BenQ Zowie XL2540 and XL2546

[Maxe]

Update: I've been using the benq zowie xl2540 for the last week and love it. While testing the blur reduction, I decided it was not as necessary as I first thought.

I have a small problem that may require me to return the monitor, though. It makes a whine whenever it is at 144hz and above, 120hz is near enough silent. This is at factory settings and after I change the colours etc. I've tried creating 239hz resolution etc without any success. Is there any way I can fix this? or should I return it?

I got the XL2546 yesterday, it has the same thing... whine above 144hz. In the process of returning it.
