Windows 10 build 14393.726 then rolled out to the Release Preview Ring yesterday, but there was no word on what was included in the fixes.
Thanks to the Update Catalog, we can confirm that Microsoft has resolved the monitor problem. KB3216755 is now available to download manually for users that need it. There's no word on when it will roll out via the usual update method.

It's hard to say why Microsoft hasn't pushed this out via the usual update method, but it might have something to do with stability. The last thing the company wants after a botched update is to cause further problems. No doubt this patch will be tested thoroughly and come with the next cumulative update.
