Graphics or Video Cards    

These are the elements that control the images displayed on the screen.

Graphics or Video Cards

They usually do hardware acceleration, where they contain chips that allow the signal to be processed and, at the same time, interpreted to create textures, effects, and other effects displayed on the screen.

Plastic Covers 

Monitor plastic Cover

A plastic cover is an outer cover that protects the internal circuits and shields them against external effects.


Support is a part of the monitor that allows the screen to move from one position to another. The monitor, when tilted back, supports it.


While working on the monitor, its position on the monitor is also important. That’s why the monitor stand is also an important part of the monitor.

The monitor stands are made of different materials. But most of the stands are made of plastic.

Connector and Data Cable

Desktop computers today have different types of connectivity, such as HDMI, Display Port, and VGA. All of these connectivity types have different functions and use cases.

A monitor may require some older-style connectivity and cables in addition to the latest, fastest connectivity. Below is a detailed description of a monitor’s various connectivity and data cables.

Power Connector

A monitor’s power connector is the cable that carries electrical power.


With USB-C, you can do much more. You can set up your monitor via USB-C. Not only are you getting a monitor port, but you can also use USB-A to connect your external drives or other peripherals.

You can connect multiple gadgets to your monitor using the USB-C port, which is especially handy when connecting your smartphone, tablet, and laptop to your monitor.


VGA is an old-fashioned type of connector. It provides an analogue feed with a maximum resolution of 1900 x 1200 pixels.

Nowadays, these connectors are being gradually replaced by their digital counterparts.


The quality of the HDMI cable is quite important. HDMI (High-Definition Multimedia Interface) ports are the most popular in the market.

Film companies such as Universal, Warner Bros., and Disney use HDMI (High-Definition Multimedia Interface) to display their films, as well as technology and video game manufacturers such as Panasonic, Philips, Silicon Image, Sony, and Toshiba companies also use HDMI technology.

There are 4 types of cables available: HDMI, HDMI 2.0, HDMI 2.0 with ethernet, and HDMI 2.0 with audio.


DVI is a video display interface. It was developed as an industry standard for transmitting digital video content for display devices such as monitors at 2560 x 1600 resolution.

Most monitors today use a DVI connection. DVI connectors support DVI-A (analog only), DVI-D (digital only), or DVI-I (both digital and analog) signals.

Here are details about- Function of the monitor in the computer.


DisplayPort is a newer connection introduced in 2008. Most displays still use the VGA connection, but in recent years, DisplayPort has become more popular, and both connections are now found on different types of devices.

DisplayPort is usually reserved for high-end graphics cards and can be used for gaming and video editing.

DisplayPort cables are divided into three types: DisplayPort 1.2, DisplayPort 1.3, and DisplayPort 1.4. With these cables, you can transfer data between devices, such as computers and monitors.

The newest DisplayPort 1.4 cables are also ideal for gamers thanks to their ability to transfer 8K video rates of 60 Hz refresh rate and HDR video.


Bluetooth is a wireless technology that allows data to be exchanged and displayed on the monitor. It operates short distances to keep the monitor connected to other devices.


“Anode” is a type of part of the monitor. This anode works to transmit electrical energy to the screen through the wire.

Main Card

The main card is the most important part of the monitor. This part contains the elements that make the monitor run, such as the processor, RAM, and graphics.

Interface Board     

The interaction board or platform is an integral part of the monitor. The board provides control and monitoring of the monitor’s operations.

Amplifier Circuit

Convergence Ring 

The convergence ring serves that where the electrons are stored and controlled, so the phosphor layer of the display screen is impacted and provides a certain color.

Bending Coil

A bending coil moves an electron beam at the correct point on a screen.

Horizontal Outlet

Horizontal deflection is a monitor portion where the horizontal coil is fed from the deflection yoke.

Electronic Cannon

Electronic cannon is included as a part of a monitor trying to create a very fine electron beam that impacts the screen, passing through all the electrodes it possesses.

Focus Grid

Focus grids are responsible for keeping the electrons in their position when they collide with the screen or anode in a computer monitor.

Screen Grid

This is where electrons have greater power than the cathode. Thus they attract each other.
