Overview
Built around an unusual 3:2 canvas, the BenQ RD280U is a 28.2-inch 3840 x 2560 IPS monitor aimed at programmers and productivity users who want more vertical space than a 16:9 screen. Its 163 PPI density, Nano Matte Panel, 100% sRGB and 95% DCI-P3 coverage suit sharp text, long documents and mixed creative work. The main USB-C connection supplies up to 90 W, while a second Type-C port lists MST, data transfer and 7.5 W power for daisy chaining. The stand provides 110 mm height adjustment, ±15° swivel and tilt, but no pivot. Motion performance is ordinary at 60 Hz and 5 ms GtG, while DisplayHDR 400 has only 50 cd/m² of stated brightness headroom. Buy it if the taller 3:2 workspace suits your workflow; skip it if fast gaming, portrait rotation or forceful HDR matters more.

HDR & Brightness Reality
The RD280U carries DisplayHDR 400 and HDR10, but its brightness rises only from 350 cd/m² typical to 400 cd/m² peak. That 50 cd/m² gap leaves little room for bright highlights. The 1,200:1 contrast ratio is normal for an IPS display, and no local dimming is listed. HDR content will be accepted, but the hardware figures point to basic HDR presentation rather than a wide luminance range.

Frequently Asked Questions
01 Why does the RD280U use a 3:2 aspect ratio instead of 16:9? +
The 3840 x 2560 panel provides extra vertical space for code, documents and web pages. It is less conventional for widescreen video, which may leave larger unused areas.
02 Is the 400 cd/m² HDR peak meaningfully above normal brightness? +
Not by much. Typical brightness is 350 cd/m², so the sheet shows only 50 cd/m² of extra peak output.
03 What can the 90 W USB-C port handle on a desk? +
It is listed for video through DisplayPort Alt Mode, 5 Gbps data and up to 90 W power. That can support many compatible laptops through one cable, although high-power models may still need their own adapter.
04 Why is there no pivot despite the coding focus? +
The stand provides 110 mm height adjustment, ±15° swivel and -5° to +20° tilt, but Pivot is explicitly listed as No. A VESA arm would be needed for physical portrait rotation.
05 What is missing for serious gaming on the RD280U? +
The panel is limited to 60 Hz, has a 5 ms GtG claim and lists no adaptive sync. Its strengths are workspace shape and clarity, not motion performance.
