Projectors create an unfavourable environment

For projectors to project a bigger, sharper, and brighter image, it has to be installed and used in a favorable environment.

The dark or 100% light-controlled room is a favorable environment for the projectors.

Movies can be watched in a dorm room, however, for a classroom, it might not be a favorable environment.

The students would not be able to read or take notes. All they can do is ask questions while staring at a big bright screen.

Installing projectors in each classroom would be expensive

Projectors are not only expensive to get, they are just as expensive to maintain as well.

First, you would burn a hole in the pocket and get one projector for each room, and then installation and maintenance costs would be any other plus.

The projectors would noticeably increase the electricity charges

It is believed that an HDTV consumes a lot of electricity. The projector’s case is a bit more serious, the said electronic device even consumes more electricity than the HDTV.

Therefore, having a projector in each classroom would noticeably increase the electricity charges.

get involved in malicious activities

To give a lecture on a projector the lights of the classroom have to be turned off. The non-serious students would take it as an opportunity to get involved in malicious activities.

They would not be able to concentrate on the lecture and will keep disturbing the other students as well.

The projector would take most of the space

Even if the projector is small in size still, a little amount of space would be required to install the projector and the screen.

To sprinkle salt to the wounds, you might have to add external speakers as well. Even if you bring a Bluetooth speaker to connect, there would still be a mess.

There would be a lot of noise

Most projectors are noisy. Even if we take steps to make the projector quiet, they would still produce noise. Therefore, if the classroom is noisy how would students be able to hear the professor. Moreover, it would give the students and the teacher a headache.

Summary

Installing projectors in the classroom can be a good and a bad idea. It would be a good idea because it helps in focusing and learning better.

However, if we try to judge the other side of the picture, the projector would create an unfavorable environment for the classroom, increase electricity charges, give non-serious students a favorable environment to be involved in malicious activities, require a lot of space and capital to be bought, installed, repaired, and maintained.
