To run CrossFTP on a a high-DPI display (e.g., 4K), sometimes you may find its UI is too small. To solve this issue:

On windows 10:

1. Find java.exe you installed.
2. Right click -> Properties
3. Go to Compatibility tab
4. Check Override high DPI scaling behavior.
5. Choose System for Scaling performed by:

On Linux:
You can add parameters to the java binary which launches the CrossFTP, you can use the option -D to pass a value for the sun.java2d.uiScale proprty to specify a scaling factor for Java2D. This will scale your application. The scaling factor value is a double. Make sure that you pass this option to the java binary itself, not the launched Java application.
Example: Launch crossftp.jar with a UI scaling factor of 2.5

java -Dsun.java2d.uiScale=2.5 -jar ...
