The catch
Dell UltraSharp 32 4K Thunderbolt Hub Monitor
Compared with the 27-inch UltraSharp, the 31.5-inch panel takes up more desk width.
Side by side
Dell U3225QE vs BenQ PD3205U: BenQ’s 90W ceiling is exceeded on Dell, which also adds smoother motion
Quick verdict
Go with the U3225QE if you want 120Hz motion, Thunderbolt and higher-power charging. If your 60Hz creative desk already meets the 90W power budget, the PD3205U suits it.
Before you buy
Why, and what it costs you
Detail should be compared at the actual screen size
About 139.9 pixels per inch is what U3225QE works out to, and PD3205U is at 139.9 too. Pixel densities are close enough that layout and connection needs do more to separate them.
Where this comes from
Pixels per inch = √(width² + height²) / diagonal. The inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Because the diagonals are published nominal values, these figures are approximate.

What this page compares
120Hz motion, Thunderbolt and higher-power charging make the case for the U3225QE. The PD3205U suits a 60Hz creative desk that already meets its 90W power budget.

Pick the situations that sound like you
Build the desk around Thunderbolt
The Thunderbolt-centered hub and up to 140 W laptop power come with U3225QE. PD3205U's USB-C arrangement is rated to 90 W.

Do design work at 60Hz
At 60 Hz, PD3205U offers a 31.5-inch 4K image. Dell shares that native canvas and adds 120 Hz, which is unnecessary if the selected workflow stays at 60 Hz.

Prefer 4K at 120Hz
While PD3205U stops at 60 Hz, U3225QE reaches 120 Hz at 4K. The desired timing has to be supported by the host and cable.

In practice
Differences you will notice
Detail should be compared at the actual screen size
About 139.9 pixels per inch is what U3225QE works out to, and PD3205U is at 139.9 too. Pixel densities are close enough that layout and connection needs do more to separate them.
How we worked this out
Pixels per inch = √(width² + height²) / diagonal. The inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Because the diagonals are published nominal values, these figures are approximate.
Keep native detail apart from game speed
U3225QE draws 8.3 million native pixels per frame, and PD3205U also draws 8.3 million. Refresh ceilings are 120Hz and 60Hz respectively.
How we worked this out
Native pixels = width × height. Refresh interval =1000 / Hz, which gives 8.3 and 16.7 ms. These calculations concern signal and cadence and are not measured frame rates, input lag or pixel response.
About 42 mm of desk depth is saved by the Dell stand
Compared with BenQ at 256.8 mm, the 214.88 mm stand is 41.92 mm shallower, and panel size and resolution are the same.
How we worked this out
256.8 - 214.88 = 41.92 mm. Viewing distance is not the same thing as outer stand depth.
Option A
Dell, U3225QE
UltraSharp 32 4K Thunderbolt Hub Monitor
On a desk where you want fewer separate boxes, this larger 4K work screen offers 120Hz scrolling, 140-watt charging and a Thunderbolt hub.

Spec by spec
Where they really differ
| Spec | Dell UltraSharp 32 4K Thunderbolt Hub Monitor | BenQ DesignVue 32-inch 4K USB-C | In practice |
|---|---|---|---|
| Native resolution | 3840 × 2160 | 3840 × 2160 | Usable logical workspace changes with operating-system scaling. |
| Panel diagonal | 31.5 in | 31.5 in | The measured active diagonal may differ slightly from a nominal screen class. |
| Maximum refresh | 120Hz | 60Hz | Look at the exact input, resolution and overclock conditions. |
| Panel technology | IPS Black | IPS | A measured color or motion winner is not established by panel type alone. |
| Laptop power | Up to 140W | Up to 90W | For the desired delivery, the host, cable and negotiated power profile all have to support it. |
| Chassis width | 713.2 mm | 714.7 mm | Leave additional room for cables, arms and neighboring equipment. |
| Stand depth | 214.88 mm | 256.8 mm | More desk depth can be taken by the included stand than by the display cabinet. |
Trade-offs
What each pick costs you
With Dell UltraSharp 32 4K Thunderbolt Hub Monitor
- A laptop and cable that support it are needed to reach the 140-watt ceiling, and not every laptop will charge at that rate.
With BenQ DesignVue 32-inch 4K USB-C
- Don't mistake its 99 percent sRGB specification for the wider DCI-P3 coverage of other DesignVue models.
Decision guide
How to decide
The U3225QE is for 120Hz motion, Thunderbolt and higher-power charging. The PD3205U is for a 60Hz creative desk that already meets its 90W power budget.
The workspace doesn't change
31.5-inch 4K displays, both of them. At equal scaling the Dell gives no larger workspace, even though it is the more capable hub.
Dell gets a measurable space benefit from its stand
Depth is about 214.9 mm on the U3225QE and 256.8 mm on the PD3205U. On a shallow desk, that can leave more room for a keyboard.
The upgrade has to be justified by power and connection
Whether 140W versus 90W matters depends on the laptop accepting and needing the higher profile. Confirm that the host supports the Thunderbolt display mode and cable you want.
What this page can’t tell you
- These pixel density and refresh interval figures are calculated from published specifications and do not come from a measured visual-quality or latency test.
- The USB-C power figure is the highest level that can be negotiated. It does not guarantee full-speed charging for every laptop.
