Snaphook and abirdie4me seem to be very happy with this choice of PJ but I have some questions regarding their setup.
If I put Snaphook 's setup in to the Panasonic throw distance calculator (11'x7' screen size, 13' throw distance, 9' projector height), then with the maximum -44% vertical lens shift, the bottom of the image would be some 2ft off the floor.
Presuming that one wants the image to be displayed to the floor, this suggests to me that the PJ is tilted downwards (about 6.5 degrees).
Is this correct or have I completely misinterpreted things?
If correct, does one then use keystone correction to square up the image?
If so, is there much of an impact on image quality? I suspect not for this correction amount and that we are talking about a sim rather than a HD video.
I'm intending to project an image of 13.5ft wide at 16:10. This means a minimum throw distance of about 15ft.
I need the PJ to be at about 9ft to avoid the garage door killing it and to be able to hit from about 10ft out. I'm 6ft tall so I think this avoids shadow issues - at least according to my trig calcs.
I'd then only need about 3 degrees tilt to project image to floor.
Please let me know if I'm on the right track or not.
Thanks a lot!
Mike
