The catch
Dell 27 Plus 4K Monitor
This model is the S2725QS, which has no USB-C video. Do not confuse it with the S2725QC.
Side by side
Dell S2725QS vs U2723QE: S2725QS leans toward 120Hz motion, and UltraSharp takes the place of laptop docking accessories
Quick verdict
Go with the S2725QS if you want 120Hz 4K motion on a desktop setup. If your laptop desk needs USB-C charging, Ethernet and a KVM, the U2723QE is the fit.
Before you buy
Why, and what it costs you
Detail should be compared at the actual screen size
At about 163.2 pixels per inch, S2725QS matches the 163.2 of U2723QE. The 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. Inputs: 3840 × 2160 at 27 inches and 3840 × 2160 at 27 inches. These are approximate because the diagonals are published nominal values.
The catch
Dell UltraSharp 27 4K USB-C Hub Monitor
The upstream USB-C connection lacks Thunderbolt.

Pick the situations that sound like you
Run a desktop with its own peripherals
S2725QS gives 4K at up to 120 Hz with no USB-C video or charging. A desktop that has its own peripheral connections does not have to depend on a monitor dock.

Dock a laptop over USB-C
USB-C video and up to 90 W laptop power come with U2723QE. S2725QS has no such video-and-charge connection.

In practice
Differences you will notice
Detail should be compared at the actual screen size
At about 163.2 pixels per inch, S2725QS matches the 163.2 of U2723QE. The 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. Inputs: 3840 × 2160 at 27 inches and 3840 × 2160 at 27 inches. These are approximate because the diagonals are published nominal values.
Keep native detail apart from game speed
S2725QS draws 8.3 million native pixels per frame, and U2723QE 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.
A dock may end up on your shopping list with the QS suffix
U2723QE supplies a 90W USB-C hub, and S2725QS has no USB-C video or laptop charging.
How we worked this out
Exact records: S2725QS has usbCVideo false and usbCPowerW 0, while U2723QE has usbCVideo true and 90W.
Option A
Dell, S2725QS
27 Plus 4K Monitor
Sharp text, spreadsheets and relaxed gaming all sit comfortably on this 27-inch 4K screen with 120Hz refresh. It's meant for a desktop, or for a laptop that already has a dock.
- Best for
- Crisp desktop work and scrolling that runs smoother
Facts we checked
- 27-inch IPS panel, 3840 by 2160 at 120Hz
- Two HDMI inputs and DisplayPort 1.4, but no USB-C video
- Height adjustment spans 130 mm
Option B
Dell, U2723QE
UltraSharp 27 4K USB-C Hub Monitor
For a laptop that spends most days at a desk, the U2723QE offers a sharp 4K panel, Ethernet and a USB hub. If its 90-watt connection covers what your laptop needs, that matters more than a newer model number.
- Best for
- A wired 4K work desk served by one laptop cable
Facts we checked
- IPS Black panel at 60Hz, 27-inch, 3840 by 2160
- A USB-C video input that delivers up to 90 watts
- Gigabit Ethernet plus a DisplayPort output

Trade-offs
What each pick costs you
With Dell 27 Plus 4K Monitor
- The speakers don't make it a conferencing monitor with a webcam.
With Dell UltraSharp 27 4K USB-C Hub Monitor
- Scrolling is less fluid on a panel that tops out at 60Hz than on newer 120Hz UltraSharp models.
Decision guide
How to decide
The S2725QS suits 120Hz 4K motion on a desktop setup, whereas the U2723QE suits a laptop desk that needs USB-C charging, Ethernet and a KVM.
Leaving out USB-C alters the whole setup
USB-C video and charging are not provided by the S2725QS. A laptop buyer may need a separate dock, even though the screen resolution is the same as the U2723QE's.
The model with smoother motion isn't denser
Each panel is 27-inch 4K. The S2725QS doubles the maximum refresh rate, yet text density and native pixel count stay equal.
Hub features count only when they are connected
Ethernet, KVM capability and 90W delivery are what the U2723QE adds. They can simplify a desk, provided the computer and upstream cabling support the planned arrangement.
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.
