Can't wait to set it up. I'm replacing a short throw Optoma GT750 which has served me well but it's only 720p. I have a 10" duct giving me hell about what projector I can use to get my 100" image and I've been waiting forever for a 1080p projector to fit my dimensions. This one gives me 3" of breathing room behind the PJ with the lens 8'4" away from the screen. 100" image and I get to use my 3d blu rays I could use with my GT750! I'll try to post a few pics of the setup when it is done.
Yes, that appears to be correct. My calculator seems to have an issue doing that small amount of shift due to the graphic of the slider. I'll have to fix it later in the next update, but for a 100" 16:9:
Minimum Offset of w1070 = 2.5 inches above or below
(approx 62 mm)
=5% of 50" screen height = 2.5" / 1/2 for center = 1.25"Maximum Offset of w1070 = 7.5 inches above or below
=30% of 50" screen height = 15" / 1/2 for center = 7.5"
This would make sense since my Benq w7000 can be mounted about 6" above a 100" screen, and Benq calls this 125% of vertical lens shift
(of course my projector's offset is center based so I have a lot more play).
For the w70000, the maximum offset is therefore 6.25" instead of 7.5" (25% * 50" = 12.5" / 2 = 6.25")Edited by coderguy - 1/13/13 at 3:52pm
