HDMI 1.3 bandwidth is over 10G. Notebook nowadays has HDMI port available. Is that possible that we use HDMI cable to hook up 2 notebook and perform file copy operation?
It's technically possible, as HDMI is a bidirectional interface. however, it is designed for packet streams, and not data blocks.
So, in a practical sense, from a users perspective: No, it's not possible.
This doesn't practically help you, but apparently HDMI is being used to stack switches now:
"2 Stacking Ports (HDMI)"
It is possible, there are HDMI cables that support data, or even "internet" sharing. Both devices must have support for data transfer.
No its not currently possible to do that, HDMI (High Definition Multimedia Interface) is for video & audio streams only
No. HDMI is a media cable only.
In theory, you could encode said data into some form of media (audio, video, ) and transfer it through the HDMI and decode it on the target computer.
But it’d be much easier to upload the file to the cloud (Google drive, Dropbox, etc) and download it on the target computer.
