Is a Projector an Input or Output Devices | Types, Advantages & Uses


A couple of days before one of my subscriber asked me is a projector an input or output devices in the computer system. Therefore I thought to write a detailed post related to the topic.

Let get started

Introduction To Projector
Yes, the projector is an output device in computer.

The projector is an output device of a computer that is used to display images on the large screen generated by a computer system.

The generated outputs can be displayed on white screens, walls, or on a clean surface where the outputs can be clearly viewed.

The projector plays a vital role when displaying certain information like presentations, videos, etc. to a wide audience just like television and computer monitors.

What is a Projector?

The projector is an output device that is made of a series of dots, chips, lenses, and colour wheels.

The projector is capable of displaying moving objects, images and videos on various other sources like walls, cloths sheets, etc.

There is a lot of confusion around whether a projector is an input or output device but here in this post we will have a clearer understanding of projectors its types, uses and advantages with pictures and examples.

The projectors are used in the educational sector where teachers and instructors teach students on a large screen to cover the entire class for better reach and clarity.

They are also used in displaying presentations for a group of audience for proper visibility and understanding.

The projectors are also extensively used as a home theatre for watching movies.

In simple words the projector is an electronic device that is more than capable of displaying videos, moving images and presentations on the wall or on clearer surfaces.

They are used in the majority of the companies where the need of training and planning is extensively required for a group of individuals sited in big rooms or auditoriums.

The projectors are handy when the instructor or trainer or teacher has to involve their audience in the presentation to make them proactive and aware.

They can be connected to a computer system with the help of HDMI {High Definition Multimedia Interface} cables, Bluetooth, WI-Fi, or old fashioned VGA {Video graphic Array} ports.

The projectors are available in various different sizes, shapes, prices and functionality.

Is a Projector an Input or Output Devices Computers?

Yes, the projector is an input device.

Before going further, to understand the topic more easily we must be aware of what is an input and output device so that we can get a clearer picture.

Now let’s talk about input devices of computer system

The input devices of a computer system are devices that take or accepts raw data and information from outside the world and later transfer it to the system for further processing and handling.

The primary functions of the input devices are to present the data, instructions and information to the CPU {Central Processing Unit}.

Some of the examples of input devices are
  • Keyboard
  • Mouse
  • Joystick

Let us understand output devices.

The output devices are electromagnetic device that receives input from the computer system and generate an output on paper.

Which are also called “Hard Copy”.

The output devices are extensively used for printing and producing outputs on papers, sheets, etc.

Some of the examples of output devices are as follows.
  • Printers
  • Projectors
  • Monitors

As per our above discussion, we can jump to a conclusion that projectors falls in the category of output devices that are responsible to generate output on walls and thin clearer cloths.
