In a window manager or KDE(x11) you can use nvidia-settings you can click advanced in monitor settings and selected viewport in and viewport out. If you set the viewport out to be the actual resolution and the viewport in to be some multiple of the actual resolution you can get fractional scaling and if you make the factor chosen a function of the relative DPI of your respective monitors you can make things perceptibly the same size across monitors. That's right fractional scaling AND mixed DPI!
You can achieve the same thing with xrandr --scale and its easier to automate happening at login.
You can also achieve pretty good fractional scaling in Cinnamon (x11) directly via its configuration. You enable fractional scaling on the right tab and suddenly global scale is replaced with a per monitor scale. Super user friendly.
Also your copy of Windows was just as free your computer was. You paid someone to configure windows acceptably for you and Microsoft and various OEMs who make windows hardware split your money giving you something usable in return.
You then decided that you wanted Linux on it and now you are the OEM which means you get to puzzle out integration and configuration issues including choosing a DE that supports the features you desire and configuring it to do what you want it to do.
