The Dell Pro Plus P3425WE is a 34-inch curved ultrawide monitor designed for professionals who need to view and manage multiple applications simultaneously. It combines a 3440 × 1440 WQHD resolution with USB-C connectivity offering up to 90W power delivery, Ethernet, and KVM switching—eliminating the need for separate cables and peripherals when working across multiple systems.

Why This Product

• 34-inch ultrawide curved display — WQHD 3440 × 1440 resolution with 21:9 aspect ratio and IPS panel technology for consistent color across wide viewing angles. At 110 PPI, text and images remain sharp for extended work sessions.
• Single USB-C cable powers and connects — The upstream USB-C port delivers up to 90W power to your device while simultaneously transmitting video, data, and Ethernet. Eliminates the tangle of separate power adapters and cables.
• KVM switching between two computers — Control two connected PCs with a single keyboard and mouse using the built-in KVM feature. Switch between systems without touching your desk.
• Dual-monitor layout on one screen — Picture-in-Picture and Picture-by-Picture modes let you view and work on content from two computers side by side on the same display.
• Tested Mac compatibility — Certified to work with macOS devices. Daisy chaining via Thunderbolt requires compatible hardware; check your device's specifications first.

Compatibility

• ✓ Connects via USB-C (with DisplayPort Alt Mode and up to 90W power delivery) or HDMI and DisplayPort inputs for video.
• ✓ Includes RJ45 Ethernet port and three USB Type-A ports (5Gbps) plus one USB-C downstream port (15W charging) for peripheral connectivity.
• ✓ Works with Windows PCs and laptops via USB-C, HDMI, or DisplayPort.
• Note: Mac and MacBook compatibility confirmed; however, Thunderbolt daisy chaining of multiple displays requires compatible hardware. Verify your device's M-series chip or processor for full feature support.
• Note: KVM and dual-input modes (PiP/PbP) require two video sources connected simultaneously. Single-source setups will use only one input.

Best For / Trade-offs

Best for:

• Professionals managing multiple applications or documents at once
• Developers, data analysts, and financial professionals who benefit from expanded screen real estate
• Users who want to consolidate power, data, and Ethernet into a single USB-C connection
• Teams switching between two computers without a KVM switch or cable swapping
• Mac and PC hybrid workflows requiring compatibility with both ecosystems

Trade-offs:

• Gaming and high-refresh work: maximum 100 Hz refresh rate and 5-8 ms response times suit productivity over competitive gaming or real-time animation.
• Daisy-chain setups without Thunderbolt: connecting multiple displays via a single cable requires Thunderbolt-capable hardware; standard USB-C devices cannot daisy chain.
• Single-monitor simplicity on a budget: this monitor's cost and feature set (KVM, dual-input modes, Ethernet) target multi-device professionals, not single-system users.
• Portable or mobile work: 6.9 kg weight and desktop form factor make it a stationary workplace tool, not a travel or temporary-site monitor.
