7 tips to install the projector in your house

 

Installation a projector at home, office or in a classroom is definitely different from configuring a TV, but in most cases, is still quite simple, if you know the steps. Here are some tips to keep in mind, related to the acquisition, location and interaction between the different components of a projection device.

Nowadays, the projection and the devices that serve it enjoy an increasing use, being more and more accessible. But for all technical specifications to work in optimal parameters, you need to consider a few things even before buying the devices. Which are these?

What it means to use a video projector

The operating principle of the device is the distribution, the design of the computer content on any smooth and clear surface (screen, wall, etc.). If you want to use such a system in school, it is preferable to project it on a whiteboard, so you can write down what appears on it.

A video projection device consists of a dedicated computer, a video projector, a white screen and adapted sound equipment. The dedicated computer is recommended to have internet access.

Projection screen or white wall?

On what medium do you intend to project the image? If a white wall can do the job very well, provided it is perfectly smooth, there are paints that will improve the result, if needed. But a screen dedicated to this use is still the best solution to keep the colors and brightness.

Fixed to a frame or tripod, or that can be rolled or even incorporated, its size depends on the camera, distance and video projector. One of the technical features of screens is their ability to optimize the contrast and brightness of the image. If a ratio of 1 to 1.1 is sufficient for high-performance models, it would be better to choose one with a gain of 2.1 for low-brightness video projectors.

What is an interactive projection

Interactivity allows you to control the computer in the projected image: the stylus or finger replace the mouse. By transforming the projected image into a giant “tablet”, interactivity naturally integrates ICT into a learning session. Thus, students become familiar every day in the IT environment, using a word processor, or searching the Internet.

How and where to place the projector relative to the screen

The questions are so important that it’s worth asking yourself before you buy the device. Where do you plan to install the projector and how far will it be from the wall or screen? Because the ideal is to install your equipment in front of the projection surface.

Unless you choose a model with a “lens change” that allows you to keep the image undistorted, most devices require a minimum distance of 3 m to get a 2.50 m diagonal image.

By dividing the distance between the wall and your device by the width of the image you are considering, you will get the ideal projection ratio that the video projector should have. And if the distance is not enough, you can always choose a projector with ultra-short projection distance, which can be installed at 50 cm from the screen.

Where to install the video projector

The first thing you need to do, even before considering purchasing a video projector, is to determine if you are going to project on a screen or on a wall. If you project on a screen, you should also buy the screen with the projector.

Most video projectors can transmit images to a front or rear screen, as well as from a table or ceiling platform.

To be placed behind the screen, you need a screen compatible with the rear projection. If the projector is mounted in this position, it means that the image will be inverted horizontally.

However, if the projector is compatible with this system time, it will provide a feature that will allow you to perform a horizontal reversal of 180 degrees so that the image has the correct orientation to both the left and right of the area. view.

Ceiling installation

To project from the ceiling (either front or back), the projector must be placed upside down and attached to a ceiling mount. This means that the image, if not corrected, will also be upside down. However, ceiling-mounted compatible projectors include a feature that allows you to flip the image so that the image is projected upside down.

Also, for ceiling installations – before drilling holes in the ceiling and screwing the mount, you need to determine the desired distance from the projector to the screen.

Obviously, it is very difficult and totally useless to climb a ladder and hold the projector upside down to find the right place. Remember, the required distance from the screen is the same as on the floor. So, the best thing to do is to initially install the video projector on a table or floor, which will meet the correct distance between the screen and the transmitter you want and then use a ladder to mark the same place / distance on the ceiling.

If you intend to install a video projector on the ceiling it is better to consult a specialized installer, to ensure that not only the distance between the devices, the angle to the screen and the ceiling mounting is done correctly, but also if the ceiling will support both the weight of the projector. , as well as the fastening system.

How to calculate the distance from the screen

Another tool that can help the location of the video projector are the distance graphics provided in the device user manual and the distance computers that projector manufacturers provide online. Two examples of online remote computers are published by Epson and BenQ.

The distance between the projector lens and the variousprojection screens , the zoom setting and the video format affect each size of the projected image. Refer to the specific instructions in the user manual to determine the appropriate position for the projector.
