Dell S3425DW 34 Plus USB-C Monitor
The Dell S3425DW 34 Plus USB-C Monitor combines a 34-inch ultrawide WQHD display with a 120Hz refresh rate, a curved VA panel and versatile USB-C connectivity. Its 3440 × 1440 resolution and 21:9 aspect ratio provide an expansive workspace for multitasking, content creation and entertainment, while its 1800R curvature creates a gently curved viewing experience.
Designed for everyday productivity and immersive entertainment, the S3425DW features AMD FreeSync Premium, HDR10 support and integrated dual 5W speakers. USB-C connectivity supports DisplayPort 1.4 Alternate Mode and up to 65W power delivery, allowing a compatible laptop to transmit video and receive power through a single cable. The monitor also includes two HDMI 2.1 ports, a USB hub and an adjustable stand.
Immersive 34-Inch Ultrawide Viewing
The 34-inch VA panel combines a WQHD resolution of 3440 × 1440 with a 21:9 ultrawide aspect ratio, providing additional horizontal screen space for applications, documents and media. Its 1800R curvature follows a gentle arc across the display, while the 3000:1 native contrast ratio helps distinguish darker and brighter areas of an image. The anti-glare screen coating helps reduce reflections in brighter environments.
Smooth 120Hz Performance
With a refresh rate of up to 120Hz, the S3425DW delivers smoother motion than a conventional 60Hz display, benefiting everyday navigation, video playback and gaming. AMD FreeSync Premium helps synchronise the display's refresh rate with compatible graphics hardware to reduce screen tearing. Response time settings include 1ms grey-to-grey in Extreme mode, 3ms in Fast mode and 5ms in the standard mode.
Detailed Colour and HDR10 Support
The monitor supports 1.07 billion colours and covers 99% of the sRGB colour space and 95% of DCI-P3, making it suitable for general creative work and media consumption. HDR10 support enables compatible content to use high dynamic range, while the 300cd/m² brightness provides the display's specified brightness level. Colour performance and HDR results will depend on the source content, settings and viewing conditions.
USB-C Connectivity with 65W Power Delivery
The USB-C upstream port supports DisplayPort 1.4 Alternate Mode, video output at up to 3440 × 1440 and 120Hz, and power delivery of up to 65W. This allows a compatible laptop to connect to the monitor and receive power through one cable. The integrated USB hub adds two USB Type-A downstream ports and one USB-C downstream port, with the latter providing up to 15W power delivery for compatible devices.
HDMI 2.1 and Flexible Device Connections
Two HDMI 2.1 ports support connections to compatible desktop PCs, laptops, consoles and other video sources. Dell specifies support for WQHD resolution at up to 120Hz, including compatible HDR and variable refresh rate signals. Combined with USB-C connectivity, the available inputs make it possible to connect multiple devices without relying on a single video connection.
Integrated Speakers and Eye Comfort
Two integrated 5W speakers provide a total rated audio output of 10W for everyday listening, video calls and entertainment without requiring separate desktop speakers. Dell ComfortView Plus and its eye-comfort features are designed to help reduce exposure to blue light while retaining colour performance. The anti-glare panel also helps limit distracting reflections.
Adjustable Stand and Mounting Options
The supplied stand supports height adjustment of up to 130mm, tilt from -5° to 21° and slant adjustment of -4° to 4°. These adjustments help position the screen for different desk setups and viewing preferences. For alternative mounting arrangements, the monitor supports a standard 100 × 100mm VESA mount.
