## Long description

BenQ RD320U is a 31.5" 4K Ultra HD programming monitor (3840 x 2160) designed for developers and professionals who need clear text rendering and ergonomic adjustability. The monitor uses an IPS Nano Matte panel with a 2000:1 contrast ratio, 5 ms response time and 400 cd/m² typical brightness. Built-in features include MoonHalo backlight, Night Hours Protection, Brightness Intelligence Gen2, USB Type-C (90W) with daisy-chain support via MST, DualView Plus with PIP/PBP, KVM switching, built-in speakers, VESA mount and ergonomic stand with height, tilt, pivot and swivel adjustments.
Advantages
The RD320U offers high pixel density and strong contrast for sharp code and detailed visuals, reduced reflections from a nano matte surface, and a range of eye-care technologies such as Night Hours Protection, Brightness Intelligence Gen2 and Circadian Mode. Integrated MoonHalo backlighting with adjustable color temperature and auto-dimming improves focus in dark or low-light environments. Extensive connectivity including 90W USB Type-C, KVM and Multi-Stream Transport enables single-cable charging, daisy-chaining (MST) and easy switching between multiple sources.

How to use
Connect your primary computer using USB Type-C for video, data and up to 90W charging, or use HDMI/DisplayPort as alternatives. Use the Function Bar and Coding HotKey to switch to coding modes quickly. Configure MoonHalo, Night Hours Protection, Brightness Intelligence Gen2 and other features via Display Pilot 2 software to match your working schedule and lighting conditions. For multi-display setups, enable MST daisy chaining from the USB Type-C source or use PIP/PBP and DualView Plus to show multiple inputs simultaneously. For Mac devices, follow Apple guidance: daisy chaining is supported only via Thunderbolt and M1/M2 Macs support a single external display.
Usage recommendations
For prolonged coding sessions, enable Night Hours Protection or Circadian Mode and adjust MoonHalo brightness and color temperature to reduce eye strain. Use the ergonomic stand or VESA mount to position the screen so the top of the display is at or slightly below eye level and keep an arm’s length distance from the screen. When connecting multiple displays, prefer USB Type-C with MST-capable hosts or Thunderbolt for Mac to ensure reliable daisy chaining.
