    17.11.x - 18.1.1 "No signal" and black screen


      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

      No overclocking.


      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

      -CMOS reset

      -setting manual p-state voltages in BIOS

      -increase power target

      -lowering core clock

      -tried different DisplayPort cables

      -disable FreeSync

      -changing refresh rate in Windows to lower values


      Only version 17.7.2 (or maybe lower) runs fine.


      UPDATE (21.01.2018):

      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.
