Wow, I can't believe this. I have a Markus Ikea chair and a dual screen setup with a USB c hub connecting them all. The screen likes to turn off all of the time and it drives me nuts. A good smack quickly fixes it. I never considered the chair. Mind blown with static discharge.

You might want to look into some extra shielding for your mind. I hear having it blown by static discharge too many times can cause brain damage. ;)

In all seriousness, yeah, this is crazy! IMO, IKEA should either recall and fix, modify the design of, or stop selling these chairs. ESD can seriously damage equipment, and I could easily see there being cumulative effects from something like this.

I don't think it's classical high-voltage ESD reaching the monitor; it's RFI generating enough voltage to mess with the HDMI signal. Voltages generated by RFI will be relatively low compared to direct ESD.

I've got the exact same problem and now I'm nearly positive (ha ha) that it's being caused by my mesh-backed AmazonBasics chair. Truly one of the most personally useful posts I've ever seen on HN.
