  Thunderbolt cable and HDMI cable are commonly used video transmission cables, they have their own advantages in data transmission, audio and video transmission.
HDMI cable
  1. Data transmission speed
  Lightning cable: Lightning cable data transfer speed is very fast, the latest generation of Thunderbolt 4 (Thunderbolt 4) supports transfer rates of up to 40Gbps.
  HDMI cable: HDMI cable transmission rates are relatively low, the latest HDMI version 2.1 supports transfer rates up to 48Gbps, but many devices still use lower HDMI 1.4 or 2.0.
  2, audio and video transmission capability
  Lightning cable: Lightning cable can transmit high-definition video signals, while supporting audio transmission. It can realize high-definition picture transmission between multiple monitors, and is suitable for various high-definition video application scenarios.

  HDMI cable: HDMI cable uses an independent interface design and is incompatible with other interfaces. Most TVS, monitors, game consoles and other devices support HDMI interfaces.
  4, power supply capacity
  Lightning cable: In addition to data and video transmission, lightning cables can also provide power for connected devices to charge them.
  HDMI cable: HDMI cables are mainly used for audio and video transmission and cannot provide power for devices.
  In summary, there are certain differences between lightning cables and HDMI cables in data transmission speed, audio and video transmission capacity, compatibility and power supply capacity. You can select cables based on actual requirements and device features. If you need high-speed data transfer and device charging, lightning cable is a better choice. If your needs are mainly audio and video transmission, HDMI cable is a more suitable choice.
