Linux is the only operating system that supports diagonal screen mode – Linux

Linux developer, xssfox, based in Melbourne, took advantage of this feature to support diagonal computing because he believes the optimal rotation for software development is 22 degrees.

Computer enthusiasts often have specific preferences for their monitor settings. Some prefer large, curved displays, while others opt for flat displays with square aspect ratios. Using multiple screens is also common among power users. However, for those with an ultra-wide screen who find the horizontal or vertical options too limited, xssfox offers the solution. He used the adjustable monitor stand and Linux's xrandr tool (which resizes and rotates) to check the ideal monitor rotation angle for software development.

xssfox has developed a systematic way to evaluate different screen cycles. He started with the traditional horizontal and vertical modes, then used xrandr to experiment with other rotations, like a slightly weird 1° rotation and a mysterious 45° rotation. The tests produced mixed results of questionable reliability, prompting him to continue his search for the perfect solution.

Eventually, xssfox discovered that a 22 degree tilt to the left was the optimal turn. This angle provided the most efficient workspace on the 32:9 Dell monitor. On the website where He analyzes his testsstates: “I believe this is the best screen orientation for software development. It provides the longest line lengths, eliminating concerns about the 80-column limit.”

For those with a screen with the same aspect ratio, a 22-degree angle can also be effective. However, for those who have different requirements for screen rotation, xssfox has built a JavaScript calculator that can be used to generate an xrandr command for specific inputs. For example, owners of the perfectly square LG DualUp 28MQ780 may be interested in “Diamond Mode.”

It's worth noting that Windows users with AMD and Nvidia drivers, as well as MacOS users, are currently limited to rotating the screen in 90-degree increments.
