What Happens If You Cut Wires in HDMI Cable?

In the HDMI cable you have 8 cables (4 twisted pairs) that send image/sound data. The others are basically detecting that you turned on a device and perform a handshake to check that the HDCP encryption is established before sending image, so if you don't interrupt the connection you still have data but you cannot reestablish the connection without them. On the plug you also have 4 pins I think that are ground for the shielding. Although not explained in the video, it answered my question for what I was trying to do, nice video.

HDMI is packed full of many options of data and control. It’s more than just a video cable or a way to hook up a monitor. There’s sometimes power, control for other equipment. You have enough to make the monitor work with all those wires cut, but HDMI does a lot more than the things you are testing for.

Although this wasn't quite what I was expecting when searching for an answer to a technical issue I'm having it actually answered my question just fine and to boot was a joy to watch. Especially liked the "red looks important" bit. Cheers.

I Just loved this video...thank you for making this...so innocently you have shot this video....i guess you yourself do not realise what a great thing u have done!! thanks

I liked the way you explain the video, I will apply it with our students. thanks from mexico

How do you use the lighter? just heat up and pull the plastic cover?

Gd experiment... now we know wat happens and we can try other experiments based on these

Some of the wires are probably there to identify the display and It's specs. So after connecting and knowing what type of display it is, it doesn’t need them anymore until reconnected.

nice video. what if using rg45 wire (lan) to extend it. ab 5 - 10 meter'or more. cut the original hdmi, and join with lan wire in between ? thanks

Very nice experiment. It also tells how HDMI works.

Hi sorry is it possible to identify the audio wires between the 20 wires that make up the cable? Which colour has It?

How can we made HDMI2 audio video cable?

Hi. Do you know if the AUDIO can disappear by cutting one of the Wires?

I thinks there's something like a digital synchronisation applied to the six or four wires including red blue green and yellow or purple wires whoes duty is to transmit colours as digital data i think is called TMDS or something unlike the rgb or vga cables that if for instance you cut red wire in that connection only the red colour disappears in the screen and in digital colour transmission disconnecting a single wire of any colour would mean a lack of a digital colour synchronisation in the receiver so it results in black screen after cutting one of those wires
