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.

Yeah... It's possible, but you'd have to do some pretty low-level hacking (possibly even writing custom drivers?) to pull it off. – Dave Sherohman Mar 1 '11 at 12:20
HDMI does potentially provide an Ethernet channel so that internet-enabled home theater equipment can have a one-cable solution ( but Ethernet over HDMI doesn't even come close to the available bandwidth of the HDMI interface. – Stephanie Jun 13 '12 at 13:09
@Stephanie I believe this is due to wrapping Ethernet packets into HDMI packets. When lengths are not equal, they'd have to be split and rearrange, possibly buffered. I's just assumptions, though. I don't think that that kind of equipment comes with TCP stacks, it's probably implemented in firmware... – polemon Jun 13 '12 at 17:18
I too am interested in this. This is the highest bandwidth interface easily available to the consumer. – Milind R Dec 27 '13 at 8:07

This doesn't practically help you, but apparently HDMI is being used to stack switches now:

"2 Stacking Ports (HDMI)"

Just to let you know I shamelessly copied one of your blog posts in my answer here. – terdon May 5 '13 at 21:16

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.
