What matters
The S2725QS and S2725QC share the same 27-inch 4K 120Hz display baseline, so this is a connectivity decision. Keep the QS for physical DisplayPort and lower cost, or choose the QC when USB-C power and hub functions simplify a compatible laptop desk.
Key differences
- Both monitors share the compared panel, image, speaker, and stand baseline. Because resolution and refresh are unchanged, the QC premium cannot be justified as a visual upgrade.
- The S2725QS keeps physical DisplayPort and omits a USB hub. That is the simpler, cheaper fit for a desktop or a laptop desk that already has a dock.
- The S2725QC carries video, 5Gbps data, and up to 65W of power over USB-C while adding hub ports. That can remove a charger cable and separate hub only when the laptop supports the connection and fits the power limit.
Who it is for
- Buy the S2725QS if you use DisplayPort, already own a dock, or simply want the shared panel for less.
- Buy the S2725QC if a compatible laptop can use its USB-C display, power, and hub functions in place of equipment you would otherwise buy.
Watch-outs
- A laptop that draws more than 65W may still need its charger, and the QC hub does not replace Ethernet or every full-dock function.
- The QS price is promotional, so recheck both models at the same checkout before deciding.
- Do not choose the QC expecting higher image quality or refresh; the panel upgrade is not present.
