HI everyone. 1st time poster, longtime reader. I have started my theater build about 2 months ago. I have finished framing and am in the middle of drywall when my wife has changed her mind on how she wants the room. She now wants the screen on the opposite wall.

Here is the issue. There is a steel beam that sits between 8-9 feet from the wall where the screen would go. Removal of beam is not an option. Bottom of the beam (finished and drywalled) is 82 inches from the ground. I was planning on a sony pearl projector with a 110 inch screen. The projector needs to be a minimum of 11 feet from the screen. Will I be able to project the image to the screen past the beam without the beam interfering? And how low will the projector and the screen have to be. I was planning a 1ft riser at starting at 19ft, so the higher the screen and projector the better.

Thanks in advance for all your help. This board is amazing.

You should post this in the Projector Forum, there are many people with this projector that will tell you if this will work, or perhaps other models that will fit this application.

I have a similar issue with a ceiling fan, not sure if it will interfere, I may have to just try it, and abort the fan idea if it interferes.
You can't do that with the beam, but it might yield a low screen...because it may be more line of sight issue, that doesn't matter which projector you use.with or without offsets.

I have my Pearl mounted on the bottom of a soffit covering just such a beam.

You can see it here: (http://caesare.homeip.net:32171/basement/slides/IMG_2123.htm)

The Pearl's lens can be anywhere from right in the center of your screen, to up to 15% of your screen height above the top edge of the screen with lens shift. With a mount to drop the lens below the beam soffit, you have some flexibility to use the lens shift to position your screen.

Then the issue is simply riser height.

Thanks Steve,

That was the type of "plain english" answer I needed. Sometimes it is hard to plan without having the items you are planning for in front of you
By the way, your theater is very nice!

Sure thing, and thanks for the compliment.

Incidentally, while it doesn't have a "lens shift" feature, the throw distance calculator at projectorcetral is often quite useful in the planning stages.
