Dell 34 Plus USB-C Curved Monitor S3425DW - 34" UWQHD 120Hz
The Dell 34 Plus USB-C Curved Monitor S3425DW is a 34-inch ultrawide designed for professionals and gamers who need expansive screen real estate with high colour accuracy and smooth motion. Its USB-C connection powers and displays simultaneously, eliminating cable clutter, while the 120Hz refresh rate and 1ms response time suit both creative work and competitive gaming.
Why this product
USB-C powers and displays in one cable
The USB-C upstream port delivers up to 65W of power delivery via DisplayPort 1.4 Alternate Mode, so you can run the monitor and charge a laptop from a single connection.
99% sRGB and 95% DCI-P3 colour coverage
Colour-critical work—photo editing, video grading, graphic design—stays accurate across both sRGB and cinema colour spaces with minimal drift.
3000:1 contrast and VA panel depth
The VA panel produces deeper blacks and higher contrast than IPS, with HDR10 support for added dimensionality in film and games.
AMD FreeSync Premium up to 120Hz
Eliminates tearing and stutter in compatible games with variable refresh rate from AMD graphics cards, paired with a 1ms extreme-mode response time.
Blue light reduction to ≤35%
ComfortView Plus technology cuts harmful blue light while maintaining colour accuracy, reducing eye strain during extended work sessions.
