Dropping a cable through ceiling > bottom of wall

Submitted by huongdaoroma t3_100bchk in DIY

Hey guys, I'm thinking of dropping a cable from my ceiling/top of wall to the bottom. Problem is that I have a projector mount already in the ceiling and I need to shift it over a couple of inches to the side to get good image centered with my new projector.

What's the min distance do I have to move my ceiling mount for it to still be stable? The projector + ceiling mount is ~ 10 lb.

Does your projector have a keystone setting? You may be able to center the image without moving the projector.

It has keystone, but looks worse when I use it. After all keystoning lowers the resolution. Making a square out of a trapezoid means you're not using the full resolution. I'd like it to be as straight as possible

You could put a piece of plywood up as a mounting block so you can place it anywhere. If you're picky about how it looks, you can stain/paint it, add some trim, make it round/oval like a medallion, whatever look you prefer.

Bolt the plywood to structure on two or more beams.
