HP P34hc G4, 34-inch WQHD USB-C Curved Monitor
The HP P34hc G4 brings an immersive, expansive workspace to demanding multitaskers, featuring a 34-inch curved VA panel with WQHD 3440 x 1440 ultrawide resolution across a 21:9 aspect ratio. Its 1500R curvature wraps the display around your field of view, reducing eye movement and creating a more natural, immersive viewing experience, while a strong 3500:1 contrast ratio (5,000,000:1 dynamic) delivers deep blacks and rich detail. With 85% NTSC colour gamut, 250 nits brightness, and wide 178°/178° viewing angles, this monitor is well suited to spreadsheet-heavy work, multi-window multitasking, and creative tasks. A single USB-C cable delivers video, data, and up to 65W of power delivery, simplifying connections to a compatible laptop, while a built-in USB hub with four USB-A ports and a USB-B upstream port supports peripheral connectivity. Height-adjustable and tilt stand, built-in 2x3W speakers, and HP’s low blue light technology round out a productivity-focused package backed by a 3-year limited warranty and TCO Certified Edge sustainability credentials.
