I've got display problem. Horizontal stripes appear sometimes (randomly?) on movies or just desktop and stop when I change screen resolution to other and switch back to 1080p. It only happens with my iiyama xb2472hd via hdmi. Everything is fine using Windows. I've tried other monitor via hdmi and the problem doesn't occur.
Any ideas how to find source of problem?
Here is video:
Iiyama XB2472HD + Lenovo y580 which is using Intel HD Graphics 4000 as display device
I've got the same problem. Any ideas of what it might be?
After months of having this problem I realized that it occurs only with that monitor (Iiyama XB2472HD but probably others too) when I turn it off and than on (after some time) while Arch is still running...
Common situation: I lock the screen in KDE than turn off the display using capacitive button on the device. When I come back after few hours and turn it on the stripes appear. Switching to other screen resolution for a while makes it fix.
Could it be some synchronization problem or something like that?
Have someone any idea how to debug it ?
I believe that someone (kernel developers or Iiyama) made some bad assumptions while implementing HDMI standard...
