Plug them both in then go to adjust resolution and pick extend desktop display. Arrange the monitors there however you want by dragging the "1" and "2" boxes around. Click ok. It's that easy.
Hi, I have 2 DVI slots filled with dual monitors and one HDMI slot free which I'd like to use to add a third monitor. I want the new monitor to spread my work further across (rather than duplicate). Im using an ATI Radeon 3000 card. Does your answer apply to this as well? thanks.
