Monitor connection types & display ports: dvi, vga, hdmi

From the late 1980s till today, monitor connection types have been evolving. They’ve been trying to keep up with the improvements made in the industry. Every day manufacturers try to figure out a better, more efficient way to relay the images and videos and improve user experience. While shopping for a monitor cable, we need to be as vigilant as a person looking for gauge wires or circuit breakers.

Look at the steps made to improve pictures relayed. We can almost say that we are nearing the actualization of virtual reality. Some monitor cables can now transmit 40GB of data per second. It makes it so much easier to transmit high-quality images while maintaining quality.

Getting the right type can be likened to choosing the perfect welding glasses for your task or extension cord to power your devices.

Types we’ll be going through

VGA Port

Being one of the oldest types, VGA is highly popular and the most used. Video Graphics Array was first used in 1987 and has been used since then. Like best lawn garden tractors, their ports last for a long time.


It consists of 15 pins divided equally into 3 rows consisting of 5 pins that transmit only analog data. Each pin has a different function, transmitting colors for smoother and better viewing.

The screen resolution is quite low compared to other monitor connection types. It’s because VGA has a maximum resolution of 1900 * 1200 pixels. However, it is important to note it is an improvement compared to its predecessors. They had much lower pixels! While using the VGA, you will experience degradation in image quality. It is primarily caused by changing the images from analog form to a digital form viewable by screens in the market today.

The technology is slowly becoming obsolete with many new screens in the market lacking a port for the connection. Additionally, some computer manufacturers have removed the port from their video cards. Many current devices rarely support them.

You may find yourself in a situation where you have a VGA port and cable in your computer, but your monitor lacks the port. What do you do? You can purchase a converter for VGA to digital signals and connect it to the screen. In the same way, we have SAE to metric conversion charts. We have adapter recommendation tables from manufacturers we could look at.

Even though VGA is being phased out, teachers still use it in schools and seminars. Some places of worship will also have them, and others through projectors that support the cable connection. Older TV versions allow for the connection as well. It is important to note that VGA transfers to video, but there is no sound for video transmission.

However, this port may look a little rusty and past its prime.

DVI Port

Digital Visual Interface Port, popularly known as DVI port. It mainly transmits its videos digitally from the source (computer) to the endpoint, usually a screen or projector. Unlike most ‘transmission types which rarely have different subtypes, it has three types;


It transmits only in analog format.


It transmits in digital mode.


It transmits both in digital and analog format.

This type mainly supports the transfer of video data without audio. However, some cables will transfer both but rarely find them in the market. With DVI, you will need a second sound output to better view if you watch a video.

If you need high quality, you’ll strike gold with DVI. With their different configurations, you will find some offering up to 2560*1600 pixels which are HD video. There are monitor sets that support highly defined videos and have a DVI connector port. You can easily use it for improved viewing.

Devices with the DVI display ports are mostly computer monitors and projectors. Some television sets have the supporting ports for the DVI connection, but rarely will you find it. With the newer cable sets, there are adapters developed to support the connection to any device.

We have DVI-HDMI cables that were developed to support connection to output and input sources with either connection but not both. It is not uncommon to find computers with only DVI ports in the video card and screens with HDMI in the display ports or vice versa. The cables are designed so that they are bidirectional to connect them either way.

DVI to VGA cables are also available. You don’t have to change your older monitor to accommodate the newer requirements. With a VGA screen, you will buy an adapter to convert from DVI to VGA and connect the cables.



HDMI stands for High-Definition Multimedia Interface. It is known for high-quality video transmission among various media. Whenever you are looking for a mode of video or picture transmission and HDMI is among the choices, then look no further. When making a choice, there is a need to consider the pros and cons.

People looking forward to transmitting data over long distances without worrying about a poorer image should consider this an option. HDMI cables are reliable over long distances that exceed 20 meters and occasionally reach 30 meters.

Unlike the earlier discussed types, HDMI can transmit quality videos and sound. With your cable, you can comfortably watch HD videos without loss in quality of pictures or sound.

HDMI is the best option for home entertainment that needs a connection to the television from the computer. Your experience using it will remain unmatched. It can transmit high-quality videos with fast transmission and original pictures without losing their quality.

HDMI can also be used for office work and presentations as well. For instance, their high-quality images can be utilized for presentation through a projector for clearer images. Connections to screens from the CPUs through the video ports via HDMIs are gaining popularity among people. Newer computer models have started ditching older types like VGA for HDMI.



Developed by major IT companies, it stands for Universal Serial Bus Type C. The main purpose was to act as the sole cable connection between a monitor and a computer.

The USB Type-C is mainly designed for laptops and mobile phones and can accomplish tons of work needed to be done. For instance, it can charge a laptop while transferring data from one source to another.

It is bidirectional and can be used in laptops to project phone screens while working on something from your phone. USB-C cables can transfer both sound and videos at better quality than the earlier mentioned types.

USB-C has high transfer speeds that can get up to 40 GB/S giving you the ability to stream 4k over it. More research is being done to 100% reliance on USB-C for monitor connection types.

As a laptop or phone charging device, it can act as a fast charger. It significantly reduces the time spent charging your device. It can handle up to 100 W of power while charging, making it a perfect fit for laptop charging.

You can use an adapter to connect to multiple screens if need be. Some adapters have been developed for smooth connectivity using type C USB for older models.

Introduced around 2005, DisplayPort is a high-speed option that enables video and audio transmission through cables. With the improving technology, it can stream ultra-HD and 4k seamlessly.

When it was first introduced, display ports were mainly compatible with high-end monitors and graphics cards. This remains the case with most high-resolution screens with higher refreshing rates still using the DisplayPort. It’s to support them reliably.

Gamers who use their PCs have been found to prefer display ports over other means. It’s due to their high resolution and transfer rates without losing image quality. Graphics designers use this mode as well due to their high-quality images. When choosing a computer or screen that will need high-quality streaming, check its compatibility with DisplayPort.

Is DisplayPort better than HDMI?

DisplayPort and HDMI complement each other. It gets quite hard to decide which one is better than the other. One can be better than the other at one or two features. Overall, they serve different purposes and can only be considered in their strengths to choosing which one to go with. Like a shower and a bathtub, they both serve the same purpose but cannot be compared.

The factors to consider include;


Depending on the video sink available on your source, that is only when you can confidently pick one over the other. If your video card only has HDMI connectivity supported, it would be prudent to pick it over the DisplayPort.

You might argue that you can use an adapter to enable the connectivity. The quality might not be as good as the originally intended cable.

Cable from the manufacturer

Experts advise you on the cables that come boxed with the monitor from the manufacturer. They have the best performance for that screen compared to others. When replacing the cable comes, you should check the user manual for the prescribed model. Using the manufacturer-advised cable ensures that you have a properly functioning device that will hardly disturb you.


If your screen is for entertainment purposes, you wouldn’t need to choose a display port over the HDMI. HDMI has been improved over time to give the best experience needed while relaxing at home. HDMI supports Audio Return Channel (ARC), making it possible for you to connect the audio to your soundbar from the TV.

Multiple connections

For users that need to project their work to multiple screens, then they should acquire display ports. You can easily set up 3 to 4 screens from a single cable on your desk. It has been designed to easily support an adapter, making it way easier to use.

High resolution

It is advisable to use DisplayPort in higher resolution tasks since it can support 4 k images. The display port is still a better choice for graphics design and video editing. It gives you clearer images that are easier to work on.


What type of connection is best for monitors?

If you are looking for the correct type of connection for your monitor, then HDMI is the perfect choice for your needs.

The abbreviation for this type of connection comes from the name “high-definition multimedia interface.”
HDMI is the ideal choice for use with any TV or PC monitor.

Of all the types of audio-video connections, HDMI is the most popular option.
Most often, it is used with:
– TVs
– tablets
– notebooks
– game consoles
The feature that makes this type of connection a top choice is that it can transmit:
uncompressed video
uncompressed audio
Due to this unique feature, this type of connection is present in most multimedia devices’ structures.

What are the different ports for a monitor?

Most monitors have the following types of ports in their structure:
– DisplayPort (DP)
– USB Type-C

HDMI can transmit both audio and video signals.

This type of connection is an ideal choice for TVs and PC monitors.
DVI can only transmit video signals.

This type of connection is suitable for older systems or transmitting a 144 Hz frequency at 1080p.
DisplayPort can transmit both video and audio signals.

If you are looking for a connection that transmits at a frequency of 144 Hz and 4K quality, this is the right choice for you.
VGA is an ancient type of connection.

Is DisplayPort better than HDMI?

Depending on the type of monitor you want to use, DisplayPort may be a better option for your needs.
If you want to use a TV, HDMI may be a better choice in this case than DisplayPort.

HDMI can transmit both video and audio signals via a single cable.
And if you want to use a PC monitor, then DisplayPort is a better choice.

Although DisplayPort may be very similar to HDMI, it is most commonly used with PC monitors.
DisplayPort is also capable of transmitting very high-quality video and audio signals.

What kind of cables are used to connect the monitor?

There are four types of cables with which you can connect a monitor:
– DisplayPort

Some types of monitors can support more than one type of cable.
In this case, you should choose only one type of cable that you want to use and connect only this one to the monitor.

VGA cable is also often called:
– D-sub cable
– analog video cable

You need to connect one end to the monitor you will use for this type of cable.
This can be a TV or a PC monitor.

And you need to connect the other end of the cable to the VGA port in the computer.
For the DVI cable type, connect one end to the computer monitor and the other end to the specific port in the computer structure.
This type of cable can only transmit video signals.

That is why it is recommended to use it only on the monitor of a PC.
You can use HDMI for both a PC monitor and a TV.

Take one end of this cable and connect it to the type of monitor you want to use.
It would be best to connect the other end of the cable to the port in the computer.

What’s the difference between a DisplayPort and HDMI?

The differences between DisplayPort and HDMI can be easily placed in a list.
First of all, we need to talk about the bandwidth provided by these types of connections.

DisplayPort is capable of delivering more bandwidth than HDMI.
But what are the advantages of this higher bandwidth? You might be wondering.

A higher bandwidth allows the cable to transmit multiple audio and video signals simultaneously.
This advantage can be helpful if you want to connect multiple monitors to the same computer.

Due to this feature, gamers often use DisplayPort with their computer monitors.
On the other hand, an HDMI cable offers the option of an Audio Return Channel (ARC).

This option can be helpful if you want to connect a TV to a home cinema set.
Thanks to ARC, the sound will be taken from the TV and transmitted to the home cinema set.

And from here, it will emit the sound through the speakers around you.
Due to this feature, an HDMI cable is preferred with a TV.
