Monitor Dell Pro P P3426WEB 34" (86.4 cm) Curved IPS LCD 3440 x 1440 UWQHD, 100Hz, USB-C PD 90W, Speakers, VESA
The Dell Pro P P3426WEB is a 34" (86.4 cm) curved IPS LCD monitor with a 3440 x 1440 UWQHD resolution and 0.233 mm pixel pitch. Designed for productivity and multitasking, this 21:9 ultrawide display provides extended horizontal workspace for spreadsheets, timelines, and side-by-side documents. The curved panel reduces peripheral distortion and improves viewing comfort across the wide screen. Integrated speakers and a built-in webcam with microphone support everyday collaboration without requiring extra peripherals, while USB-C with Power Delivery up to 90 W enables single-cable video, data and laptop charging for streamlined desk setups.
The 34" UWQHD IPS panel delivers consistent colours and wide viewing angles suitable for long working sessions. The 100 Hz refresh rate and 8 ms response time provide smoother motion for video playback and on-screen transitions. Curved screen geometry enhances immersion and reduces eye movement across the ultrawide workspace. USB-C Power Delivery up to 90 W simplifies connectivity by combining video, data and power over one cable, and built-in speakers plus webcam reduce the need for separate accessories.
Place the monitor on a stable desk surface or attach it to a VESA-compatible arm or mount. Connect a source device using DisplayPort, HDMI or the USB-C port; when using USB-C, the monitor can deliver up to 90 W to charge a connected laptop while handling video and data. Adjust the monitor position and tilt for comfortable viewing and use the operating system display settings to set the native 3440 x 1440 resolution and preferred refresh rate. Use the built-in webcam and microphone for conferencing directly in meeting applications, and control audio output through the integrated speakers or external speakers if preferred.
For optimal image quality, set your graphics output to the native 3440 x 1440 resolution and 100 Hz refresh rate where supported. When using the monitor for long periods, position it so the top of the screen is at or slightly below eye level and take regular breaks to reduce eye strain. Use USB-C for single-cable convenience and ensure your laptop supports 90 W PD if you require full charging throughput.
Professional clarity in every lighting condition — the built-in Sony Starvis 5MP sensor and QHD camera with HDR deliver balanced exposure and detailed video so you always look sharp on calls. AI Auto Framing keeps you centered as you move, ensuring the focus stays on you throughout meetings.

Works smoothly with major platforms — certified for Microsoft Teams and Zoom, with a quick-access touch control to launch calls instantly. Integrated Windows Hello sign-in and a mechanical tilt-and-shutter privacy cover provide secure, password-free access and physical privacy control for worry-free collaboration.

Streamline your workspace: one USB-C cable transmits video, data, Ethernet and delivers up to 90W power, reducing clutter while keeping your laptop charged and connected.

Connect or charge devices fast with easily reachable pop-out ports, including a USB-C port (up to 15W charging) and a USB Type-A port for peripherals.

Energy efficiency class is a standard classification that is used all over Europe and which is understandable at first sight. Products can be efficiently compared according to classes, starting from A (the most energy efficient class), and ending with G (the most energy-intensive class). The classification of energy efficiency is based on annual energy consumption which is being calculated on the basis of several different parameters.
