PLEASE HELP - BLACK SCREEN

[Noxris]

I started the game and it was working properly, so i went to change the screen resolution to my TV screens resolution (1768 x 992) and it turned to a black screen. every time i open the game, black screen. i cannot play at all. i tried changing the settings with the black screen, but nothing worked, i have reinstalled it, and restarted my computer, and its still a black screen. (BTW i have a gaming PC so its not because my computer cant handle it)
