Overview
The BenQ RD280UA is built for one job: writing code. It is 28.2 inches in a 3:2 aspect ratio - 3840 x 2560 - which gives you noticeably more vertical lines than a 16:9 panel of the same width, and that is the entire argument for it. At 163 PPI text is crisp, the Nano Matte coating kills reflections without the grain of older matte finishes, and BenQ adds a Coding Mode and a dedicated hotkey. The stand is an ergonomic arm with 275 degrees of swivel, 130 mm of height and a 90 W USB-C port for single-cable laptop work. It runs at 60 Hz with a 5 ms response, so it is not for gaming, and DisplayHDR 400 at 1200:1 is nominal.

HDR & Brightness Reality
There is not much to say here, and that is fine - this monitor is not sold on HDR. DisplayHDR 400 with a 400 cd/m2 peak, 1200:1 contrast and no local dimming means HDR content displays but looks essentially like SDR. What actually matters on this panel is the Nano Matte coating and the Coding Mode, both of which are aimed at keeping text legible for eight hours. Judge it on that, not on its HDR badge.

Frequently Asked Questions
01 What is the point of a 3:2 monitor? +
Vertical space. At 3840 x 2560, you see far more lines of code or document text than a 16:9 panel of similar width. For programmers and writers that is the whole pitch - and it is why the RD series exists.
02 What is Nano Matte, and is it different from normal matte? +
It is BenQ's anti-glare coating that diffuses reflections without the sparkly grain older matte finishes add to text. On a text-first monitor, that difference is more noticeable than it sounds.
03 Does 3:2 cause problems with video? +
✓ Yes - 16:9 films and YouTube will letterbox with black bars top and bottom. If this is your only screen and you watch a lot of video, that is a real trade-off for the coding benefit.
04 How useful is the 275 degree swivel? +
Surprisingly. The arm stand turns almost completely around, so you can spin the screen to a colleague without moving the base. Combined with 130 mm of height and a -5 to +30 tilt, the ergonomics are genuinely good.
05 Is it any use for gaming once work is done? +
It will display games, but 60 Hz with a 5 ms response and no variable refresh means it will feel slow next to any gaming monitor. Buy it for code and keep a second screen for games.
