Compare Dell Alienware AW2725DF vs LG 27GX790B-B

The HDMI connection is the standout connectivity compromise: despite HDMI 2.1 labeling, its bandwidth is restricted and it cannot carry native 1440p at 360Hz.

High-bandwidth HDMI ports support current gaming devices and offer flexibility alongside DisplayPort.

Dell's three-year support and explicit burn-in coverage are major reassurances for an OLED purchase, though coverage cannot eliminate the underlying wear risk.

A two-year OLED warranty looks weak beside some competitors offering three years or more.

The combined speed and OLED image can justify a premium for dedicated gamers, especially when discounted. Buyers who value size, resolution or connectivity more may see poor value.

At a steep discount, its 540Hz OLED performance compares favorably with pricier rivals; at full price, many gamers can spend far less without giving up much.

Tool-free stand assembly and straightforward installation make getting started quick, even though rear cable covers can require a little care.

Tool-light assembly and straightforward stand attachment make initial setup simple.

The semi-glossy QD-OLED finish looks clearer and less grainy than many matte OLED coatings, with extra reflections as the tradeoff.

The matte coating cuts reflections but looks less crisp and punchy than glossy rivals to some viewers; preferences are sharply divided.

Consoles can use 1440p at 120Hz, but limited HDMI bandwidth restricts higher-bandwidth modes and complicates the ideal 4K HDR/120Hz combination.

A PS5 Pro worked well in hands-on play, with smooth motion and appealing OLED visuals.

The glossy coating creates a clean, vivid image but reflects windows and lamps; raised purple blacks are particularly noticeable under direct ambient light.

The matte surface is effective against ordinary reflections, although direct window glare can still overpower it.

The display can handle occasional desktop tasks, but OLED wear concerns and text rendering prevent it from being the most comfortable all-day work monitor.

Good QHD clarity and easy setup suit general work for some users, but OLED text artifacts are noticeable for others.

The default sharpening can exaggerate edges or make tiny details look spotty; lowering it produces a more natural picture for some users.

Native 1440p delivers crisp graphics, but the optional 720p mode produces conspicuous softness.

The USB-C accessory port can charge small devices at limited wattage, but it does not offer meaningful laptop power delivery or carry video.

The USB-C port supplies only 5W, far too little to charge most laptops adequately.

The stand's routing channel and rear cover are useful for hiding wires, although recessed video ports can be awkward to reach when swapping devices.

Some testers miss an opening through the stand, although one found the included rear clip effective for bundling cables.

1440p is a useful sweet spot for detailed gaming at very high frame rates, but fine desktop text and modern 4K content cannot match the crispness of true 4K screens.

Native 1440p looks good at 27 inches, but enabling 720Hz reduces the image to a very soft 720p; detail-focused buyers may want 4K.

Colorful, accurate Creator presets make the panel enjoyable for photo edits, with attention needed to SDR calibration and prolonged static screens.

The colorful QHD panel can handle everyday photo edits, though color-critical work calls for carefully chosen presets.

Brightness uniformity is strong in one measurement but another test found visible corner darkening, making this a modest point of disagreement.

Findings differ: one tester saw mostly even color and brightness, while another sample had conspicuous gray-screen texture.

Variable-frame-rate gaming can produce visible flicker, most noticeable during darker scenes or erratic performance; a stable frame rate helps.

Flicker is a concern in variable-refresh use, though an OLED flicker mitigation control can help in some scenarios.

Atmospheric, narrative-driven games benefit enormously from saturated color, precise highlights and black scenes, even when they do not approach 360fps.

Deep blacks, vivid colors, and bright HDR make cinematic games attractive, though glossy or higher-resolution alternatives may be more immersive for solo play.

Pixel and panel refresh routines help manage OLED wear, backed by a three-year burn-in warranty. The relatively limited user-adjustable safeguards and persistent static-content risk remain drawbacks.

Screen savers and OLED cleaning features offer useful precautions, but short tests cannot guarantee long-term protection from static-image wear.

The compact hexagonal foot usually leaves extra desk space for a keyboard and surrounding equipment. Its shape can suit multi-monitor arrangements as well.

The base occupies a moderate amount of desk space, and its screen can sit farther forward than expected.

Two DisplayPorts and convenient USB accessory ports are useful, but limited HDMI bandwidth, no USB-C video input and the lack of audio output make connectivity feel incomplete.

Two HDMI inputs, DisplayPort, USB-C, and USB-A provide welcome flexibility, although some would like another HDMI or easier physical access.

The compact stand is usually firm, but wobble during repositioning and individual ergonomics complaints keep experiences from being unanimous.

The weighted, flat metal base remains stable while the screen moves and can hold small desk items.

Reaching the 360Hz ceiling at 1440p demands a powerful computer or less demanding game settings, so the speed advantage is conditional.

Even expensive gaming systems often fall well short of 540–720 fps in modern games, restricting the benefit of the highest modes.

Height, tilt, swivel and pivot adjustments help fit the display to varied positions, and the mounting and movement generally feel straightforward.

Height, tilt, swivel, and portrait rotation make it easy to set a comfortable position.

A useful downstream USB-A and USB-C arrangement keeps mouse and keyboard peripherals handy, though it does not turn the monitor into a USB-C laptop dock.

The built-in USB ports add convenience for peripherals alongside the display inputs.

A very wide gamut produces rich, saturated colors and notably strong HDR color volume. This is consistently one of the monitor's most admired visual qualities.

The wide color gamut gives games vivid, rich color; color purity is a frequent highlight of the newer Tandem OLED panel.

Inky, individually controlled blacks are a defining strength for games and movies in controlled lighting. Direct room light can lift the panel to a grayish or purple appearance.

OLED produces exceptionally deep blacks, making night scenes and highlights more convincing.

Subtle AlienFX lighting gives the back of the monitor some character, and the colors can be adjusted or disabled. The uneven rear glow does not appeal to everyone.

Rear RGB is customizable and subdued enough not to dominate the desk.

Native 360Hz refresh is the headline advantage, bringing exceptional speed and refined motion for esports without requiring lower resolution on the panel itself.

Native 540Hz QHD feels extraordinarily fluid and crisp. The 720Hz option is less universally useful because it drops to 720p and demands extremely high frame rates.

Very low display lag delivers quick-feeling mouse and controller responses, an advantage in fast competitive titles.

Fast responses and negligible perceived delay help games feel connected and snappy, including when frame rates are below the monitor’s peak.

Exceptional clarity, low lag and up to 360Hz make this a particularly strong competitive PC gaming screen when the system can deliver high frame rates.

Serious esports players get exceptionally clear motion and responsive control, especially in lightweight shooters that can run at hundreds of frames per second.

Overall satisfaction is very high among gamers enjoying the OLED upgrade, with some caveats around cost, reliability and panel upkeep.

A standout specialist for high-frame-rate PC gaming rather than a universally ideal monitor; image compromises and value depend heavily on how you play.

Near-instant OLED pixel transitions keep fast objects clean and responsive without the usual LCD overshoot or trailing.

Near-instant OLED pixel transitions keep fast motion clear and avoid the smearing associated with slower panels.

Creator and Smart HDR modes offer useful options, but default desktop, movie and game presets can produce blur, excess saturation or uneven brightness depending on content.

Genre presets and personalized adjustments make tuning easy; several modes look similar, and color fidelity varies between them.

Fast-moving objects show very little ghosting or overshoot, keeping rapid camera pans unusually clean at high refresh rates.

Very fast OLED response keeps trailing and smearing minimal in rapid action.

The 360Hz QD-OLED panel keeps fine moving details visible and cuts blur noticeably compared with lower-refresh displays. The gain over 240Hz is real but subtler than larger refresh-rate jumps.

Fast-moving objects show remarkably little blur or trailing, helping target visibility and making rapid camera movement feel precise.

This third-generation QD-OLED implementation wins praise for its combination of color volume, contrast and rapid response.

The newer Tandem OLED architecture delivers unusually bright, vibrant imagery while retaining fast OLED response.

Connected over DisplayPort, this is an outstanding PC gaming display with remarkably clean motion and low lag. Gamers need a capable PC and the right connection to make the most of 360Hz.

High-bandwidth ports, variable refresh, and spectacular motion make it well suited to fast gaming PCs that can push high frame rates.

The clean styling and polished thin panel give a premium first impression, though plastic construction tempers the luxury feel.

Slim bezels and restrained styling give the display an upscale front appearance, even though much of its housing is plastic.

Third-generation QD-OLED reduces the colored edges seen around small text, but fringing and lower text crispness remain noticeable to sensitive users.

Experiences vary from crisp, perfectly usable fonts to visible fringing on dark text over light backgrounds, especially during prolonged office work.

The jump from a smaller esports display to 27 inches offers more room for work, but can initially feel unfamiliar for highly practiced players.

The compact, thin-bezel 27-inch form fits common desktop setups without demanding an oversized desk.

The plastic housing is usually regarded as solid and attractive, although a few accounts describe hollow sections, flex or creaking rather than a luxury construction.

The flat metal stand adds substance, but the main chassis is ordinary plastic and not especially premium for the price.

The restrained black-and-gray Alienware styling attracts praise for looking futuristic without becoming gaudy, although some find the housing or bezels overly bulky.

The minimalist silver-and-black design fits both gaming rooms and workspaces, with subdued rear lighting rather than excessive decoration.

Small bright details can look dazzling, but full-screen SDR brightness is modest and heavily lit rooms expose its limits. Experiences with actual brightness vary across modes and tests.

The Tandem OLED reaches impressive HDR brightness for its class, although sustained brightness can fall and direct sunlight remains demanding.

SDR brightness generally stays steady without obvious automatic dimming, while brighter HDR scenes can trigger a noticeable drop in overall luminance. Some testing also raises questions about brightness behavior with particular backgrounds.

Peak luminance can reduce after sustained output, making short highlights more impressive than prolonged bright scenes.

Colors can be remarkably accurate, particularly in Creator sRGB mode, but the default wide-gamut presentation can oversaturate SDR content and the DCI-P3 preset draws mixed assessments.

The sRGB mode improves on older LG models, but standard gaming modes can appear oversaturated; calibration may be worthwhile.

OLED contrast, color and concentrated highlights make HDR games and films appealing, but sustained bright scenes are less impactful than on strong Mini-LED displays.

Bright highlights and perfect blacks create striking HDR games; some evaluations note inaccurate overbrightening and the matte finish softening the visual pop.

The joystick-driven OSD is usually intuitive, responsive and easy to navigate, although a few software quirks and limited controls attract criticism.

A compact joystick and straightforward menus make settings easy to find and change.

Vivid colors, deep blacks and highly fluid motion combine into a striking gaming image; modest room-light performance and some mode-specific tuning keep it from being universally ideal.

Rich OLED colors, superb contrast, and sharp native QHD images make games look excellent. Some testers dislike the matte finish and uneven gray-screen texture.

DisplayPort is the reliable path to native 1440p at 360Hz, making it the preferred connection for high-frame-rate PC gaming.

DisplayPort 2.1 is a useful match for powerful PCs trying to get the most from the panel’s demanding refresh rates.

Pixel-level OLED control creates striking contrast and clean bright-on-black detail in dark environments, although direct light lessens the perceived advantage.

Excellent OLED contrast keeps dark areas black while bright highlights pop, especially in atmospheric games.

Creator presets and custom color adjustments offer useful calibration choices, though there is no hardware calibration and some control options are limited.

The extensive color menus and personalized picture mode allow meaningful adjustment when stock presets look too saturated.

HDR mode and preset accuracy are uneven: some preserve highlight detail well, while others darken scenes, crush detail or create excessive saturation.

HDR can render scenes brighter than intended, so the panel’s luminous highlights do not always translate into the most accurate presentation.

Controls and setup are broadly intuitive, with convenient adjustment once the menu layout is familiar.

OLED pixels eliminate the conventional LCD backlight bleed that can wash out dark corners, keeping black areas clean.

Bright objects sit against black without the blooming or halos of zone-lit LCDs, making night scenes especially striking.

The lack of speakers leaves console and streaming-device users arranging external audio, which can make otherwise straightforward hookups less convenient.

One arrival had a battered shipping carton but the monitor itself was undamaged, so the reported delivery result was ultimately reassuring.

Switching between 540Hz QHD and 720Hz HD creates choice, but several testers found the softer 720p image too costly for the modest speed benefit.

Firmware can be updated through Dell's tools, and an update apparently resolved one instance of intermittent gray-screen failures. The update process adds another setup step.

Crosshairs, frame-rate indicators, AlienVision and shadow tools cover useful gaming extras, though the broader feature set feels lean relative to some premium rivals.

Specular HDR details look vivid and sharply separated from black backgrounds, though the high peak is restricted to very small bright areas.

Audio presets through the headset jack sound pleasing, with choices for different listening needs.

Downscaled virtual-4K modes can help some HDMI devices, but the resulting 1440p image and restricted output modes limit their usefulness.

The supplied stand, signal cables and accessories make setup convenient, although the missing HDMI cable in some kits is criticized.

An external adapter adds another object to manage on or beneath the desk.

The packaging usually protects the panel well, although at least one unboxing showed conspicuous box damage.

The lighter plastic chassis makes moving or mounting the monitor easier.

It wakes or powers on promptly in hands-on use.

Higher power draw than expected, including unusual standby use in one test, weakens the efficiency case compared with some conventional screens.

Well-managed SDR content in HDR mode can reduce the need for constant switching between display modes, provided its brightness tradeoffs are acceptable.

A small number of experiences describe serious picture-loss or maintenance-cycle problems that interrupt use, despite otherwise positive day-to-day operation.

The rear-facing connectors are handy for some setups but require turning the display around in others.

Standard 100×100mm VESA support makes it straightforward to swap the supplied stand for a wall mount or monitor arm.

Wide OLED viewing angles maintain color and contrast well when the screen is viewed away from center.

Variable refresh rate works smoothly across supported modes in many setups, although its benefits diminish when frame rates fluctuate enough to cause flicker.

Smooth, tear-free play is reported in real-world testing, though there are some cautions about flicker with variable refresh.

Dark Stabilizer and the shadow-enhancement options can expose opponents or details in dim game areas without dramatically lifting all the blacks.

The glossy glass can show smears and small spots easily, so regular cleaning may take more effort than on a typical matte LCD.

Switching between refresh profiles worked smoothly in one test, but automatic switching between devices was less dependable.

An optional smaller-screen competitive view is available, but its practical value is limited for players who prefer the full QHD image.

There is no KVM to share a keyboard and mouse conveniently across computers, despite a useful USB hub and multiple video inputs.

Cooling-fan noise is generally unobtrusive, but a very quiet environment may make the internal fan faintly audible.

Headphone processing and sound presets are well liked in one hands-on assessment.

Some find the screen comfortable in dim conditions, but flicker sensitivity and one account of pronounced eye strain make comfort highly individual.

The glass finish is surprisingly easy to mark or smear and needs careful handling to maintain its clean appearance.

Gamma looks reasonably close to target in several modes, but some preset tracking and fine-adjustment limits prevent consistent precision.

Long-term confidence is mixed: isolated reports describe freezes, lost pictures and exchanges, while a firmware update resolved one reported gray-screen issue.

Dell Display Manager and Alienware software offer convenient access to image presets and updates, but occasional control quirks remain.
