Xbox 360 to desktop monitor via HDMI help

[Wrbs2000]

I've hooked up my PC monitor to my Xbox 360 via a HDMI cable. Both my Xbox and monitor have an HDMI input, and when I turn on my Xbox and my monitor it goes to HDMI and says no signal. Please help me!

Do other monitors/tvs work with it?

Have you used that cable before, have you connected that display to other devices with that hdmi connection and again as he mentioned above have you tried other displays?
