Main trade-off
Dell UltraSharp 32 4K Thunderbolt Hub Monitor
The 31.5-inch panel needs more desk width than the 27-inch UltraSharp.
Head-to-head
Dell U3225QE vs BenQ MA320U: Dell adds a 120Hz Thunderbolt hub, BenQ suits a 90W MacBook desk
The short answer
Choose U3225QE for 120Hz motion and a more capable Thunderbolt desk hub. MA320U suits a MacBook-focused workspace where 60Hz and 90W charging are enough.
Before you choose
The reasoning and the trade-offs
Compare detail at the actual screen size
U3225QE works out to about 139.9 pixels per inch, versus 139.9 for MA320U. Their pixel densities are close enough that layout and connection needs are stronger separators.
What this is based on
Pixels per inch = √(width² + height²) / diagonal. Inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Published nominal diagonals make these approximate.

Winner by situation
Start with what you need it to do
Use a high-power laptop and desk peripherals
U3225QE offers up to 140 W laptop power and a Thunderbolt-centered hub, compared with MA320U at 90 W. The laptop and cable must support the negotiated power profile.

Prefer Mac-focused controls
MA320U targets the MacBook-focused control workflow. Its 4K 60 Hz panel and 90 W power ceiling need to suit the intended Mac and connected accessories.

Want smoother 120Hz desktop motion
Dell reaches 120 Hz while BenQ stops at 60 Hz. The computer and selected connection must support the requested 4K timing.

- Not suitable
Need a straightforward 4K USB-C display
MA320U combines 4K resolution and up to 90 W USB-C charging. Dell has the same native resolution, so BenQ does not give up pixels when 60 Hz is sufficient.

What matters in practice
The differences that matter
Compare detail at the actual screen size
U3225QE works out to about 139.9 pixels per inch, versus 139.9 for MA320U. Their pixel densities are close enough that layout and connection needs are stronger separators.
How we reached this conclusion
Pixels per inch = √(width² + height²) / diagonal. Inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Published nominal diagonals make these approximate.
Separate native detail from game speed
U3225QE draws 8.3 million native pixels per frame and MA320U 8.3 million. Their refresh ceilings are 120Hz and 60Hz respectively.
How we reached this conclusion
Native pixels = width × height. Refresh interval =1000 / Hz, giving 8.3 and 16.7 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
Dell adds 50W of rated charging headroom
The stated USB-C power ceiling rises from 90W to 140W while resolution and diagonal stay equal.
How we reached this conclusion
140 - 90 = 50W. Both panels are 3840 × 2160 at 31.5 inches. Actual charging depends on negotiated host and cable support.

Meaningful differences
What changes the fit
| What changes | Dell UltraSharp 32 4K Thunderbolt Hub Monitor | BenQ MA Series 32-inch 4K Monitor for MacBook | Why it matters |
|---|---|---|---|
| Native resolution | 3840 × 2160 | 3840 × 2160 | Operating-system scaling changes usable logical workspace. |
| Panel diagonal | 31.5 in | 31.5 in | A nominal screen class may differ slightly from the measured active diagonal. |
| Maximum refresh | 120Hz | 60Hz | Check the exact input, resolution and overclock conditions. |
| Panel technology | IPS Black | IPS | Panel type alone does not establish a measured color or motion winner. |
| Laptop power | Up to 140W | Up to 90W | Host, cable and negotiated power profile must support the desired delivery. |
| Chassis width | 713.2 mm | 714.5 mm | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | 214.88 mm | 220.2 mm | The included stand can take more desk depth than the display cabinet. |
What you give up
Every choice has a cost
If you choose Dell UltraSharp 32 4K Thunderbolt Hub Monitor
- The 140-watt ceiling requires a compatible laptop and cable. It does not force every laptop to charge at that rate.
If you choose BenQ MA Series 32-inch 4K Monitor for MacBook
- Its 31.5-inch panel spreads the same 4K pixel count over more area than MA270U.
What matters in practice
How to make the call
The screen workspace is the same size
Both use 31.5-inch 3840 by 2160 panels. Dell does not add more pixels or a larger canvas, so the extra value needs to come from refresh rate and connectivity.
A charging ceiling is not a universal promise
Dell advertises up to 140W, BenQ 90W. The laptop, cable and negotiated power profile must support the offered level. A gaming laptop may still need its own charger.
The physical footprint is close
Widths are about 713 and 715 mm. Dell stand depth is about 215 mm against BenQ at 220 mm, so neither gives a dramatic desk-space saving.
What this comparison cannot tell you
- Pixel density and refresh intervals are calculations from published specifications, not a measured visual-quality or latency test.
- USB-C power is a maximum negotiated ceiling. It does not promise full-speed charging for every laptop.
