Vga Video Hd Cable 1080vga 3+6vga
New Products From This Supplier
1. Working principle:
The VGA cable reproduces colors by transmitting the three primary color signals of red, green and blue (RGB) and synchronization signals (horizontal synchronization and vertical synchronization signals). Since it is an analog signal transmission, signal attenuation and distortion may occur after long-distance transmission or multiple transfers.
2. Features:
Compatibility: The VGA cable has good compatibility and can connect most computer monitors, projectors and other devices with VGA interfaces.
Simple and convenient: The connection method is simple, no additional driver or setting is required, just plug the two ends of the cable into the corresponding interfaces of the display device and the video source device respectively.
Low cost: Since VGA technology is quite mature, the cost of VGA cables is relatively low.
3. Resolution support:
The VGA cable supports multiple resolutions, including the common 640x480, 800x600, 1024x768, 1280x1024, etc. However, for higher-resolution display devices (such as 2K, 4K, etc.), the performance of VGA cables may not be satisfactory, because analog signal transmission is prone to distortion at high resolution.
4. Limitations:
Signal attenuation: Since VGA cables are analog signal transmission, signal attenuation and distortion may occur after long-distance transmission or multiple transfers.
Resolution limitation: For high-resolution display devices, VGA cables may not perform as well as HDMI or DisplayPort cables that transmit digital signals.
No support for audio transmission: VGA cables are only used for video signal transmission and do not support audio signal transmission. If audio and video signals need to be transmitted at the same time, an additional audio cable is required.
5. Alternative technologies:
With the continuous development of digital display technology, digital signal transmission technologies such as HDMI (High-Definition Multimedia Interface) and DisplayPort have gradually replaced VGA technology. These digital signal transmission technologies have the advantages of higher bandwidth, lower signal attenuation and distortion, support for higher resolution and audio transmission, etc.
6. Application scenarios:
VGA cables are still widely used in various occasions where computer monitors, projectors and other devices need to be connected. However, in situations where higher resolution, lower signal attenuation and distortion, support for audio transmission, etc. are required, HDMI or DisplayPort cables may be more suitable.
