I have the free current version of NoMachine for Linux (had the paid license for years, but now retired).  I connect from Chromebook running Linux with NoMachine client installed to my remote Debian/Linux server also running exact same NoMachine package on the server side.  I can change display settings each time, and get what I want.  However, I should be able to SAVE these settings and reconnect thereafter without having to save the display settings.  But, I cannot seem to figure out how to save the settings.  It is becoming a nuisance to set the display each time.  Anyone know how to do this?
