To X34(A) Owners, Test your Monitors for Coil Whine Here.

To Acer X34 Predator owners,

Please test your monitors for coil whine on the following web page with your monitors set to 100hz (or as high as they'll overclock) and report your results for coil whine in this thread.

I've read many reports of this monitor experiencing coil whine to some degree on various forums, but would like to know your experiences. Is it just the vocal minority experiencing this? Or are most people getting it and putting up with it?

I am experiencing distracting coil whine on my newly delivered X34A during general web browsing, even with the monitor at only 60hz. At 100hz it is noticeably worse.

Please don't be shy. The more responses we get (good or bad) the better

I would like to add a poll to this thread if I can. How do I do this?

Why would u even be bothered about something u cant hear without sticking ya ear on the monitor? Do u game in complete silence with no sound or something?

And no i cant hear anything on mine and had mine since release date

I didn't have to deliberately look to hear this coil whine - it is audible during normal web usage from a sitting distance of ~4 feet away over the noise of my case fans. It occurs enough for it to be distracting to me during normal use, although it's not really an issue while gaming as it would be drowned out by the noise from my graphics card alone if I had the speakers turned off.

To give an idea of how loud it is, on the test web page I linked in the OP, the coil whine can be heard from outside the room!

Manufacture date on my monitor is March 2016. Responses so far seem to indicate that those with monitors from earlier batches are alright.

Wasn't it an issue above a certain brightness level? Or a below a certain level? Whatever it was it was it was so far out of my level of useability it wasn't an issue. If it was turned it up or down to silly levels you could hear it but in normal use it wasn't an issue I seem to remember.

Mine wasn't affected by brightness levels at all. I read about that as being a potential solution on the Acer forums but it didn't work for me. Mine seemed to be a result of the overclock, but could still be heard at 60hz and even 50hz on some web pages.

V v tiny amount at one particular point, so I'm more than happy with that

V tiny amount whilst running that however it's the first time I've ever heard coil whine from mine and I had to have my ear pretty much on the panel.

You're both very fortunate! Mine could be heard for all but about 4 seconds of 1 cycle of those bars expanding and contracting. Loud enough that I could hear it from outside the room.

All my monitors play the tune with that web site.

What monitors do you have?

I've bought a replacement X34 to go with my 1080. This one still still has some coil whine on the linked website in the OP, but is better than the first panel I had. It also has considerably less back light bleed and has no other problems, so I'm going to be keeping it. Quite happy with it and don't think it's likely I'll get a better panel back if I send this one in for replacement.
