Are you a computer geek or a lover of the computer world and want to know about the thing that connects some significant components of the computer, i.e., different computer monitor cable types and their connectors?
In this article, you will know about the different types of cables and connectors. You will also get to know how to connect the laptop to monitor and much more in this regard.
Some of the main points discussed in this article are:
- Definition of cable
- Monitor connection types
- HD 15
- How to Connect the Laptop to Monitor
Before moving towards the main topic of the article, I guess I should give you some introduction to cables too and let you know what really cable is.
What is the Definition of Cable?
These are the insulated wire that transmits the electricity. There is a plastic covering around the cables.
They are also known as:
Types of Computer Cable:
Two main types are:
1) Data Cables:
It provides a mean of communication between various computer components.
Some popular ones include
2) Computer Power Cable:
It provides power to the device
What Types of Computer Monitor Cables are there?
In this technological era, it is quite essential for you to have a good knowledge of computers. While using desktop computers, you will have to work with the cables too to attach different devices.
Following are some essential cable types that you will have to use while working with computers:
- USB Cable
- HDMI Connector
- HD 15 Monitor Cable
- DVI cable
1) VGA Cable:
VGA stands for video graphics array.
- They were introduced in 1987 by IBM.
- It is used to transfer the video signals.
- It carries the electronic signals from one hardware device to another.
- Its function is to connect analog PC monitor to a laptop or a PC. It uses an HD15 connector to connect the monitor to the PC
- Pins are present on the inside of the plug. These pins fit into the hole pattern that is present on the backside of the computer.
To identify them you can look at the pins inside the plug. VGA cables have mostly 14 pins on the inside.
- All PCs have VGA installed in them.
- Thet gave the capability of displaying the video even without installing the drivers,
VGA vs. SVGA Cable:
VGA is the Video Graphic array while SVG stands for Super Video Graphics Array
VGA supports video resolution up to 640 x 480 while SVGA can have a resolution of 800 x 600
Thickness and Shielding:
SVGA has more shielding than the VGA cables. This shielding is the reason that they are a bit thicker than the VGA.
SVGA cables perform well for long distances.
For devices that are much closer to each other, you will most probably need the VGA cable. In such cases, buying an SVGA cable will be a wastage of money.
2) USB Cables:
USB stands for the universal serial bus. It is now widely used in the computer peripherals.
USB is primarily an industry that came up with a goal to standardize the computer peripheral for the computer connection.
Many computer components in the modern times have some form of USB cables and connections.
- Their primary use is to connect the computer to the camera, mobile phones and another device of this sort.
- You can also use it to connect the computer to any secondary display device.
- Well, it is better not to use it to connect to the monitor. The reason is that the USB cables have a limited resolution, i.e., 1024 x 768.
- These cables work for replacement screens for laptops.
Types of USB Cable Connector:
You might be thinking that by name its universal then how its three types came?
Well, these it has different types because each of these types offers different functionality. They all perform various functions.
Some of these types are:
- USB 2.0 Type-A
- USB 2.0 Type B
- Mini USB 2.0 type B

- Thus they are compatible with the earlier version too.
- Modern laptops have this connector.
f) USB 3.0 Type B:
- Modern laptops have this connector.
- This one is a bit different from the type B of the earlier version, and that’s why it cant be used in USB2.0 type B plugs.
- It works well with the higher performance devices.
g) Micro USB 3.0:
- It provides much higher data rate as compared to the earlier version micro USB, i.e., micro USB 2.0.
- You can use old concestor of this type in the new plugs but not the new ones in the old plugs.
Micro VS Mini USB:
Many people get confused between these two connectors. Well, you need not be complicated anymore.
The first one is larger in dimension than another one.
3) HD 15 Monitor Cable:
HD 15 is the most commonly used one.
- This cable is referred to as the standard VGA cable.
- It is mostly blue.
- Its responsibility is to communicate the image data.
- It is a universal connector that is used as the video interface for PCs.
- HD displays, satellite receivers, and cable boxes also use it.
- The HD15 connector has 15 pins that are arranged in a row.
- Each row consists of 5 pins.
- It is also called HD DB15. This is because it is a high-density D style connector.
Its one drawback is that the resolution features are limited. The resolution of 640×480 is supported. This resolution value is the reason it cant be used in the new devices and gadgets that need high resolution.
4) DVI Cable:
Full form of DVI is Digital Video Interface. It is one of the most common technologies used for the video display across LCD monitors.
- This one provides a complete solution as it can communicate digital and analog data.
- Modern devices use this type of cable to connect to the digital monitor.
- It also can reduce the digital noise in LCD.
It can support the following resolutions:
- 2560 x 1600 video resolution
- 1920 x 1200 image resolution
DVI vs VGA:
You might think that it resembles the VGA cables. Well at first glance it might look similar to the VGA cable, but in reality, it isn’t.
The difference is that it has longer flat pins as compared to VGA.
- The maximum length is not an exact value. The reason is that the manufacturers are trying their best to provide the best quality output and for this, they go for stronger cables.
- The minimum length that they should maintain is 5 meter approx.
- One more thing that you should note is that if you use DVI-I cables of extended length, then you will not be able to see an excellent quality display.
Types of DVI Monitor Cable Connectors:
It has following categories:
- DVI-D-True Digital Video
- DVI-A- High Res. Analog
- DVI-I – Integrated
a) DVI-D-True Digital Video:
- It has three rows. Each row with eight pins.
- To connect a DVI computer to another DVI monitor, you will need DVI-D cable.
- Their primary task is to provide a faster and a higher quality digital connection between the video source and the monitor.
How DVI-D Works?
- First, a digital video signal is reduced by the video card.
- Then this digital video signal is converted into the analog at the VGA output.
- Then this signal (that is now the analog signal) is converted again into the digital signal when it goes to the monitor.
Thus DVI-D works in eliminating this analog conversion process and provides a higher quality connection in between the two devices(the source and the display).
b) DVI-A- High Res. Analog:
- It consists of 17 pins and carries the analog signals.
- If you intend to connect a DVI monitor to a VGA monitor, then you will need this type of cable.
- They carry the DVI signal to the analog display.
- They are mostly used in connecting to the device with the VGA connector.
c) DVI-I – Integrated:
They are the integrated cables that can transfer the following:
- A digital to a digital signal
- An analog to an analog signal
5) HDMI Cable:
- HDMI stands for High Definition Multimedia Interface. Modern computers now have the HDMI port.
- It consists of 4 shielded twisted pairs
- This cable is also found in many home theatre and LCD televisions.
- It is an interface that transmits uncompressed and decompressed audio and video data to a monitor or any projector.
- Its many versions have been introduced.

Which Cable to Use Among Different Monitor Cable Types? – A Tough Decision:
After reading about all the types of DVI cables, you must be thinking which one to use?
Am I right?
Well, it is bit critical situation too, but you don’t need to be confused in this regard.
The first thing you need to do is to check the female DVI plugs and see their compatibility signals.
- You will need a DVI-D cable if you see both the connector or any one of them as a DVI-D cable.
- If both or any of them are DVI-A, then you will need a DVI-A cable.
- You will need a DVI to VGA cable if one connector is DVI and the other one is the VGA.
- And last but the most important one. If one is analog and the other one is digital, then you cant connect the two with anyone cable. For this connection, you will need a converter box.
