Some have issues with such things. I find a pair of dual display cards is nice but many folk need support which can drive the cost way up. Or they don't have a PC with a big enough power supply but the list goes on and on.
Try a pair of cards first.
Hi! I have 4 displays (3 full hd with hdmi/dvi and 1 with vga) and I want to connect them to my computer in extended desktop mode.
Should I buy two cheap graphic cards? Is there a solution with only 1 graphic card? What should I do to connect them? I don't play games or watch movies, I just want to work on extended desktop.
