I didn't see where Docj04 listed his working screen size, but I have a 5040 running a 181" + borderless image onto a Painted ALR Drywall surface. The surface has been smoothed to a exceptional level, and while the ALR Paint is a very dark Gray shade, because of it's components (Silver-Pearl-Polyurethane) and being sprayed via HVLP, it exhibits no "Graininess while having appreciable gain. But most telling is the surface's ability to render a extremely dynamic image with a almost 3D-like depth even at 181" diagonal. I estimate I'm getting 24 ft Lambert, which is blazingly bright in a dark environment.
Here are some revealing screen shots.
A shot in ambient light and
Same shot w/no Flash in low ambient light - straight on...
This shot reveals the screen size in 16:9 mode...
and a few "In the Dark" examples....
Sorry...no Football, but I can state irrevocably that Satellite imagery is even more intensely bright.
The coating used can also be sprayed directly onto any smooth, conventional Screen material (Silver Ticket / Carl's Flexi-White) or any other smooth, white material, so Docj04, just shoot me a PM and I'll set you up with the method / materials required.

I just measured mine and it's about 3 1/8" from the ceiling.
I have been an advocate of the Chief Mounts (RPA-Dedicated) for quite a while, and when using the Dedicated Stamped Plates, and a ultra-short Drop Tube (4" long PVC)through the ceiling I could get the distance down to 3.5". Smarty, to get 3 1/8" you must of screwed the main component directly to the Ceiling, but even with that, the current Universal Mounting arms are much less desirable and of a higher profile than the older "Channel" arms of the RPA-O.
Since Chief has not yet released a RPA-Dedicated "Stamped Plate" for the 5040, I decided to switch to the Peerless Universal (w/Channel arms & Cam Adjust.) and managed 3.5" again....
...but that was because I had access above to mount a Peerless ACC-570 Ceiling Plate.
And it was absolutely necessary because I had to mount the PJ directly over the entry Doors. I wound up with 1.5" to spare !
Smarty, can you shoot an image of the Mount / ceiling? That would help others see what was / how it was done.
