our Verdict
Reviewers were impressed by the Dell S3422DW. Commenting about this unit’s 144Hz refresh rate, fast 4.5 ms response time, and short 4.5 ms input lag, they recommended it for gaming. Browse our HP OMEN 27C review for a smaller curved monitor. Analysts at RTINGS were pleased with the monitor’s excellent black uniformity and high contrast ratio, endorsing it for darkroom movie watching and gameplay. Users seeking a model with RGB lighting can browse our Gigabyte AORUS AD27QD review. This device’s 34-inch 3440×1440 format also pleased product testers, who described this model as immersive. Experts at Display Ninja endorse the Dell S3422DW monitor for movies and general use, and they enjoyed using the massive 3440 x 1440 34-inch screen with high dynamic range tech. However, reviewers were also left unimpressed by this unit’s narrow viewing angles, which is typical on other VA-panel devices, including the Dell S3222DGM. They were also disappointed to find that G-SYNC compatibility doesn’t work at frame rates below 60fps, and they noticed some black smearing in dark scenes.
ReasonS to Buy
- Outstanding input lag
- Excellent response time at the maximum refresh rate
- Large screen with a crisp resolution
Reason to Avoid
