Lex got a new Lenovo laptop and can't get everything to be readable in Windows. Leo says that Windows 10 has a scaling setting that will enable you to set the resolution to how you like. Part of the problem is that laptop screens have gotten too high in resolution, making text tough to read, quite ironically, because the letters are too small. So you tend to want to use about 100 dpi for text, or half resolution, and then 200dpi for video playback and photography.
There is a setting in Windows that can automatically switch the scale, but some apps, like Quicken, can ignore that. Here's a technote about it - https://www.quicken.com/support/work-around-display-issues-high-resolution-monitors
