Our Verdict

Dell U4025QW

Dell U5226KW

The Dell U4025QW and the Dell U5226KW are both ultrawide monitors in the Dell UltraSharp lineup. The U5226KW has a bigger 52-inch screen, offering more space to multitask. Despite having the lower resolution, the U4025QW has higher pixel density and sharper text clarity. They have many of the same features otherwise, but the U5226KW has extra video ports, while the U4025QW supports daisy chaining and HDR.
