Different Types of Monitor Cables | Computer Monitor Cable Types: What & How They Work?

Monitor Cables

With so many types of cables around one might find it hard to find differences among them all. Mentioned below are the most common computer cable types one can find while dealing with computers.

1. VGA Cable

It is also known as D-sub cable, analog video cable

It gets it one end connected to computer monitor, television (PC input port) & Connects its other end to VGA port on the computer

2. DVI Cable

It Connects its one end to: computer monitor & gets it other end connected to: DVI port on the computer

Furthermore, there are 2 kinds of DVIs & that are as follows:

  • DVI-I
  • 2) DVI-D.
    In order to get an insight about its type one must keep this thing in mind very clearly that DVI-D does not have the extra pins around the long pin but DV-I does contain extra pins around itself , DVI-D is also having a pure digital signal over DVI-I.

3. HDMI Cable

It connects its one end to computer monitor, television & gets its other end connected to HDMI port on the computer.

Note: If you want to use your computer as a television purpose then it is highly recommended that you use an HDMI cable as your PC cable connection since it is able to conduct both display and sound – So by this one can not only use its TV displays as a monitor but also make the best use of your TV speakers to play PC audio respectively.

4. PS/2 Cable

It gets itself one end connected to PS/2 keyboard or PS/2 mouse & gets it other end connected to PS/2 ports on the computer

  • Purple PS/2 port: keyboard
  • Green PS/2 port: mouse

5. Ethernet Cable

It is also known as RJ-45 cable

As clear from the name it gets it one end connected to the router, network switch

& other end connected to Ethernet port on the computer

6. Audio Cable

It is also known as a phone connector (since 3.5mm cards are often found on mobile phones too)

It gets it one end Connected to computer speakers primarily with the ranges of 3.5mm headphones, 3.5mm microphone respectively

 & gets it other end connected to audio ports on the computer. For instance Green audio port: computer speakers or headphones

  • Pink audio port: microphone
  • Blue audio port: MP3 player, CD player, DVD player, turntable, electric guitar etc (line-in port to play &  record sounds from the above mentioned devices)

7. USB Cable

For USB computer cable connections, there are two popular formats either its of USB 2.0 and the newer format is of USB 3.0

How to differentiate & let others know about USB 2.0 and 3.0 cables separately: USB 3.0 cables have a blue tip, and sometimes you can find a SS “Super Speed” printed label on it. 

Since USB was proposed to be the one computer cable connection to substitute them all, it’s no wonder that the likely benefits for a USB port are quite incredible. For this computer cable instruction guide, are as mentioned below:

Connect its one end to: USB device

  • Storage devices: USB flash drive, external hard drive, external optical drive
  • Input devices: USB keyboard (wired and wireless), USB mouse (wired and wireless), webcam, scanner, gamepad
  • Output devices: printer, all-in-one office machine, USB speaker
  • Wireless adapters: network (Wi-Fi) adapter, bluetooth adapter, 3G adapter
  • Data (and charging) cable for mobile devices such as mobile phone, tablet, MP3 player

Connect other ends to USB ports on the computer

8. Kettle Plug

One needs to get its one end connected to AC power socket & the other end connected to a power supply component i.e., computer monitor


One of the high-speed cables among the most as seen in laptops and are proficient enough of carrying Data, video and other useful information.

There are 2 current kinds of Thunderbolt, the older version Thunderbolt 2 is can also be jumbled up with Mini Display ports as they look identical

The Mini Display Port (right) will only carry Video.

And Thunderbolt 3 is also considered to be a USB-C on Apple Macs.

10. Display Port

Display Port works the best if all you need is a fast, high-resolution image.
The cable has enhanced quality over HDMI and is the improved viable option if you have this user interface.

What are the Most Popular Computer Monitor Cable Types?

Original VGA connectors

One of the previous & initial monitor cables present, VGA (Video Graphics Array) it is common monitor and some of the primary prototypes of LCD monitors.

You can identify these video cables by the 15 small holes present on one end of the finish line of the cable, and 15 pins will be present on the other.

DVI cables

At first look, the DVI (Digital Visual Interface) cables look relatively a bit kind of VGA but they don’t  base some of the pictorial noise that the lesser quality VGA cables can create. DVI has relatively more pins, with up to 24 pins on the end for digital video signals boosting purposes, plus four more pins present for analog.

The popular HDMI

If you’ve ever bent down towards a newer television, you’re perhaps already mindful of the compatibility that HDMI (High-Definition Multimedia Interface) has with almost every video module in the modern era of the entertainment systems.

HDMI is considered as a digital standard because it is famous and cost-effective. This same cable brings up sound information, too, so it can double as an audio connection for displays with internal speakers. Each end of the HDMI monitor cord kind contains 19 pins, but is of a very small size than either VGA or DVI.

There are currently three types of HDMI that consumers grabbing it today, all organized with 19 pins in a different order.

Type A is the largest and the most frequently used for televisions, monitors, and 4K screens. Type C is a bit smaller (often named as a “mini”) and is the most famous choice for portable devices. Type D is the smallest among them and is also known as a “micro HDMI.” Types B and E are not currently used for consumer products.

DisplayPort™ and Mini DisplayPort™ technology

If you use any Apple® products, you will likely need DisplayPort™ or Mini DisplayPort™ cables. These are usually compatible with most Mac® devices and have the same video quality as HDMI or DVI.

They are also used with a variety of other brands of computing devices, though it may not be the only port on the device.

If you find yourself needing to connect an incompatible monitor into a DisplayPort™ device, you can purchase an adapter to connect into the 20-pin interface.

USB options

Some monitors are comfortable & have good compatibility with standard USB (Universal Serial Bus) connectors. Rather than other types of monitor cables. It is effective yet cost-effective.

Common, but old.

Use of Monitor with the connectivity of VGA port.

The most promising  IBM computer manufacturer industrialized its very first connection standard, used nowadays too, in 1987 for its PS / 2 series PCs. The blue triple-action interface worked accurately with old CRT displays, one needs to thank its requirement that is analog nature. But then flat LCD digital screens come up in the market, resolutions began to cultivate faster, and the VGA port started to give up its breed in the market. Today, it is more seldom compiled, but up till now, an arrangement of devices such as home players, projectors, TVs, etc. are still prepared with VGA ports. Perhaps, for most often in many from now, it will remain not as needed or desired, but still the global standard.

Use of Monitor with  the connectivity of DVI port.

This abbreviation stands for or you can say it is known to be as Digital Visual Interface. It transfers a video signal in digital format while sustaining high image quality or maintains high resolution. In the mid of 2000s, DVI was interchanged with the rapidly old-fashioned school VGA. The capacity or aptitude to transfer both analog and digital signals, provisioned for large (in that time as mentioned above ) resolutions and high frequencies, and the lack of low-cost competitors led to DVI becoming a customary port for today. Low-cost video cards are equipped with the Single Link DVI. The maximum resolution, in this case, is 1920×1080 pixels – Full HD. More expensive video card models have a Dual Link DVI interface. They can be interlinked to monitors with a resolution of up to 2560×1600 pixels.

Modern types.

Monitor with HDMI port – the monarch of multimedia

HDMI is an abbreviation of  High Definition Multimedia Interface. In living era homes are equipped with entertainment devices, such as flat-panel TVs and Blu-ray players, HDMI is the universal connection interface. As previously was the case of DVI, the signal is communicated in digital arrangement, which means sustaining the original standard quality. Jointly with HDMI, HDCP (High Bandwidth Digital Content Protection) tools & equipment were matured to put a stop to the piracy and illegal copying of video materials. The first devices with HDMI support that looked up in late 2003. Since then, the standard has been altered many times; in specific, the provision of new audio and video formats has been included in it

. specifically, why did HDMI become so famous?
• Length of cabling up to 25-30 meters;
• Sound broadcast (even multi-channel) jointly with video – no separate speakers were required;
•Appropriate small connectors;
• Provision for varied devices: players, TVs, projectors, DVRs, game consoles, etc.;
• Very high resolutions;
• 3D-picture; possible together with ultra-high resolutions (versions of HDMI 4b and 2.0).

The projection for HDMI is the most everlasting – elaborations that keep us moving. In 2013, the specifications of version 2.0 were carried out; this standard is well-matched with old wire connectors, but it backs up resolutions that are more striking & remarkable and other excellent features.

Use of Monitor with Display Port – only becomes ever present .

For many years, computers were seldom equipped with this competitor of HDMI this despite of the statistic that DisplayPort has many advantages of using it:
• Backing up for very high resolutions next to with stereo signal;
• Audio transmission;
• Extraordinary length of cabling

This interface technology is even more lucrative for manufacturers than the approved certified HDMI: they don’t require to pay the wage to the developers the 15-25 cents that would be essential for users of HDMI. Although in its preliminary years of existence this kind of connector was not mainly famous, now computers are more frequently made with a pair of Display Ports.

Use Of Monitors with USB Port

The link with the assistance of a USB connector became viable when version 3.0pops up in your displays. By Using the DisplayLink adapter, you can get your monitors connected with a DVI / HDMI connector to the USB port of your laptop or computer. Such ports are the basic customary for connecting external devices, which all manufacturers of these devices are fevering for it. USB ports can connect mice, keyboards, printers, scanners, modems, card readers, flash drives, cameras, cell phones, players, hard drives, optical drives, etc & the list goes on n on. This connector is required for those who make a strategy to work concurrently with multiple monitors & devices respetively.
