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
A compatible USB-C laptop and a simpler one-cable desk call for the S2725QC. The S2725QS fits a desktop or an existing dock, particularly if you need full-size DisplayPort. Since both are 27-inch 4K 120Hz monitors, the last letter alters the connection more than the workspace.
Before you buy
A 163-PPI class picture and 8.29 million pixels come with both screens.
Where this comes from
At a 27-inch diagonal, each is 3840 × 2160. Identical measured panel performance is not established by equal specifications here.
The catch
This model is the S2725QS, which has no USB-C video. Do not confuse it with the S2725QC.
The catch
A power-hungry mobile workstation may want more than the 65-watt USB-C output delivers.

Each Dell monitor delivers 27-inch 4K at 120Hz. USB-C charging, DisplayPort and hub connections are what separate the QS from the QC.
Whether USB-C is needed for the same 4K 120Hz desk
Which one fits
In one cable, the QC can combine charging and video.
The direct DisplayPort input is on the QS.
Equipment you already own may be duplicated by the QC hub.
The target is above the QC's 65W maximum, and the QS has no laptop charging.
In practice
A 163-PPI class picture and 8.29 million pixels come with both screens.
At a 27-inch diagonal, each is 3840 × 2160. Identical measured panel performance is not established by equal specifications here.
Its upstream USB-C cable can carry video and charging together for a compatible laptop within 65W.
In its upstream port, the QC combines DisplayPort Alt Mode with up to 65W. The QS provides neither USB-C video nor power delivery.
Through the monitor, neither screen can stand in for a required 90W USB-C supply.
The QC tops out at 65W, 25W below 90W. The QS has no USB-C laptop-power output.

Spec by spec
| Spec | Dell 27 Plus 4K Monitor | Dell 27 Plus 4K USB-C Monitor | In practice |
|---|---|---|---|
| Panel format | 27-inch 3840 × 2160 IPS | 27-inch 3840 × 2160 IPS | Being in the same size and resolution class means the native desktop layout is the same. |
| Refresh ceiling | 120Hz | 120Hz | Adding USB-C brings no higher refresh tier. |
| USB-C video and power | No | Yes, up to 65W | This is the key difference for a laptop desk. |
| Full-size DisplayPort input | Yes | No | A desktop's existing DisplayPort cable can plug into the QS more directly. |
| HDMI inputs | Two | Two | Two HDMI sources fit on both. |
| USB peripheral hub | No | Yes | Keyboard and mouse connections can stay at the screen with the QC. |
| Stand depth | About 200 mm | About 200 mm | Decide on ports, and do not expect a meaningful stand-footprint difference. |
Trade-offs
Decision guide
The S2725QC is for a compatible USB-C laptop and a simpler one-cable desk, and the S2725QS is for a desktop or an existing dock, especially when you need full-size DisplayPort. Both being 27-inch 4K 120Hz monitors, the extra letter changes the connection more than the workspace.
In retailer listings it is easy to mix up the S2725QS and S2725QC. USB-C upstream and a USB hub come with the QC. Video input on the QS is more conventional and includes full-size DisplayPort. Make sure the exact model matches in the Amazon title and the selected variation.
The S2725QS may do everything you need if a desktop or dock already provides the right video connection. What makes the S2725QC more useful is replacing the daily cable handling for a laptop, and that benefit is concrete only if the laptop supports USB-C video and its charging needs fit the 65-watt ceiling.
Diagonal, resolution and maximum refresh specification are identical. Having a hub does not give the QC extra spreadsheet space. Buy it for a cleaner connection routine, and compare current offers without reading the suffix as a picture-quality ranking.
