So folks, don't forget to check if your Ikea chair is compatible with your screen. I'm not kidding. A thread 🧵.
I've had the problem with my new screen for several weeks now, that every now and then the screen goes black for a few seconds.
Today I had enough and wanted to investigate the problem. So I started changing all the cables, plugging the screen into a different socket, and and and. Nothing helped.
The only correlation I could find was that the screen only goes off when my Ikea office chair is somehow involved.
So I suspected a loose contact somewhere. But no. No matter how much I wiggled the table/cables, everything was fine.
The problem was only there when I sat down or stood up, although the chair didn't even touch the table.
That was the moment I had my doubts. So I got another chair and tested it with it. No problem, screen stays on.
Took the Ikea "MARKUS" chair again, sat down - screen went off again.
HUH?! My chair has a feature that automatically turns screens on/off? I guess nice privacy feature?
I started to lose faith and couldn't find a logical explanation. So I searched the internet for "ikea markus chair screen problems" 🤦♂️
WAIT! I am not the only one with this problem!? Found the following (German) forum post:

It turns out that the fabric seat cover, and/or the gas suspension creates such a strong electrostatic discharge (ESD) that my screen shuts off for a short time.
The solution? No idea yet, but it seems that insulating the chair with copper foil and connecting it to a socket (ground) might help, as you can see here:

@haeckerfelix wait, what? 😳😅
I have the same issue! With a different chair, not from IKEA and only my main screen (the secondary one is identical though) shuts off randomly sometimes. Thought my GPU was bad or something, never could've thought it might be linked to the chair. 😅
