New on the UltraSharp U2520D compared to the Dell U2518D is the USB-C inputs. One USB-C input is a downstream charging port while the other supports DisplayPort Alt Mode, which allows you to display an image from a device and charge it at the same time. There’s also a USB port with B.C. 1.2 charging adaptability, which allows you to charge devices with a higher current. Also, you can daisy chain your screen to a second monitor with the DisplayPort output.
