你需要
一个投影仪支架用来固定在墙上
梯子
比较强力的钻机用来在stud打洞

发帖数: 2005 | 3 If you want to mount on ceiling: the following will work pretty well
1. Peerless PRGUNV Precision Gear Universal Projector Mount (for a 20-30lb
projector, it should work perfectly fine).
2. Peepless extension column (EXT 006, for example, or other length, you
have to decide based on ceiling height, how high you want to mount your
projector).
You don't need to buy 1 & 2 if your projector need to stay close to ceiling
height.
3. Peerless Ceiling Plate (Cmj 490, for ceiling joist with 24" intervals, or
other model for jost with other distance).
1, 2 & 3 are what I used. If you are going to mount your projector directly
against ceiling, you will mount item 3 directly to a single joist, this is
what its instruction manual says. This is not very good, in my personal
opinion. In that case, I would prefer attaching 3 to thick plywood using
strong bolts/nuts/washer and attach the plywood to two joists.
Not hard to do. Key thing is you have to find accurate ceiling joist
position, and make sure you use lag bolt that is strong and long enough.
To make sure you find the center of the joist, you can do the following:
1. Try to find joist using stud finder.
2. Confirm and find the edge of the joist by drilling using very thin drill
bit. Drill small holes to test where the edge is, and then you will be sure
to know where the center is. Do not just blindly trust stud finder.

发帖数: 2005 | 5 Use fixed screen if you can. It is better than pull up/down screen. Fixed
screen doesn't need that, unless you want the kind of fixed screen that has
masks so that you can have different screen aspect ratio (like 2.35:1 and 16
:9)
