This reminds me of the "my monitor blinks every time I sit down in my office chair" turning out to be EMI spikes from the gas lift affecting the signal traveling on monitor cables.
A DisplayLink KB article even mentions it (and the associated white paper about the issue), stating:
Surprisingly, we have also seen this issue connected to gas lift office chairs. When people stand or sit on gas lift chairs, they can generate an EMI spike which is picked up on the video cables, causing a loss of sync. If you have users complaining about displays randomly flickering it could actually be connected to people sitting on gas lift chairs. Again swapping video cables, especially for ones with magnetic ferrite ring on the cable, can eliminate this problem. There is even a white paper about this issue.
- valbaca 3y agogot a link to the whitepaper? or name?
- kup0 3y agowoops, yeah I should have linked the DisplayLink article and whitepaper both probably, was just going quickly DisplayLink Article: https://support.displaylink.com/knowledgebase/articles/738618-display-intermittently-blanking-flickering-or-los https://support.displaylink.com/knowledgebase/articles/73861... Direct whitepaper link (warning: PDF): http://www.emcesd.com/pdf/eos93.pdf http://www.emcesd.com/pdf/eos93.pdf - if people prefer to search themselves and not use my direct PDF link - it is entitled "A New Type of Furniture ESD and Its Implications" by Douglas C. Smith, from 1993
- valbaca 3y agomuch appreciated!
- sitharus 3y agoThis actually happened to one of my colleagues a few years back! Except it was someone in the next row over sitting down causing his monitor to turn off. Took them ages to figure it out.
- fomine3 3y agoExact same case happens for me except my chair doesn't have gas lift. It's weird.
