just bought NUC8i7HVK few days, connect with 6 monitors/ less, problem is when connect any screen via mini hdmi port at the back, when leave the monitor turnoff via control panel win10 pro, the system is freeze, need to hold & push power button to shutdown and restart.
while using the system, there is no any problem / symptom, if leave the desk and monitors shut down it shall FREEZE!!!
