Kernel > 4.2 TV refresh rate help
Hey,
I have a problem with my TV plasma connected to intel onboard graphics card which uses i915 driver on kernel version above 4.2. My second monitor is working as expected, but TV plasma is showing black screen in boot mode and in graphic mode. The problem seems to be in refresh rate settings for plasma TV. Setting the refresh rate to 24Hz on Full HD resolution with xrandr seams to correct the problem in graphical mode. I want to use 60Hz refresh rate on Full HD resolution. On kernel version 4.2 everything is working as expected but when I try to update kernel and use any version above 4.2 the probem appers.
I'm using vfio kernel from arch AUR if that makes any difference.
Here is my xrandr output with kernel 4.5.1-1:
Code:

Write now I'm using 1920x1080i resoulution with 60Hz but this resolution gives me flickering image.
Any help is appreciated |
