How to Improve Working with Multiple Displays in Outlook

These days, displays are usually capable of high screen resolution, the so-called “High DPI” (dots per inch) displays. However, using multiple monitors can become a problem when you simultaneously use older ones with lower DPI and newer ones. You may experience display issues when moving Outlook and Office apps back and forth.

As a consequence, Outlook introduced a feature to address these issues. You can choose between “best appearance” or “compatibility,” depending on your needs.


  • Optimize for best appearance: This option is selected by default and usually ensures that the appearance is optimized when using multiple screens. However, it works best for the newer “High DPO” displays.
  • Optimize for compatibility: If you are using both older and newer desktops with different ” DPI ” levels and experiencing display issues, this mode will disable dynamic scaling for the current application. However, text might get slightly blurry as a result.

How to Change Settings for Working with Multiple Displays

 Step 1: Select “File” at the top ribbon.

Step 2: Go to “Options” on the bottom left.

Step 3: In the “General” section, tick the box next to the preferred option, “Optimize for best appearance” or “Optimize for compatibility.”
