One cable, one desk: how the USB-C hub works
Most offices still connect a laptop with a power brick, an HDMI cable, a USB dock and a network cable. The Dell UltraSharp U3223QE replaces all of them with a single USB-C connection. That one cable carries the 4K video signal, charges the laptop at up to 90W, connects the USB devices plugged into the monitor and passes through a wired RJ45 Ethernet connection.
On the back and underside you get five fast USB 3.2 Gen 2 ports for keyboards, mice, webcams and external drives, plus a downstream USB-C port and a 3.5mm audio output. A DisplayPort 1.4 output lets you daisy-chain a second monitor through MST, while HDMI 2.0 and DisplayPort 1.4 inputs connect desktops, workstations and older laptops.
Eye comfort is covered too. The flicker-free backlight and ComfortView Plus reduce harmful blue light without turning the picture yellow, and the monitor is TÜV Rheinland certified for low blue light. The stand adjusts 150mm in height and pivots into portrait, and a standard 100 × 100mm VESA mount lets you move the screen onto an arm if you prefer.
