BootCamp Windows 7 Macbook pro retina screen note recognized

Hi,

Sorry for my bad english.

I tried to install Windows 7 with Bootcamp.

The only problem for me is that the screen (the graphic card) is not recognized, it turn with drivers for VGA standard graphic card 8bits... it's a shame !

I tried to install NVIDIA drivers, but the graphic card is not found.

Bootcamp utilities don't change anything.

Thanks for your help.
