Monitor connectors that is best for your setup

When setting up your workstation, many people find that when they come to plug everything in, they’re not sure exactly what they’re plugging into what. But your choice of cable can have a huge impact on your experience, especially if you work visually (or are a gamer). This article aims to provide you with a good overview of the most common modern monitor ports and connector types, including HDMI, DisplayPort, DVI, VGA, and USB-C, along with some less common options for those with older or more specialised PC's. So, with no further ado, let's have a a look at all the different types of monitor ports and connectors, and what exactly they are best for.

Rarer Connector Types

Though they are not the most common, let's first have a look at a few older or more specialised cables.

SDI - Enhancing Digital Video Transmission with Serial Digital Interface (SDI)

Serial Digital Interface, commonly known as SDI, is widely in the motion picture industry. It offers a single-pin connection that efficiently transmits digital video signals. One of the major advantages of SDI is the length of cable is supports, up to 300 meters, which makes it great not only for film but for working on monitors placed very far, or even in a different room to the PC. This type of cable is also used in CCTV and video security camera set ups to transfer captured images across short to medium distances.

AV (RCA) - Unlocking the Potential of Analog Audiovisual Signals

AV (RCA) input, although less prevalent in modern times, holds historical significance. It has been a popular choice for connecting video game consoles and other electronic devices to televisions or displays. This connector serves as the gateway for analogue audiovisual signals from electronic devices, which are then converted into AV signals for display output.

NDI - Transforming Audio and Video Projection with Network Device Interface

Network Device Interface uses ethernet networking to smoothly transmit audio and video for projections and transfers. This enables users on the same ethernet network to send and transfer video and audio seamlessly, and has seen many office adopt the tech for presentations and meetings.

Most Common Monitor Connections

The High-Definition Multimedia Interface (HDMI) port is the most widely used connector found on monitors today. Used to connect PC's and laptops to monitors and commonly smart TV's, HDMI supports audio and video signals and offers great sound a video quality, and is supported by most monitors and PCs available.


Initially introduced as an alternative to older USB ports, USB-C can also serve as a substitute for HDMI or DisplayPort. One of the distinct advantages of USB-C over display ports is it's reversibility, allowing users to connect either end to either port and simplifying your setup - especially if you're using more than one screen. And as they're so versatile, you might find the same USB C connector can do more than one job for you. This cable is increasingly found as the standard on newer laptops, smartphones, and tablets.


The Digital Visual Interface (DVI) port is an older connector found on slightly older PCs - though still common enough for us to mention it here today. While it doesn't carry audio, DVI offers a higher frame rate than HDMI for 1080p monitors, and as it transmits digital signals directly without compromising any bandwidth for audio, it produces sharper image quality than many cables. DVI is particularly suitable for gamers who value crisp visuals.

DisplayPort (DP)

New on the scene, DisplayPort is both more versatile and more specialised than HDMI, and may be more appropriate for people who work with video frequesntly. DisplayPort comes in different versions, such as DP 1.2, 1.3, and 1.4, each supporting various resolutions and refresh rates, including 4K and 8K video output.


The Video Graphics Array (VGA) port is an older connection that predates HDMI. While it's becoming less common on newer devices, some legacy devices still feature this port. VGA is primarily display port used to connect older devices that rely on analogue audiovisual signals. It's recognizable by its 15-pin connector with 5 pins in three rows. VGA is not known for delivering the best video quality compared to other connections.

The Significance of Choosing the Right Monitor Cable

Choosing the right monitor cable connector

Making the right choice of monitor cable can significantly impact your overall experience, improving audio quality, resolution, and refresh rate. To help you make an informed decision, the points below explain which cable is best for which use.

HDMI - Simultaneous Audio and Video Convenience

HDMI connectors are ideal for those seeking simultaneous audio and video transmission without the need for additional audio connectors. If you own a Smart TV or a computer with audio and video signal and desire a seamless audiovisual experience, HDMI is your go-to choice.

DisplayPort - Audio and Video Excellence

DisplayPort connectors are sometimes considered the best choice for users who value the highest possible quality audio and video signals. In certain scenarios, DisplayPort cables outperform HDMI on these metrics, but it’s worth checking what will work best for your set up before you dive in.

DVI – Best Refresh Rates

For enthusiasts craving the highest refresh rates at 1080p, DVI connectors are hard to beat. While DVI cables solely carry video signals, they have the advantage of seamlessly integrate with older systems, so if you’re set up’s not the most up to date and you want the best refresh, DVI could be the one for you.

VGA - A Legacy Connection

VGA connectors, although still prevalent, are gradually becoming less common in today's technology landscape. If your monitor provides a VGA port, it can serve as a decent option in the absence of other connectors. However, it is essential to note that a VGA connector may not deliver the same level of video quality as its counterparts.

USB Type-C and Thunderbolt - Versatility in Connectivity

USB Type-C connectors excel in their ability to connect a wide range of devices, from laptops and smartphones to tablets and wireless chargers. Thunderbolt acts as USB-C for Apple device users.

Types of Monitor Cables: Embracing the Blend of New and Old

While new technology consistently surpasses its predecessors, certain other monitor port and connector types remain relevant due to their compatibility with older systems and as a backup option. Despite the dominance of HDMI since its introduction in 2002, older, monitor ports and cables such as DVI, VGA, and AV still find their place in certain monitors and computers, providing a fallback solution in case other connection types are unavailable.

DVI and VGA cables are capable of transmitting video signals, with DVI offering higher precision and velocity, making it a superior choice over VGA. DVI can be easily converted to HDMI, which makes it even more versatile.

In terms of overall performance and capabilities, HDMI and DisplayPort top the pile. HDMI, being the industry standard, offers a superior resolution and the ability to transmit audio signals alongside the video signal, ensuring a complete multimedia experience. DisplayPort, introduced in 2006, boasts even better performance and a higher data transfer rate than HDMI, making it a better choice for users who want the best audiovisual quality. It supports 4K video and can achieve a refresh rate of 144Hz, catering to the demands of both casual users and gaming enthusiasts.
