Change window resolution at runtime

Hi

I have to change the window resolution at runtime. To be precise, the game will be started and has to read the resolution from my own config file. After that it has to initialize the screen resolution and windowed/fullscreen mode accordingly. No initial config dialog in the beginning is tolerated.

I found the option to "disable resolution dialog" in the "player serttings". But I haven't found a way to change resolution and windowed mode at runtime. I can not use the player settings, as I have to read my own config file. May be that is because the display is already initialized when the game object and the attached script is loaded.

Is there a way to intercept the display initialization, in a very early state of game startup? If not, what could be a work around to perfom such a task? Maybe there is a secret command line option?

Thanks for your help
