I have an Asus G75VW-TS72 which has an nVidia GTX 670M and I have been running one external monitor for a while now perfectly fine. I found an older monitor laying around the house and tried to use it however in the display settings the older monitor is blacked out and is "disconnected". The first, newer, monitor is connected from the HDMI port but I used an HDMI --> DVI converter and the second is through VGA. Why am I not able to use both external monitors at once? Is it my settings or my graphics card?
