Product Snapshot


The Dell U3818DW is the brand’s mid-level model released in 2017. It promises to deliver exceptional image clarity over other monitors at mid-level models thanks to its excellent sRGB color space and high-resolution screen coverage. It also has a wider variety of ports than its competitor, the LG 38WN95C-W, because of the extra USB ports (one of which is USB Type C connectivity). It’s an excellent monitor for those working on various video editing projects or just for office work in general. In addition, the Dell U3818DW has a striking color gradient, a sturdy build, and powerful and clear speakers.
