Hello,
Just looking into this problem. When I went to projectorcentral.com and used the distance calculator it came up with the values as described in my orginal post. However, not thinking it would be different, I went to
http://www.optoma.co.uk/distancecalc.aspx
and the values are coming in at 2.13m to 2.46 for a 166cm diagonal screen. This would be possible to fit in my room. But the projector would still be much lower than the screen. Approx, 1m lower. Would this be a problem?
Also, can someone please confirm because a couple of sites differ from the Optoma values.
Regards,
Prakash
