The BenQ RD280U is a purpose-built 28-inch 3:2 4K+ programming monitor designed to provide developers and programmers with more vertical screen space, exceptional text clarity and a focused coding environment. With its unusual 3:2 aspect ratio, 3840 × 2560 resolution, 164 PPI, and IPS panel, the RD280U provides a taller workspace that allows programmers to view more lines of code with less scrolling.

BenQ combines this expansive display with programming-focused technologies such as Coding Dark Theme, Coding Light Theme, Superior Code Differentiation, Fine-Coated Nano Matte Panel and Coding HotKey. The integrated MoonHalo backlight adds a customisable ambient lighting experience, while 90W USB-C connectivity, KVM and Desktop Partition help streamline modern developer workstations.

3:2 4K+ Display for More Vertical Coding Space

The standout feature of the BenQ RD280U is its 3:2 aspect ratio. Compared with conventional 16:9 monitors, the taller screen provides additional vertical workspace, allowing developers to see more lines of code, documentation and project information simultaneously.

With a high 3840 × 2560 resolution, the RD280U delivers detailed visuals and sharp text across its 28.2-inch screen. The 164 PPI pixel density further improves text definition, making small fonts, programming syntax and interface elements appear crisp and easy to read.

IPS Panel with 95% P3 Colour Gamut

The RD280U uses an IPS panel that delivers wide 178° horizontal and vertical viewing angles, helping maintain consistent image quality when viewed from different positions.

Its 95% P3 colour gamut and support for 1.07 billion colours provide rich and detailed colour reproduction. While designed primarily for programming, the monitor is also suitable for content consumption, productivity and colour-conscious creative work.

Fine-Coated Nano Matte Panel

BenQ has equipped the RD280U with a Nano Matte display coating designed to minimise distracting reflections.

The specialised Fine-Coated Panel is particularly useful for programmers working in environments with windows, overhead lighting or other potential sources of screen reflections. By reducing visual distractions, it helps create a cleaner and more focused coding workspace.

The monitor also carries TÜV Reflection Free certification, reinforcing its focus on reducing distracting reflections during extended viewing.

BenQ MoonHalo Backlight

The integrated MoonHalo backlight creates ambient illumination behind the monitor to enhance the overall working environment.

Users can customise:

• Brightness
• Colour Temperature
• Light Modes
• Auto Dimming
• Non-stop Mode

MoonHalo is designed to provide a more comfortable and immersive workspace, particularly when coding or working in lower-light environments.

The lighting can also be conveniently controlled through BenQ Display Pilot 2, allowing users to adjust MoonHalo settings directly from their computer.

Advanced Coding Modes

The RD280U is specifically designed around the needs of programmers. Its dedicated coding modes help optimise the display for long coding sessions.

Coding Dark Theme

The Coding Dark Theme provides a darker interface designed for developers who prefer dark coding environments.

Coding Light Theme

For programmers who prefer brighter interfaces, Coding Light Theme provides an alternative viewing environment.

These dedicated modes make it easier to adapt the monitor to different programming environments and personal preferences.

Superior Code Differentiation

Clear differentiation between programming elements is essential when working with large codebases.

BenQ’s coding-focused display technology is designed to improve font clarity and code differentiation, helping programmers distinguish different elements of their code more easily.

This can be especially useful during long development sessions involving large amounts of text.

Coding HotKey & Function Bar

The dedicated Coding HotKey provides quick access to coding-related display settings.

Instead of navigating through multiple menus, programmers can quickly access their preferred coding environment through the dedicated control.

The Function Bar further improves accessibility by placing frequently used functions within easy reach.

Display Pilot 2

The RD280U works with BenQ Display Pilot 2, providing software-based control over display and productivity settings.

Display Pilot 2 enables users to manage functions such as:

• Display settings
• Desktop Partition
• Application Mode
• Software Dimming
• Circadian Mode
• MoonHalo settings

This allows users to control important monitor functions directly from their computer.

Desktop Partition for Efficient Multitasking

The Desktop Partition feature helps users organise multiple applications across the large 3:2 display.

Instead of manually resizing and positioning windows, users can select preset layouts or create customised partitions.

This is particularly useful for developers who need to work with multiple applications such as:

• Code editors
• Web browsers
• Documentation
• Terminals
• Debugging tools
• Communication applications

The additional vertical space of the 3:2 display combined with Desktop Partition creates an efficient multitasking environment.

Built-In KVM for Multi-Device Workflows

The RD280U includes a built-in KVM switch, allowing users to control multiple connected computers using a single keyboard and mouse setup.

This is useful for developers who work across different systems, such as a primary workstation and secondary laptop.

The integrated KVM reduces the need for additional peripherals and makes switching between compatible sources more convenient.

90W USB-C One-Cable Connectivity

The monitor features 90W USB Type-C connectivity, designed to simplify modern workstation setups.

A compatible USB-C connection can carry:

• Video
• Audio
• Data
• Power

This allows compatible laptops to connect to the monitor through a single cable while also receiving power.

USB-C Daisy Chaining

The RD280U supports Multi-Stream Transport (MST) through USB-C, allowing compatible displays to be connected in a daisy-chain configuration.

This can help developers create multi-monitor workstations while reducing cable clutter.

Mac compatibility note: Mac and MacBook devices support daisy chaining through Thunderbolt. Daisy chaining is not supported through HDMI or regular USB ports. Devices using Apple M1 or M2 chips are limited to a single external display under the specified configuration. Compatibility can vary depending on the Mac model and setup.

Intelligent Circadian Mode

BenQ Low Blue Light Plus includes Circadian Mode, which automatically adjusts the display’s colour temperature throughout the day.

The technology is designed to follow the natural progression from warmer evening tones to cooler daytime tones, helping create a more comfortable viewing environment throughout extended work sessions.

TÜV Certified Eye Comfort

The RD280U is designed with multiple technologies focused on long-duration viewing comfort.

These include:

• TÜV Reflection Free Certification
