Key Takeaways

  1. HDMI cable transmits digital signals and can carry high-quality video and audio signals.
  2. AV cable, on the other hand, is an analog cable that transmits analog signals and does not support high-definition video and audio.
  3. HDMI cable provides a better overall viewing experience due to its ability to transmit high-quality digital signals with less interference.

HDMI Cable vs AV Cable
