Ever since version 17.10.1 I will lose my monitor signal periodically. Before that happens, my cursor hangs/lags as if the system was under heavy load. Then I get a black screen and the "no signal" message. This starts during driver installation (not the black screen cupled with the remove device sound). After 2-3 incidents, the system runs fine for a while. When I start any game, it occurs again eventually. When I install the 17.7.2 driver, everything runs fine.
CPU: Ryzen 5 1600
GPU: PowerColor RX 480 Red Devil
Board: Asus ROG STRIX B350-F Gaming / Bios 3401
RAM: G.Skill Ripjaws V 2x8GB DDR4
Monitor: Acer XZ271 144Hz FreeSync / Connected via DisplayPort
OS: Windows 10 64bit 1709
What I tried:
-DDU and try any newer version including 17.10.x, 17.11.x, 17.12.1,18.1.1
-do a fresh install of Windows 10 1703 and 1709
-setting manual p-state voltages in BIOS
-increase power target
-lowering core clock
-tried different DisplayPort cables
-changing refresh rate in Windows to lower values
Only version 17.7.2 (or maybe lower) runs fine.
I observed that switching from DisplayPort 1.2 setting to DisplayPort 1.1 in my monitor OSD, will cause the periodic "No signal"/black screens again.
Since I have a way to reproduce this on my system, I logged the temps/voltages/clocks during the issue into a file. Nothing suspicious there. All values were in their expected range. So I doubt it has something to do with power control.
So I'm pretty sure now that this is somehow related to the DisplayPort.
