I have a 2016 MacBook Pro w/TouchBar, these have the AMD Radeon Pro 450. I'm running the latest driver. Either that's 21.19.128.7 or it's 17.12.2 depending on who you ask (former is device manager and latter is AMD driver install).

 

I'm running Windows 10 Creator's Edition with the latest updates on a bootcamp partition..

 

I got a new BENQ XL2730 monitor and I have spoken with them at length about this issue. They seem to believe the problem is the AMD drivers in Windows 10.

 

The problem ONLY occurs in Windows, the problem does not occur at all with Mac OS High Sierra.

 

The problem is worse (more annoying) with a display port adapter/connector and slightly better (less annoying) with an HDMI adapter. They both have the same issue:

 

Once Windows reaches the login prompt to type the password, the signal cuts out shortly thereafter. It does not return until I unplug the monitor repeatedly and plug it back in with the laptop clamshell open. This is so obviously either an AMD Windows driver issue or a problem with Windows itself. I'm running the AMD Radeon driver FROM AMD, not Apple. The Apple one won't even work anyway, it's obnoxiously outdated.

 

Windows 10 Version 10.0.16299.248
