Head-to-head

Dell S2722QC vs S2725QC: S2725QC doubles refresh without adding workspace or laptop charging power

The short answer

Choose the S2725QC for smoother scrolling and casual gaming. Choose the S2722QC when a better current offer makes 60Hz acceptable. Both provide 27-inch 4K resolution and up to 65-watt USB-C charging, so this is not a workspace or laptop-power upgrade.

Before you choose

The reasoning and the trade-offs

The refresh interval is halved

At the maximum setting the S2725QC has an 8.33 ms interval instead of 16.67 ms.

What this is based on

1000 ÷ 120 = 8.33 ms and 1000 ÷ 60 = 16.67 ms. This does not measure input lag or pixel response.

Main trade-off

Dell 27 4K USB-C Monitor

The screen refreshes at 60Hz rather than 120Hz.

Main trade-off

Dell 27 Plus 4K USB-C Monitor

Its 65-watt USB-C output may be short of what a power-hungry mobile workstation expects.

About this comparison

Compare Dell S2722QC and S2725QC for scrolling, laptop charging and work. The newer model doubles refresh, but keeps the same 4K workspace.

Is 120Hz worth replacing a 60Hz USB-C monitor

Winner by situation

Start with what you need it to do

  • Frequent scrolling and window movement

    120Hz offers shorter update intervals when the computer outputs the supported mode.

  • A mostly static document workflow

    A lower S2722QC offer can be reasonable if 60Hz already feels comfortable.

What matters in practice

The differences that matter

The refresh interval is halved

At the maximum setting the S2725QC has an 8.33 ms interval instead of 16.67 ms.

How we reached this conclusion

1000 ÷ 120 = 8.33 ms and 1000 ÷ 60 = 16.67 ms. This does not measure input lag or pixel response.

Your spreadsheet does not gain rows

At equal scaling both screens begin with the same 3840 by 2160 desktop.

How we reached this conclusion

Resolution and diagonal are unchanged. Refresh rate alters how often the picture updates, not how much it contains.

The charging limit is unchanged

A laptop that exceeds 65W remains outside the monitor's stated power ceiling with either model.

How we reached this conclusion

Both specify up to 65W USB-C power delivery. A newer model year does not raise that number.

Dell, S2722QC

27 4K USB-C Monitor

A 4K picture and 65-watt USB-C connection cover everyday laptop work without a separate dock for the display. It remains worth comparing when the current offer is meaningfully below a newer 120Hz model.

What you give up

Every choice has a cost

If you choose Dell 27 4K USB-C Monitor

  • A laptop that needs more than 65 watts may still need its own charger.

If you choose Dell 27 Plus 4K USB-C Monitor

  • The port selection is lighter than a full Thunderbolt dock.

What matters in practice

How to make the call

01

The useful upgrade is motion

The S2725QC can redraw the picture twice as often. That matters while scrolling, moving a pointer or playing a game at a compatible frame rate. It matters less when a document remains still for minutes at a time. The choice should follow how you use the screen rather than the age of the model.

02

Check the computer and dock before paying for 120Hz

The screen's 120Hz ceiling is only useful if the laptop, port, cable and any dock can deliver the desired mode. A connection that outputs 4K at 60Hz leaves much of the newer model's distinguishing benefit unused. Do not infer capability solely from a connector's shape.

03

An existing S2722QC is not suddenly short of detail

Both models display the same 4K desktop and offer 65-watt USB-C power. If your current S2722QC already solves text clarity and charging, upgrading is a preference for smoother movement. Compare that benefit with the current price difference and the cost of any required connection changes.

Check these before buying

  • Confirm 3840 by 2160 at 120Hz support across the entire connection chain.
  • Check current Amazon offers and exact model selection, especially on mixed-variation listings.

What this comparison cannot tell you

  • Speaker wattage is not a listening test.
  • Refresh interval is not input lag, response time or guaranteed game frame rate.
