ASUS ROG Strix XG27ACS vs Dell S2725DSM: Which QHD Monitor Fits Your Setup?

Both are 27-inch 2560 x 1440 IPS monitors with stands that list height, tilt, pivot and swivel adjustment. Choose the ASUS if its DisplayPort/USB-C 180Hz ceiling or video-capable USB-C input fits your system; choose the Dell if 144Hz is enough and its built-in speakers are useful. These are specification-based fit notes, not comparative motion or image-quality test results.

The buying question

Should you prioritize the ASUS model’s higher published refresh ceiling and video-capable USB-C input, or the Dell’s built-in speakers and display setup features?

ASUS lists a 180Hz maximum over DisplayPort or USB-C and 7.5W USB-C power delivery; Dell lists 144Hz and two 3W speakers. Both manufacturers list height, tilt, pivot and swivel adjustment for their stands.

Quick verdict

Choose ASUS ROG Strix XG27ACS if

  • Your QHD-capable PC can use more than 144Hz over DisplayPort or USB-C, and the ASUS connection limits fit your system.
  • You want a USB-C input that carries DisplayPort video and understand its specified power delivery is 7.5W, not laptop-charging power.

Choose Dell 27 Plus QHD Monitor S2725DSM if

  • A 144Hz maximum is sufficient for your setup and Dell’s built-in two-speaker system is useful for basic desk audio.
  • You want Dell’s listed stand adjustments; ASUS also lists height, tilt, pivot and swivel, so compare the exact adjustment range for your desk.

When to skip: You need a 4K display rather than a 2560 x 1440 QHD monitor.
When the recommendation changes
  • If your source device only connects by HDMI, ASUS lists HDMI up to 144Hz, so its 180Hz ceiling does not apply to that connection.
  • If your laptop needs substantial USB-C power, do not treat the ASUS monitor’s 7.5W power delivery as a laptop charger or dock; plan a separate power source.
  • Both stands are listed with height, tilt, pivot and swivel adjustment; compare the exact range and desk fit if a particular position is essential.

The differences that matter

Gaming Refresh And Controls

ASUS ROG Strix XG27ACS

ROG Strix XG27ACS; 27-inch 2560x1440 Fast IPS, 180Hz maximum; DisplayPort and USB-C vertical signal frequency up to 180Hz, HDMI up to 144Hz; Adaptive-Sync, GamePlus, GameVisual and ELMB Sync listed.[1]

Dell 27 Plus QHD Monitor S2725DSM

Dell S2725DSM; 27-inch 2560x1440 IPS, 144Hz standard refresh rate; AMD FreeSync listed.[2]

What this changes: The higher ASUS ceiling matters only if the host and selected input can supply it; Dell's 144Hz ceiling may meet a buyer's target. These published specifications do not establish comparative motion or image quality.[1, 2]

The better fit depends on your priorities

Desk Placement And Device Setup

ASUS ROG Strix XG27ACS

XG27ACS stand lists height adjustment, tilt, swivel and pivot. It has USB-C DisplayPort Alt Mode with 7.5W power delivery.[1, 3]

Dell 27 Plus QHD Monitor S2725DSM

S2725DSM lists height, pivot, swivel and tilt stand adjustments and two built-in 3W speakers. Dell lists HDMI and DisplayPort; its product-page comparison table marks USB Type-C as not present.[2]

What this changes: Both stands list height, tilt, pivot and swivel. The distinct setup question is whether video over ASUS USB-C with 7.5W power delivery or Dell’s listed built-in speakers better fits the desk. The USB-C power figure is not a laptop-charging promise, and no audio-quality comparison was reviewed.[1, 3, 2]

The better fit depends on your priorities

Best for your routine

A QHD gaming PC can output above 144Hz and connects over DisplayPort or USB-C

Best fit: ASUS ROG Strix XG27ACS

Based on listed features, not comparative testing.

The ASUS model has the higher published 180Hz ceiling on those connections; the specifications do not establish superior measured motion or response.

You want built-in speakers for basic desk audio, and 144Hz is enough for your setup.

Best fit: Dell 27 Plus QHD Monitor S2725DSM

Based on listed features, not comparative testing.

Dell lists two built-in 3W speakers. Both products’ stands list height, tilt, pivot and swivel, so this recommendation is based on the speakers rather than an exclusive stand adjustment.

Your computer can send DisplayPort video over USB-C and you want one cable for the monitor video connection, with separate laptop power.

Best fit: ASUS ROG Strix XG27ACS

Based on listed features, not comparative testing.

ASUS lists USB-C DisplayPort Alt Mode and 7.5W power delivery. That supports a video connection but is not a promise of laptop charging or a full dock.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Whichever current offer costs more needs to earn that difference through a feature you will use, such as the ASUS refresh/USB-C fit or Dell stand/audio setup; compare the live offers at purchase time.

No suitable price-history window is available here, so this comparison does not make a buy-now or wait recommendation.

Limitations

  • This is a feature-fit comparison based on the manufacturers’ published specifications; Pickoryx did not conduct hands-on or controlled display testing.
  • The 180Hz maximum is connection-dependent: ASUS lists HDMI up to 144Hz, and the host GPU, cable and settings also affect the available signal mode.
  • ASUS specifies 7.5W USB-C power delivery. Do not assume it can replace a laptop power adapter or provide full docking functionality.
  • Both manufacturers list height, tilt, pivot and swivel adjustment for the stands. The pages do not establish a comparative winner for adjustment range or ergonomic fit.
  • Dell specifies two 3W speakers, but no comparative audio-quality testing was reviewed.
  • Live offer prices and a usable price-history window were not verified for this comparison.

Questions shoppers ask

Can the ASUS XG27ACS reach 180Hz over HDMI?

ASUS lists 180Hz over DisplayPort and USB-C, while its HDMI signal-frequency range tops out at 144Hz. The source device, cable and settings must also support the selected mode.

Can the ASUS USB-C port charge a laptop?

ASUS lists USB-C DisplayPort Alt Mode and 7.5W power delivery. Treat it as a video connection and do not assume that it replaces the laptop's charger or acts as a full dock.

Does the Dell S2725DSM include speakers?

Dell lists two built-in 3W speakers. This comparison does not assess their sound quality.

Can both monitors rotate to portrait orientation?

Both ASUS and Dell list pivot adjustment for their stands. Check each model’s exact adjustment range and your desk clearance if portrait positioning is essential.
