NEED HELP FAST

I just bought a new acer monitor, and want to play my 360 on it. i bought the converter but it doesnt let me switch between my desktop and the 360 screen. my comp goes in the vga and the 360 into the dvi with a vga to dvi converter. is there any way to change the input?

ummm there should be a button on your monitor that switches between digital and analog input

when i go to toggle between the two it does not detect my dvi (digital) input. its really getting annoying.

anyone?
