xrandr hdmi3

Hi,

xrandr until today displayed HDMI3 on a list as disconnected. When I plugged a monitor it changed a state to connected and I could configure it with xrandr as I wanted.

After I restarted my laptop today I can't see HDMI3 anymore in xrandr. Plugging in/out HDMI3 cable changes nothing (but monitor blinks for a sec so it is somehow visible by laptop)
Second monitor connected as DP1 works fine.

Macbook Pro 15' - ArchLinux - 4.1.6-1-ARCH #1 SMP PREEMPT Mon Aug 17 08:52:28 CEST 2015 x86_64 GNU/Linux

HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)

Could you help me what can be wrong?
Can I provide any useful information to debug this issue?

Thanks,
Kris
