My largest monitor says that it is best to be viewed with a dual graphics card installed and I must have a dual graphics card installed to view multiple monitors (the smaller for input, larger for output) correct.? I do not see a graphics card any where on this configuration, is that a problem.? if so, can I have a graphics card seperatley installed.?
