Text and other items look too large or too small on a DisplayLink screen

When you use a Windows 8-based or Windows 8.1-based computer that has a display that features many dots per inch (that is, a high-DPI display), some desktop applications may appear larger or smaller when you move them on to a DisplayLink screen. This is due to Windows using the same scaling on all screens. 

This is a general problem with Windows 8 and not specific to DisplayLink displays. There are a number of articles on the internet which describe the issue and offer workaround for the issue. For example:

How to Make the Windows Desktop Work Well on High-DPI Displays and Fix Blurry Fonts
How do I fix desktop app display issues?

This behaviour has been improved on Windows 10 and there is a good description on scaling and the problems it addresses here:
