HI i have just upgraded to a 17" flatscreen from a CRT (big back) heavy thing. the cable from the CRT has an 3-way cable, the same as the LCD (below) but the extra one is a plug for the mains
(the LCD one is as above with the same conector on both ends)
i do not know which one to use the new LCD 2-way or the old 3-way
