Two different computers with one Microsoft account

Two different computers with one Microsoft account

I recently bought a 13 inch 1920x1080 laptop. If I set the default scaling
to 100% in Control Panel -> Appearance and Personalisation -> Display,
it's too small to be usable. I set it to 125 % and it looks good.
Today I checked my desktop PC with 1680x1050 resolution screens. It has
the same scaling as the laptop though in Control Panel it says it's 100 %.
How do I change it on the desktop PC?
After I noticed this I changed the synchronizing settings and disabled
options to synchronize desktop backgrounds and such. I restarted both PCs
but no effect.
