            Bug ID: 102389
           Summary: Random black screen on RX 470, HDMI 4k-60Hz
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: jeremi.jasinski@gmail.com

I am using amd-staging on arch linux -
https://aur.archlinux.org/packages/linux-amd-staging-git/ and AMD RX 470.

I have 4k monitor (AOC U2879VF), which display port connector has broken, so
i'm forced to use HDMI. On dp there were no problem, unfortunately while using
HDMI 4k 60Hz I get random black screen, lasting for 1-2 seconds, while using my
computer (watching movie, playing games, or browsing internet). 

The black screens happens since at least 4.11 amd-staging-git version.

I attached dmesg log, and xorg log. If you need something else please tell me.

I've changed system to Kde Neon, with stock kernel: 4.10.0-33 and amdgpu-pro
driver, but the problem is persistent.

I'm attaching new dmesg and Xorg log files. I don't know if errors in dmesg are
causing black screens, because they come up at different time then the black
screens. So maybe it's problem with monitor? 

I've also noticed that black screen happened at least once in virtual console.

This problem is really annoying, if you need some other logs, or information
please write, and I'll try to provide it.

Just a thought: The symptom you describe ("random black screen, lasting for 1-2
seconds") can be caused by bad HDMI cables - especially when using 4k / 60Hz
modes - I had experienced that in the past on two occasions.

Have you tried using a different (preferably short, high-quality) cable?

BTW: Only very few HDMI cable vendors guarantee their products to work up to
600MHz clock frequency, which you require for 4k 60Hz.

Thank you for your response. I've tried two different cables, and none of them
fixed the problem. 

I will buy dedicated 4k 60hz cable and see if theres any difference.

I still have this problem, on linux 4.15 on KDE Neon with dc enabled.

So I bought DP to HDMI active converter, which supports 4k 60hz. While using
this converter and the same HDMI cable, blackscreens disappeared. That would
indicate, that the problem is in driver, not in bad cable.
