Product Overview

Dell UltraSharp U4021QW is a premium 40-inch 2500R-curved IPS monitor designed for productivity. It offers the same vertical resolution but widens the field of view by a third, while making it more accessible with a slightly curved form factor.
This form factor allows the UltraSharp to retain a high 140ppi pixel density. It is boosted by the 10-bit IPS panel that delivers 98% DCI-P3, 100% sRGB, and 100% Rec. 709 coverage.
For productivity, Dell has also endowed the U4021QW with a powerful USB-C hub that includes not only Thunderbolt and USB-A but also USB-C downstream, with charging available not only for the upstream but also for the downstream connections. Moreover, the U4021QW packs an RJ45 port, giving laptop users ethernet access via Thunderbolt.
Naturally, the U4021QW comes with a stand that is tilt, swivel, and height adjustable. It also features ComfortView Plus, which is a built-in low blue light screen that make long use sessions easy on the eye.
Last but not least, the UltraSharp U4021QW comes with dual 9W stereo speakers that more than suffice for office use.

It also has an incredible color gamut for content creators working in the sRGB color space. While its response time is fine for casual gaming, it may be too slow for serious gamers.
