Dell U3223QE UltraSharp 32" USB-C hub monitor

This monitor has an IPS panel (In-Plane-Switching). IPS technology combines two major advantages. Firstly, it provides a very wide viewing angle so that several viewers can easily recognise the content at the same time. Secondly, IPS technology guarantees high colour fidelity. This monitor is therefore also suitable for more colour-sensitive applications such as image editing.

The Mnitor also has an integrated USB hub. This means that suitable connection options for your peripheral devices and storage media are just a flick of the wrist away.

Protect your eyes, the "Flicker-Free" technology prevents annoying screen flickering, which has a tiring effect on the eyes over time. Short-wave blue light, which has a similar effect on the retina as UV radiation, is not only unpleasant but also harmful. This Dell monitor has "ComfortView" technology, which filters out this light component.

Adjust the monitor according to your needs: in height, tilt it up and down, swivel it to the left or right, or rotate it 90° into portrait format (pivot). The perfect monitor alignment for any sitting position or activity is just a flick of the wrist away.

With the integrated KVM switch, you can connect peripheral devices (e.g. mouse and keyboard) to the monitor's USB hub and connect the monitor to two computers simultaneously. For example, you can operate your laptop and your desktop computer with the same mouse/keyboard set and switch back and forth between the two computers on the monitor.

This monitor has an integrated USB hub which gives you the right connection options for your peripheral devices and storage media.
