Monitor Cable: What You Need To Read

Computer cables come with a set of standards and uses. Therefore, it cannot be obvious to understand their purpose. Monitor cables connect the monitor to a power source. In the case of a computer, it is a CPU.

What are the other purposes of a monitor cable? Are they of different types? Which type of monitor cable is the best for a computer? Where to custom a monitor cable?

In this article, you will learn everything that you need to know about monitor cables.

Chapter 1 – About Monitor Cable

Monitor cables are essential for computers. However, they are useful for all kinds of monitors. This includes televisions, display machines, ultrasound machines, and more.

All of these machines need a display unit. This display unit has a power source connected to it, which helps it display its readings. A monitor cable, thus, is essential for the functioning of any display unit.

There are several kinds of monitor cables, but their primary purpose is to display the images. All of them carry digital video signals on them and help with the display of the computer.

A monitor cable is primarily used to connect a computer with a display device. It can be of different kinds for different machines, but their purpose is the same. A monitor cable is a carrier of visual display data. It has connectors at each end and connects the graphics card of a system with its display unit.

The card on the motherboard sends these signals via the cable, and the monitor registers them. The cable can be of various types, depending upon the quality of video or display they offer.

The data that a monitor cable receives is analog. It then converts it into digital/video data so that the monitor can display it. The power source sends sync signals, which are of the vertical and horizontal types. For a television, many of these signals combine to form a singular composite video signal.

But a computer monitor can separate all of them and hence, has more pixels than a TV set.

The types of cables are VGA, DVI, HDMI, Display Port, and USB. Out of these, HDMI is the most popular and compatible monitor cable. Not only can it connect your computer monitors but also TVs and other screens. Monitor cables connectors help connect incompatible display units to others. They can also connect incompatible display units to power sources.

Chapter 2 – What is Digital Video Interface?

A digital video interface also connects a computer to its power source. However, as compared to other cables, it keeps the signal digital at both ends. Digital video interface works is an industry-standard for digital video content.

The DVI can support multiple mediums like analog, digital, and digital, and analog. It is compatible with many other monitor cables and is thus, very versatile.

The digital video interface is a popular choice for connecting computer monitors. Apart from monitors, it is also used for the connection of television sets and DVD players.

Chapter 3 – Types of Monitor Cable

There are many types of monitor cables available based on their function. The different wires also determine the quality of the video on your display unit. The different types of monitor cables are as follows:

VGA Cable – VGA or Video Graphics Array is one of the oldest kinds of monitor display cable. It is commonly used for CRT monitors and LCD computer monitors. A VGA cable features two ends, one with a 15-pin connector and another with 15 small holes. People initially designed these cables for lower-quality displays.  This is why many LCD monitors attached with a VGA cable show some fuzziness in the picture quality. They generally support a 640 x 480 resolution.

DVI Cable – DVI cables look like VGA cables but do not cause the same visual noise. A DVI cable can feature up to 24 pins on each end for the digital video signals and have four more for analog. It can support a screen with a resolution of 2560 x 1600.

HDMI Cable – HDMI cables are the most commonly used monitor cables these days.

They are compatible with every video component of the modern entertainment system. The new computer monitors also support HDMI, making it easier to connect them to any system. The cables are now a digital standard due to their popularity and affordability.

HDMI cable in use

The cable is capable of carrying sound information, making it even more functional! An HDMI port features 19 pins and is much smaller than VGA and DVI. HDMI cables can connect televisions, monitors, 4K screens, and more.

Display Port – Display Port is a new type of monitor cable. They offer the same quality as any DVI or HDMI cable but are mostly compatible with Apple products. They are also compatible with computing devices of different brands. However, Display Port might not be the only port on those devices. If you have a Display Port to connect to an incompatible device, you will need an adaptor.

USB Cable – Some monitors are compatible with the standard USB cables. These cables are the easiest to identify and the most affordable of the lot as well.

However, monitors connected with USB cables do not have the best resolution. This is why people who want excellent visual quality do not prefer them either. However, USB is the best solution when you need to connect your monitor on the go.

Chapter 4 – Which Type of Monitor Cable in the Best?

You may assume that the more expensive cable would always guarantee the best quality. However, unless your data is analog, it won’t make a difference. Digital cables transfer data in segments from one end to another. Therefore, the price of the cable doesn’t make a difference. You get the same video quality for any wire that you pick. However, the type of cable that you choose determines the quality of the video. It also determines how many devices your monitor is compatible with.

HDMI works as a default connector in most of the display devices that we use today. It is thus, the best monitor cable and connector to use. It can work with most devices and screens, HD content, and Blu-ray as well. The cable is capable of carrying both video and audio signals.

However, if you already own a DVI or VGA run device, you shouldn’t purchase one with an HDMI port. A cable doesn’t necessarily affect the quality of the video for a big screen. But for a smaller screen, the faster the cable transfers data, the better.

Chapter 5 – Monitor Cable Converters

Sometimes, the ports of your monitor and power source are incompatible. For example, your power source or CPU has a VGA port, but the new monitor that you bought has an HDMI one. To resolve this issue, you will need a monitor cable converter. Here are the types of converters that you can choose from:

VGA to HDMI converter –.  This converter will change the VGA signal from your laptop or desktop to an HDMI signal. The HDMI end of this cable is useful to connect to a TV or another monitor. This converter also helps if you have a VGA signal for your video card but an HDMI one for the display.

HDMI to VGA converter – This converter can connect a new laptop or desktop to one with an older display. It connects an HDMI video card port to a TV or a monitor with a VGI port.

DVI to VGA converter – DVI to VGA converters typically have DVI male and VGA female. This means that the DVI port of the converter is for the video card input, while the other end is VGA for the display. However, a male-to-male VGA cable connects the female VGA port with the display system.

VGA to DVI converter – These converters are very hard to find. They transfer the data from a source with a VGA port to a display unit with a DVI port.
