Do you ever move your Chromebook place to place with a variety of display / monitor arrangements? I do. So I wanted a shortcut to the Display settings.
chrome://os-settings/display?search=display
This probably won’t work in your browser as a link from this page. Just copy this link and paste it into your browser or create a bookmarks bar shortcut.

I leave the Name blank so there will be just a gear icon with no text in the bookmarks bar.
You can also use:
chrome://os-settings/display
Whatever is faster or easier for you.
