Hi @samothx, thanks for your reply, for us is the same, if the HDMI cable is connected when the device powers up, we can plug/unplug any number of times and is going to work. When is not working is when the device powers up and nothing is connected in the HDMI port. Our question comes because we could fix it using RESIN_HOST_CONFIG_hdmi_force_hotplug =1 in a Raspberry Pi 3B+, but not for Intel NUC
