  1. Signal type
  Lightning cable: Lightning cable is a digital signal transmission, support high-definition video and audio transmission.
  VGA cable: VGA cables transmit ana-log signals and are suitable for low-resolution video transmission.
  2, transmission speed
  Lightning Cable: The latest generation of Thunderbolt 4 supports transmission rates of up to 40Gbps, ensuring high-speed data transfer.
  VGA cable: Because VGA cables transmit ana-log signals, the transmission rate is low and is greatly affected by the cable quality and length.

  3, picture quality performance
  Lightning cable: Due to the use of digital signal transmission, lightning cable can achieve high-definition picture quality, to bring you a more real and delicate visual experience.
  VGA cable: Due to the use of ana-log signal transmission, the picture quality of VGA cable is limited by resolution and cable quality, and is relatively poor.
   4. Compatibility
  Lightning cable: Lightning cable is compatible with USB-C interface and can be used for devices that support USB-C, such as laptops, tablets, and smartphones.
  VGA cable: VGA cable is mainly used in the connection between the old computer and the monitor, with the development of technology, VGA interface is gradually replaced by a new interface.
  5. Application Scenarios
  Lightning cables: Lightning cables are used in high-speed transmission scenarios, such as audio and video production, external monitors, and data storage.
  VGA cable: VGA cable is mainly used in the connection between older computers and monitors, and other occasions requiring lower resolution video transmission.
  There are significant differences between lightning cable and VGA cable in signal type, transmission speed, picture quality, compatibility, and application scenarios. Lightning cable has higher transmission speed and picture quality performance, suitable for high-speed data transmission and high-definition picture quality requirements of the scene. In contrast, VGA cables are suitable for lower resolution video transmission, mainly used in the connection between older computers and monitors.
