I'm sensitive to EMI but never thought I'd have a reaction to using an HDMI cable although it was the first thing I tried. Immediately after connecting to a computer and a monitor, I felt bad. Will have to use a VGA cable again. I couldn't believe I would react that badly so I researched this and found articles stating that in many cases HDMI cables are not properly shielded as there is no standard for it. So unfortunately I have to send it back. If you have trouble with it I wouldn't use it, but even if you don't I would consider to consider this as well as the radiation from Wi-Fi. We may be insensitive at the moment, but it can build up.
