Gregory's Server@amxmln Is it possible that your second monitor is connected via DisplayPort?
I have the feeling that DisplayPort is more "sensitive" than HDMI in that regard.

 @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 I have the same screen connected to two computers, one via DP one via hdmi. Sometimes it blanks out via hdmi (especially when i feel a small electricity discharge) but never DP But it can also be cable quality @dt @amxmln @haeckerfelix Yeah, my USB3.0 to DVI adapter doesn't have any of those issues (compared to the HDMI to HDMI cable), but it might also have something to do with the position of the screen. Oh well, living on the edge... 😅 @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. @Htaggert @autiomaa @amxmln @haeckerfelix You are now known as Yoga Ball Woman. That is the Way. @autiomaa @amxmln @haeckerfelix @microChasm but but but I identify as a woman…. 😂😂🤷🏻♀️ @Htaggert @autiomaa @amxmln @haeckerfelix Oh my! I will edit that. My apologies. I obviously need to tap on the poster to see who they are and how they identify themselves when I am scroll posting. @amxmln @haeckerfelix @autiomaa @microChasm it’s ok. I can try to be a man! I just was laughing! @autiomaa @amxmln @haeckerfelix Could be the material in the feet (wheels?) of the chair and the floor interact to create static charge. I believe there exist floor coverings created specifically to avoid this problem. @hakona @amxmln @haeckerfelix Furniture ESD from chairs is difficult to "fix", as there are multiple different potential causes for it. It's not the floor covering, even while that can increase the risk. https://emcesd.com/pdf/eos93.pdf (PDF file, original article from 1993) tells that: "Normal methods of ESD control such as wrist straps, floor wax, as well as "ESD safe" chairs have no effect on this problem. Therefore an equipment problem may exist in a location and ESD not be suspected as the cause."  @djb @haeckerfelix @amxmln I'm not alone 🥳 My mom who sold these at work for some time told me that they sell special ESD-safe variants of the chair... which is mostly intended for highly sensitive areas but it seems like they're needed for us regular folx as well :') @ljrk @haeckerfelix @amxmln oh thanks for the tip. I'll see what I can dig up. Maybe I can modify it a bit. Hopefully nothing too ugly  @haeckerfelix I had major issues like this due to a cheap, badly shielded DisplayPort cable. Whenever a USB cable came in contact with it, the screen flickered or went off. Bought a bit more expensive one - problem solved. @haeckerfelix @amxmln wait is this why my screens randomly go black? I don’t have an ikea chair but I have the same issue. I use DisplayPort. |
@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. 😊
