My new Corebook Pro X won’t display an image on my LG Ultrafine 4K monitor over USB-C. I’ve never had an issue with Windows laptops and the monitor.
Have downloaded all Windows Updates & tried Intel’s own display driver. Have tried various USB-C cables.
Any ideas? I have tried with the charger both connected and disconnected. The monitor makes a noise as if to say that it is connected, but the screen remains blank and I get the usual ‘Windows does not recognise this USB-C device’ error.
Do you enabled the USB C Feature via the BIOS?
Hi @corebook did you find a solution? I’m in the same situation.
Can’t push Corebook X beyond HDMI resolution on an external monitor that supports 3440 x 1440.
Maybe I found something… Intel Iris Plus Graphics 655 video card, which my Corebook X is equipped with, seems to support up to 3840 x 2160 @60, via DisplayPort 1.2/e DP 1.3Hz.
I’ll check this out in the next days…

if you find finally some help please let us know.
OK, just want to share with you that I’m now having one external display connected at a very nice screen resolution of 3440 x 1440 directly via a USB Type-C - HDMI fast cable (brand UNI, which can be bought on Amazon).
This is exactly what I were trying to do and it was easier that I thought.
I didn’t try to connect the screen via DP cable or adapter, as I was planning to do, because I later read in this forum that Corebook X doesn’t support DP Alt Mode.
The cable I’m using passes audio signal too, and the my external monitor speakers quality is quite better than the CBX one 
.
I am glad that finally it worked out in the end
