Will I be able to connect the following to the LED Cinema Display?

Hey

I know the display only takes the miniDisplayPort format, and I wanna know if i can somehow get my xbox 360 using it.
So is there anything that i cant get that will connect the HDMI cable from the Xbox with the miniDisplayPort cable, and not loose any sound etc.

Chears

No way to do it and retain sound.
