Our Verdict
LG 40WP95C-W
Dell U4025QW
The Dell U4025QW and the LG 40WP95C-W are very similar 40-inch ultrawide productivity and editing monitors. However, the Dell is the better monitor. The Dell has features the LG lacks, like a KVM switch and the ability to subdivide the screen into multiple smaller virtual monitors for easier window management. The Dell also has better image quality, as deep blacks look less gray in a dark room on the Dell, and its 120Hz screen provides a more responsive experience.
