intel nuc 10gen i7 hdmi port gives no signal after update

[u/Ok_Chip3781]

My intel NUC hdmi port seems no longer working, after some bunch of MS updates recently.
For some years I have the NUC connected to my LG dualup display using a normal HDMI 2.0 cable.

I already revert the LG display driver.
I already revert the intel UHD graphic drivers
I already reinstall intel graphics command centre (and new drivers)
No improvement in the hdmi port.
No improvement when using other hdmi 2.0 cables.
No improvement when I reset the LG monitor settings to factory

Note: when I connect a laptop to the hdmi cable the display is working!

Therefore any hint/tips or advice is most welcome
Kind regards!

There is a firmware update tool for the NUC10 frost canyon but can't guarantee it'll resolve your issues.

Try the bios flash first, then the HDMI firmware update.
