Introduction to the Types of Monitor Cables

When you set up a monitor, you usually pick from different types of monitor cables. The most common types are:

• HDMI

• DisplayPort

• VGA

• DVI

• USB-C

You can find VGA cables in many schools and offices with old computers. DVI cables are good when you do not need high resolution. USB-C cables are popular now because they send video and power for new devices. These types of monitor cables have changed as time passed, making it easier to connect your screen. If you know the differences between these types of monitor cables, you can choose the best one for your setup.

Key Takeaways

• HDMI cables are used most for monitors and TVs. They send both high-quality video and sound in one cable.

• DisplayPort is best for gaming and fast computers. It gives higher refresh rates and can link many monitors together.

• DVI cables give a clear digital picture but no sound. You will see them mostly with older monitors.

• VGA cables are old and use analog signals. This can make the picture look worse. Only use VGA if you have no other choice.

• USB-C and Thunderbolt cables are the newest types. They send video, sound, data, and power at the same time. This makes them very useful.

Types of Monitor Cables

When you check out the types of monitor cables, you can see how technology has changed a lot. Every cable type has its own good and bad points. Some cables use digital signals, but others use analog signals. Digital cables like hdmi and displayport show sharper pictures and brighter colors. Analog cables, like VGA, can lose picture quality and show more static. Let’s look at the main monitor cable types you might see today.

HDMI

HDMI means High-Definition Multimedia Interface. You use this cable for most TVs, monitors, and game consoles. It sends video and sound through one cable, so it is very popular. Over the years, hdmi has gotten much better. At first, it only worked with 1080p, but now it works with 4K and even 8K screens.

Tip: If you want to hook up a new monitor or TV, hdmi is usually the best pick.

Here is a table that shows how hdmi standards have changed and what they can do:

HDMI Standard	Bandwidth (up to)	AV Capabilities
Standard HDMI	4.95Gbps	1080p
High Speed HDMI	10.2Gbps	4K24, HDR, wide color gamuts
Premium High Speed HDMI	18Gbps	4K60, HDR, 4:4:4 chroma sampling
Ultra High Speed HDMI	48Gbps	Uncompressed 8K video - 8K60, 4K120

Newer hdmi cables can send a lot more data. This lets you get higher screen quality and smoother video. Hdmi also has features like HDR, which makes colors look more real.

The table below shows how hdmi versions have changed over time:

HDMI Version	Release Year	Key Features
HDMI 1.0	2002	4.95Gbps, 1080p, 8 audio channels
HDMI 1.1	2004	Added DVD audio and SACD audio formats
HDMI 1.2	2005	Enhanced audio support

HDMI 2.1	2017	48Gbps, 8K@60p, dynamic HDR, eARC support

Hdmi is now the main cable for most new devices. You can use it for computers, monitors, TVs, and projectors. Out of all monitor cable types, hdmi is the most used at home.

DisplayPort

Displayport is another digital cable you see with computers and fancy monitors. It looks a bit like hdmi, but it has some special things. Displayport can handle higher refresh rates and better screen quality, which is great for games and work.

Here is a table that compares displayport and hdmi:

Feature	DisplayPort 1.4	HDMI 2.0	HDMI 2.1	DisplayPort 2.1
Maximum Bandwidth	32.4 Gbps	18 Gbps	48 Gbps	80 Gbps
4K Resolution	Up to 120Hz	Up to 60Hz	Up to 120Hz	Up to 240Hz
8K Resolution	Up to 30Hz	Not supported	Up to 30Hz	Up to 60Hz
Unique Features	Supports DSC	ARC/eARC	eARC	Improved USB-C

Displayport lets you use more than one monitor with just one cable. This is called Multi-Stream Transport. You also get higher refresh rates, so games and videos look smoother. Displayport 1.4 can send 4K video at 144Hz, which is much better than old monitor cable types.

Note: Displayport is best if you want high refresh rates or more than one monitor.

DVI

DVI stands for Digital Visual Interface. You find this cable on older monitors and some graphics cards. There are two main types: DVI-D (digital only) and DVI-I (digital and analog). DVI can send a digital signal, but it does not send sound like hdmi or displayport.

Here is a table that compares DVI to other monitor cable types:

Feature	DVI-D	DVI-I	HDMI/DisplayPort
Max Resolution (Single Link)	1920x1200	1920x1200	Higher than DVI
Max Resolution (Dual Link)	2560x1600	2560x1600	Up to 8K
Analog Signal Support	No	Yes	No
Compatibility	Limited to digital devices	Compatible with analog/digital	Widely compatible
Use Case	High-res digital displays	Versatile for many monitors	Best for modern setups

DVI was better than VGA because it could send a digital signal. But it is not as fast or full of features as hdmi and displayport. You might still use DVI if you have an old monitor, but most new devices use other monitor cable types.

VGA

VGA is one of the oldest monitor cable types. It uses an analog signal, so the picture can get worse if the cable is long or there is interference. You might see VGA in schools or offices with old computers.

Here is a table that shows how VGA compares to digital cables:

Cable Type	Signal Type	Impact on Quality
VGA	Analog	Signal loss, noise, washed out colors, less sharp
HDMI	Digital	High quality, less interference
DisplayPort	Digital	High quality, less interference

• VGA uses analog signals, so colors can look faded.

• The picture is not as clear as with digital cables.

• Digital cables like hdmi and displayport give you a much better picture.

Alert: For the best picture, do not use VGA unless you have no other choice.

USB-C/Thunderbolt

USB-C and Thunderbolt are the newest monitor cable types. You see these cables on many new laptops, tablets, and monitors. USB-C can send video, data, and power all with one cable. Thunderbolt is even faster and lets you connect more than one device together.

Here is a table that compares USB-C/Thunderbolt to other monitor cable types:

Feature	USB-C/Thunderbolt	HDMI/DisplayPort
Resolution Support	Up to 8K at 60Hz with compression	Up to 4K at 60Hz (HDMI 2.0)
Data Transmission	10Gbps (USB 3.2)	HDMI 2.0: 18Gbps, DP 1.4: 32.4Gbps
Power Delivery	Up to 100W	None
Cable Compatibility	One cable for video, data, and power	Separate cables for video and power
Daisy-Chaining	Yes (Thunderbolt)	Limited (DisplayPort)

Many new laptops only have USB-C ports. You can use one cable to charge your laptop and send video to your monitor. Thunderbolt lets you connect more than one monitor or device in a row. These new monitor cable types make your desk look neat and simple.

Tip: If your device has USB-C or Thunderbolt, you get fast speeds, high screen quality, and easy setup.

When you pick a monitor cable type, think about your device, the ports you have, and the quality you want. Digital cables like hdmi and displayport give you the best picture and sound. DVI and VGA are older and may not work with new features. USB-C and Thunderbolt are the newest monitor cable types, giving you more choices and better performance.

HDMI and DisplayPort
