What reviewers say

The review calls the Dell Alienware AW3423DWF "one of the best gaming monitors available," noting that it offers virtually identical image quality and performance to its predecessor while being $150 cheaper. It highlights the monitor’s flawless wide‑angle viewing, precise color accuracy (Delta E < 2), broad DCI‑P3/Adobe RGB coverage, high brightness for SDR and HDR, infinite contrast from OLED technology, and very low input lag. The reviewer also praises its 165 Hz refresh rate with FreeSync Premium Pro, instant pixel response, and a host of gaming‑centric features such as a joystick‑controlled OSD, Dark Stabilizer, crosshair overlays, and Picture‑in‑Picture support.

Our take

Based on 6 reviews

Five of the six reviews praise the Alienware AW3423DWF’s QD-OLED panel for its near-infinite contrast, precise color accuracy, and fast response times, with reviewers noting the 165Hz refresh rate and 1800R curvature as key strengths. Basic Tutorials is the sole outlier, citing QD-OLED color fringing around hard edges, while most outlets highlight the monitor’s excellent viewing angles and low input lag.

Reviewers consistently note the absence of HDMI 2.1 and USB-C ports as connectivity drawbacks, and some point out modest HDR brightness and a large stand. Buyers seeking top-tier image quality and fast gaming performance will find it compelling, though those prioritizing modern connectivity or flawless edge rendering may want to look elsewhere.
