Turn off Office animations
Office 2013 is the first release to use hardware acceleration throughout the user experience to deliver beautiful, fluid animations. But if you use your computer without a display or just prefer to block unnecessary animations, you have the choice to turn them off.
Open the Ease of Access Center (shown below) by pressing the Windows logo key + U.
Under Explore all settings, click Use the computer without a display.
Under Adjust time limits and flashing visuals, click Turn off all unnecessary animations (when possible).
