Compare Dell Alienware AW2725DF vs LG 27GX790A-B

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.

Updates can improve some display behavior, but reported screen-splitting and connection glitches were not fully resolved for every user.

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 coating diffuses glare effectively under many lights, although direct windows and edge-spread reflections remain distracting for some.

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

Noticeable gray streaks, dirty-screen effects and dark-scene banding appear on some units, even after cleaning cycles.

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

The package includes useful HDMI, DisplayPort, and USB cables, reducing the need for extra setup purchases.

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

The matte finish controls mirror-like reflections with little obvious grain for some, but others prefer a glossy surface for maximum crispness.

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

PS5 and Xbox work with modern HDMI signals and enjoy OLED contrast, but they cannot exploit 480Hz and a few lower-refresh quirks remain.

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

The 24-inch emulation mode can look blurry or incorrectly mapped, making native full-screen 1440p the more reliable choice.

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.

The screen handles basic work, but small-font clarity and gray-uniformity drawbacks make it less versatile than sharper office-oriented alternatives.

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

Game visuals look clean at QHD, but some desktop fonts and interface elements appear softer or more pixelated than on a 4K screen.

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

Small fonts can have colored edges or a hazy outline because of the WOLED subpixel pattern and matte coating, reducing its appeal for heavy reading.

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.

Two USB-A ports are handy for a mouse and keyboard, but the limited hub and missing USB-C do not replace a fuller workstation dock.

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.

Pixel movement, a screen saver, cleaning functions and standby behavior help manage OLED wear, but prolonged static interfaces still require care.

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 broad metal base stays low and leaves usable space above it for desk accessories, though its footprint and bulk will not suit every layout.

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

Reaching the full 480Hz benefit calls for unusually high, steady frame rates and a powerful PC. Lesser rigs still run smoothly but leave much of the panel untapped.

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 2.1 sockets, DisplayPort 2.1 and a modest USB hub cover gaming essentials, but the lack of USB-C is conspicuous.

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 panel displays richly saturated colors and substantial DCI-P3 coverage, even if QD-OLED alternatives reach a little farther into wide-gamut spaces.

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

The fast OLED panel leaves little visible trailing or smearing, with minor overshoot seen in tests but generally hard to spot in play.

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

Constant-brightness operation and adjustable color controls help with Photoshop-style work, though high-resolution alternatives remain appealing for detail work.

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

There is no USB-C charging output, so handhelds and laptops need their own power connection.

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

The standard 100×100mm mount supports alternate stands or arms if the included base is not a good fit.

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

Official FreeSync and G-SYNC support gives AMD and Nvidia owners flexible, tear-reducing operation; the separate flicker issue remains a caveat.

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

Controls feel exceptionally immediate at high refresh rates, though older firmware and some 60Hz situations have drawn complaints.

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

Pinpoint highlights are vivid, and bright objects generally retain convincing texture; the panel cannot sustain the same punch across large bright areas.

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

Deep OLED blacks, rich colors and vivid effects make immersive games a pleasure, though full-screen brightness trails newer panels.

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

There are no integrated speakers, leaving users to rely on a headset, desktop speakers or the headphone output.

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.

The stand includes a useful pass-through and accessible connections, though one low-positioned route can leave visible cables.

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.

Individually controlled OLED pixels deliver convincing, nearly ink-black shadows and an immersive dark-scene image.

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 strikes a useful balance for extremely high frame rates and looks pleasing in games. It lacks the extra sharpness of competing 27-inch 4K OLEDs.

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

Crosshairs, a frame-rate counter, and shadow-enhancing controls are useful, but specialty tools such as timers are missing and the 24-inch emulation disappoints.

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.

With suitable hardware, the monitor combines native 1440p with extraordinary speed and broad sync support. Its biggest advantages live in fast PC titles.

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

Metal stand components, a slim frame and neat styling give the display an expensive, carefully built feel.

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 pivot are handled smoothly and precisely, making it easy to tailor the panel position.

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.

There is a generous selection of picture modes and game-oriented overlays; some HDR simulation and gamma choices need tuning.

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

Frame-rate swings can produce pronounced brightness flicker, most conspicuously in dark scenes, so stable frame caps or fixed refresh may be preferable.

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.

The hexagonal rear lighting adds restrained gaming flair, though its brightness and customization may feel limited next to showier setups.

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

A native 480Hz refresh makes motion dramatically smooth and is its clearest reason to buy, provided the PC can render enough frames.

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

The solid, low-profile metal base keeps the panel steady while allowing repositioning, with only minor complaints about size or shape.

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.

This is a standout fit for serious esports players who can drive 1440p at very high frame rates: targets stay crisp and controls feel immediate.

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

The fast, colorful OLED gaming experience wins strong praise, but this specialized screen leaves value-focused and productivity-first buyers with better options.

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

Extremely rapid pixel transitions keep edges crisp even through frantic camera movement, supporting the monitor’s esports strengths.

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.

Almost blur-free 480Hz motion is the defining attraction, keeping fast-moving targets and small details clear in competitive games.

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

WOLED provides near-instant pixel response and perfect blacks, while its subpixel arrangement and older-generation brightness impose tradeoffs.

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

Colors and contrast remain strong from off-axis seating, especially when compared with some newer WOLED alternatives.

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.

Two HDMI 2.1 inputs are a good match for game consoles and additional devices, adding welcome flexibility to a PC-focused display.

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.

Warranty duration and burn-in terms are a recurring source of caution, particularly alongside longer rival guarantees and third-party sellers.

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.

The monitor looks strongest on sale: its unique 480Hz speed can justify the premium for enthusiasts, but regular prices invite faster or sharper rivals.

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

OLED wear and sporadic display glitches make long-term care and firmware stability more consequential than on a typical LCD.

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

Basic assembly and connections are straightforward, with the panel clipping onto a stable stand and useful cables included.

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 27-inch footprint suits many competitive setups, but some prefer a smaller tournament-style screen or a larger cinematic display.

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 panel and metal stand feel sturdy, with precise moving parts and a solid construction that matches its premium positioning.

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

Low-blue-light treatment and adjustable brightness help some users, but others report tired eyes or discomfort during extended use.

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

A thin panel, narrow bezels and restrained dark styling look polished, with minor complaints about reflective trim and the stand.

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 welcome gaming connection, but UHBR13.5 bandwidth still requires compression for 1440p at 480Hz, and occasional handshake problems have been reported.

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.

Constant-brightness modes keep desktop luminance steady, while variable modes add extra pop for games and video. A higher peak setting can make brightness changes more obvious.

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.

Color can look excellent once calibrated, but out-of-box white balance and gamma results vary sharply between tests and modes.

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

There is no built-in KVM, limiting convenience for people who want a single keyboard and mouse to follow multiple computers.

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.

Vivid colors, exceptional contrast and striking HDR detail make games look fantastic; uneven dark grays and modest resolution temper the result.

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

The joystick menu is generally quick and easy to navigate, although a remote or more direct controls would suit some people better.

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.

HDR is especially captivating when bright effects appear against deep black surroundings. Some comparisons favor newer OLEDs for sustained brightness, but the older panel can track intended HDR tones more faithfully.

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

Shadow-lifting adjustments can uncover hidden details in darker games and partly offset occasional near-black crushing.

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.

Brightness is generally adequate for a gaming room and HDR highlights stand out, but sunny offices and the newest OLED rivals reveal its limitations.

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

Per-pixel OLED lighting gives almost bottomless contrast, especially effective when small bright objects appear in dark scenes.

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

The internal cooling arrangement is described as very quiet, with no distracting fan noise in normal use.

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

The older panel is praised for preserving intended HDR brightness more faithfully than some newer modes, though peak settings can still compress highlights.

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

Adjustable white balance, gamma, gamut, and even hardware calibration offer unusually flexible fine-tuning. A colorimeter is useful if color precision is a priority.

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

LG’s Windows utility is usable rather than elegant, and firmware changes have delivered both picture improvements and unresolved glitches.

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

Some measurements are very accurate while others find bright midtones, crushed shadows or awkward preset behavior. Calibration and firmware can make a substantial difference.

The menu and day-to-day controls are approachable, although extracting peak performance and handling OLED care may be demanding.

The smaller simulated play area is a poor substitute for a native 24-inch screen: it looks blurry and its pixel mapping is unconvincing.

The familiar 16:9 proportions work naturally with the 27-inch QHD size and fit the preferred desktop layout.

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

LG omits black-frame insertion, leaving more persistence blur at lower refresh rates than rivals with dedicated motion-blur reduction.

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

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

There is no 4K/1080p dual-resolution switch; the panel stays focused on native 1440p esports gaming rather than covering two distinct gaming modes.

Crosshairs and frame-rate overlays are present, but the omission of timers disappoints users expecting a fuller set of esports aids.

Dark gradient steps and gray banding can be visible, especially near black; refresh routines or firmware adjustments may reduce the problem without guaranteeing its removal.

The four-pole headset output is convenient, and DTS processing can add impressive depth and bass without external speakers.

OLED retention and burn-in remain considerations for long sessions with static heads-up displays, despite onboard protection tools.

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

QHD at 27 inches is sharp enough for many games, but 4K displays deliver visibly finer details, particularly with tiny interface text.

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.

Deep black is a strength, but some dark-gray detail can disappear or look too elevated depending on the selected mode and firmware.

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

Rear-facing connections are relatively easy to reach, while the nearby headphone jack and straightforward layout simplify peripheral changes.

Broad FreeSync and G-SYNC support is a plus for fluid gaming, although VRR flicker and occasional mode instability complicate the experience.

Three DTS headphone modes provide distinct sound presentations, adding welcome flexibility for gaming and entertainment.

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

Rich hues stand out beautifully against OLED blacks, although bright saturated colors are not as intense as on some QD-OLED or newer tandem-OLED panels.

Some accounts describe a two-tone split image after waking or applying calibration, along with occasional connection handshakes. Changing modes may temporarily restore the image.

DTS Headphone:X adds useful directional cues and fuller sound through headphones, making it a worthwhile extra for headset users.

HDR picture modes retain useful brightness and color-temperature settings, allowing substantial adjustment rather than locking the entire image.

Very slim borders give the panel a clean, nearly floating appearance, even though a reflective strip below the screen may catch light.

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