Most people ignore this productivity-enhancing monitor setting - here's why you shouldn't

"Turning a computer monitor from a landscape position to a portrait position may seem odd at first. After all, a horizontal display allows you to see more content on-screen, plus it is a more familiar experience. However, there are certain situations where flipping your screen vertically is genuinely useful. Programmers, for example, often prefer this orientation because it lets them see more lines of code without needing to scroll. Writers, like myself, appreciate this mode, as it makes reading and creating documents easier."

"Vertical monitors can also free up physical desk space and help with multitasking. You can position web pages and apps, such as Slack, on top of each other to improve readability. I've seen comments online claiming that a portrait-aligned screen is ergonomically better. That might be true in some scenarios, although there is a size limit. I'll get into it later, but first, let's go over how to rotate your monitor."

"The simplest way to rotate your monitor in Windows 11 is through the Settings menu. Launch Settings > System > Display > Scale & layout > click the Display orientation drop-down menu. By default, it's set to Landscape, but you can choose Portrait to flip the screen 90 degrees to the left. There are also Landscape (flipped) and Portrait (flipped) options. The former turns the screen upside down while the latter flips the screen 90 degrees to the right."

Vertical monitor orientation increases vertical visible content, allowing programmers to see more lines of code and writers to read and edit documents with less scrolling. Portrait alignment can free up desk space and aid multitasking by stacking web pages and apps for improved readability. Some users report ergonomic benefits depending on screen size and use case, though very large displays may limit advantages. Windows 11 supports screen rotation through Settings > System > Display > Scale & layout > Display orientation, offering Landscape, Portrait, and flipped variants. Third-party utilities can add keyboard shortcuts and additional convenience for rotating displays.
