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.#ikea #chair #hardware #weird

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: https://www.computerbase.de/forum/threads/hauptmonitor-wird-sporadisch-kurz-schwarz.2060771/

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. 🤦♂️ Welcome to 2023 - Your Ikea "MARKUS" chair is not compatible with your screen 👏(Not my chair, the picture is from the forum post)#ikea #chair #hardware #weird

@haeckerfelix eh, one of my external screens turns off for .5s when I turn on the light next to it, or sometimes when my fridge starts…

@haeckerfelix i developed a habit of grounding myself right after I get up to ensure that I don’t have any ESD on me. in my case, it seems that the discharge is caused mostly by my long hair rubbing against the back of the chair :p

@haeckerfelix I just found your post after having similar issues with my Ikea Järvfjället chair. My display is not affected, but my wired Audeze headphones! With the dry weather of the previous weeks I have to put them down before standing up, otherwise when I return to my chair, I get static noise jumping 2-3 times between the left and right ear. Another pair of headphones (Hifiman) doesn't have this issue, even though both use the same technology (planar magnetic drivers). 🎧 ⚡ 🪑

@haeckerfelix there is a 10mins video about this exact problem encountered by a French streamer: he tries and experiments things, and he watches other people having the same problemhttps://youtu.be/PLs2ibJf6jo?si=O_H1Fu03mCriWV-C
