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.

3Yeah... It's possible, but you'd have to do some pretty low-level hacking (possibly even writing custom drivers?) to pull it off. Commented Mar 1, 2011 at 12:20

2HDMI does potentially provide an Ethernet channel so that internet-enabled home theater equipment can have a one-cable solution (hdmi.org/manufacturer/hdmi_1_4/hec.aspx) but Ethernet over HDMI doesn't even come close to the available bandwidth of the HDMI interface. Commented Jun 13, 2012 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...– polemonCommented Jun 13, 2012 at 17:18

I too am interested in this. This is the highest bandwidth interface easily available to the consumer.– Milind RCommented Dec 27, 2013 at 8:07

what do you mean by packet streams? how would this be a drawback more specifically?.. Commented Sep 7, 2016 at 16:42
This doesn't practically help you, but apparently HDMI is being used to stack switches now:

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.

1Can the HDMI ports on notebooks receive media signals in a way that is accessible to the end-user (or developer), then?– bertiebCommented Aug 18, 2018 at 19:07

@weberjn Unless the laptop has been sufficiently modded (custom drivers maybe?), no. Commented Mar 17, 2019 at 19:05
