I have my computer connected to 3840×1200 monitor. In the past I could connect with nomachine and the slider on the configuration allowed me to change the resolution to 1920×1080, this was using Manjaro Linux with Cinnamon desktop enviroment. But I recently had to reinstall everything and choose to install Manjaro Linux with KDE , now when I connect with NoMachine I get no option to change the resolution, it is fixed to 3840×1200.
Any idea what I’m doing wrong and how can I solve this?
