BenQ RD280UG MoonHalo Monitor Review: 120Hz and 3:2 Aspect Ratio Redefine Coding Comfort

BenQ continues to refine its programming-focused displays with the new RD280UG MoonHalo monitor, building on the success of its 32-inch predecessor. This 28-inch 4K display introduces two groundbreaking features for productivity-focused users: an uncommon 3:2 aspect ratio and 120Hz refresh rate, packaged in an ergonomic design that complements modern macOS workflows.

The 3:2 aspect ratio (3840×2560 resolution) provides 33% more vertical space than traditional 16:9 displays, a configuration particularly beneficial for coding and writing. shows how this format allows viewing more lines of code or text without requiring excessive monitor height. The dimensions prove particularly effective when rotated to portrait orientation, where the aspect ratio becomes 2:3 - ideal for reading documentation or comparing code sections side-by-side.

Display performance sees significant upgrades with the 120Hz refresh rate, a first for BenQ's programming monitors. This enhancement dramatically improves text clarity during scrolling and makes UI interactions feel more responsive compared to standard 60Hz displays. macOS users will appreciate the seamless integration - the monitor automatically negotiates the 120Hz refresh rate when connected via its USB-C port, which also delivers 90W power delivery to charge laptops.

demonstrates the monitor's flexible connectivity options. The RD280UG supports daisy-chaining through its USB-C and DisplayPort outputs, enabling clean multi-monitor setups with M-series Macs. In testing with an M4 MacBook Air, the system maintained smooth performance when driving the BenQ display alongside another 5K monitor and the laptop's internal screen.

Key productivity features include:

• Nano Matte Panel: Reduces glare without the graininess of standard matte coatings
• Coding Mode: Optimizes contrast for dark-themed IDEs with 2000:1 contrast ratio
• MoonHalo 2.0: Adaptive bias lighting that reduces eye strain
• Paper Color Mode: Simulates e-ink display characteristics for long reading sessions

highlights the monitor's eye care technology, including its ultra-low brightness mode (down to 5 cd/m²) for nighttime work. The included stand offers 150mm height adjustment, tilt, swivel, and pivot functionality, while thoughtful touches like brown cable management clips maintain a professional aesthetic.

Priced at $699.99 ($60 off MSRP), the RD280UG competes favorably with Apple's Studio Display while offering unique productivity-oriented features. Developers working with Xcode or Visual Studio Code will particularly appreciate the combination of high refresh rate and optimal aspect ratio, while writers benefit from the text-focused display modes.

The monitor is available through Amazon and BenQ's official store, complete with a 3-year warranty. For macOS users seeking a display that bridges the gap between coding efficiency and visual comfort, the RD280UG sets a new standard in its category.
