    Can anyone please tell me how to figure out the vertical lens offset for the X1? I need to know if it will work in my room with low ceiling, 6'8" tall. Thanks.

    I haven't got any figures to hand but from memory the X1 would be level with the top of the screen for ceiling mounting and level with the bottom of the screen for table mounting.

    This is from memory only and makes quicker sense than the above link.
    If the picture were 10 foot high in 4 by 3 mode there would be about a foot between bottom of picture and lens. A 5 foot picture would therefore be about 6 inches.

    In 16 by 9 mode, picture is in middle of native 4 by 3 chip, but I cannot remember what this means in real numbers. But, basically, first answer has it just about right.

    Ok here's the spreadsheet calculator that will provide the answer you are looking for, its for the SP4800, but that shouldn't be a problem (same machine)

    Not the most user friendly Spreadsheet (Excel) but it works - hope this is OK, althoough I've done some changes to the sheet I have not changed any of the screen dimension calculations :thumbsup:
