That is some top tier investigating and persistence, hats off. I would've used the excuse the upgrade the monitor lol.

Or replace the 30-cent capacitor that's likely causing it.

It's likely one of the power bond wires from the glass screen to the silicon IC. Without equipment stretching into the millions of dollars, you won't be fixing that.

Why would that cause a current-dependent symptom? Do they rely on a lot of parallel bond wires? If so, breaking one isn't realistically going to do anything.
