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.
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)
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. 😅
@haeckerfelix My primary screen (the one which shuts off) is plugged in via HDMI and the secondary (which remains on) via Display Port—but the secondary screen is further away from my chair than the primary one. 🤔
I’ll keep an eye on whether or not I can reliably reproduce it now that I know it might be the chair. 😊
@amxmln@haeckerfelix HDMI seems to be more sensitive to interference. I have two external displays on a laptop, and only of of those gets blanked frequently. Larger display has longer cable, so that might be part of the reason why it's more sensitive to any issues. Maybe better cable quality might reduce part of the issues, as some of the thinner cables don't have that much insulation.
But seriously, the chair is likely to the blame, not the cables. Floor covering might also matter a bit, too?
@autiomaa@amxmln@haeckerfelix that whole thing is just Wow! I would not have figured out the connection! Luckily for tre past 7 years I’ve relied on a Yoga ball for computer seating.
@amxmln@haeckerfelix Same here, only my main screen is affected. I also have dual-screen and both are connected with top-notch Club3D DP cables. Doesn't help against the Zeus-like power of the IKEA Markus with fabric, obviously... :<
@haeckerfelix I don't think you need to connect it to the ground; connecting appropriate two parts of the chair together should suffice. I would expect that the chair is not discharging any if that charge into air (it didn't have any spiky parts after all).
@haeckerfelix@olasd I've been seeing this at home as well; moving from a Dell laptop, its dockstation, and DisplayPort to a different brand/model, without dockstation, and HDMI (with the same screen as before). With an X-chair by Milani.
Oh my god! I've been facing similar issues with my Ikea chair. Initially, I thought the reason behind it was the ungrounded sockets in my room.
Whenever I try to move the chair after standing up, it's always a bit of a gamble whether I'll get a shock or not from touching the back-leaning part. It's become a bit of a game for me, in a way.
However, since this chair has already given up on me, I'm considering buying a new one. It's reassuring to know that I'm not the only one dealing with these problems. 😆
@haeckerfelix I think I got a screen gifted to me thanks to this.
Someone claimed that this screen wouldn't be working correctly anymore and I said I'll take it
Works perfectly fine for me!
They have such an IKEA chair :D
@haeckerfelix I love ESD and other EM weirdness... People underestimate what a wild zoo their homes can be. I have these bluetooth headphones that somehow pick up everything, turning things on and off always gives me some static... and I remember I had an old FM radio that was able to notice all kinds of weird shit too.
@apodoxus
Medium wave radios (aka AM radios) may pick up noise from electric discharges in their environments, especially if tuned to the "static" (sic!) between stations. These might give you a somewhat sensitive detector. @haeckerfelix
