Ceiling Mounting for Projectors and whether to mount or not mount.


Mounting and Installation



Should you mount your projector? This is always a hard question to answer. It depends. The alternatives to mounting are to put the projector on a shelf (with a lot of room around the projector for ventilation) or put the projector on a table or a chair.

If you need to ceiling mount your projector, there are few things to remember.

Most important: for the power cable, you cannot hide in behind the walls or inside ceiling plywood. This does not comply with housing codes in most States and Provinces. The power cable must always be visible to the naked eye, not hidden within walls or ceilings.

First, you have to determine how far away you will place the projector from the screen. This distance will tell you where to install your ceiling mount.

This requires you to calculate the throw ratio or throw distance.

Without further ado, the throw ratio is determined by a specification such as:

1.2:1 or a range such as 1.2:1 to 1.5:1.

To start, lets begin with a single throw ratio of 1.2:1 or, to make it simpler: 1.2 to 1 . That is what the ":" in between means (to).

A projector with 1.2:1 1.2 to 1 means that for every 12 inches you set the projector away from the screen, you will get a 10 inch picture size.

So, at 12 feet away, the projector will project a 10 feet wide image size.

You have to note that it is the width (left to right) that is 10 feet. It is not the diagonal measurement. With projection screens, they are usually measured in diagonal size (bottom left to top right), so you have to find out what the display width (left to right) is for the screen. Most of the time, screens' technical specifications will tell you.

Now, if the throw ratio of a projector is a range, such as 1.2:1 ranging to 1.5:1, that means the projector has an optical zoom lens. The zoom lens will allow you to change the image size, without moving the projector. The range of image sizes that can be projected, at a set distance is determined by the throw ratios (1.2:1 ranging to 1.5:1).

So, this means, from 12 feet away, the projector can throw an image that ranges from 8 feet (1.5:1 throw ratio to 10 feet wide (1.2:1 throw ratio).




Now, back on the topic of ceiling mounts and Cables:



Second, the video cables you connect from your external devices to the projector will need a pre-determined route to go up to the projector. If you are using the projector in a house setting, many users can install a mount and projector in a few hours.

In some cases, to cut down on visible cords, you can hire an electrician to create or build a power outlet on the ceiling near the projector, so that you can connect power to the projector in a short distance (within 1 feet).

The electrician can also help you determine where to put the cables.

Or, without an electrician, you can buy cable hiders that glue to the outside of your room's ceiling or wall. You can buy these cable hiders from your local home improvement store for about $10 per 6 feet of hider.

The hardware to install a ceiling mount onto the ceiling should already be included with most ceiling mounts. You also have to install the ceiling mount onto ceiling studs. This is important. For more information on how to mount onto ceiling studs, you can google search this topic and there are many YouTube videos that demonstrates this.

After installing the mount onto the ceiling, it should be easy to attach the projector onto the installed ceiling mount.
