I have a Dell Inspiron 5594 with an HDMI port, two USB 3.1 Gen 1 ports, and a USB 2.0 port. I would like to have two extended monitors if possible, but will settle for one if possible. I have called Dell too many times and they tell me it can be done, but the keep sending me cables and accessories that do not work. Is it possible with this machine? How can I find out? If it can be done, how can I do it?
