    Great for work but it is big.

    I LOVE this monitor. Was using 2 smaller monitors before this. Now I can easily see my screens without squinting and divide it into 4 quadrants if I want several screens open simultaneously.

    Not as advertised

    I have multiple computers I need to connect to a single monitor, though it works, It requires lots of cables.This is what I was trying to eliminate. I have an NUC, my work laptop, my MacBook Pro all on my desk.I do use wired KB and Mouse, just my preference better key selection, speed and precision.With that said this adds significantly more cables to manage, secondly the Dell Display Manager software is buggy,I couldn’t get Network KVM working without issues and switching between PC’s didn’t always work, or the resolution didn’t always resize correctly.The monitor was great and did its job bu

    Screen cracked on arrival.

    "This is extremely disappointing after a long wait and then very carefully removing my large screen and making room for this 4 k machine and then plugging it in and seeing a crack across the screen and then one down the side.

    Geniş, çok geniş

    Bağlantı arayüzleri fazlaca, ofis kullanımı için ideal. Çift cihaz bağlanabiliyor. Ethernet bağlantısı var, hoparlör var, daha ne olsun.
