BENQ RD320UA 31.5 Inch 4K UHD 60Hz IPS Panel 98% SRGB 5MS Adaptive Freesync Gaming Monitor

The BenQ RD320UA is a 31.5-inch 4K UHD (3840 × 2160) IPS monitor purpose-built for developers, creative professionals, and power users who spend long hours in front of a screen. At 140 PPI, text and code render with razor-sharp precision, making it easier to read fine syntax at a glance without zooming or squinting. The Nano Matte panel coating significantly reduces glare and ambient reflections, helping maintain focus during both day and night work sessions. BenQ's dedicated Coding Modes — available in Dark Theme and Light Theme — are optimised to improve font clarity and colour differentiation between code elements, directly addressing the visual fatigue that accompanies extended development work. MoonHalo, BenQ's proprietary rear ambient backlight, allows users to customise colour temperature and brightness to match the room environment, reducing the contrast shock between screen and surroundings. Night Hours Protection employs minimum-brightness technology that lowers eye strain during late-night usage, complemented by Flicker-Free technology, Low Blue Light Plus (hardware and software), and B.I. Gen2 ambient light sensing. The monitor holds TÜV Eye Comfort 2.0 and EyeSafe 2.0 certifications, alongside Energy Star 8, TCO Certified 9, and EPEAT Bronze environmental ratings. Connectivity is comprehensive: one USB-C port delivers 90 W Power Delivery with DisplayPort Alt Mode, enabling single-cable laptop docking; a USB-C MST port supports daisy-chaining; dual HDMI 2.0 and one DisplayPort 1.4 round out video inputs. A built-in USB 3.2 hub adds two USB-A and two USB-C downstream ports. The integrated KVM switch lets one keyboard and mouse control two connected computers, while DualView Plus and PIP/PBP modes allow simultaneous display of multiple sources. The full-motion ergonomic stand offers −5° to +30° tilt, ±275° swivel, 90° pivot with Auto Pivot detection, and 130 mm height adjustment, supporting 100 × 100 mm VESA mounting. HDR10 and VESA DisplayHDR 400 support, a 2000:1 contrast ratio, 400 nits typical brightness, and a 1.07-billion-colour display complete the visual package. Firmware updates can be applied via USB without a PC connection.
