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

From the late 1980s till to date, monitor connection types have been evolving trying to keep up with the improvements made in the industry. Everyday manufacturers try to figure a better, efficient and faster 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.

Looking at the steps made to improve pictures relayed we can almost say that we are nearing the actualization of virtual reality which is almost similar to the changes we make in our baths. Some monitor  cables can now transmit 40gb of data per second which make it so much easier to transmit high quality images while maintaining the 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
DVI VGA HDMI
USB-C DisplayPort

VGA Port

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

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

Screen resolution is quite low compared to other monitor connection types since VGA has a maximum resolution of 1900 * 1200 pixels. However, it is important to note it is an improvement compared to its predecessors which had much lower pixels. While using the VGA you will experience degradation in image quality which is primarily caused by the changing of the images from analog form to 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 card because it is rarely supported by many devices currently.

If you find yourself in a situation where you have a VGA port and cable in your computer but your monitor lacks the port you can purchase a converter for VGA to digital signals and it to connect 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.

Despite the fact that VGA is being phased out, it is still used by teachers in schools, seminars, some places of worship and others through the use of projectors which support the cable connection. Older Tv versions allow for the connection as well. It is important to note that for video transmission, VGA transfers video but no sound.

This port may, however, look a little rusty and past its prime.

DVI Port

Digital Visual Interface Port, popularly known as DVI port mainly transmits its videos in digital format 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;

· DVI-A

Transmits only in analog format.

· DVI-D

Transmits in digital mode

· DVI-I

Transmits both in digital and analog format

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

If you need high quality, then with DVI you are home. With their different configurations you will find some offering up to 2560*1600 pixels which is HD video. For monitor sets that support highly defined videos and have a DVI connector port you can easily use 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 but with the newer cable sets there are adapters developed to support the connection to any device.

Currently we have DVI-HDMI cables which 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 in a way that they are bidirectional so you can connect it either way.

DVI to VGA cables are also available so 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 then connect the cables using the adapter.

HDMI

hdmi

HDMI, High-Definition Multimedia Interface, 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. However, when making the choice there is need to consider pros and cons just like gas and mig welding.

People looking forward to transmitting data over long distances without worry of a poorer image then they should consider this as 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 not only quality videos but sound as well. With your cable you can comfortably watch HD videos without loss in quality of pictures or sound.

For home entertainment that needs connection to the television from the computer, HDMI is the best option. Your experience while using it will remain unmatched, high quality videos – fast transmission and original pictures without losing their quality.

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

Usb-C

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

The Usb type C is mainly designed for laptops, MacBooks and mobile phones and has the ability to accomplish tons of work needed 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 you are working on something from your phone. Usb C cables can transfer both sound and videos and at better quality as compared to 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 has capabilities of acting as fast chargers significantly reducing 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 as well.

You can use an adapter to connect to multiple screens if need be. For older models, there are adapters that have been developed for smooth connectivity using type C USb.

DisplayPort

Introduced around 2005, DisplayPort is a high-speed option that enables both video and audio transmission through cables. With the improving technology, currently 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 still remains to be the case with the majority of the high-resolution screens with higher refreshing rate still using the DisplayPort which is designed to support them reliably.

Gamers who use their PCs have been found to prefer display ports over other means 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 a screen for use that will need high quality streaming then check its compatibility to DisplayPort.

Is DisplayPort better than HDMI?

DisplayPort and HDMI complement each other thus it gets quite hard giving a verdict on which one is better than the other. One can be better than the other at one or two features but overall, they serve different purposes and can only be considered in the strengths so as to choose which one to go with. Just like a shower and a bathtub they both serve the same purpose but cannot be compared.

The factors to consider include;

ource

Depending on the video sink available on your source that is only when you can confidently pick one over the other. For instance, assuming your video card only HDMI connectivity is supported, then picking it over the DisplayPort would be prudent.

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

Cable from the manufacturer

Experts advise that using the cables that come boxed with the monitor from the manufacturer have the best performance for that screen as compared to others. When the time for replacing the cable comes it is advisable you 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.

Entertainment

If your screen is for entertainment purposes then 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) which makes 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 on your desk from a single cable. It has been designed in a way that it can easily support an adapter making it way easier to use.

High resolution

In tasks that require higher resolution it is advisable to use DisplayPort since it can support 4 k images. For graphics design and video editing, the display port is still a better choice which gives you clearer images which are easier to work on.
