I plan on buying another monitor, a Dell S2240M to match the one i already have, the thing is i also have a tv im using as a second monitor currently that i plan on occasionally using as a third monitor (hooked up via hdmi). I do have two graphics cards but when i tried to hook up two tvs to est it out, via hdmi to my computer as a second and third monitor i only got one to show up. I don't want to buy the new monitor and find out whenever i want to use the tv i have to unplug things, so is there anyway to tell if two monitors hooked up via dvi and one tv via hdmi would work?
