[NAME] M  - Dell Regulatory Model D28M is an XPS 8940. If you have an add-in video card (AMD or NVidia), it very likely supports more than one monitor, but you might need a video adapter if your monitors don't support the ports available on the card, depending on what you have. Onboard Graphics is standard so if you only have onboard Intel UHD Graphics, you have both an HDMI 1.4 port and a DisplayPort for integrated graphics. You can use both of these at the same time, with adapters if necessary, but performance may suffer. If you have also have an add-in video card, you can use one port on the add-in video card plus one onboard graphics port, but at least one monitor should be connected directly to the add-in video card first. So you could use HDMI on the card for first HDMI monitor and onboard HDMI for second HDMI monitor... EDIT: Guess I'm a slow typer...
Just recieved my new XPS D28M. I can't believe there is no way to hook up a second monitor. Can someone get back to me with the most cost efficient way to get a second one going?
