[QUOTE="mafocari, post: 1901004, member: 407922"] The room is simply a second bedroom, not a home office; I'm just using it for work. That's completely irrelevant anyway, any room could be miswired whether it was intended as a home office or not. I swapped out the adapter for a USB-C to DVI cable, and while touching the table with some discharge causes the monitor to blink once or a few times, it doesn't shut off or screw up the display anymore. So the adapter seemed to have caught the discharge and send most of it straight to the monitor in some way that jerked around with it. The new cable seems to be better with it, or at least not send chaos to the monitor. My bet is the adapter will work just fine in any other situation, though I don't know when I'll ever use it again. I hate wasting money on an adapter like that. I'd think about bigger solutions if I can't just blame it on the cable/adapter to the monitor, but the fact remains that the MacBook or its port could still be to blame. I don't know how to troubleshoot that, but I got the same behavior from the front port as from the back port. I could try swapping the cable from right to left, but that's inconvenient and awkward, and really, it'd be nice to know if anyone else has had weird electrical issues like this with MacBook or its ports. The whole MacBook surface is metal (lid is closed), so who knows why only the monitors connected to these ports or their cables are having static discharge issues... if there's some way to troubleshoot the MacBook or its ports in relation to electrical output, I'd love to test that, but I'm not sure how. Have you ever had issues like this, or tried testing the ports? That's what I'm curious about now. I'm not an Apple fanboy enough to think that the problem couldn't be with the MacBook 2019's design.
