with vertical
    shift capability, very expensive. There is an even wider lens which would
    allow me to get the projector as near as about 9 feet (2.75 metres), but that
    lens is fixed focal length, not zoom, so would require much more precision
    in its ceiling mounting, and at 9 feet it would be high over the cockpit,
    very difficult to reach if ever needed.

    The advantage of getting the projector nearer (apart from, in my case,
    avoiding having to make a big hole in the rear wall to accommodate it using the
    standard lens!) is that the cockpit itslef (with its roof sporting an
    overhead panel) can be put nearer the screen, for a wider-looking result. In my
    case I managed to get it with the pilot's eyes some 6-7 feet from the screen
    without the cockpit roof casting a shadow on it. This is only possible in
    16:9, which is why I changed to it.

    Lok at the cockpit -- it is not home-built, I am no good at such things -- it
    is the PFC 737NG, www.flypfc.com.

    Regards,

    Pete

    Hi Peter,
    Thanks a lot for all the info. I still have to decide on my visuals -
    very informing.

    Nice cockpit setup from PFC for the B737. Honestly I don't like the
    building too but I have to do it for my B744. I prefer to fly the
    thing, not building it
