Resolution Selection
Set the application's output resolution with the following flag:
-windowsize <xres> <yres>
This is the window size of the application.
Set the screen resolution with:
-screensize <xres> <yres>
Use this option to set the screen size when there is no window system running, as is the case for egldevice. When a window system like X11 or Weston is running, the screen size is already set, and this option is ignored.
To specify a desktop offset, use the flag:
-windowoffset <xoffset> <yoffset>
