HDMI Licensing Administrator shows 4K60 Premium Certified HDMI alt mode over USB Type-C Connector on a modified UHD Blu-ray player, by just re-routing the HDMI signal instead of going to an HDMI connector can transfer the same HDMI signal through the USB Type-C connector. For now devices like smartphones, tablets and PCs who want to be able to output HDMI signal over USB Type-C need to have a small chip to transfer the HDMI signal but later some SoCs might be adding this functionality directly onto the SoC.
HDMI Licensing Administrator shows some examples of the HDMI cables that get to be part of the Premium HDMI Cable Certification Program from such brands as Hama and Avinity brands which are popular in Europe, Rocketfish which is Best Buy's HDMI cable brand, blackweb and GE which are Walmart's HDMI cable brands and the affordable monoprice brand too.
The Premium HDMI Cable Certification Program is the new program from the creators of HDMI technology that encompasses additional and enhanced cable testing as well as an authentication and verification program. Cables are tested to ensure they support the full 18Gbps bandwidth from the HDMI 2.0b specification plus an EMI test to ensure cables minimize interference with wireless signals. The program is designed to give end users confidence when purchasing new HDMI cables for their 4K/UltraHD products that may include features such as 4K@60Hz, BT.2020 and HDR. Participating HDMI Adopters can promote their ATC-tested High Speed HDMI Cables as Premium High Speed HDMI Cables or Premium High Speed HDMI Cables with Ethernet using a unique anti-counterfeiting authentication label on their products which can be checked and authenticated using the app on any smartphone.

The HDMI Alt Mode for USB Type-C connector will allow HDMI-enabled source devices such as smartphones, tablets, laptops and camcorders to utilize a USB Type-C connector to directly connect to the Billions of HDMI-enabled displays (which is included with 100% of flat panel TVs), and deliver native HDMI signals over a simple cable without the need for protocol and connector adapters or dongles. HDMI Alt Mode will support the full range of HDMI 1.4b features such as 4K, surround, ARC, 3D, HDMI Ethernet Channel (HEC), Consumer Electronic Control (CEC), Deep Color, x.v.Color and content types, HDCP 2.2. HDMI Alt Mode follows all necessary Alt Mode USB Type-C specification requirements which auto-detects HDMI Alt Mode source devices and HDMI-enabled displays, requires no adapters to connect from an HDMI source to an HDMI display, source output is AC coupled for HDMI Clock and Data lanes and other.
HDMI 2.1 supports 4K120 and 8K60 uncompressed over a new 48Gbps cable, even supporting up to 10K 120fps compressed. HDMI 2.1 also supports Dynamic HDR, eARC and Game Mode VVR. Dynamic HDR enables variable HDR on a scene-by-scene even frame-by-frame basis. eARC enables object-based 3D audio. Game Mode VRR features variable refresh rate, which enables a GPU to display the image at the moment it is rendered for more fluid and better detailed gameplay, reducing or eliminating lag, stutter, and frame tearing.
