Full screen mode with different screen solution

In the standard player options the graphic mode for full screen playback can be set. When switching the screen solution Windows only accepts a fixed refresh rate or none at all. Because we cannot know your graphic card/screen combination, we refrained from setting a refresh rate. We did this to make sure your screen is not at risk. Windows switches automatically to a possible mode, which you can change (Control Panel / Display / Settings).

This warning is only important if you work with a changed full screen mode. The problem does not exist in window mode.
