S2716DG, buzzing issue, resolved?

I've had the S2716DG for a few months now and there has always been an audible buzz... after further research on Google I found out that you can make it go away by raising the brightness to 91% and then bringing back down, but only to have it happen again when the monitor wakes up from sleep (not deep sleep, since that is a totally different can of worms). I've seen some posts here, other online forums, and reddit regarding this issue, but it sounds like no one with the issue ever reported back having had the issue resolved. I actually contacted Dell and received a replacement refurbished unit a few days ago. I was pleasantly surprised that the replacement came so quickly, but unfortunately it also had the same exact buzzing issue. I contacted Dell again and they told me that they would send out another unit once I return the replacement, but my fear is that the next one is going to have the same issue as well. So my question is, is everyone just "dealing with" the buzzing by adjusting the brightness every time you power on your computer? Or has anyone successfully received a unit with this issue fixed? Just for reference my unit is a revision A04, built in December 2016. The first replacement I received was also a rev A04.
