NUC8i7HVK default startup monitor

[I_]

Hello

I have the NUC8i7HVK with 32GB of RAM and 512GB NVMe storage. It has a startup/user password set through the BIOS which needs to be entered before it will boot the operating system (reason for mentioning this explained below).

I have been using it without any issues for months with an LG 25UM58 monitor connected via the HDMI port on the back.

The older one is starting to lose its colour so I recently purchased an additional LG 25UM58 and connected it via a mini display port to HDMI cable. This is now my primary monitor facing directly in front of me.

When booting the system up, the password prompt always shows on the old LG monitor. I have even tried switching the cable around (switching it off, connecting it via mini display port, turning it back on etc) with no avail. The old monitor seems to always show the BIOS password and pre-operating system information.

If I disconnect the old monitor then the password prompt shows on the new monitor. I need accurate colours for my primary display and because of limited desk space and the way I sit, I cannot physically swap the monitors positions.

Does anyone know why this is happening and what I can do to fix this?

The ports are scanned for monitor presence and the first one identified is used for BIOS I/O. Here are pictures that detail the detection order:

Now, I realize that you said that you tried swapping cables. That should have worked. Try it again, but this time power off between switching.

You marked a best answer so I cannot respond - but I can edit!

Here are answers to your questions (which appear below this response):

1. Yes, the only way to power off is to remove power completely.
2. The HV NUC has two Ethernet solutions. The first, which I presume should be primary, utilizes the MAC built into the chipset (PCH) and a i219-LM PHY. The second, which I presume to be the secondary, utilizes a i210-AT controller (which contains both MAC and PHY). Using the diagram above (and my presumption of which is the primary solution), the left-most Ethernet connector is the primary and the right-most Ethernet connector is the secondary.

Thank you. I did turn power off the device but Intel support told me to remove the power completely which worked (not sure if that's what you meant). Either way, thank you for the image too, it will be very helpful. I don't suppose you know which LAN port is the primary do you?
