Resolving Monitor Blackouts Caused by Static Electricity and EMI Spikes

I recently faced a peculiar issue where my external 4K monitor, connected to my MacBook Pro, would go black or turn off due to static electricity generated by my Ikea Markus chair. Despite changing clothes and shoes, the problem persisted, causing not only annoying shocks but also disrupting my monitor connection. Upon investigation, I discovered that gas lift office chairs can cause EMI spikes when sitting or standing, affecting video cables and causing the monitor to malfunction.

To tackle this, I identified two main problems: static electricity and EMI spikes. For the static electricity, I grounded my chair by attaching a metallic chain to the floor, which significantly reduced the electrical shocks. For the EMI spikes, I used ferrite rings around my video cables, as recommended by DisplayLink and other users on Reddit. While this didn't completely eliminate the problem, it reduced the frequency of blackouts, especially when standing up slowly.

This experience, supported by references from DisplayLink and community discussions, highlights a common issue among users with similar setups. Although the solutions aren't perfect, they have improved my situation considerably. If you're experiencing similar problems, these methods might help, and I'm open to hearing any other solutions you might have.
