What Is A Monitor? Types Of Monitors Explained

A monitor is an indispensable part of any computer setup, acting as a window into the digital world. Whether it’s for professional work, gaming, or general multimedia consumption, understanding the different types of monitors and their technologies can enhance your user experience.

A standard computer monitor.

A monitor is an output device that displays information in visual form, generated by the computer. It allows users to interact with the computer’s applications and programs through graphical representation. From editing photos to streaming videos, monitors are vital for both creating and consuming content.

Types of Monitors and Their Technologies

Cathode Ray Tube (CRT)


CRT monitors utilize electron guns that fire electrons onto a phosphor-coated screen to display images. These tubes are known for their excellent color and viewing angles.


While they offer high contrast ratios and responsiveness, CRT monitors are bulky and consume more power compared to modern displays. They are still used in some niche applications today.

Liquid Crystal Display (LCD)


Replacing CRTs, LCD monitors use liquid crystals sandwiched between two layers of glass. These crystals adjust to block or allow light through, creating the display image.


TN (Twisted Nematic)

Fast response times and affordable, making them suitable for gaming, though they suffer from narrow viewing angles.

IPS (In-plane Switching)

Offers better color accuracy and wider viewing angles than TN panels, ideal for professional photo and video editing.

LED (Light Emitting Diode)


LED monitors are essentially LCD panels but with LED backlighting, which provides more brightness and color consistency across the screen.


These monitors are energy-efficient, have thinner profiles, and produce less heat compared to older technologies.

OLED (Organic Light Emitting Diode)


OLED monitors feature individual organic pixels that emit light when an electric current passes through, allowing for deeper blacks and a high contrast ratio.


Ideal for high-end users who require superior image quality for detailed graphic work or immersive gaming.

QLED (Quantum Dot LED)


Uses quantum dots to enhance the backlighting of LCD screens, improving the color accuracy and vibrancy of the display.


QLED is popular in high-performance monitors that prioritize color precision and dynamic range.
