We have a Samsung 4K 28" UE590 display that's connected to a Macbook Pro 13" 2016 with an Apple USB-C to HDMI multiport adaptor. The whole setup is on a glass table.

We're getting huge amounts of static that interferes with the image on the display. When using the same setup on a normal wooden table, it works fine.

Except selling the glass table, what can be tried to avoid the static electricity problem?

thanks for the help

  • Try wrapping the cables in aluminum foil to shield it. If you have anti-static bags, you can try wrapping them in that. – Allan Feb 17 '20 at 21:41
  • You could also try an anti-static mat to put all the equipment on – Allan Feb 18 '20 at 1:32
  • Sounds like some kind of grounding problem. Have you tried swapping out the USB and HDMI cables. When you put it on the wooden table do you use different electric outlets? – root Feb 18 '20 at 8:46
  • @root - Why would it be a grounding problem if it exists on a glass table and not on a wood one? Both materials are insulators, but glass can develop a static charge. – Allan Feb 18 '20 at 20:16
  • Tks to all for comments. I will try the anti-static mat as that seems to be the most logical thing to do. thanks allan. – MarkD Feb 19 '20 at 15:07
