Yes, you can transmit data via HDMI to link two computers, similar to how Ethernet works. Since HDMI supports high bandwidth—around 50 Gbps—it could serve as a powerful networking channel. Explore HDMI over Ethernet setups or use HDMI as a physical media carrier for file sharing and streaming.
Unlikely to hear otherwise, particularly with standard gear. Key points to note are that HDMI doesn't support bidirectional 50Gbps transmission—data flows only in one direction from source to output.
Two HDMI cables linking the devices could ensure a stable connection.
It's worth mentioning that the HDMI cable itself isn't particularly advanced—it's simply a collection of wires connecting two points. What really matters is the equipment that powers the HDMI cable. Network cards handle significantly more tasks when managing 50Gbps packets versus a graphics card sending the same amount of video data. They need to manage queuing, communicate more often between computers, perform frequent handshakes to verify everything functions, and handle encryption, decryption of packet headers, and checksum verification. Consequently, only about 10Gbps of actual usable information is transmitted, not the full 50Gbps. In the case of Ethernet, this overhead makes it clear that combining two 10Gbps ethernet cables would yield better results than trying to force 50Gbps through a single cable with high overhead.
I don’t own any 10 gigabit NICs, yet even that speed surpasses anything else.
Be aware of this important note. To ensure the Ethernet link functions correctly, you need two devices that both support Ethernet via HDMI (they should be marked HEC compatible). This setup is still emerging, so many users are exploring it now. In essence, these future-ready cables aim to bridge present needs with upcoming technology.
