The catch
BenQ RD Series 28-inch Programming Monitor
Because 3:2 is taller than widescreen video, most films leave unused space above and below.
Side by side
If long code files, documents and portrait photos are why you want a new monitor, the RD280U is the right choice. The MA270U is the better fit for a more conventional 16:9 MacBook workspace and for video. What the RD280U adds is 400 pixel rows, with no widening of the desktop.
Before you buy
Native pixel rows number 18.5% more on the RD280U, and each half of a side-by-side split stays 1920 pixels wide.
Where this comes from
(2560 − 2160) ÷ 2160 = 18.5%. Since both widths are 3840, cutting each in half gives 1920 before window borders.
The catch
Because 3:2 is taller than widescreen video, most films leave unused space above and below.
The catch
A Windows-only desk gets less out of its Mac-focused tuning.

Compare RD280U with MA270U for coding, documents, video and a shallow MacBook desk. It adds 400 pixel rows but no extra horizontal pixels.
More vertical room for code and documents, or a conventional Mac screen
Which one fits
Vertical room comes with the RD280U, and the horizontal layout does not need to be wider.
The screen shape of the MA270U suits the content.
Each begins from the same 1920 horizontal pixels.
The stand of the MA270U has 24.3 mm less depth.
In practice
Native pixel rows number 18.5% more on the RD280U, and each half of a side-by-side split stays 1920 pixels wide.
(2560 − 2160) ÷ 2160 = 18.5%. Since both widths are 3840, cutting each in half gives 1920 before window borders.
At 3.4 mm narrower than the MA270U, the RD280U still has a stand that is 24.3 mm deeper.
613.8 − 610.4 = 3.4 mm and 244.5 − 220.2 = 24.3 mm. Judge desk fit by chassis measurements and not by diagonal.
On either display, a 16:9 image at full 3840-pixel width needs 2160 rows.
3840 × 9 ÷ 16 = 2160. The RD280U is left with 2560 − 2160 = 400 rows for letterboxing or other interface elements.

BenQ, RD280U
Code and documents fit well on this tall 3:2 screen, though the usable space depends on app layout and scaling. A laptop and a desktop can both be served through USB-C and a correctly connected KVM.

BenQ, MA270U
Built around MacBook use, this matte 4K screen tailors its controls and color modes to it. It has one 90W USB-C video input and a separate downstream USB-C accessory port.
Spec by spec
| Spec | BenQ RD Series 28-inch Programming Monitor | BenQ MA Series 27-inch 4K Monitor for MacBook | In practice |
|---|---|---|---|
| Screen shape | 3:2 | 16:9 | Its extra area on the RD280U sits above and below the usual widescreen layout. |
| Native pixels | 3840 × 2560 | 3840 × 2160 | The horizontal pixel count is the same on both. |
| Pixel rows | 2560 | 2160 | Before scaling, the RD280U has 18.5% more vertical pixels. |
| Diagonal | 28.2 inches | 27 inches | This small diagonal gap counts for less than the different aspect ratios. |
| USB-C power | Up to 90W | Up to 90W | Charging gives no reason to favor the coding model. |
| Stand depth | 244.5 mm | 220.2 mm | The stand on the taller model takes up 24.3 mm more depth. |
| Chassis width | 610.4 mm | 613.8 mm | Despite the larger diagonal, the RD280U is slightly narrower. |
Trade-offs
Decision guide
The RD280U is for you if long code files, documents and portrait photos are what you buy a monitor for. A more conventional 16:9 MacBook workspace and video point to the MA270U. Keep in mind that the RD280U adds 400 pixel rows without widening the desktop.
If the bottom of a document or code pane keeps vanishing off screen, the RD280U answers that specific problem in a practical way. It brings 400 more native rows and leaves the familiar 3840-pixel width alone. How many lines you see depends on font size, scaling and toolbars, so don't turn that into a promised number of code lines.
This pair won't help if your complaint is that two side-by-side apps are each too narrow, at least not at identical scaling. Either screen divides into two 1920-pixel-wide halves. The RD280U makes each half taller, which suits documentation beside an editor more than a very wide spreadsheet.
When the monitor doubles as a 16:9 video screen, the MA270U is the easier case to make. An uncropped picture on the RD280U fills just 2160 of its 2560 pixel rows. That follows from the shape and is not a fault, yet some of the work-focused panel area sits unused during video.
