Dell 34 Plus USB-C Curved Monitor S3425DW - Immersive 34in 21:9

Our review of the Dell 34 Plus USB-C Curved Monitor S3425DW concludes it is an excellent mid-range ultrawide for users who want immersive visuals with reliable color and simple connectivity. The single biggest reason to buy is the combination of a 34in 21:9 curved VA panel that delivers deep contrast and wide color coverage alongside a convenient USB-C connection that can carry video and up to 65W of power, keeping a laptop setup clean. It balances everyday productivity, media playback and light gaming with features that favor comfort and color accuracy.

Key Features

• 34in Curved VA panel: The 3440 x 1440 ultrawide screen provides an immersive field of view and strong perceived depth for movies and multitasking.
• High contrast and HDR readiness: A 3000:1 contrast ratio and VA technology deliver deep blacks and better detail in dark scenes for more realistic images.
• Wide color coverage: 99% sRGB and 95% DCI-P3 mean accurate, vibrant color for photo editing, content creation and media consumption.
• Smooth performance: AMD FreeSync Premium and a refresh rate up to 120 Hz with an ultra-low 0.03ms response time reduce tearing and motion blur in fast-moving content.
• ComfortView Plus: Integrated blue-light reduction lowers harmful emissions to 35% while preserving color accuracy for long sessions.
• USB-C single-cable setup: USB-C connectivity with up to 65W power delivery simplifies docking and reduces desktop clutter while built-in speakers improve audio without extra peripherals.

Who It's For

The Dell 34 Plus suits professionals and creatives who want a wide working canvas with strong color coverage, plus anyone who watches movies and occasionally games and prefers a curved ultrawide. Its USB-C convenience also makes it a good choice for laptop users who want a tidy single-cable setup.

Users who need the absolute fastest competitive gaming panel or the highest brightness HDR experience should look elsewhere; serious HDR grading or pro-level color-critical work may prefer specialist displays with higher brightness or hardware calibration options.

Pros & Cons

Pros

Cons

• Not the brightest HDR display compared with premium HDR monitors, so HDR impact is limited.
• Gamers seeking the fastest competitive response and esports-level features may prefer TN or IPS panels tuned for submillisecond response.
