    Hi people, long time reader first time poster.

    I have just invested in my first projector and wanted to know a little bit more about screens.

    I have done a search through past threads for info on screens and drew a blank.

    I have ordered a HW-WALLSCR84 (Infocus Pull-Down Screen).

    I am wondering if this is a good screen.

    and also what are the screens made of?
    and what difference in picture different screens make?

    It is to go with a HP VP6110 (1500 Ansi Lumens, 2000:1 Contrast ratio) I wanted an X1 but unfortunately stock levels are not good on these and it would have taken nearly 2 months to arrive.

    Thanks in advance,

    Cheers,
    Josh

    Welcome Josh. I am not familiar with that particular model of screen, there are hundreds.

    A screen is equally important as the projector is. Once you decide on a projector then you must "match" it with an appropriate screen with a gain that will benefit not only the projector but the room it is placed in. Screens come in various gains from 4.0 and beyond. Too high a gain could yield hotspotting and too low a gain will result in a dim image.

    I would like to know what the real-life specs for the HP are just for curiousity... ie, when it is throwing out 1500 a.l. then what is the c.r. and to achieve the 2000:1 c.r., what is the brightness.
