Hi everyone,
I already spent days on this problem, trying out everything I could find on different forums.
Any help will be greatly appreciated and I will be happy to provide any more information necessary.
Using Ubuntu 18.04, Nvidia drivers 440 (or any other version), the HDMI display is not detected. The hardware itself works as I have a dual boot with Windows that works in this configuration I am sure it is something small in the configuration that I am missing.
