    If you mount the projector 200mm from the ceiling it will be 300mm above the level of the top of the screen. To see if you'd be happy with the effect of the amount of Keystone required, position the projector 300mm below the level of the botom of the screen (on a coffee table/whatever) and adjust it so that you get a picture with vertical sides. Then you'll see how much Keystone would be required and whether you think the picture is degraded. Generally, Keystone does disort and degrade the picture, but it depends on how much you use and whther you're picky/sensitive about the effect.

    BTW, did you write telegrams as a profession in a previous life?.............. unique posting style.... :D
