+Options can also be passed after the mode, using commas as separator.

+ Sample usage: 720x480,rotate=180 - 720x480 mode, rotated by 180 degrees

+Valid options are::
+
+ - margin_top, margin_bottom, margin_left, margin_right (integer):
+ Number of pixels in the margins, typically to deal with overscan on TVs
+ - reflect_x (boolean): Perform an axial symmetry on the X axis
