Types of Ethernet VGA Cables
The Ethernet VGA cable uses a Video Graphics Array Connector, which was common in older monitors and still widely used in computers today. Ethernet transmits the video signal to the monitor and simultaneously returns keyboard and mouse clicks to the computer. Because it does this over long distances, it can stretch up to 300 feet.
The high data rates provide excellent video quality, so it is suitable for when clear pictures and videos are needed, such as when presented to potential clients in a conference room or in command centers. It is also necessary that people using computers on the same network can access needed data, even if they are not located at the same geographical location. Because the cable can transmit information over long distances, it can help in such situations. This Ethernet VGA cable can be run through walls, and there will not be any delays in data transmission. Another use can be security cameras that need to transmit data over long distances. The cable can help in such situations.
- Standard Ethernet VGA cable: This cable connects a computer's VGA port (Video Graphics Array) to a monitor or TV with a VGA port. The cable transmits video signals to display content. However, it can't carry audio signals, so a distinct audio cable must be added if sound is also needed.
- Ethernet VGA Cable with Audio: This Ethernet cable serves the same function of transferring video data from the computer to the monitor. Still, it also contains cables that can carry audio signals so that sound can be heard. The convenience of not having to use extra cables makes it popular.
- Ethernet VGA extenders: Long Ethernet cables can be used to connect distant locations on the network. These long cables cannot transmit high-quality images, though. A solution is to use extenders that can enhance the signal so that it travels greater distances. The extender and long cable work to provide connections to distant monitors.
- Active Ethernet VGA Cables: These cables have special chips that can enhance the signal and make it clearer. They are good for important tasks or presentations because they ensure the video quality is excellent and there are no problems with the connection.

Category (Cat) 6 and 7 cables are suitable for high-bandwidth applications, especially in companies, because they offer excellent performance over a long distance.
- Secure Connections: Since Ethernet cables use wired connections, they are generally more secure than wireless networks vulnerable to hacking or unauthorized access. Therefore, sensitive data, like financial transactions, are often transferred through Ethernet cables to ensure maximum security and confidentiality.
Functions and Features of a VGA Cable
- Visual Output: A VGA cable is primarily used to connect computers or other devices with video output to monitors or projectors. It carries video data to display images, videos, presentations, or other visual content. Besides that, the VGA cable can also connect devices like laptops, video graphic cards, or some gaming consoles directly to the monitor, providing a clear and sharp image.
- Analog Signal Transmission: While transmitting video data, the VGA cable converts the digital output from the source device into an analog signal. It may not be compatible with modern high-definition monitors. However, it can still deliver good picture quality for basic computing needs or standard-definition displays.
- Resolution Support: Despite being an older standard, a VGA cable can support various screen resolutions, including basic resolutions such as XGA (1024x768), SVGA (800x600), and SXGA (1280x1024). As a result, the VGA cable can deliver decent resolutions for typical business applications, multimedia, and gaming.
- Limited Sound Transmission: A typical VGA cable does not transmit audio signals. Therefore, to enjoy sound while watching a video or listening to music, a separate cable like an audio cable or HDMI cable must be used. VGA cables can create confusion for users because they don't carry audio signals, so they are not compatible with devices that only have an audio output.
- Common Connectors: The most common VGA cable connectors are 15-pin HDDE, which connect to devices such as older monitors, projectors, TVs, and computers. The cable has three color-coded (red, yellow, and white) RCA connectors to merge into the composite input of a television or projector and an additional 15-pin connector to connect to the computer or monitor.
Scenarios of Ethernet VGA Cable
Applications of Ethernet VGA cables vary widely and can connect many devices for various purposes.
