Acer laptop and external monitor wakeup...

Hi I have Acer VN7 592g with external monitor connected with HDMI (does't wakeup after suspend in ~5 min)
I tried googling and fix this issue, but no success

Sysinfo:

Kernel: x86_64 Linux 4.10.9-1-ARCH
Shell: zsh WM: i3
CPU: Intel Core i7-6700HQ
GPU: Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2) + inactive NVIDIA 960m

ISSUE:
after some time, laptop go to suspend mode, then after exit from suspend external monitor does't wakeup (hdmi connected, I can move mouse to this monitor)
When I wake-up laptop in 1-2 min, monitor wakeup correctly (tested with xset s 10 10). After 5 min monitor does't wakeup

I tried, nothing helped:
disable discrete card (acpi/call)
various kernel boot params (backlight, acpi = win 2009, etc)
use xrandr to wakeup (`xrandr --auto,  xrandr --output $SCREEN_2 --auto`)
use TV with hdmi - same situation
`xset edpms force standby`


I found only one suitable "error" in log files:

acer_wmi: Unknown function number - 6 - 1 in log files issue

journatctl -n 300

Does it can be kernel or Intel Drivers Issue?
