So I got a free monitor from the place i work (they were throwing it away but it was fully functional). Its an old-ish VGA only and it works with my Dvi to VGA adapter that came with my graphics card (R9 270x His Iceq x2). So the graphics card only has one dvi port, so i bought an hdmi to dvi cable. it turns out the cable wont work, any idea why?
