Dell monitors affected by EMI spike from gas lifted chairs

Posted 08 January 2020 - 10:02 AM

It's not your gremlins or house ghosts.. it's your butt in your chair causing monitors to tweak out! Them cables are not to be over looked folk!


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.
