Compare Asus ROG Swift 34 QD-OLED PG34WCDN vs Dell Alienware AW3426DW

The OSD is generally intuitive and DisplayWidget makes adjustments easier, although reaching rear ports and enabling ELMB can be cumbersome.

The central joystick and straightforward physical controls make ordinary setup and adjustment quick.

DisplayPort 2.1, dual HDMI 2.1, USB-C, several USB-A ports and a headphone output form a particularly well-rounded connection set.

Two HDMI 2.1 inputs and DisplayPort cover core video needs, while limited USB, no audio jack and no video-capable USB-C leave the hub side basic.

ELMB black-frame insertion gives lower-frame-rate games motion clarity approaching the monitor's native 360Hz mode, although it requires a more involved setup.

Unlike some higher-priced rivals, this model omits a black-frame-insertion option for further reducing perceived blur.

Gray uniformity is strong overall, but mild banding appears in some darker gradients.

Most real-world gradients look smooth with little banding, but near-black fades can reveal coarser steps in some HDR settings.

Its 90W USB-C supply comfortably exceeds basic charging-only ports and supports many laptops, even though one comparable MSI offers slightly more power.

The downstream USB-C port can top up small devices at 15W, but cannot replace a charging laptop dock.

The illuminated rear branding and desk projection add attractive flair without being overly intrusive. They favor a distinctly gaming-oriented look.

Small illuminated Alienware accents are customizable and subtle. They will disappoint anyone seeking dramatic desk-filling RGB effects.

Standard operation ranges from minimally distracting to noticeable flicker under unstable frame rates. Anti-flicker can help, but sacrifices useful VRR behavior.

Some dark scenes, menus and a video-editing app showed VRR flicker or gamma shifts, although several users did not find it distracting during games.

Instantaneous-feeling response, negligible input lag and 360Hz updates make this a standout for shooters and esports, assuming the PC can deliver high frame rates.

Fast response and a simulated smaller-screen esports option are real strengths. Players who prioritize 16:9 layouts or refresh rates above 280Hz may prefer a dedicated esports monitor.

Audio must come from external speakers or headphones. One owner does not mind the omission, but anyone wanting monitor audio will need another device.

There are no integrated speakers, so games and videos require an external audio solution. Several testers consider that an inconvenient omission.

Multiple major VRR formats are supported, but the anti-flicker setting narrows the active VRR range and can disable compensation at low frame rates.

G-SYNC, FreeSync and VESA VRR provide broad PC support and smooth frame pacing across suitable devices.

The full 360Hz advantage depends on sufficiently high game frame rates; heavy titles and weaker GPUs cannot always show the benefit.

The 3440×1440 resolution is easier to drive than 4K, though reaching 280 frames per second still calls for a capable gaming PC.

Pixel care, screen shifting, proximity-based shutoff and related settings help limit prolonged static exposure. They reduce risk rather than eliminate OLED burn-in.

Automatic pixel shifting and a stronger panel help address OLED image retention, but the menu exposes few manual care settings. The warranty provides additional reassurance.

A cluster of USB-A ports plus USB-C and KVM support adds practical peripheral flexibility, with more ports than some rivals.

The small hub is handy for peripherals and light charging, but two downstream ports and one upstream connection are basic for the class.

The 21:9 view opens up peripheral game scenery and more desktop space. Alternative aspect ratios can help focus competitive play, but consoles require manual switching.

The 21:9 canvas creates a wide, cinematic view and extra horizontal working space. Not every game or console output fills it cleanly.

ELMB offers a useful way to increase motion clarity when running below 360fps, but is incompatible with variable refresh and not available at every rate.

The extremely fast OLED pixels reduce smearing and ghosting, keeping movement crisper than typical LCD screens at comparable refresh rates.

RGB-stripe subpixels remove the characteristic fuzzy text edges of older QD-OLEDs, giving unexpectedly crisp 1440p-class results.

RGB-stripe pixels improve the clarity of text and fine UI elements, although 110 PPI remains softer than a 4K alternative and one test recommends reducing default edge enhancement.

The stand's cable cutaway and integrated switching simplify a desk with several connected devices, even if the wide monitor still needs substantial space.

A cutout in the stand keeps power and video cables tidier, though the solution is simple rather than elaborate.

VESA mounting provides a welcome route to an arm or alternative support instead of using the wide stock stand.

Standard 100×100mm VESA support makes swapping to a monitor arm simple, useful for saving space or custom setups.

Height, tilt and swivel adjustments are smooth and practical, although the stand does not pivot to portrait.

Height, tilt and swivel adjustments are smooth and flexible enough for most workstations, but portrait rotation is not a stand option.

Presence-triggered shutoff and newer panel material help offset consumption, although running at the very highest refresh rate can raise power use.

The latest OLED stack offers higher brightness without conspicuous power penalties; practical consumption is reasonable for this size and speed.

The 360Hz refresh rate is a substantial jump over older 175Hz and 240Hz ultrawides, with the biggest payoff in games that can actually reach high fps.

At 280Hz the screen feels extremely smooth and offers a useful step up from older models. It deliberately stops short of pricier 360Hz esports-focused options.

The stand is solid with little wobble, though its large pronged footprint does not always provide a clear advantage over smaller bases.

The stand supports the broad screen securely with little wobble, even during menu navigation and some vibration-heavy testing.

OLED delivers extremely deep blacks in controlled lighting, and BlackShield reduces the purple cast of older QD-OLEDs. In brighter rooms, blacks can still look gray.

Self-lit OLED pixels produce strikingly deep blacks in dark rooms, while the new coating reduces the old purple-black tint under room lighting. Strong direct light can still wash blacks somewhat.

Xbox and PlayStation signals work well, including 4K input downscaling and 120Hz play. Manual 16:9 selection and some ELMB restrictions make it less seamless than on PC.

4K 120Hz console signals, VRR and HDR can work with the right settings, but the ultrawide ratio introduces side bars and the lack of audio output complicates hookups.

A 34-inch ultrawide is less cumbersome than jumbo monitors, yet the broad, pronged stand takes room and is not everyone's preferred base.

The flat stand is generally practical for keyboards and other peripherals, although its broad base and the display's width still need desktop space.

Screen-wide consistency is generally excellent, with little dirty-screen effect, though faint banding can appear in dark material.

The panel is consistently even across the screen, without the gray banding or dirty-screen effect seen on some rivals.

The updated panel material offers added brightness without a stated increase in heat generation, an encouraging efficiency improvement.

Passive cooling avoids fan noise; one side-by-side tester measured more warmth at maximum output but found better temperature behavior at matched brightness.

The new RGB-stripe layout essentially eliminates the pink-green text fringes seen on older QD-OLED monitors, a major benefit for reading and work.

The new RGB-stripe structure largely fixes the colored outlines around fine text that bothered older QD-OLEDs, although one tester still noticed some fringing.

Exceptionally low processing delay makes even fast shooters feel immediate and reactive.

At its full refresh rate, input responsiveness is excellent and generally imperceptible in play, though one measurement set found somewhat higher low-refresh latency.

The newer coating maintains a clear, glossy-looking image while reducing reflected-light problems compared with earlier QD-OLED finishes.

The semi-gloss surface keeps images crisp and avoids a grainy matte look even as it improves glare resistance.

The moderate 1800R curve is widely appreciated as immersive without the more aggressive wrap of earlier designs.

The gently curved 34-inch screen gives games a wider, immersive feel without the distortion of more aggressive curves. A few people would prefer an even deeper wraparound.

Expansive 21:9 framing meets elite speed, striking contrast and smooth motion; the 34-inch curve feels immersive without overwhelming the desk.

A wider field of view and gentle curvature add real immersion in compatible PC games, with black bars or unsupported scenes remaining occasional frustrations.

Exceptionally broad DCI-P3 coverage and vivid QD-OLED color volume give games and HDR media rich, saturated tones.

Wide DCI-P3 coverage delivers brilliant, saturated game and film color, and well-chosen presets can keep standard content natural.

BlackShield noticeably lessens direct reflections and purple-tinted raised blacks. It cannot fully match the brighter-room black depth of some WOLED alternatives.

The revised anti-reflective coating noticeably cuts the old magenta tint and distracting glare. Direct reflections still matter more than on some WOLED alternatives.

This is widely considered an excellent high-end ultrawide, with stronger text, speed and HDR than previous generations. Pricing and some OLED compromises temper the enthusiasm.

The monitor earns enthusiastic recommendations as an approachable high-end OLED ultrawide, with connectivity and some specialist features trimmed to contain the price.

The 3440×1440 ultrawide format provides useful working space and sharp images, especially with RGB stripe. It is not as finely detailed as true 4K or higher-density rivals.

3440×1440 suits immersive gaming and side-by-side windows without 4K's graphics demands, but it cannot match the text detail of higher-density 4K screens.

Tiny bright elements can reach around 1,300 nits, making neon, explosions and reflections stand out. Larger bright scenes can lose some of that punch.

Small HDR highlights can be unusually bright and finely defined, although the most aggressive modes may sacrifice detail or overall scene brightness.

Per-pixel light control keeps bright objects from sprouting distracting halos, a significant OLED advantage over zone-dimmed LCDs.

Per-pixel illumination avoids the bright halos and blooming that can surround highlights on LCD and mini-LED displays.

Shooter, strategy and other presets, plus crosshairs and performance overlays, add flexibility. Differences between some presets are subtle.

Genre presets and Creator mode offer accessible ways to tune the picture, although the default options sometimes work better than extensive adjustments.

Near-instant OLED response avoids obvious ghost trails and inverse-overshoot artifacts, including during VRR operation.

Extremely fast OLED transitions keep motion clean, with little smearing, overshoot or visible ghosting even in fast games.

Smooth 360Hz updates and very fast OLED pixels make moving targets and camera pans extremely clean; lower frame rates show less benefit.

Fast OLED pixels and 280Hz refresh deliver exceptionally crisp movement, even if 360Hz alternatives offer a small competitive edge.

The latest QD-OLED generation combines OLED's near-instant motion and deep blacks with improved text rendering and higher brightness.

The fifth-generation Penta Tandem QD-OLED panel is central to the appeal, providing brighter HDR, deeper-looking blacks under ambient light and far more legible text than older designs.

High-bandwidth ports, VRR support and a 360Hz ceiling make it well equipped for modern PC gaming, from shooters to graphically demanding single-player titles.

Native 3440×1440 PC gaming is this display's strongest role, pairing wide-screen immersion with excellent motion and rich HDR.

Near-instant OLED transitions keep motion crisp and reduce smearing without distracting overshoot.

Near-instant OLED pixel transitions keep fast action clear and make the monitor feel exceptionally responsive.

Detailed scenes, immersive 21:9 framing and vivid HDR make cinematic single-player games look superb.

Deep blacks, striking highlights and a wraparound field of view make story-driven and atmospheric games a particular strength.

Colors and brightness stay consistent from off-center positions, a familiar advantage of OLED technology.

Color and uniformity hold up well off axis, as expected from a strong QD-OLED panel.

The integrated KVM lets one keyboard and mouse follow a change between connected computers, avoiding extra desktop switching hardware.

There is no integrated KVM switch for sharing peripherals between computers, a notable compromise compared with more fully equipped competitors.

Full-bandwidth DisplayPort 2.1 UHBR20 can run 3440×1440 at 360Hz without DSC, a standout advantage for suitably equipped PCs.

DisplayPort 1.4 with compression handles native gaming well, but enthusiasts miss the newer DisplayPort 2.1 bandwidth and uncompressed option.

Shadow Boost can make darker SDR game areas easier to inspect, but its strongest dynamic setting also alters midtones noticeably.

The Dark Stabilizer can reveal enemies and objects in shadowy games without lifting blacks completely. Higher levels sacrifice some dark-scene atmosphere.

Fingerprints and smudges wipe away more easily than on older QD-OLED coatings, a practical benefit for routine care.

The harder new surface is less susceptible to fine scratches during cleaning than earlier generations of QD-OLED coatings.

Picture-in-picture and side-by-side source modes are convenient when keeping two connected systems visible at once.

PiP/PbP options are genuinely useful for split-screen viewing and working across two inputs, with convenient positioning controls.

Dedicated sRGB and wide-gamut modes can be exceptionally accurate, and calibration results are excellent. Default oversaturation and inconsistent gamma in some modes call for attention.

Factory sRGB calibration can be exceptionally accurate, particularly in Creator mode. The default wide-gamut setting may oversaturate standard SDR material.

Higher SDR brightness can fluctuate as white areas grow, while Uniform Brightness holds a steadier but lower level. HDR peak modes can also dim substantially in brighter scenes.

Desktop brightness is fairly steady, but high-peak HDR modes can dim brighter full-screen scenes. The modes trade consistency against dramatic small highlights.

FreeSync and G-Sync compatibility help keep fast games smooth, with generally clean response even under changing frame rates. The dedicated anti-flicker mode brings its own limitations.

Adaptive Sync, G-SYNC, and FreeSync keep gameplay fluid and largely tear-free. A few accounts distinguish this smoothness from occasional OLED VRR flicker.

Clear menu organization and a responsive joystick earn praise; DisplayWidget is often quicker for complex settings.

The joystick is responsive and the menu generally easy to navigate, although its numerous layers and sometimes jagged text draw occasional complaints.

HDR is a major strength thanks to pixel-level contrast and improved peak output. No single mode combines full accuracy, peak intensity and freedom from dimming.

OLED contrast and brighter highlights produce outstanding HDR overall, with the usual tradeoff between full-scene brightness and extreme peaks.

The new panel produces brighter SDR images and impressive HDR highlights, with peaks near 1,300 nits in small areas. Large bright regions remain more restrained.

The five-layer panel is noticeably brighter in SDR and produces vivid, high-impact HDR highlights. Large bright HDR scenes remain more constrained than small specular effects.

Perfect-pixel OLED blacks alongside bright highlights create exceptional depth, especially in dark scenes.

Near-perfect OLED contrast lends depth to dark games and HDR scenes, especially compared with conventional LCD panels.

Unlike zoned LCD backlights, individual OLED pixels can turn fully off next to bright pixels, avoiding halos.

Pixel-level control makes bright and dark areas coexist cleanly without the blooming associated with zone-based backlights.

Vibrant colors, rich contrast, crisp text and clear motion produce a consistently striking image across work and games.

The newer QD-OLED panel combines vivid color, richer contrast, stronger brightness and cleaner text into an impressive all-round image.

Performance and features are compelling, but the asking price is steep compared with capable 240Hz and 280Hz alternatives. The premium is easiest to justify for speed enthusiasts.

The newest QD-OLED image quality at around the original $800 launch price impresses many testers, though some would pay more for richer connectivity.

A three-year warranty explicitly covering burn-in adds reassurance, although it cannot rule out wear after coverage ends.

The included three-year coverage for OLED burn-in is a valuable reassurance for long-term ownership.

Several measurements found gamma behavior outside the intended target, sometimes darkening or overbrightening content. Careful preset selection or calibration helps.

Well-calibrated Creator modes track their targets closely, while some default or boosted modes can appear slightly too dark or too contrasty.

Adjustable sRGB and DCI-P3 options, six-axis saturation and software tools provide strong control. An Adobe RGB preset is missed, and one sRGB mode locks certain settings.

Preset calibration is strong, but locked white-balance controls and limited per-mode adjustments frustrate some advanced tuning workflows.

DisplayWidget software makes OLED care and color adjustments easier than navigating several levels of physical menus.

Alienware Command Center provides convenient desktop control of display settings, with reported stability improvements over earlier versions.

True Black 500 tracks the target curve more accurately but limits highlights. Brighter modes can overbrighten or dim scenes and sacrifice tonal detail.

The True Black mode tends to preserve accurate scene brightness, while peak modes can dim bright scenes or overbrighten dark ones. Careful mode choice matters.

The harder coating is an improvement in principle, but scratches were seen on one tested sample, leaving real-world durability uncertain.

The stronger coating should stand up better to routine wiping and incidental contact than earlier scratch-prone QD-OLED surfaces.

Blue-light modes are available, but certain settings conflict with Uniform Brightness and the strongest filter restricts brightness.

Clearer text reduces reading fatigue for some owners, but the menu lacks a dedicated low-blue-light mode and flicker-sensitive users should take care.

At 34 inches, the display adds horizontal room for games and windows without approaching the bulk of 39- or 49-inch models.

The 34-inch width offers a sweet spot for immersion and multitasking, though its limited height may feel smaller to owners of taller 32-inch displays.

Solid construction, a refined finish and a sturdy stand help it feel premium. The angular gaming presentation may be more divisive than the physical quality.

The chassis feels solid and well assembled, with a stable stand despite a restrained plastic exterior.

Aggressive ROG styling, sharp angles and RGB flourishes look striking to some but overly gamer-focused to others.

The understated dark-indigo shell looks sleek and office-friendly, though opinions divide on its blue color and lack of the older Alienware styling.

Display Center can recognize games and automatically switch to appropriate picture presets; switching between strategy and shooter titles worked as intended.

The self-emissive OLED screen avoids the backlight bleed associated with many LCDs.

One detailed hands-on sample arrived with its protective film intact and no shipping-related micro-scratches.

PC connections are broad, and supported PlayStation and Xbox signal formats work through the available inputs. Consoles still need aspect-ratio adjustment.

Black-frame insertion markedly sharpens motion at 120Hz and 180Hz. Requiring fixed refresh, disabled VRR and multiple setting changes reduces convenience.

Automatic updates through DisplayWidget are useful, particularly for a monitor whose early firmware has drawn feature requests.

Useful game presets, dark-scene enhancements, crosshairs and an esports layout cover the essentials. Flagship extras such as strobing are absent.

True Black, Peak 1300, Peak 1300 Bright and Dolby Vision give users several looks to choose from. None perfectly balances peak punch with accuracy in every scene.

With no headphone or audio-out connection on the monitor, wired audio must run directly from a computer, console or another device.

Screen-size emulation is flexible, but a tested 27-inch mode looked softer than expected pending a proposed firmware correction.

A direct power cord avoids a bulky external brick, helping keep the desk and floor tidier.

Pixel response stays clean across refresh rates without constant overdrive adjustments, making gaming setup simpler.

Molded protection and neat internal packing keep the large display secure during delivery.

Aspect-ratio modes were not remembered independently for different inputs in early testing, forcing manual changes when swapping PC and console.

Improved text rendering and strong factory color modes help with editing, but color-critical Adobe RGB workflows may need outside calibration.

Refined surfaces, sturdy construction and a slim OLED display section help it look the part of a flagship gaming monitor.

Clean text, multitasking width, USB-C charging and KVM switching make occasional work comfortable. Continuous static desktop use is a poor match for OLED longevity.

Mode changes can require occasional manual intervention, and a few reports describe signal interruptions or mismatched color settings.

Dark-shade handling is usually good and can be improved with presets, though some HDR modes crush or coarsen the very darkest steps.

The built-in proximity sensor can black the panel when you leave and bring it back promptly when you return, supporting both convenience and care.

An integrated camera thread on the stand is genuinely useful for positioning webcam or creator accessories without another clamp.

Bottom-edge USB-A and USB-C ports are easy to reach without feeling behind the monitor, though permanently attached cables can be visible.

Common 24, 25, 50 and 60 fps video plays without obvious skips or cadence judder.

Many PC titles benefit from the wider view, but unsupported games, menus and cutscenes still introduce black bars, cropping or smaller active images.

Dolby Vision adds useful flexibility for compatible games, consoles and movies, although PC support is spotty and mode behavior sometimes needs attention.

The HDMI 2.1 connections support demanding inputs and console gaming, though 360Hz over HDMI uses DSC.

Tool-free stand assembly is quick, while the physical adjustments make positioning straightforward.

A simulated 25-inch active area makes fast competitive play easier to focus on while retaining 280Hz. A few testers saw dimmer output or questioned whether the smaller image was worth it.

Fanless ventilation avoids the whir that can accompany some actively cooled OLED competitors.

Multiple HDR modes are available, but limited brightness-curve adjustments and locked controls restrict fine tuning.

ASUS Display Center provides mouse-based access to a wider range of display settings, though its experimental voice features were unreliable in one test.

The experimental voice-controlled settings feature failed to work despite troubleshooting, making it unreliable as a real convenience.

One test found a PWM frequency that may bother especially sensitive viewers, even while typical gaming looked fine.
