Dell XPS 13 9350 Buzzing Display

Hi,

I have noticed that whenever the (non-touch) screen on my Dell XPS 13 9350 refreshes (e.g. with the mouse pointer moving, webpage scrolling, etc.) I hear a buzzing sound from the bottom left of the display.

Uninstalling the Intel display driver and using the Microsoft Windows generic display driver stops this buzzing from occurring, but that also stops the screen brightness hotkeys from working so it's not really a solution.

Does anyone know how to resolve?

Thanks
