## Long description

The BenQ RD320UA is a 31.5" 4K Ultra HD programming monitor (3840 x 2160) designed for developers who need clear text rendering, flexible ergonomics and integrated lighting. Its Nano Matte IPS panel with a 2000:1 contrast ratio and 400 cd/m² typical brightness reduces reflections while delivering deep blacks and crisp fonts. The monitor includes an adjustable Ergo Arm, built-in MoonHalo lighting, USB Type-C with 90W power delivery, KVM switch, PIP/PBP and Display Pilot 2 software for tailored workflow control.
Advantages
The RD320UA offers high pixel density and a matte Nano coating that minimizes glare and improves code legibility. An elevated 2000:1 contrast ratio enhances text clarity and visual depth, while Brightness Intelligence Gen2 and TUV/ Eyesafe certifications reduce blue light and adapt brightness to ambient conditions. Integrated MoonHalo lighting with Auto Dimming and Night Hours Protection supports eye comfort in dark environments. The monitor also provides extensive connectivity (including two USB-C downstream ports and 90W USB-C upstream support), built-in speakers, VESA and pivot support, and an ergonomic arm for flexible positioning.
Suitable for
Software development and coding
Multitask workstations with multiple inputs (PIP/PBP, DualView Plus)
Office and home work requiring long screen hours and ergonomic adjustment
Users who need USB-C single-cable connectivity and device charging

Adjust MoonHalo settings and Night Hours Protection via Display Pilot 2 or let B.I. Gen2 auto-adjust brightness and color temperature based on ambient light.
Usage recommendations
For extended coding sessions enable Night Hours Protection and Brightness Intelligence Gen2, adjust MoonHalo color temperature to a warm setting in low-light conditions, and position the screen at eye level using the Ergo Arm to reduce neck strain.
