Crysis 2 DirectX 11 error "Frequencies are not supported"

Hello all,

like the title says I have a problem with Crysis 2.
I installed the high textures and the dx11 pack. As I started the game my screen went black and I saw a blue box on my screen saying: "Frequencies are not supported".
I only can window the game and then I can see the game normaly. I can't play the game in full screen when I enabled dx 11.

I need some help! Please.

Try setting the refresh rate of the game a little lower. Maybe 60Hz.
