Dell U2724DE vs BenQ MA270U: With the same 90W charging, Dell leans toward motion and docking and BenQ adds 4K detail

Quick verdict

QHD at 120Hz, Thunderbolt 4 and integrated 2.5GbE are the U2724DE's draw. A denser 4K image and built-in speakers at 60Hz are the MA270U's. Up to 90W of laptop power delivery is advertised for both.

Before you buy

Why, and what it costs you

Native pixels are 2.25 times as many on BenQ in the same size class

Someone who prefers higher-density rendering benefits from that, but it does not automatically provide 2.25 times the usable workspace after operating-system scaling.

Where this comes from

(3840 × 2160) / (2560 × 1440) = 2.25. Each is specified as a 27-inch, 16:9 monitor.

The catch

What this page compares

On a 27-inch laptop desk, U2724DE and MA270U split between QHD at 120Hz with network docking and 4K at 60Hz with built-in speakers.

QHD at 120Hz, Thunderbolt 4 and integrated 2.5GbE are the U2724DE's draw. A denser 4K image and built-in speakers at 60Hz are the MA270U's. Up to 90W of laptop power delivery is advertised for both.

In practice

Differences you will notice

Native pixels are 2.25 times as many on BenQ in the same size class

Someone who prefers higher-density rendering benefits from that, but it does not automatically provide 2.25 times the usable workspace after operating-system scaling.

How we worked this out

(3840 × 2160) / (2560 × 1440) = 2.25. Each is specified as a 27-inch, 16:9 monitor.

The refresh ceiling doubles on Dell with no 4K rendering required

On Dell a source can target QHD at 120Hz, and on BenQ it can target 4K at 60Hz. What this comes down to is detail versus refresh and not a single speed ranking.

How we worked this out

Dell: 2560 × 1440 at 120Hz. BenQ: 3840 × 2160 at 60Hz. Refresh is 120 / 60 = 2, while native pixels differ by 2.25 times.

This pair is not decided by the charging ceiling

Up to 90W to the laptop is advertised by both. A requirement for a guaranteed 100W monitor output falls outside both specifications, whatever the resolution or Thunderbolt.

How we worked this out

90W = 90W. Each ceiling is exceeded by 10W by a 100W output requirement. Actual negotiated power can be lower.

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.

Trade-offs

  • Built-in speakers are missing.

With BenQ MA Series 27-inch 4K Monitor for MacBook

  • Its listed ports include no built-in Ethernet connection.

Change of plan

When the answer changes

Native 4K is non-negotiable

Go with BenQ MA Series 27-inch 4K Monitor for MacBook. Up to 60Hz at 3840 × 2160 is what MA270U supplies.

Either integrated Ethernet or native 120Hz has to be there

Go with Dell UltraSharp 27 Thunderbolt Hub Monitor. U2724DE brings 2.5GbE along with QHD at up to 120Hz.

Native 4K and 120Hz are both required

Neither model fits. BenQ's 4K refresh ceiling is 60Hz, and Dell is QHD.

Decision guide

How to decide

The U2724DE is for QHD at 120Hz, Thunderbolt 4 and integrated 2.5GbE. The MA270U is for a denser 4K image and built-in speakers at 60Hz. Both advertise up to 90W laptop power delivery.

01

Judge the image trade-off from your normal viewing distance

More native pixels come from the BenQ panel and a higher refresh ceiling from the Dell. Try 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.

02

Treat the dock and the display separately

Thunderbolt, RJ45 and multiple downstream connections come with the U2724DE, and they can replace specific external connections on a laptop desk. BenQ's built-in audio addresses a different need. Before deciding which extra hardware is required, list the devices that must stay plugged in.

03

Thunderbolt does not imply a charging advantage

A 90W maximum for laptop power delivery is specified for both. What gets used is negotiated by the actual computer and cable. If a workload needs more, verify the laptop's external-charger behavior and don't treat Thunderbolt as a promise of more power.

Check these before you buy

  • Check that the laptop, operating system and chosen cable all support the native resolution and refresh rate you want.
  • List the Ethernet, audio and charging connections you need, and measure the stand position that works for you.

What this page can’t tell you

  • We did no visual-quality, ergonomic, response-time or speaker testing. After the US catalog URL redirected, the Dell hardware specifications were rechecked on its current official UK model page.
