BenQ RD280UA 28.2-Inch 4K UHD Programming Monitor with 3:2 Aspect Ratio and MoonHalo Bias Light

The BenQ RD280UA is a 28.2-inch professional programming monitor engineered around the needs of developers and coders. Its rare 3:2 aspect ratio at a native resolution of 3840 x 2560 pixels delivers significantly more vertical screen real estate than conventional 16:9 panels, reducing the need to scroll through long codebases and enabling side- side file comparison with ease. The IPS-Type LCD panel offers wide 178° horizontal and vertical viewing angles, a 1200:1 contrast ratio, and a 10-bit color depth supporting 1.07 billion colours. Coverage of 95% DCI-P3 ensures colour-accurate output for mixed workflows that include media review alongside coding. Brightness peaks at 400 nits in HDR10 mode and sustains at 350 nits, while the anti-glare, matte Fine-Coated Panel finish reduces reflections for distraction-free extended sessions. Pixel density is 164 ppi at a dot pitch of 0.1552 x 0.1552 mm, producing crisp, sharp text at comfortable font sizes. BenQ’s MoonHalo built-in bias light system offers adjustable colour temperature, brightness, and light modes. When paired with the Display Pilot 2 software, users can control MoonHalo settings, set application-specific colour modes, partition the desktop, and assign hotkeys directly from their PC. Brightness Intelligence Gen2 (B.I. Gen2) automatically adjusts screen brightness based on ambient light conditions, and Circadian Mode shifts colour temperature throughout the day to mirror natural light cycles. The monitor holds TÜV Rheinland Reflection-Free and Low Blue Light certifications, as well as Eyesafe 2.0 certification. A dedicated Coding HotKey and Function Bar on the monitor itself provides instant access to coding display presets. Connectivity is comprehensive: one HDMI 2.0 port, one DisplayPort 1.4 port, two USB-C 3.2 Gen 1 ports with DisplayPort Alt Mode, three USB-A 3.2 Gen 1 ports, and one USB-B 3.2 Gen 1 upstream port. The USB-C port delivers up to 90W Power Delivery, enabling single-cable laptop connectivity. Multi-Stream Transport over USB-C supports daisy-chaining additional displays. A built-in KVM switch allows keyboard and mouse sharing between two connected devices. Built-in speakers (2 x 2W) and a 3.5mm headphone output complete the audio provisions. The ergonomic stand adjusts 130mm in height, tilts 5° to +20°, rotates 90° for portrait orientation, and swivels up to 275° in each direction. VESA 100 x 100mm mounting is supported. The monitor is certified ENERGY STAR 8.0, TCO Certified 9.0, and EPEAT Bronze, reflecting a measurable commitment to energy efficiency and sustainable materials.
