my 360 won't turn on cuz my monitor isn't on and monitor won't turn on cuz the xbox isn't on. i turn on the monitor first. it says no input detected and goes to standby. the xbox start screen doesn't load untill it detects that it's connected to a display what do i do? setup: the monitor i have is an acer p235h. with vga and dvi input. i've got the xbox hooked up to the dvi through an hdmi adapter. i'm also using the proprietry xbox cable slashed in half so i can use an optical cable to get surround sound.
