What is VGA port?
VGA port is a physical connection port , allowing the device to output images according to the VGA standard.
VGA stands for Video Graphics Array – a computer image display standard introduced by IBM in 1987. It allows simultaneous display of 256 continuously variable colors, on a screen with a resolution of 640 lines. horizontal and 480 lines vertically.
Advantages of VGA port
The VGA standard is compatible with all previous display standards , such as CGA, MDA, EGA,…
VGA cables can be used for many different resolutions.
The cost of VGA connection cable, replacing VGA port is very cheap.
VGA port is used very commonly , in most offices and schools, so it is very convenient and quick to use, not having to use a converter like other standards.
What limitations does the VGA port have?
Compared to later newer standards (such as HDMI, USB Type-C), VGA has inevitable limitations.
– The image quality and resolution are not high.
– Only transmits pure images, while HDMI, USB Type-C can output images and audio in parallel with a single cable.
– VGA port size is huge, twice as much as HDMI and even 4-6 times more when compared to newer standards, like USB Type-C.
The VGA port on the laptop has not really been completely replaced by the new connection ports later, the popularity of VGA is still very significant. However, one piece of advice for you is: you should choose to buy laptops with a new connection port instead of VGA and use it with a converter port (such as HDMI – VGA) when needed.
In conclusion, understanding VGA ports on laptops is essential for anyone who wants to connect their laptop to an external display or projector. VGA ports offer numerous benefits, such as easy compatibility with older devices and being widely available on most laptops. This versatility allows users to connect their laptops to various monitors, TVs, or projectors regardless of the connection type they offer. However, VGA ports also have their drawbacks. They lack support for high-resolution displays and don’t transmit audio signals. Additionally, the analog signals transmitted through VGA can result in compromised video quality. As technology advances, VGA ports are gradually being replaced with digital connectors like HDMI and DisplayPort. Nevertheless, VGA ports remain relevant for connecting to legacy devices or in situations where no other options are available. Overall, understanding the pros and cons of VGA ports empowers laptop users to make informed decisions when it comes to connecting their devices to external displays.
