# DPI Per Monitor Awareness

_Written November 2019_

"Dpi Per Monitor awareness" was introduced in Windows 8 so that developers could take advantage of display characteristics that only make sense on high-resolution monitors. The **-dpm** switch in A-Shell implements this Windows function, and you must be running Windows 8.1 or greater to realize its benefits. Below are two examples showing how a monitor with resolution 3840x2160 displays text and graphics with the -dpm option being set (above and left), and without it. On a 1920x1200 monitor, there was no apparent difference between the "with" and "without" **-dpm** setting.
