The Dell U4021QW is great for productivity thanks to its 40-inch widescreen and accurate color reproduction. It lacks a variable refresh rate, and HDR support, and has grayish blacks, making it unsuitable for pro gamers.

Product Snapshot

Overview

The Dell UltraSharp U4021QW is a high-end monitor released in 2021 that promises to deliver excellent picture quality thanks to its superb 5K resolution. The monitor features a curved screen that provides wide viewing angles, and with 0.4-inch bezels, the display is very easily adaptable to a multi-screen setup. The monitor’s 40-inch screen offers a wider field of view compared to the 34-inch LG 34GP83A-B, and with the stand’s great ergonomics, users will be able to easily adjust the display according to their preference. Make sure to read through the rest of this Dell UltraSharp U4021QW review to see how well it compares to other top-rated computer monitors.

Consensus

our Verdict

The Dell U4021QW is a great pick for professionals and designers who need a large screen for increased productivity or color-accurate photo editing. However, gamers should look elsewhere, as this monitor has a low 60Hz refresh rate and doesn’t support FreeSync or Adaptive-Sync technologies. On the plus side, it has wide viewing angles, but its lack of HDR support and grayish blacks mean it’s not ideal for movie-watching.

Reason to Buy

High 5K resolution delivers sharp images
Ultrawide screen is ideal for multitasking
Great ergonomics
Wide viewing angles

Reason to Avoid

No support for HDR content
Low 60Hz refresh rate
No support for FreeSync or G-Sync
Low contrast ratio and grayish blacks
