The catch
BenQ RD Series 28-inch Programming Monitor
Filling the taller panel with standard 16:9 video takes cropping or stretching.
Side by side
BenQ RD280U vs ASUS ProArt PA279CRV: ASUS fits a conventional 16:9 workflow, while BenQ adds tall code space and KVM
Quick verdict
Both monitors run at 60Hz, so neither is a refresh-rate upgrade over the other. What separates them is screen shape and how you work. RD280U suits a desk where extra vertical room for code and a built-in KVM carry the everyday load. PA279CRV is the better match if you want a 16:9 4K workspace, documented Adobe RGB coverage or charging of up to 96W.
Before you buy
Why, and what it costs you
More rows only show up when text keeps the same scale
The 3840-pixel width is unchanged on RD280U, which adds 400 vertical pixels on top. With scaling and line height identical, that can fit more code or document content on screen without widening the editing pane.
Where this comes from
Subtracting 2160 from 2560 leaves 400 extra vertical pixels. The content benefit claimed here only holds if scaling and line height are equal.
The catch
ASUS ProArt Display 27-inch 4K
Same width, but 400 vertical pixels fewer.
BenQ RD Series 28-inch Programming Monitor
- Why pick it
- See more lines of a long code file on screen at the same scaling
- Run the same connected peripherals from two computers
- The catch
- Filling the taller panel with standard 16:9 video takes cropping or stretching.
ASUS ProArt Display 27-inch 4K
- Why pick it
- Use the whole panel for standard 16:9 4K material
- Work with the documented 99% Adobe RGB coverage
- The catch
- Same width, but 400 vertical pixels fewer.

In practice
Differences you will notice
More rows only show up when text keeps the same scale
The 3840-pixel width is unchanged on RD280U, which adds 400 vertical pixels on top. With scaling and line height identical, that can fit more code or document content on screen without widening the editing pane.
How we worked this out
Subtracting 2160 from 2560 leaves 400 extra vertical pixels. The content benefit claimed here only holds if scaling and line height are equal.
On the 3:2 panel, a full-width 16:9 frame leaves height unused
Shown uncropped, a 3840-by-2160 video frame spans the full width of RD280U and leaves 400 vertical pixels unused in total. The shape of that frame matches PA279CRV.
How we worked this out
Of RD280U's 2560 vertical pixels, a 16:9 frame uses 2160 and 400 are left over. That is 15.6% of the panel height, and a centered frame splits it between the bars.
Switching between two computers may be worth more than the extra charging watts
For a second host, RD280U provides a KVM and a separate USB-B data upstream path. It's the one to pick when a laptop and desktop need the same keyboard and mouse.
How we worked this out
How the KVM behaves depends on the video and USB paths of both hosts. The charging ceilings are 6W apart, which says nothing about whether either covers an unknown laptop workload.
Option A
BenQ, RD280U
RD Series 28-inch Programming Monitor
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.
- Best for
- See more lines of a long code file on screen at the same scaling
Facts we checked
- Native pixel grid and aspect: 3840 by 2560, 3:2
- Top refresh rate: 60Hz over DP or USB-C
- Laptop charging: Up to 90W by USB-C

Option B
ASUS, PA279CRV

Spec by spec
Where they really differ
| Spec | BenQ RD Series 28-inch Programming Monitor | ASUS ProArt Display 27-inch 4K | In practice |
|---|---|---|---|
| Native grid and shape | 3840 by 2560, 3:2 | 3840 by 2160, 16:9 | RD280U gives more vertical room but no extra horizontal source pixels. |
| Refresh ceiling | 60Hz over DP or USB-C | 60Hz | A high-refresh upgrade is not offered by either. |
| Laptop power | Up to 90W USB-C | Up to 96W USB-C | Whether you still need a separate adapter depends on the accepted power profiles and the workload. |
| Peripheral switching | Built-in KVM and USB-B upstream | USB hub without equivalent KVM documented | On ASUS, two hosts call for another accessory plan. |
| Published gamut coverage | 95% P3 | 99% Adobe RGB and 99% DCI-P3 | Go by the color space you need and ignore percentages that aren't comparable. |
Trade-offs
What each pick costs you
With BenQ RD Series 28-inch Programming Monitor
- Charging over USB-C stops at 90W.
With ASUS ProArt Display 27-inch 4K
- A comparable built-in KVM for two hosts is not documented.
Change of plan
When the answer changes
Priorities are more vertical room for code and a built-in KVM
Go with BenQ RD Series 28-inch Programming Monitor. Both the taller grid and the switching hardware come with RD280U.
Most of the work happens on a full-screen 16:9 4K canvas
Go with ASUS ProArt Display 27-inch 4K. PA279CRV is shaped to match, so no vertical area goes unused.
Decision guide
How to decide
Take RD280U if extra vertical room for code and a built-in KVM cover what the desk does every day. Take PA279CRV if you need a 16:9 4K canvas, documented Adobe RGB coverage or up to 96W charging. Refresh rate will not decide it, since both are 60Hz screens. You are picking a screen shape and a workflow.
More rows only show up when text keeps the same scale
RD280U gives you 400 extra vertical pixels at the same 3840-pixel width. Hold scaling and line height constant and that added height can display more code or document text without widening the editing pane. If you work in long files and the taller screen suits your viewing position, RD280U is the one to pick. If your work is mostly a standard 16:9 canvas, go with PA279CRV. Be aware that changing operating-system scaling can use up the extra space instead of revealing more lines.
On the 3:2 panel, a full-width 16:9 frame leaves height unused
Play an uncropped 3840-by-2160 video on the RD280U and it fills the width but wastes 400 vertical pixels in total. The PA279CRV has the same shape as that frame. Pick the ASUS if filling the screen with a standard 4K canvas matters more to you than extra document height. On the RD280U, the unused space during video is a reasonable cost for code work. It is neither a flaw nor a reason to stretch the picture.
Switching between two computers may be worth more than the extra charging watts
A second host gets its own path on RD280U, which has a KVM and a separate USB-B data upstream. That makes it the choice when a laptop and a desktop share a keyboard and mouse. PA279CRV supplies up to 96W instead of 90W, but that small gap only helps if the laptop accepts and needs the matching profile. On an ASUS desk with two hosts, you would still have to arrange your own peripheral switching.
What this page can’t tell you
- Nothing here is a measured improvement in eye comfort, productivity, color accuracy or pixel response. The workspace math assumes equal scaling.
