Incorrect character size

Many Mediaportal users complain about the size of characters inside Mediaportal.

This is not a Mediaportal issue. This problem is usually caused by improper screen DPI settings. The DPI value for custom text size must be of 100%. 

Using Windows 7 or Windows Vista, open the Start menu and click on the search box. Type "DpiScaling" and press Enter.

Make sure the selected radio button is "Smaller - 100% (default)" and click on the "Apply" button.

Click on "Log off now" and the new dpi setting will take place.

At last, you have to delete the Mediaportal cache folder before starting Mediaportal following this page: ReCaching.
