my pc has only 1 hdmi and it is connect to tv, i want to make multiple display so i plan to buy 1 more monitor that will connect with dvi, does this situation can make the dual screen to extend?
and the sound will only get out from tv there right, so if i connect the speaker means there will be no problem?
