Main trade-off
Dell UltraSharp 27 Thunderbolt Hub Monitor
Its native resolution is QHD rather than 4K.
Head-to-head
Dell U2724DE vs BenQ MA270U: Same 90W charging, Dell favors motion and docking while BenQ adds 4K detail
The short answer
Choose U2724DE for QHD at 120Hz, Thunderbolt 4 and integrated 2.5GbE. Choose MA270U for a denser 4K image and built-in speakers at 60Hz. Both advertise up to 90W laptop power delivery.
Before you choose
The reasoning and the trade-offs
BenQ packs 2.25 times as many native pixels into the same size class
That favors a higher-density rendering preference. It does not automatically provide 2.25 times the usable workspace after operating-system scaling.
What this is based on
(3840 × 2160) / (2560 × 1440) = 2.25. Both are specified as 27-inch, 16:9 monitors.

Winner by situation
Start with what you need it to do
I need a network-connected Thunderbolt desk
Dell combines Thunderbolt 4 with 2.5GbE. BenQ has USB-C video and no listed RJ45 connection.

What matters in practice
The differences that matter
BenQ packs 2.25 times as many native pixels into the same size class
That favors a higher-density rendering preference. It does not automatically provide 2.25 times the usable workspace after operating-system scaling.
How we reached this conclusion
(3840 × 2160) / (2560 × 1440) = 2.25. Both are specified as 27-inch, 16:9 monitors.
Dell doubles the refresh ceiling without requiring 4K rendering
A source can target QHD at 120Hz on Dell or 4K at 60Hz on BenQ. This is a detail-versus-refresh decision rather than a single speed ranking.
How we reached this conclusion
Dell: 2560 × 1440 at 120Hz. BenQ: 3840 × 2160 at 60Hz. 120 / 60 = 2, while native pixels differ by 2.25 times.
The charging ceiling does not decide this pair
Both advertise up to 90W to the laptop. A requirement for a guaranteed 100W monitor output is outside both specifications, regardless of resolution or Thunderbolt.
How we reached this conclusion
90W = 90W. A 100W output requirement exceeds each ceiling by 10W. Actual negotiated power can be lower.
Choice A
Dell, U2724DE
UltraSharp 27 Thunderbolt Hub Monitor
Dell U2724DE is a 27-inch native QHD monitor up to 120Hz. A verified Thunderbolt host can use video, data and up to 90W through its proper upstream. Separate USB-C upstream is data only. RJ45 needs upstream data, driver and Ethernet cable, with DP Alt High Resolution limiting USB data to 480 Mbps.
- Best matched use
- A compatible Thunderbolt laptop desk with QHD video, conditional charging and wired networking
Checked facts
- Native resolution: 2560 × 1440
- Maximum native refresh rate: 120Hz
- Laptop video connection: Thunderbolt 4
- Integrated Ethernet: 2.5GbE RJ45
Choice B
BenQ, MA270U
MA Series 27-inch 4K Monitor for MacBook
A 4K matte screen centers its controls and color modes on MacBook use, with one 90W USB-C video input and a separate downstream USB-C accessory port.
- Best matched use
- A simple MacBook desk with familiar brightness controls
Checked facts
- Native resolution: 3840 × 2160
- Maximum native refresh rate: 60Hz
- Laptop video connection: USB-C DisplayPort Alt Mode
- Integrated Ethernet: No Ethernet port in the listed connections
Meaningful differences
What changes the fit
| What changes | Dell UltraSharp 27 Thunderbolt Hub Monitor | BenQ MA Series 27-inch 4K Monitor for MacBook | Why it matters |
|---|---|---|---|
| Native resolution | 2560 × 1440 | 3840 × 2160 | BenQ has more addressable pixels in the same 27-inch screen class. OS scaling controls usable workspace and text size. |
| Maximum native refresh rate | 120Hz | 60Hz | Dell has the higher refresh ceiling. Neither specification is a measured response-time result. |
| Laptop video connection | Thunderbolt 4 | USB-C DisplayPort Alt Mode | Thunderbolt and ordinary USB-C video are different capabilities. Confirm what the laptop supplies. |
| Integrated Ethernet | 2.5GbE RJ45 | No Ethernet port in the listed connections | Dell can take the monitor's network-dock role. BenQ needs an extra adapter for wired networking. |
| Built-in speakers | None | Two 3W speakers | BenQ provides basic sound without adding another speaker. Dell needs an external audio device. |
| Stand height adjustment | 150mm | 115mm | Dell offers 35mm more vertical travel. Measure the actual seated eye position and desk height. |
What you give up
Every choice has a cost
If you choose Dell UltraSharp 27 Thunderbolt Hub Monitor
- It has no built-in speakers.
If you choose BenQ MA Series 27-inch 4K Monitor for MacBook
- There is no built-in Ethernet connection in its listed ports.
Recommendation switch
The decision flips if...
Native 4K is a firm requirement
Choose BenQ MA Series 27-inch 4K Monitor for MacBook. MA270U supplies 3840 × 2160 at up to 60Hz.
Integrated Ethernet or native 120Hz is essential
Choose Dell UltraSharp 27 Thunderbolt Hub Monitor. U2724DE supplies 2.5GbE and QHD at up to 120Hz.
You require both native 4K and 120Hz
Choose neither. Dell is QHD and BenQ's 4K refresh ceiling is 60Hz.
What matters in practice
How to make the call
Pick the image trade-off at your normal viewing distance
The BenQ panel provides more native pixels, while Dell provides a higher refresh ceiling. Check the operating system's scaling choices with the applications you use. Neither pixel count nor a refresh specification proves measured sharpness, motion clarity or comfort.
Separate the dock from the display
U2724DE includes Thunderbolt, RJ45 and multiple downstream connections. That can replace specific external connections in a laptop desk. BenQ's built-in audio solves a different need. List the devices that must remain plugged in before deciding which extra hardware is required.
Do not infer a charging advantage from Thunderbolt
Both specify a 90W maximum for laptop power delivery. The actual computer and cable negotiate what is used. If a workload needs more, verify the laptop's external-charger behavior instead of treating Thunderbolt as a promise of more power.
What this comparison cannot tell you
- No visual-quality, ergonomic, response-time or speaker testing was performed. The Dell hardware specifications were rechecked on its current official UK model page after the US catalog URL redirected.
