I have this laptop:
Manjaro installs perfectly from a bootable USB stick but I was not able to use the Asus PB287Q 4K monitor which is connected via display port.
I went ahead and installed Manjaro properly (no USB boot) to see if my Nvidia K2000m would be recognized but unfortunately, it did not.
I googled for solutions and wasn't able to implement a fix.
Then I replaced Manjaro with LinuxMint which instantly (live USB boot) recognized the external display without any additional configuration.
Can someone help me by telling me which commands to run and where and how to paste the output so that the problem can be solved and hopefully be of help to others who have a similar hardware setup.
Overall, if I can get my external display to work, then I am ready to move to Linux because all the software I use on W10 is already open source so it makes a lot of sense to switch.
