I generally calibrate per filament brand and type. Sometimes different colours of the same brand/type behave differently, but usually it's fine. Haven't really had issues where I had to change settings between batches.
Make sure you do the calibration on filament you're sure is dry however.. Then, in case you run into issues later just make sure it's dry first.
I can't believe how many of my print issues were simply related to wet filament.
Seems like flowrate is too high and/or your filament isn't dry (or maybe a partial nozzle clog). I know you said it's 'fresh', but unfortunately just because it's sealed doesn't mean it's dry.
For windows users, check out Twinkle Tray! Tray icon with sliders for brightness and contrast for all connected monitors, as well as power buttons. May have support for keyboard shortcuts too, not sure.
You can use a usb ir receiver, I can recommend FLIRC.
