Dell Pro 34 Plus P3425WE: 34-inch ultrawide for work

Dell has introduced the Pro 34 Plus P3425WE, a 34-inch (3440×1440) ultrawide IPS monitor aimed at office use. The panel carries a 100Hz refresh rate, supports up to 90 watts of USB-C power delivery and includes a built-in KVM switch. UK retail listings place the monitor between about £410 and £450, with Dell UK pricing near £440.

The P3425WE ships with a silver adjustable stand, a near-bezel display and a rear four-way joystick for on-screen controls. An on-screen KVM setup guide appears at first boot. Dell provides Display Manager software for Windows and macOS to configure the KVM, enable Picture-in-Picture and Picture-by-Picture modes, arrange window snapping across the ultrawide panel, and allow remote monitor management for IT teams.

Stand adjustments offer 150 millimeters of height, wide swivel and tilt ranges and no portrait pivot. The stand includes an oval cutout for cable routing. The angled cutout can make fitting multiple cables and the mains IEC plug awkward in tight setups.

Connectivity includes one HDMI 2.1 port, one DisplayPort 1.4 input, an upstream USB-C port with DisplayPort Alt Mode, data and up to 90W power delivery, a USB-B upstream option, an RJ45 port, three rear USB-A downstream ports, a front USB-C downstream port and a 3.5mm audio output. A drop-down panel under the bottom bezel hides one front USB-A and one USB-C port for easy access.

The screen uses a 3800R curved IPS panel with a gentler curve than many ultrawide displays. Dell lists panel coverage at 99% sRGB, a 1,500:1 contrast ratio and 350 cd/m² peak brightness. Independent measurements found roughly 94% sRGB coverage, contrast near 1,400:1, and a measured white point close to the 6,500K standard. Brightness reaches near the claimed peak at maximum settings. Factory default brightness registers around 200 cd/m² when set to 75%.

Measured average Delta E was about 2.3, indicating natural color reproduction that stops short of studio-grade accuracy. The panel reproduces some greens, yellows and reds beyond the standard sRGB gamut, which can make certain tones appear brighter than sRGB reference.

The monitor lacks HDR and adaptive sync support. Dell lists a 5ms gray-to-gray response time in GtG Fast Mode. Switching overdrive from Normal to Fast reduces motion blur and improves moving-image detail, with some inverse ghosting visible in certain scenes. The anti-glare matte coating helps control reflections in bright rooms.

Price places the P3425WE above several other 34-inch ultrawide models. The cost reflects the inclusion of 90W USB-C power delivery, the built-in KVM and enterprise features such as remote management. The P3425WE includes USB-C power, a KVM switch and Picture-in-Picture/Picture-by-Picture modes for multi-device desks.
