Poor resolution optimization

Sorry for my English, I used the google translator a lot uwu.
I use a laptop with a 2k screen, and I have a problem with the options of the "monitors" app, because in the option of low pixels per inch the desktop environment becomes tiny with respect to my monitor, and in the option of "duplicate pixel" the lower parts of the windows are cut off (this only happens with the default apps, such as printers, keyboards, monitors, etc.). I don't know how to solve that problem, and I would like to add the option of, for example, a scrollbar, or change the size of the default apps more.
Thanks you for reading this, I love Elementary OS.
