if it works, it should work automatically. try and see
but, if the handshake protocol of your lcd is not compatible with the xbox 360 it won't work. i have the same problem with my 24 inch full hd samsung monitor, it has dvi. i used a dvi-hdmi converter, and get no signal with my ps3. apparantly in some firmware updates by sony the handshake protocol was updated, after which the monitor does not recognize the ps3 anymore. it still works fine on my lcd (also only dvi connector available), also using the same dvi-hdmi converter.
yea that's what I thought it was as well... but after 10 mins of just plugging it in and unplugging it finally worked...weird how sometimes that's all things need haha
