NUC NUC7JY: hdmi primary output changing after each restart

[CompuMat]

Hello,

I am using Linux (Ubuntu) on the Intel NUC (BOXNUC7CJYHN2). This NUC provides 2 hdmi ports. After each restart I have to plug the screen to the other hdmi-port, to see the Linux screen. BIOS screen is visible on both ports all the time. Means:

Starting the system, after having Linux up and I migh not see the screen, I have to move screen-hdmi-plug from one hdmi port and plug it into the other port. When then restarting, after Linux is up and running again, the screen is black and I have to plug screen to the other hdmi-port.

The start screen always appears on both ports.

How can I fix the output to one port? Or am I able to disable one hdmi-port in BIOS? How?

Thanks
