    I've finally got round to mounting the pj permanantly and need to know whats the best way to ensure that the mount for my PT AE100 is exactly in line with the screen.

    Surely there must be a tried and tested, dead simple way...............;)

    I mounted my PJ first, I then squared up the image by eye onto the wall, I then measured the sides of the image to make sure they were equal, when it all measured up square I marked the centre line onto my wall in preperation for mounting my screen.
    Hope this helps.

    I've not used this method because my eye tells me my guesswork was pretty much bang on, but hear goes....

    Get 2 long pieces of string and attach 1 to each side of your screen. Where the ends of the string cross near the projector is the horizontal middle and ensures everything will be evenly in focus. The vertical middle can then be assumed to be right at the point where you need zero keystone adjustment for the image to fit perfectly inside the screen frame.

    I think that's right! hope it made sense.

    To set height dead on.
    Go to local hardware store and buy some clear plastic tubing.

    Take home, lift the ends up (one next to projector, one next to screen) fill tube with water, and the top of the water in the tube will be at exactly the same level either end,

    (you've made a long custom spirit level)

    Now you can get heights spot on :D

    Is there a recommended height off the ground for a screen? Centre-line of image at the same height as your eyes when sitting at the viewing position, that sort of thing?

    You hear so much medical health and safety chat about computer monitor positioning, I'd be surprised if there weren't similar guidelines for projection screens.

    Of course it's really a matter of personal preference, but I'd be interested to know if there are any guidelines - or if anyone's found themselves adjusting their screen position after a while for watching comfort.

    Thanks in advance.

    I try to get the centre line of screen as near to eye level as possible. With large screens you tend to have to go higher though. Also ceiling height and projector type can affect just how good a screen placement you can have.....

    Gordon, thanks for the speedy reply. I suspected that centre-line-at-eye-level might be a favourite.
