Compare Dell S2725QS vs Dell Alienware AW3425DWM

Changes between some image-scaling modes are unusually quick and convenient.

The simple interface and quick-access controls make shifting between gaming and desk work straightforward.

No integrated hub means keyboard, mouse and storage accessories must connect to a PC or a separate dock.

Two easy-to-reach USB-A ports provide handy peripheral passthrough when connected upstream to the PC.

A detailed test found no distracting variable-refresh flicker, a welcome advantage over some competing display technologies.

Dark scenes with shifting frame rates can produce conspicuous brightness fluctuations, although some testers rarely noticed the problem in play.

The IPS panel maintains colors and detail impressively off-center, making it comfortable to view from different desk positions.

Colors and brightness fade noticeably off center, making the screen best used directly in front of the curve.

The stand offers plenty of adjustment but can wobble, especially compared with the preceding Dell model.

The flat base supports the big screen securely with very little wobble when the desk is bumped.

Dark scenes suffer from grayish blacks and IPS glow rather than OLED-like depth, even though contrast is acceptable by budget IPS standards.

Deep SDR blacks are a signature benefit of this VA screen, especially compared with conventional IPS panels.

Monitor speakers are a convenient extra for games, calls, and videos. Reactions range from pleasantly surprised by their bass to complaints that they sound loud and muddy.

There are no integrated speakers, disappointing anyone hoping to play audio without headphones or separate speakers.

Fast is preferable around 120Hz and Normal often works better at 60Hz; the Extreme setting adds obvious overshoot without enough improvement.

Conservative presets keep overshoot modest, though faster options only partly tackle blur and may introduce inverse ghosting.

Measured pixel transitions are middling or slow for 120Hz and give moving objects more blur than faster gaming monitors.

Most gaming feels responsive, but dark pixel transitions are too slow to deliver consistently clean 180Hz motion.

Two HDMI ports and DisplayPort cover conventional hookups, but no USB-C, USB hub or headphone jack is a recurring inconvenience.

Two HDMI inputs, DisplayPort and a small USB-A hub cover essential devices, but USB-C and audio output are missing.

HDMI 2.1 bandwidth and 4K/120Hz support suit modern consoles, although a test noted that Xbox 1440p at 120Hz is not supported.

Modern PlayStation and Xbox signals generally work, but native 21:9 output is absent, leaving black bars and wasting screen width.

IPS brings consistent colors and broad viewing angles, but does not deliver the deep blacks of OLED or VA alternatives.

Its VA LCD gives deep blacks, good SDR brightness and no OLED burn-in risk, in exchange for narrower angles and slower dark transitions.

HDR game and movie presets can add excessive saturation or sharpening rather than improving natural image quality.

There is a useful collection of gaming options, but some specialized presets distort the image more than they help.

Low input lag helps, but sluggish pixel transitions and visible blur make this weaker than a properly tuned gaming monitor for esports.

Low input lag helps in competitive titles, but dark smearing and relatively slow pixel transitions hold it back for motion-focused players.

120Hz movement feels smoother than 60Hz, but many fast transitions still carry powdery blur and overshoot that gaming monitors handle better.

Camera pans look smoother at high refresh, but dark transitions remain considerably blurrier than on good IPS or OLED displays.

A rear cover, clip, and simple cable routing help tidy the desk; some laptop setups still require awkward extra adapters or docks.

The stand's cable-routing opening and conveniently placed hub help keep keyboard, mouse and video wiring tidy.

Colors remain impressively consistent across much of the panel, with only minor changes at the edges on the detailed test unit.

Typical casual use looks reasonably even, but brightness falloff and color uniformity limitations discourage professional editing.

The clean finish and reinforced stand can feel upscale for the price, although the largely plastic build and slight wobble are reminders of its budget positioning.

A polished chassis, clean styling and sturdy stand make the monitor look and feel more expensive than it is.

Its light matte coating softens everyday reflections, but direct sunlight can still produce strong glare and a glossy-looking patch.

The matte coating diffuses some glare, but strong light sources can spread across the curved screen and impair visibility.

PC games benefit from a smooth 120Hz signal and low lag, but image smear and slow transitions make the experience less polished than dedicated gaming screens.

A wide 180Hz canvas with low lag is enjoyable for mainstream PC play; demanding competitive players may notice smearing.

120Hz is a substantial everyday upgrade for scrolling, window movement and casual play, even though panel response cannot always keep up.

A 180Hz ceiling gives fluid gaming and plenty of headroom, though the VA panel cannot fully keep up with every transition.

At 27 inches, the 4K pixel density makes text and images exceptionally crisp and allows detailed desktop work.

The 3440×1440 format looks detailed enough for gaming and text, without the extra sharpness of a full 4K screen.

Coverage is good for sRGB but falls short of a full professional wide gamut, with some welcome extra vibrancy in standard desktop content.

Broad DCI-P3 and sRGB coverage produces punchy color and gives the panel more range than many entry-level displays.

Fast camera movement and high-contrast edges leave noticeable trailing, especially compared with gaming-focused IPS displays.

Visible dark trailing is the most persistent weakness, particularly in rapid high-refresh scenes and against dark backgrounds.

One detailed test unit showed only minor clouding and bleed, although sample variation remains a consideration.

A little leakage can appear at the edges or off-axis, although it was not considered distracting in normal centered use.

Detailed 4K visuals work nicely in slower-paced solo games, but weak HDR and moving-image blur reduce the cinematic effect.

The panoramic view, curve and deep SDR blacks make story-driven and open-world games particularly engaging.

Most verdicts strongly recommend it as an affordable all-round work monitor, with reservations about USB-C, speakers and serious gaming.

The overall verdict favors affordable, immersive gaming over premium image fidelity, with strong praise for value and repeated motion/HDR caveats.

Height, tilt and swivel adjustments are useful and generally smooth, although portrait clearance and occasional wobble limit the experience.

Height and tilt are useful, while reports differ over swivel capability; portrait rotation is not available on the stock stand.

Small lettering, interface elements and fine photo detail look impressively crisp thanks to the 4K pixel density.

Text and ordinary desktop content remain pleasantly crisp at 3440×1440, even if the panel is not 4K-sharp.

FreeSync and compatible VRR reduce tearing and improve gameplay smoothness, but overshoot can worsen as the refresh rate falls.

Support for common variable-refresh formats is useful, although some experiences highlight compatibility caveats or unwanted flicker.

Inputs feel responsive and measured signal delay is low, although pixel blur can still make motion look less crisp than the controls feel.

Low processing latency makes controls feel immediate across refresh rates, even if the panel's pixel transitions lag behind.

The strongest combination is sharp work output plus smooth casual gaming and media, rather than excellence at high-end HDR or competitive gaming.

The wide uninterrupted work area fits several windows or a lengthy timeline, making this more than a gaming-only display.

The 27-inch panel and compact stand offer useful working space without overpowering a typical desk.

The wide panel needs lateral space, but its unusually compact, flat stand leaves a surprisingly usable desk surface.

The mild matte finish controls glare without much visible grain, although sensitive users may see slight mistiness or diminished vibrancy.

The matte surface maintains generally good clarity, but glossy premium OLED alternatives can look cleaner.

The standard 16:9 format suits everyday software and video, though it cannot provide the horizontal space of an ultrawide.

The expansive 21:9 view adds space and immersion, though unsupported games and applications can show black bars.

Lower-than-native resolutions remain usable and can be sharpened, although QHD monitor-side scaling is limited to 60Hz and looks softer than 4K.

Console 4K signals can be downscaled for more detail at 60Hz, but the panel does not provide native ultrawide console output.

It cannot charge a laptop through a USB-C display cable, so laptop owners need separate power and possibly a dock.

No USB-C power delivery is available, so charging a laptop requires a separate power connection.

One reported ownership account describes multiple unit failures, so checking operation and the return period is sensible despite the otherwise positive value picture.

The absence of OLED burn-in vulnerability is a meaningful upside for users who leave static desktop elements visible.

Tool-free assembly and straightforward stand attachment make getting started uncomplicated, even with an extra stand piece.

Initial picture adjustments are uncomplicated, including a quick fix for unwanted automatic brightness changes.

The HDMI inputs are a valuable upgrade over older Dell models, enabling higher-bandwidth 4K/120Hz gaming signals on compatible hardware.

Full-bandwidth HDMI 2.1 is unusually welcome at this price and avoids older HDMI refresh-rate restrictions.

Its sharp 4K/120Hz display and adjustable stand are excellent value at typical sale prices, especially for buyers who will not miss USB-C.

The mix of size, 180Hz speed, deep blacks and solid construction is compelling at its budget price, if HDR and crystal-clear motion are not essential.

Most testers liked the factory sRGB presentation and measured low color error, although some owners encountered a green cast or needed adjustments.

Factory grayscale and the dedicated sRGB mode are generally respectable, although white balance, gamma and uniformity are not rigorous enough for every professional task.

Static contrast is decent for ordinary IPS and can add some depth, but gray blacks and glow stop dark scenes from looking genuinely rich.

High native VA contrast makes dark SDR scenes convincing. The advantage does not carry over into convincing HDR local dimming.

HDR disables the dark-stabilizer adjustment, reducing control over shadow visibility when HDR is active.

Brightening dark detail may make shadowed areas easier to read, at the expense of the panel's natural contrast.

DisplayPort works for high-refresh output, but one tester needed to correct Nvidia’s default limited-range RGB setting.

DisplayPort supports the full ultrawide refresh specification, although high-bit-depth 180Hz operation can require DSC.

SDR brightness is generally strong for the price with a useful adjustment range; it is far less impressive as HDR peak brightness.

SDR output is strong for the price, with useful adjustment range. HDR highlights are much less impressive, and measured brightness varies between units.

A rear joystick provides a convenient way to navigate picture and other settings.

The joystick and accessible menus make it easy to reach picture controls, with a good range of options to customize.

The crisp, colorful SDR picture is a major strength, while weak dark-room contrast and HDR hold it back from premium image quality.

Strong SDR contrast, vivid color and decent brightness produce an appealing picture for the price; HDR is a clear step down.

FreeSync and compatible variable-refresh operation reduce tearing and improve smoothness, though changing refresh rates expose limitations in pixel-response tuning.

Variable refresh reduces tearing and stays reasonably consistent across refresh rates. It can also worsen smearing and flicker when frame rates fluctuate.

Most testers found HDR weak, with limited luminance, gray blacks and no local dimming; a more positive review liked the added brightness and contrast effect.

HDR is repeatedly criticized for weak highlights, elevated blacks and intrusive local dimming; SDR is the safer choice.

Lack of local dimming prevents HDR from separating small highlights from dark surroundings and leaves blacks looking gray.

Only eight edge-lit zones are used in HDR, producing elevated blacks and blooming with no option to disable the effect in that mode.

The light-colored chassis and metal-reinforced parts feel reasonably solid, but some testers noticed wobble and less substantial materials than older models.

Solid construction and neat finishing give the affordable monitor a more premium impression, with few obvious physical flaws.

Slim bezels and a clean ash-white finish are widely appreciated, giving the monitor a more polished look than many low-cost office screens.

A clean blue-black Alienware design, understated branding and compact flat base look more polished than the price suggests.

The 27-inch format balances usable multitasking space against a modest footprint, though native 4K text often needs scaling.

The 34-inch footprint creates an enjoyable, spacious gaming and multitasking view while requiring a sufficiently wide desk.

The dedicated sRGB mode offers an accurate starting point, but restricted adjustments in sRGB and HDR modes can frustrate users who want fine control.

An sRGB preset and adjustable color settings make it reasonably approachable to tune; software calibration can improve accuracy considerably.

The accessible USB-A connections are handy for existing peripherals, but the lack of USB-C is a disappointing obstacle for newer accessories.

HDR's eight large dimming zones create distracting halos around bright objects against dark backgrounds.

The VA LCD avoids the static-image burn-in anxiety associated with the OLED alternatives, which can matter for prolonged desktop use.

The 1500R curve wraps games around a centered player effectively, but it makes the screen less forgiving from other seats.

Desktop HDMI and DisplayPort connections are straightforward. Thin laptops and certain docks can introduce bandwidth or adapter complications.

The bundled high-speed HDMI cable and basic cables are useful; extras are limited, which reviewers generally accept for the price.

Daisy chaining is not supported, limiting setups where screens are connected in sequence.

A compact clamshell package is easy to unpack, though the slim packaging means assembling more stand pieces.

The thin, fairly light construction makes repositioning the monitor easier than expected for a desktop 4K panel.

Power use is comparatively modest for a large gaming LCD, particularly relative to OLED alternatives during gameplay.

Faint pixel inversion or scanlines may occasionally appear, though they were less noticeable than on some similar panels.

Enabling HDR restricts brightness and color controls, making SDR a more flexible choice for everyday use.

A reported sleep-and-wake problem went away after a factory reset, but the interruption is worth noting.

Sound is a point of disagreement: some hear unusually rich monitor audio, while another reviewer found it harsh, loud and short on detail.

The conventional RGB pixel layout gives clean-looking text without the colored fringes sometimes seen on alternative subpixel arrangements.

Supported 21:9 games feel more cinematic and spacious, though black bars appear in titles without ultrawide support.

Standard 100×100 mounting allows a monitor arm, which is particularly useful for portrait use or reducing desk clutter.

Equalizer and music profiles offer a bit of personalization, but one critic found these options did little to fix the speakers’ harshness.

Unexpected automatic dimming was an annoyance right after unboxing, but picture settings provided a quick remedy.

The plastic case picks up fingerprints easily and can need more frequent wiping than expected.

A built-in KVM is missing, a drawback for anyone hoping to control multiple connected computers with one set of peripherals.

The absence of PiP and PbP is a downgrade from the older model for displaying two inputs at once.

The flicker-free backlight, warm mode and ComfortView features support long sessions, with several users reporting comfortable extended viewing.

Some Nvidia setups require changing the output range manually to avoid restricted RGB over DisplayPort.
