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
BenQ RD280U vs Dell U2724DE: BenQ puts more code on screen vertically, and Dell adds 120Hz and wired-network docking
Quick verdict
If you want a taller, denser coding canvas, choose the RD280U. For a Thunderbolt desk that puts smooth 120Hz motion and wired networking first, choose the U2724DE.
Before you buy
Why, and what it costs you
Detail should be compared at the actual screen size
U2724DE is 108.8 pixels per inch, while RD280U works out to about 163.7. A denser panel can draw finer text at the same logical size, and comfortable scaling is what determines workspace.
Where this comes from
Pixels per inch = √(width² + height²) / diagonal. The inputs used are 3840 × 2560 at 28.2 inches and 2560 × 1440 at 27 inches. Because diagonals are published nominal values, the figures are approximate.
The catch
Dell UltraSharp 27 Thunderbolt Hub Monitor
The native panel is QHD at up to 120Hz. Only a compatible host and cable let the Thunderbolt upstream carry video/data and up to 90W. Since the separate USB-C upstream is data only, HDMI/DP hosts also need their own video cable and the correct USB Selection. Auto KVM requires PBP Off, Auto Select On and Auto Select for Thunderbolt Yes. As for the USB Switch shortcut, it is PBP-only.

Work through a Thunderbolt hub
The Thunderbolt-centered hub and wired-networking arrangement come with U2724DE. Since both models list 90 W charging, that shared power ceiling does not decide the connection workflow.

In practice
Differences you will notice
Detail should be compared at the actual screen size
U2724DE is 108.8 pixels per inch, while RD280U works out to about 163.7. A denser panel can draw finer text at the same logical size, and comfortable scaling is what determines workspace.
How we worked this out
Pixels per inch = √(width² + height²) / diagonal. The inputs used are 3840 × 2560 at 28.2 inches and 2560 × 1440 at 27 inches. Because diagonals are published nominal values, the figures are approximate.
Keep native detail apart from game speed
RD280U draws 9.8 million native pixels per frame while U2724DE draws 3.7 million. The refresh ceilings are 60Hz and 120Hz respectively.
How we worked this out
Native pixels = width × height. Refresh interval =1000 / Hz, which gives 16.7 and 8.3 ms. These calculations concern signal and cadence and are not measured frame rates, input lag or pixel response.
Native vertical pixels run about 78% higher on BenQ
Both list 90W charging, and RD280U supplies 2560 rows versus U2724DE at 1440.
How we worked this out
(2560 / 1440 - 1) × 100 = 77.8%. That figure is pixel count and does not promise 78% more readable code after scaling.
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
- Long code files that you want to read without a wider screen
Facts we checked
- 28.2-inch IPS panel, 3840 by 2560, with a 3:2 aspect ratio
- Native refresh of up to 60Hz over DP or USB-C, or 50Hz over HDMI, and up to 90W from the video/data USB-C upstream
- 610.4 mm of chassis width and 244.5 mm of stand depth
- A built-in KVM and a USB-C MST display output
Option B
Dell, U2724DE
UltraSharp 27 Thunderbolt Hub Monitor
The Dell U2724DE is a 27-inch native QHD monitor that runs up to 120Hz. A verified Thunderbolt host gets video, data and up to 90W through the proper upstream port, while the separate USB-C upstream carries data only. To use RJ45 you need upstream data, the driver and an Ethernet cable, and DP Alt High Resolution limits USB data to 480 Mbps.
- Best for
- A desk for a compatible Thunderbolt laptop that needs QHD video, conditional charging and wired networking
Facts we checked
- 27-inch IPS Black panel, 2560 by 1440 at 120Hz
- Thunderbolt 4, with power delivery of up to 90 watts
- DisplayPort output, plus 2.5GbE networking
Spec by spec
Where they really differ
| Spec | BenQ RD Series 28-inch Programming Monitor | Dell UltraSharp 27 Thunderbolt Hub Monitor | In practice |
|---|---|---|---|
| Native resolution | 3840 × 2560 | 2560 × 1440 | Usable logical workspace changes with operating-system scaling. |
| Panel diagonal | 28.2 in | 27 in | The measured active diagonal may differ slightly from a nominal screen class. |
| Maximum refresh | 60Hz | 120Hz | Look at the exact input, resolution and overclock conditions. |
| Panel technology | IPS | IPS Black | A measured color or motion winner is not established by panel type alone. |
| Laptop power | Up to 90W | Up to 90W | For the desired delivery, the host, cable and negotiated power profile all have to support it. |
| Chassis width | 610.4 mm | Check exact drawing | Leave additional room for cables, arms and neighboring equipment. |
| Stand depth | 244.5 mm | Check exact drawing | More desk depth can be taken by the included stand than by the display cabinet. |
Trade-offs
What each pick costs you
With BenQ RD Series 28-inch Programming Monitor
- The 60Hz panel suits reading and development better than fast games.
With Dell UltraSharp 27 Thunderbolt Hub Monitor
- Using RJ45 takes upstream data, the correct Realtek driver and an Ethernet cable that you buy separately. Because DP Alt High Resolution can limit USB data to 480 Mbps, full 2.5GbE throughput is not promised. More-than-90W laptops need a supply of their own. Check the off-mode charging settings, and the 612.24 mm width and 192.28 mm stand depth.
Decision guide
How to decide
The RD280U is for a taller, denser coding canvas. The U2724DE is for a Thunderbolt desk where smooth 120Hz motion and wired networking take priority.
What fits vertically changes with the taller format
BenQ offers 2560 pixel rows to Dell's 1440. The real code-line gain depends on comfortable text scaling, but the native vertical headroom is substantial.
A typical USB-C work laptop can be charged by either
Both list up to 90W. Before assuming the laptop's original charger can stay in the bag, check its power requirement, especially under sustained load.
Dell gives up pixels and gets a faster desktop cadence
Twice BenQ's 60Hz, the U2724DE refreshes at 120Hz. Cursor and scrolling movement can feel smoother, but the number of pixels available for text does not improve.
What this page can’t tell you
- Calculated from published specifications, pixel density and refresh intervals say nothing measured about visual quality or latency.
- Think of the USB-C power number as a ceiling reached by negotiation. Full-speed charging is not promised for every laptop.
