The high contrast setting in Microsoft Windows heightens the color contrast of some text and images on your computer screen, making those items more distinct and easier to identify. You’ll find this setting on the Ease of Access page in Windows 10, Windows 8, and Windows 7.
If you’re using the high contrast setting in Microsoft Windows, you should also select Enable high contrast in your Microsoft Dynamics 365 personal options. On your dashboard, click or tap > Options. Click or tap the General tab, click or tap Enable high contrast, and then click or tap OK.
