dmesg

I have connected 2x hdmi full hd + 2560x1440 + 1x DP full hd.
on display with 2560x1440 resolution I constantly get black screens and
horizontal strips over the screen. I am sure now that its not problem of cable
because I tested it on my external GPU and recently I get black screen on other
monitors from time to time but not so often as on 1440p monitor. I also tested
windows, it doesnt gets black screens.
This also happens in TTY.
Also, don't know if its luck or not, but when I connected only one monitor,
1440p over DP, I didn't get this problem.  

This is video how it looks like: <a href="https://www.youtube.com/watch?v=fB2pJsD9NFQ">https://www.youtube.com/watch?v=fB2pJsD9NFQ</a></pre>
