Ferrite chokes easily fix this problem. Very useful to have a box of them in an office full of people.

It’s pretty clear that most modern standards (HDMI, DisplayPort, thunderbolt, etc) are so close to their physical limits that there’s no more room for errors.

I'm having the same problem, except it's crashing my dang PC. Actually, it's only crashing the GPU, but that's pretty indistinguishable from the whole PC crashing in practice.

Now I'm wondering if I should ground my chair to the shelf my PC is sitting on.

As pretty obvious evidence this is static related, it only happens in the winter.

Remember the "degauss" button? I had no idea what it did, but the sound it made sure was satisfying. https://youtube.com/shorts/R0OhD2Bc6FY

That attempted to demagnetize the components in the CRT that could cause beam deflection and warped colors.

That "component" was the shadow mask: https://en.wikipedia.org/wiki/Shadow_mask.

I have the exact same problem, except it affects my cheapo keyboard. Almost every time I move from my desk, the Num/Caps/Scroll Lock LEDs flash up as the controller restarts. And since it's a PS/2 model, if I'm holding a key and let it go as I'm standing up, it never sends the termination sequence and keeps typing it until I press it again.

I'll definitely try some of the tricks from this article.

Might want to increase humidity. In ESD rooms the humidity is controlled and kept high to reduce static build up.

to add:

> In my particular case, my chair wheels are made out of plastic (non-conductive), so my solution was to “ground” my chair by adding a metallic chain from the chair to my room floor. I got the idea from reddit.

The chain grounded chair is used all the time in ESD rooms. The floors in these rooms use semi-conductive flooring which is tied to a ground rod. The chair is grounded to the floor which is in turn ground bonded to earth.

This. I had a huge problem with static shocking my desk in the dry winter air, causing my monitor to blank out for a few seconds. A small, quiet ultrasonic humidifier completely eliminated the problem.

On a side note, distilled water is highly recommended with ultrasonic humidifiers. Heat-based devices evaporate solely the water and leave mineral deposits behind. Ultrasonics create tiny droplets _along with the dissolved minerals_. Hard tap water or mineralized drinking water will coat your work area in chalk-like dust.
