How to mount my ceiling mount?

I have the Optoma H31 and I imagine the HD70 is much heavier than the H31. I just built a small 1/2" plywood base that I screwed into drywall anchors in the ceiling (5 of them -- 4 corners, one in center). Then I just screwed my PJ mount into the plywood. It's not going anywhere. Just make sure you use the metal drywall anchors and not the wimpy plastic ones.


You can mount it slightly off center and fix the image with the keystone adjustments. But if you use a method for mounting the PJ like I pointed out (or different but same idea -- not relying directly on a joist/stud) then you can mount it anywhere you want and make sure it's center (don't forget that the lens is offset from the center of your PJ -- I forgot and mounted the base in the wrong location the first time ).

All good ideas...and I appreciate the advice, thanks! The only problem for me is that I can't get above the ceiling to put a piece of plywood between the studs like you did. And while the projector isn't all that heavy, the mount is quite a bit heavier than I expected it to be. I really wouldn't feel comfortable with it just in the drywall with anchors. My joists run horizontal, so I could actually get it pretty straight with the screen, but I can only get two of the screws(bolts?) in the joists and then the corners of the mounting plate I would attach with anchors into the drywall.


So now my only remaining question is what bolts should I use to attach it into the stud? And I'm a complete DIY newbie so what drill bit? or just general instructions on attaching it. Thanks!

This is how my mounting plate looks roughly. I would attach the 2 X's with the bolts in the stud, and then the 4 corner O's with anchors in the drywall.

I put my plywood on the drywall since I already had one layer of drywall in for the ceiling because it's upstairs and code required it to occupy the home (I built the theater later).


Here's a picture of what I mean:



Here's another shot:



One from the back (it's showing the exhaust vent and I haven't finished it off so it's a bit messy but should give you an idea):



I can get a better picture of the mount and board itself if you need it but I think you should be able to get the idea from these. Note that 3 of the sides of the plywood are not painted because a box will go around the PJ to hush it and point the heat to the exhaust vent in the ceiling.

I attached my PJ mount using nuts and bolts to a decorative "plate" that I built using 3 pieces of MDF, then just attached the whole darn thing to one joist in the ceiling with 2 - 3" Zinc coated wood screws. The whole thing weighs probably 25 lbs,,, but 2 - 3" screws will be plenty to hold it up there forever. It's VERY sturdy.

it's actually not just a Canadian thing, but a world-wide thing (save a couple of countries)


accts4mjs, why do you have a vent? Does the PJ give off that much heat that it affects the room, or is this a suspenders and belt approach?

Oh yeah, totally. Without the vent my room goes up about 5 degrees easily. I was just shocked after I put the PJ up and turned it on. It's worse in the summer and not so bad in the winter. I think because we keep the house slightly warmer in the summer and slightly colder in the winter to save money. So the winter slightly colder turns into slightly warmer with the PJ on versus in the summer the slightly warmer turns into sweating like a pig

Yeah, you can get hdmi face plates. Monoprice carries one right here:

You could also just put a plate in that has a bushing that will clean up the hole (I don't have a link for those, but I've seen them). You could also put some wire loom around the cable from the ceiling to the projector that's slightly bigger than the hole and then you'd not only cover it up but have a really cool looking effect with the wire loom (I did that for my ceiling hung surrounds and people comment on how cool the cable looks because it's thick -- eh, who knew that would be cool ).

accts4mjs beat me to it

You guys are great, thanks! I'll see if I can't find a gray one, since that's the color of my outlet plate right now. Now I just have to fix one screw up. The outlet I installed is just slightly crooked. Most people wouldn't be able to tell, but it'll eat me up if I don't fix it lol. I hate to dig more holes in my ceiling but that's part of it I guess
