Immersive 34-Inch Ultra-Wide Curved Display

At the heart of the HP P34hc G4 lies a stunning 34-inch ultra-wide curved VA panel with WQHD resolution (3440 x 1440) and a 21:9 aspect ratio . The 1500R curvature wraps around your field of view, reducing eye movement and creating a more natural, immersive viewing experience that minimizes edge distortion . With approximately 33% more horizontal screen space than a standard 16:9 monitor, this expansive canvas allows you to work with multiple windows side by side without the distraction of bezels, making it ideal for complex workflows such as video editing, financial modeling, and software development .

Smooth 100Hz Refresh Rate and Rapid Response

The P34hc G4 delivers a fluid visual experience with a 48-100Hz variable refresh rate and 5ms response time (with overdrive) . This higher refresh rate provides noticeably smoother scrolling, more fluid animations, and reduced motion blur when navigating through documents, timelines, or web pages. With a 3500:1 static contrast ratio and 85% NTSC color gamut coverage, the monitor delivers deep blacks and vibrant, true-to-life colors . The anti-glare coating reduces reflections for comfortable extended viewing .

Versatile USB-C Hub with 65W Power Delivery

One of the standout features of this monitor is its comprehensive USB-C connectivity that transforms the monitor into a true productivity hub . The USB-C port delivers up to 65W of power delivery, allowing you to charge your laptop while transmitting video, data, and audio through a single cable, eliminating the clutter of multiple adapters and chargers .

The monitor also functions as a USB hub, featuring four USB-A 3.2 Gen 1 downstream ports, a USB-B port for hub enablement, and a line-out audio port . This comprehensive connectivity includes 1x HDMI 2.0, 1x DisplayPort 1.2, and 1x USB Type-C (DisplayPort 1.2 Alt Mode, power delivery up to 65W) .

Ergonomic Design and Integrated Audio

The P34hc G4 features a sleek, modern design with a 3-sided micro-edge bezel that gives it a premium, minimalist aesthetic . The stand offers a full range of ergonomic adjustments, including height adjustment up to 100mm, tilt from -5° to +21°, and slide settings, allowing you to customize your viewing position for maximum comfort throughout the day . The VESA 100mm x 100mm mounting pattern provides flexibility for wall mounting or arm attachment for those who prefer an even cleaner desk setup .

Integrated dual 3W speakers deliver clear audio for conference calls and multimedia content, reducing the need for external speakers in compact workspaces . The monitor's compact footprint and cable management system help keep your workspace organized.

Eye Comfort and Environmental Responsibility

HP has prioritized user wellness with TÜV-certified Low Blue Light and Flicker-Free technologies that reduce eye strain without compromising color accuracy . The monitor is ENERGY STAR certified, TCO certified, and EPEAT registered, ensuring energy-efficient performance while meeting rigorous environmental standards . The product also features arsenic-free display glass, mercury-free display backlights, and low halogen construction .
