![]() In any case, not all USB-C ports accept video input and provide power, but that definitely doesn't make them "pointless". But because the U2722D avoids that third "fully featured" USB-C port that can accept video, and therefore can also use a lower wattage power supply since it doesn't have to account for providing enough power to run a laptop, it can of course cost less than the U2722DE - and if you're a company buying dozens or hundreds of these displays to be used with desktop systems, as many Dell business customers will be, those savings can add up. A "data-only" USB-C port such as the upstream port found on the U2722D is better suited to use cases involving a desktop PC, where you'd have a separate video cable and no need for drawing power from the display. If you expected to use this display with a laptop that has a USB-C port that can send video and receive power, then yes the U2722DE would have been a better choice, since it includes a third USB-C port that supports all of that. The latter USB-C port is a downstream port meant to be used for connecting peripherals, so if you had a USB-C flash drive, hard drive, or smartphone charging cable, you could connect it there. Think of it like the display having a USB hub built into it and that upstream port being the cable that connects the USB hub to your PC, because that's exactly what's going on. Making that connection back to a PC allows you to plug USB peripherals into the display's other USB ports and have them usable with your PC. The former is an "upstream" port, which is used to create a USB data path to the source PC. The U2722D has two USB-C ports, one next to the DisplayPort output (which is used for daisy chaining), and another close to the front and the right edge of the display.
