How to Choose the VGA Cables
Are you curious about how video signals are transmitted between hardware devices? A Video Graphics Array (VGA) is a device that is used to send video signals from computers to monitors or televisions. These signals are transmitted via cables that utilize electronic signals and data. The most common type of signal is a video signal, which is composed of the red, green, blue, and horizontal signals.

What are VGA cables?
VGA (Video Graphics Array) cables are a type of video cable commonly used to connect computers, laptops, and other devices to displays such as monitors, projectors, and TVs. VGA cables have been widely used in the past for analog video signals but have become less common in recent years due to the increasing prevalence of digital connections like HDMI and DisplayPort.
What does VGA cables consit of?
VGA cables typically consist of a male VGA connector at each end. The connector has 15 pins arranged in three rows, with five pins in each row. The cable carries analog video signals and does not transmit audio. To transmit audio alongside video, you would need a separate audio cable or use a different video interface that supports audio transmission.
How to use VGA cable?
To use a VGA cable, you would connect one end of the cable to the VGA output port on your computer or other device, and the other end to the VGA input port on your display device. Once connected, you may need to adjust the display settings on your computer to ensure it recognizes the external display.
Why should use VGA cables?
While VGA cables are gradually being replaced by digital video connections like HDMI and DisplayPort, there are still a few advantages to using VGA cables in certain situations:
Wide Compatibility
VGA is a widely supported standard that has been used for many years. Most computers, laptops, and older display devices have VGA ports, making VGA cables compatible with a wide range of devices. This can be useful when connecting older or legacy equipment that doesn't have digital video outputs.
Cost-Effective
VGA cables are generally more affordable compared to digital video cables like HDMI or DisplayPort. If you have a limited budget or don't require high-resolution or audio transmission, VGA cables can be a cost-effective option for basic video connections.
Simplicity
VGA is a straightforward analog video connection. It doesn't require complex digital protocols or encoding/decoding processes. This simplicity can make VGA connections more reliable in certain scenarios, especially in situations where you need a simple and direct video connection.
Longer Cable Runs
VGA signals are analog and can be transmitted over longer cable distances compared to some digital connections. This can be advantageous when you need to connect a device to a display that is far away, such as in classrooms, conference rooms, or large event spaces.
Legacy Support
VGA is still commonly used in some industries and applications that rely on legacy systems. For example, in industrial settings or specialized equipment, VGA may be the primary or only video connection available. Having VGA cables on hand allows you to connect to and maintain compatibility with such systems.
Limitation of VGA cables
While VGA cables have their advantages, it's important to note that they have limitations compared to digital connections. VGA is an analog signal, which can be prone to quality degradation over longer cable runs and is limited in terms of resolution support. Additionally, VGA cables do not carry audio signals, so a separate audio connection is required for audio transmission.
If your devices and displays support digital video connections, it's generally recommended to use HDMI or DisplayPort for better image quality, higher resolutions, and audio transmission capabilities.
How to choose VGA cables?
When choosing a VGA cable, there are a few factors to consider to ensure you get the right cable for your needs. Here are some considerations:
Cable Length
Determine the distance between your computer or device and the display you want to connect. Measure this distance and choose a cable length that allows for easy connection without unnecessary cable slack. Keep in mind that longer VGA cables may result in signal degradation, so it's best to choose the shortest length that meets your requirements.
Cable Quality
VGA cables come in various quality levels. Higher-quality cables generally have better shielding to minimize interference and signal degradation. Look for cables with thicker, well-insulated wiring and multiple layers of shielding for optimal performance. It's worth investing in a good-quality cable, especially if you're planning to use it for high-resolution displays or in environments with potential electromagnetic interference.
Connector Types
VGA cables typically come with standard VGA connectors on both ends. Ensure that the connectors are compatible with the VGA ports on your computer or device and the display you want to connect. VGA connectors are usually male, but some cables may have a female VGA connector for extension purposes.
Resolution Support
Determine the maximum resolution your devices support and choose a VGA cable that can handle that resolution. Most VGA cables support resolutions up to 1920x1200 pixels, but if you have a higher-resolution display, you may need to consider other video connection options like HDMI or DisplayPort.
Additional Features
While VGA cables primarily transmit analog video signals, some cables may have additional features like built-in ferrite cores or gold-plated connectors. These features can help reduce interference and improve signal quality. While they are not essential, they can be beneficial in certain situations.
Price
VGA cables are generally affordable, but prices may vary based on cable quality, brand, and additional features. Set a budget and choose a cable that fits within your price range while still meeting your requirements.
It's worth mentioning that VGA cables are becoming less common, and digital video connections like HDMI and DisplayPort are more prevalent. If your devices support digital video output, consider using those connections instead for better image quality and compatibility with modern displays
