Less obvious tips for PJ hanging?

Now that the drywall is primed in the basement, I am starting the finishwork. Before I get too much farther, I want to nail down the exact location of the PJ. I am looking at the Panny 3000U. While I am looking to keep it towards the wide angle side of its throw range, there is still room on either side of the range to make adjustments front to back.

Are there any nuggets of logic out there that people would like to share about their placement that wouldn't seem obvious? (not including standard things like keep the PJ level and square to the screen, distance needed to fill the screen, etc.) Please share the unique conclusions that you have come to which a distance chart on Projectorcentral would not convey to the average first-timer.

Is it better to have the PJ mounted in front of/directly overhead/behind the main chair? Why?

Anyone find that their PJ is close to getting bumped by people on the riser when they get up out of their chairs? Etc.

Thanks!

Not an issue. The basement will have drop ceiling tiles.


Again, ceiling tile makes this less of an issue to change down the road. Further I was planning to just use the wall for the first bit to make sure we are happy with the screen size.

A 120” 2.40:1 screen at the widest setting puts it at 12 ½ feet. The head position of the first row will be at 11 feet. This puts the back of the PJ at somewhere around 13 to 14 feet which is right where the “aisle” space of the second row/riser is. The riser is approx 12” high with 8 foot ceilings in the room (after the drop ceiling.)

Anyone have problems with people bumping their PJs while getting to/from their seats on the riser? That is my main concern right now.

Thanks for the input.

Yes please.

How far back do you have the PJ? And how far down from the ceiling do you have it?

If I put it such that the lens is physically no higher than the top of the screen (I understand this is a requirement to use the pseudo-anamorphic shift capabilities), that puts it at about 2 feet down from the ceiling and right in the prime area for people to bump it. Any suggestions short of building a cattle guard around it?
