The features of Ultra High Speed HDMI Cable comply with Category 3 Cables specifications as stated in the Compliance Test Specification (CTS). The UHS cables support up to 48Gbps bandwidth, 4K@12Hz and 8K@60Hz, and other HDMI 2.1 features such as eARC, VRR, and HDR.

Requirements of Ultra High Speed HDMI Cable Certifications:

  1. All tests need to be conducted at HDMI ATCs (Authorized Test Centers)
  2. Implementation of Certified Category 3 Connector
