Flickering when using maximum resolution

Hi guys,

I just installed ArchLinux on my laptop and I have an issue with my graphical driver.
I have notice this behavior also during the installation process but I thought will be fixing at the end.

The configuration of my laptop is an Intel HD 620 graphical card with an I7 8th Gen.

The issue is that. If I set the maximum resolution the monitor start to flickering almost every 2-3 minutes.
If I connect an external monitor by HDMI and I set it at the higher resolution, basically it's impossible to use it because it's continue to flickering (both external monitor and laptop`s monitor).

I already tried to use a kernel parameter as from Wiki`s page of Intel Graphics but it doesn't working.
For the drivers I just follow the Wiki documentation.

Maybe is worth to specify that I'm using Xfce.

I forgot to insert this error which I got from dmesg:

[   46.002722] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun
[   46.004034] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

LE: I found the solution after almost 48 hours of investigation.

For this kernel version

Linux archlaptop 5.2.14-arch2-1-ARCH #1 SMP PREEMPT Thu Sep 12 10:42:38 UTC 2019 x86_64 GNU/Linux

I added the following kernel parameters:

GRUB_CMDLINE_LINUX_DEFAULT=".... quiet splash intel_idle.max_cstate=4 i915.enable_psr=0 i915.enable_dc=0 i915.enable_fbc=0 i915.enable_dp_mst=0"
