"make no mistake, the 360 vga cable is the man for you. vga is by far and away the best xbox 360 connection avaiable, its also the cleanest output available, with red, green and blue each on there own discreet channel, along with two synchronisation signals to keep the picture clear and rock solid. plugging in the vga cable provides a wealth of resolutions to choose from, the most useful being 848x480,1280x768 and 1360x768. these cater for the majority of tv's."
