I too have this one. It is a great monitor, but mine has some coil whine unfortunately. And the coil whine is more noticeable when running the monitor at 120Hz. Before getting the U40 I tried 2x U2725QE but both had coil whine that was absolutely unbearable. Either I’ve been very unlucky or the 25 series monitors just all suffer from the same issue.

I have this, extremely satisfied with the picture, size, look and connectivity. Only thing that really lets it down are the speakers are weirdly quiet in a lot of frequencies, wont matter for a lot of people but it's more annoying because everything else about it is great.

Hah! I just ordered that today. ~$2200. Going to use it with a new Mac Studio.
