TFT Cinema Display (30-inch) with low resolution

Hi.

I've connected an DVI LCD Cinema HD Display (30-inch) to my laptop running Windows 7.

It has been recognised but the system do not recognize more than 1280x800 as screen resolution when it's connected through DVI or Display Port interfaces.

I'm hardly searching for Windows Drivers (VISTA or 7) but can only find for Windows XP.

Does anyone know where can I get this driver?

Laptop:

• LATITUDE E6440
• INTEL HD Graphics 4600

Display (Apple Cinema Display (20-, 23-, and 30-inch DVI) - Technical Specifications)

• Apple 30-inch HD Cinema (model M9179LL/A)
• Possible resolutions:
  • 2560 x 1600 pixels (optimum resolution)
  • 2048 x 1280
  • 1920 x 1200
  • 1280 x 800
  • 1024 x 640

Thank you in advance.
