Dell S2725DC vs Dell S2725QC
Same Dell family, same chassis, same single-cable USB-C convenience. The choice is resolution against refresh rate, and neither model is a step up from the other.
The S2725DC is the 1440p model at 144 Hz. At 27 inches that is 109 pixels per inch, a density that reads comfortably without display scaling, and a refresh rate that a mid-range graphics card can feed in games. It has a DisplayPort input alongside its HDMI and USB-C, and an 8-bit panel with no HDR claim.
The S2725QC is the 4K model at 120 Hz. Its 163 pixels per inch are noticeably sharper for text and photographs, it carries a 10-bit panel and an HDR10 badge, and it swaps the DisplayPort for a second HDMI, which suits a console or a second laptop better than a desktop tower. Driving 4K at that rate is a much bigger ask of a graphics card, and on a modest machine the practical refresh will be lower than the panel allows.
Neither is a gaming monitor in the strict sense, and both are sold on the USB-C: one cable carries video, data and laptop charging, which is the feature that defines the S27 line. The DC's DisplayPort is the one connectivity advantage a desktop owner should weigh, and the QC's second HDMI is the one a console owner should.
For a home office with a laptop, mixed document work and occasional games, the 1440p DC is the easier, cheaper, better-matched choice. For text-heavy work, photo editing, or a desk that wants the sharpest image and has the card or the patience to drive it, the 4K QC earns its premium. The HDR10 badge should not be part of the decision. At this brightness it is a label.
Editor’s note
Both of these are office monitors that happen to have a high refresh rate, and it is worth being clear about that before either is judged as a gaming display. Neither has local dimming, neither has a fast panel by gaming standards, and the refresh figures are a ceiling. They promise nothing about motion clarity.
The DC's extra refresh will mostly show in scrolling and window dragging if the laptop docked over that single cable is not driving competitive games, so its advantage is the one most likely to go unused.
The QC's sharper pixels are harder to design around, because they mean display scaling, and display scaling still produces inconsistent results in older Windows applications and in some professional software. Anyone moving up from a lower-density screen should expect an afternoon of adjustment before it feels like an improvement.
The buyer most likely to regret either is the one who chose on the HDR badge. Neither has the brightness or the dimming hardware to make HDR content look meaningfully different from a good standard picture, and one of the two wears a badge that suggests otherwise.
Head-to-head points: every spec is scaled between these products only, so a product can score high here and modestly on its own page, where the VS Score measures it against the median of its class.

What reviewers say
The bottom line
Decide this one on the machine, not on the monitor.
A laptop that will be docked and undocked daily, doing mixed work with some gaming, is better served by the cheaper model: its resolution needs no scaling, its refresh rate is easier to reach, and its DisplayPort input leaves the USB-C socket free for the laptop.
A desktop with a capable graphics card, or any desk where text and photographs are the day's work, justifies the sharper panel, and there the second HDMI is a bonus if a console shares the desk.
What should not decide it is the HDR badge. These are the same monitor with a couple of specs swapped, and the spec that matters describes what is plugged into the back.
