I'm looking at the Epson 6020, and I'm planning to use a UH480 A-lens. I'm planning to mount it to the ceiling, but I'm not sure how low it needs to be. I have limited headroom on my riser, so I'd like to keep it as close to the ceiling as possible. I'm planning for a low profile coffered ceiling (somewhere around 2.5"), and I have a soffit that will be above the screen. How do I determine how low the PJ needs to be so that the image is not obstructed by the coffers or the soffit?

Thanks in advance!

Dude, are you made of leprechauns? Cause that was awesome!

You may want to try your question in the EPSON 6020 Owner Thread.

Thanks, Mr. G. I suspect it comes down to geometry. The more I thought about it, the more I decided I was making it more complicated than it needed to be smile.gif
