Question about Dell UltraSharp U2724D

The package also contains a display port cable. You can connect the monitors together using one of the display port (be sure to use the correct port on the monitor, check for Daisy Chain) and then if you have the correct adapter you can use the second display port cable to connect master monitor to your laptop/workstation. In case you have no display port support/adapter you need to buy an extra hdmi cable
