I'm planning on wall mounting a 23" Asus monitor with my 360 and MB hooked up to it. The 360 will be through hdmi and the mb is through dvi. Since the monitor has both inputs, can I hook up both cables to it and just luke change the channels to be on hdmi or dvi??
That's what multiple input monitors are designed for. But depending on the monitor, you may have to do this manually or a remote may be included. A model number would help. In my case, my monitor is also an HDTV and came with a remote, so the input can be switched using that.
