Noisy Wing compact

Hello, I’m surprised by something on my new Wing compact. At the network RJ45 ports on the back of the console, there is a small, continuous noise that is quite unpleasant. I’ve noticed that it varies depending on the different levels of brightness. But most notably, it changes with the brightness of the screen. I can make it disappear by setting the screen brightness to the minimum, for example."

I’ve heard that some people experience a noise that disappears when connecting a stagebox. Is there a connection? Has this noise been noticed before and is it considered normal? It’s quite annoying for recording close to the console or even in a small theater representation for people near the console.
