A: The best way is that you choose the right output format by the player's name. The resolution has been preset to fit the player's screen.  And you also can customize the resolution if you can not find the type of your player in the profile list. In the Setting window, you can select the right resolution for your player. If there is no resolution which fits your player's screen, you can even type a resolution in the Resolution field.
There is a way to adjust the aspect ratios: in the Crop panel, there are these options as 16:9, 4:3, Keep Original, Full Screen, Letter box and Pan&Scan.
