Very valuable feedback, thank you. Coil whine would drive me bananas. Username checks out.

To be noted that EPD displays are in general completely silent. This exception...

Of course, there's more to a monitor than just the display. It could be the power supply, driver board, etc. that's the cause for coil whine. I've had it on one laptop that I owned; whenever there was I/O with the SSD I'd get a little bit of whine.
