Using multiple monitors is life-changing as you enter into a whole new world of having at least double the real estate space for your favorite apps. It does, however, come with a fair few issues, one of which is that item sizes frequently break when moving them between monitors so your small File Explorer window may grow to gigantic proportions once you move it to your second monitor. Windows 10 comes with new per-display scaling features which allow you to maintain the item sizes across all monitors or increase/decrease them according to your preferences.
Configuring display scaling
The easiest way to get to the settings we need is to type scaling in your Start menu and either hit the Enter key or click on the first result that appears. Alternatively, press WinKey + I to open the Settings and then head over to System > Display. As you can see, the very first option lets you change the size of text, apps and other items (like menu bars) with a single slider. This slider works on a per-display basis so you will have to set it up on all of your monitors if you want to have specific item sizes for each. Just make sure that you have selected the correct display from the window above.
If you would prefer the items to retain their size across all of your displays, simply enable the same setting for each. This will force Windows 10 to adjust the item’s size though it may sometimes lead to old issues. You can also configure your multi-monitor setup even further using the “Multiple displays” menu found just below. Windows will ask you whether you want to adjust your screens so that they both align with each other, a very useful feature that was unfortunately missing from previous versions of the OS.
