The catch
Dell 27 4K USB-C Monitor
Refresh tops out at 60Hz instead of 120Hz.
Side by side
Dell S2722QC vs S2725QC: S2725QC doubles the refresh rate and adds no workspace or laptop charging power
Quick verdict
Smoother scrolling and casual gaming point to the S2725QC. The S2722QC makes sense when a better current offer makes 60Hz acceptable. Both give you 27-inch 4K resolution and up to 65-watt USB-C charging, so moving up improves neither workspace nor laptop power.
Before you buy
Why, and what it costs you
The time between refreshes is halved
At its maximum setting, the S2725QC has an interval of 8.33 ms, not 16.67 ms.
Where this comes from
1000 ÷ 120 = 8.33 ms and 1000 ÷ 60 = 16.67 ms. Neither input lag nor pixel response is measured by this.
The catch
Dell 27 Plus 4K USB-C Monitor
A power-hungry mobile workstation may want more than the 65-watt USB-C output delivers.
Dell 27 4K USB-C Monitor
- Why pick it
- Your day is mostly static documents, and the offer is meaningfully lower.
- Having the S2722QC already, you are happy with 60Hz.
- The catch
- Refresh tops out at 60Hz instead of 120Hz.
Dell 27 Plus 4K USB-C Monitor
- Why pick it
- Motion stands out to you when you scroll and move windows.
- Up to 120Hz appeals to you, as long as the one-cable 4K format stays.
- The catch
- A power-hungry mobile workstation may want more than the 65-watt USB-C output delivers.

Pick the situations that sound like you
Scrolling and moving windows often
When the computer outputs the supported mode, 120Hz offers shorter update intervals.

A workflow of mostly static documents
If 60Hz already feels comfortable, a lower S2722QC offer can be reasonable.

Differences you will notice
The time between refreshes is halved
At its maximum setting, the S2725QC has an interval of 8.33 ms, not 16.67 ms.
How we worked this out
1000 ÷ 120 = 8.33 ms and 1000 ÷ 60 = 16.67 ms. Neither input lag nor pixel response is measured by this.
No extra rows appear in your spreadsheet
With equal scaling, the same 3840 by 2160 desktop is where both screens begin.
How we worked this out
Neither resolution nor diagonal changes. Refresh rate affects how often the picture updates and not how much it contains.
The charging limit stays the same
With either model, a laptop that exceeds 65W stays outside the monitor's stated power ceiling.
How we worked this out
Up to 65W of USB-C power delivery is specified for both. That number is not raised by a newer model year.
Option A

27 4K USB-C Monitor

Trade-offs
What each pick costs you
With Dell 27 4K USB-C Monitor
- Its own charger may still be needed by a laptop that draws more than 65 watts.
With Dell 27 Plus 4K USB-C Monitor
- You get fewer ports than a full Thunderbolt dock would give you.
Decision guide
How to decide
The S2725QC suits smoother scrolling and casual gaming. The S2722QC is the choice when a better current offer makes 60Hz acceptable. Because both provide 27-inch 4K resolution and up to 65-watt USB-C charging, moving between them is not a workspace or laptop-power upgrade.
Motion is the upgrade that counts
Twice as many redraws of the picture are possible on the S2725QC. That counts when you scroll, move a pointer or play a game at a compatible frame rate, and counts for less while a document sits still for minutes. Let how you use the screen drive the choice. The age of the model should not.
Before paying for 120Hz, check the computer and dock
Only if the laptop, port, cable and any dock can deliver the mode you want is the screen's 120Hz ceiling of any use. A connection that outputs 4K at 60Hz leaves much of what sets the newer model apart unused. Don't judge capability from a connector's shape alone.
Owning an S2722QC doesn't leave you short on detail
The same 4K desktop and 65-watt USB-C power come with either model. When your current S2722QC already takes care of text clarity and charging, upgrading comes down to a taste for smoother movement. Weigh that benefit against the current price difference and the cost of any connection changes you would need.
What this page can’t tell you
- Speaker wattage does not replace a listening test.
- Input lag, response time and guaranteed game frame rate are not what a refresh interval tells you.
