Running two monitors means two power cables, two video cables, two stands taking up desk space, and a gap in the middle of your view that splits your workflow every time you drag a window across it. The Dell S3425DW makes that setup feel unnecessary, and Prime Day just made it easier than ever to switch. Amazon has it at $314, down from its $419 standard price and a record low for this 34-inch curved ultrawide with 3440×1440 resolution, 120Hz, a 3000:1 contrast ratio, 95% DCI-P3 color coverage, and single USB-C connectivity with 65W power delivery. This deal requires Prime membership, and the 30-day trial runs without a card.
One USB-C cable handles video, data, and 65W charging simultaneously
The single USB-C connection is the feature that changes the desk setup equation entirely. One cable from a laptop to the S3425DW handles the video signal at full 3440×1440 resolution, any USB devices connected to the monitor’s downstream ports, and 65W of power delivery to charge the laptop simultaneously. For MacBook and compatible Windows laptop users, that means docking and undocking takes one cable pull rather than disconnecting a power brick, an HDMI cable, and a USB hub separately. The desk stays clean because there’s genuinely less on it.
The 21:9 aspect ratio at 34 inches delivers 3440×1440 pixels across a screen wide enough to run two full applications side by side without either feeling cramped. A document and a browser, a spreadsheet and a video call, a code editor and a terminal: the ultrawide format handles split workflows that a standard 16:9 monitor requires two screens to manage, without the bezels, the separate power supplies, or the cable management complexity. The curved panel at this size pulls the left and right edges closer to the natural focal range of your eyes, which reduces the head movement that flat ultrawide monitors require at the edges of the frame.
The VA panel delivers a 3000:1 contrast ratio, which produces deep blacks and bright highlights that IPS panels at this price can’t match. HDR readiness, 99% sRGB, and 95% DCI-P3 color coverage make the S3425DW capable for photo and video editing work alongside the productivity use case, and AMD FreeSync Premium with 120Hz and 0.03ms response time handles gaming without tearing or ghosting. ComfortView Plus reduces blue light emissions to below 35% for all-day use without the color shift that standard blue light filters produce.
Record low on the monitor that replaces two screens with one
Two 27-inch 1440p monitors with stands, cables, and a USB hub to match the connectivity of the S3425DW typically costs more than this single ultrawide at its record low. The math changes when you factor in the desk space recovered, the cable count eliminated, and the workflow continuity that comes from a seamless 34-inch canvas rather than two panels with a physical gap between them. The re-engineered speaker system delivers deeper frequency response and higher output than the previous generation, which covers basic audio for calls and casual listening without a separate speaker added to the desk.
The S3425DW launched at $419 and has spent most of its life at or near that number. At $314, this is the lowest this monitor has ever been priced anywhere, and the Prime Day window is the only circumstance under which Dell’s ultrawide lineup reaches this level.
