Troubleshooting DPI settings on 4K UHD Displays

SMART recommends a DPI scaling factor of 125% for 4K UHD displays. If the current DPI settings are suboptimal, you may receive a notification in the top-left corner of the first Notebook page when Notebook starts, asking you to increase the display DPI. If you dismiss the notification five times without action, a dialog box appears. This dialog box gives you the option to learn how to change the DPI or to disable the notification.

More information about changing DPI settings is available here: Increase the size of the screen display for SMART Notebook by adjusting the DPI settings.
