Dell S3425DW

The Dell S3425DW is a 34-inch curved WQHD monitor designed for immersive entertainment and productivity — all while caring for your eyes. With a 3440 x 1440 resolution, 21:9 aspect ratio, and up to 120 Hz refresh rate, it delivers a wide, fluid viewing experience. VA panel technology, a 3000:1 contrast ratio, 99% sRGB and 95% DCI-P3 color coverage, and HDR10 support ensure realistic and detailed visuals.

ComfortView Plus technology reduces harmful blue light by up to 35% without color distortion, and TÜV Rheinland Eye Comfort 4 Star certification ensures a more comfortable viewing experience. AMD FreeSync™ Premium and HDMI VRR support deliver tear-free visuals for gaming and movie watching.

Audio is powered by two built-in 5W speakers featuring five preset and one customizable sound profiles. A single USB-C cable delivers data, video, and up to 65W of power. Convenient front-facing pop-out USB-C and USB-A ports, along with HDMI and USB side ports, make connectivity seamless. The ergonomic stand supports height adjustment (up to 130 mm), tilt, and slant customization.

Dell Display and Peripheral Manager software enables display management and Easy Arrange features for efficient multitasking on both Windows and macOS. The on-screen display is easily navigated via joystick control.

The Dell S3425DW is also an environmentally conscious choice: it contains up to 85% post-consumer recycled plastic, 100% recycled aluminum, 50% recycled steel, and at least 20% recycled glass. Its packaging is made entirely from renewable materials.

The monitor is backed by a three-year Advanced Exchange Service warranty.
