Compare LG 27GX790A-B vs Dell Alienware AW2725QF

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

Most reviewers find blacks gray or washed out in darker scenes, particularly in unlit rooms. A few are satisfied with blacks when the surrounding room is illuminated.

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

Small bright objects often lack impact or detail under edge-lit local dimming, even when larger bright scenes reach respectable luminance.

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.

The conventional IPS pixel layout keeps text crisp without the colored subpixel fringes seen on some older OLED monitors.

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

The ability to switch between detailed 4K/180Hz and rapid 1080p/360Hz is the central attraction. It is most valuable to players who genuinely alternate between high-fidelity and competitive games.

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

The IPS panel delivers brightness, text clarity and immunity to OLED burn-in, while giving up OLED's deeper blacks and faster pixel transitions.

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

Sharp text, strong brightness and a burn-in-free IPS panel make this a good crossover screen for work and play.

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

The 4K panel looks razor sharp for small text and fine game detail. Lowering it to 1080p makes edges and textures noticeably rougher.

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

The pixel-doubled 1080p mode remains playable and often looks better than on 32-inch dual-mode screens. Fine foliage, text and some game details can look noticeably rough or soft.

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.

Native 4K at 27 inches delivers unusually sharp desktop and game detail; the trade is softer 1080p output when switching for maximum speed.

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

A little flicker can occur when frame rates fluctuate, particularly in the 1080p mode, but it is described as less distracting than on many VA or OLED rivals.

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

The IPS panel avoids the static-image burn-in concern that accompanies OLED alternatives, making long sessions with fixed desktop elements easier to justify.

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.

Driving 360 frames per second requires a suitably powerful PC and compatible games; the monitor's fastest mode has less benefit when hardware cannot sustain those frame rates.

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

Unlike some larger dual-mode competitors, this screen cannot shrink its 1080p image into a 24-inch competitive viewport. That limits its appeal to players who prefer a tighter tournament-style view.

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.

The compact hexagonal stand leaves room for keyboards and accessories, making it friendlier to small desks than sprawling tripod bases.

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

Typical IPS viewing angles are usable for nearby viewers and broad desktop positioning, though very wide angles and dark scenes can wash out.

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

Pixel response is fast for IPS and helps make gaming smooth, but the most rigorous measurements show blur and overshoot that hold it back from the best 360Hz screens.

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

The dense 27-inch 4K image makes small text and game details exceptionally crisp. The tradeoff is a much coarser-looking 1080p mode.

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

Motion is generally clean in the better overdrive settings, but reviewers disagree about how much trailing remains. The fastest setting can create noticeable inverse ghosting.

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

The HDMI, DisplayPort and downstream USB selection is useful, but a USB-C video input and analog audio jack are conspicuous omissions at this price.

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.

The 1080p/360Hz mode gives fast, low-lag play without buying a separate esports screen. Its pixel response and softer fine details mean dedicated high-end 360Hz displays can still be better for the most demanding competitors.

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.

On-screen timers, frame counters, aiming aids and picture controls provide a useful selection of gaming conveniences, though not every reviewer finds the extras essential.

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

Detailed 4K visuals and vivid color suit expansive single-player games, but flat blacks and modest HDR reduce their cinematic impact in dark scenes.

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

Both modes look smooth and impressively quick for IPS, with a visible benefit from higher refresh rates. Some testers say pixel response cannot fully exploit 360Hz and trails leading OLED displays.

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

The matte-to-semi-gloss coating can reduce harsh reflections, though several testers notice graininess, haze or a less satisfying compromise than a truly clear glossy panel.

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

Stand cutouts and rear routing help keep cables tidy, though a few users still find wires visible or awkward to route.

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

Some reviewers praise the matte coating for cutting mirror reflections; others see distracting glare in front of windows. Room and light placement influence the result.

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.

Several USB-A ports plus a downstream USB-C socket make accessory connections practical, but the hub is not a substitute for full USB-C display docking.

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

A broad selection of presets and creator settings is useful, with several testers finding their preferred SDR picture quickly.

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

A fast 4K gaming experience and optional 360Hz FHD mode suit varied PC games, with adaptive sync helping smooth variable frame rates.

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

Height, tilt, swivel and pivot are broadly praised for smooth, flexible positioning, although desk clearance may constrain a full turn on some setups.

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

Convenient front-bottom ports make temporary device connections easier, even though some plugs hang visibly beneath the screen.

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

The advertised 4K/180Hz and FHD/360Hz modes are the headline strengths, though the top rates require overclock settings and 360Hz cannot always be fully resolved by the IPS pixels.

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

Impressions are broadly favorable among gamers who actively want both resolutions, while others question the extra cost and reduced HDR impact.

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

There are no integrated speakers. Many gamers consider that acceptable, but buyers will need separate audio hardware.

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

The substantial base usually holds position without wobble and gives the panel a solid, secure feel.

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

Wide, vibrant color helps games and general work look appealing. Coverage is sufficient for many creators, but some competing OLEDs and professional displays reach further into demanding color spaces.

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

Low input lag is a consistent gaming advantage, especially in the higher-refresh 1080p mode. Testers report responsive aiming and little control delay.

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

The fit, finish and firm stand adjustments leave a distinctly premium impression, despite the thicker LCD enclosure compared with OLED.

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

Darkening at edges and corners is a recurring weakness, especially on bright white backgrounds. Some samples look acceptable in games, but it can distract during precise visual work.

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

Customizable rear lighting provides restrained gaming flair that can illuminate a wall without dominating the setup.

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

HDMI 2.1, 4K/120Hz and VRR make it a capable match for modern consoles. Its missing onboard audio options are less convenient for certain console setups.

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

One owner voices frustration that OLED models were receiving updates while this IPS variant appeared overlooked; ongoing firmware support is a concern rather than an established failure.

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

High resolution and natural color help photo editing and everyday visual work, though specialist proofing still calls for closer attention to gamut and uniformity.

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

Limited USB-C charging wattage is useful for small peripherals but not convincing for powering a gaming laptop or serving as a docking connection.

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

Standard 100×100 mm VESA mounting makes it easy to replace the included stand with a compatible arm or wall mount.

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

Variable-refresh support works across PC gaming modes and modern consoles, helping keep play smooth without tearing.

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

Contrast remains a prominent weakness of the conventional IPS panel, particularly next to OLED or strong mini-LED alternatives. Some brighter-room use is less affected.

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.

Reviews are split: some find satisfying brightness and color, while others call HDR flat and unconvincing. Weak dark-scene contrast and crude edge dimming are the recurring caveats.

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.

Mode switching is normally quick with the joystick and can be configured reliably. Some testers encounter application mismatches, brief freezes or a stuck on-screen overlay when changing modes.

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

High SDR brightness is a consistent strength, frequently measured near or above 450 nits. HDR brightness results vary by mode and test, and small highlights are not always punchy.

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

Accurate, pleasing SDR colors are a major selling point, especially in sRGB or after calibration. Some testers still flag factory settings or slight deviations that matter for color-critical use.

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.

DisplayPort 1.4 is regarded as adequate for this monitor's advertised resolution and refresh-rate combinations; a newer connector is not essential here.

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

Sharp, bright, colorful 4K output wins praise, especially for SDR and daytime use. Evaluation turns more negative when comparing HDR contrast and dark scenes with OLED competitors.

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

The dark stabilizer can brighten shadowed areas for play, offering a useful visibility adjustment.

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

G-SYNC and variable refresh operation are generally praised for smooth, tear-free play across the monitor's resolution modes.

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

Most find the centered joystick and logical menus fast to navigate. Dark menu text, tiny labels and a too-easy mode shortcut bother a few users.

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

Gamma tracking and the sRGB calibration earn praise for keeping tonal output predictable, with only minor corrections needed in some tests.

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

Creator, Custom Color and HDR tuning offer meaningful adjustment; some controls are restricted to particular modes. Calibration can improve already good color reproduction.

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

Custom HDR color controls allow unusual freedom to adjust hue, saturation and contrast, although Smart HDR can lock standard brightness sliders.

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

Dell Display Manager offered useful controls and window layouts after Alienware Command Center failed to detect the monitor for one user.

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

Dolby Vision's dynamic mapping and HDR tracking impress some testers, but results can still vary unexpectedly with picture modes and content.

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

One owner's experience suggests early panel revisions could have defects while a later replacement improved things; long-term reliability is not established across the broader sample.

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

Value depends heavily on using both modes: fans of the flexibility see a fair bargain, while several reviewers prefer cheaper 4K IPS or similarly priced OLED alternatives.

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

Dual HDMI 2.1 inputs are praised for carrying high refresh rates and modern-console 4K/120Hz signals without sacrificing the monitor's gaming flexibility.

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

Tool-free or near-tool-free stand attachment is quick and straightforward, with the included cables helping users start gaming sooner.

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

The 27-inch size strikes a sensible balance for 4K sharpness and 1080p esports play, even though some users would prefer 32 inches for cinematic games or a single large workspace.

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

The clean black enclosure, slim bezels and understated RGB earn frequent praise. Some note it is bulkier than thin OLED designs, but it suits both gaming and workspaces.

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

The chassis, stand and assembly generally feel sturdy and well finished, with little flex and a reassuringly solid base.

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

Slim borders make the monitor a neat fit for paired-screen arrangements and keep the gaming styling visually restrained.

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

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

Light bleed and IPS glow weaken dark scenes, although one owner reports little visible bleed in a normally lit room. This is not an OLED-like black presentation.

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

The coarse edge-lit dimming sometimes casts obvious halos around bright objects and subtitles, although one test found small highlights less prone to obvious blooming.

Recyclable molded-cardboard packaging replaces the usual crumbly foam, a practical improvement in material choice.

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.

Several HDR10 and Dolby Vision presets let users tailor the look, with Custom Color HDR singled out for its stronger image.

The lack of a 3.5mm audio output is a recurring complaint, particularly for headsets, wired speakers and users swapping between sources.

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

The pop-out hook is a clever convenience for keeping a headset off the desk, although its usefulness varies and one reviewer found a heavy headset could tilt the monitor arm.

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

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

A built-in supply avoids an external power brick and keeps the desk and cable arrangement simpler.

The middle settings usually balance speed and overshoot; aggressive modes can produce inverse ghosting and often require retuning across refresh rates.

The option to synchronize settings between resolution modes or maintain separate profiles makes switching more manageable.

An owner reports severe stuck-pixel issues with early revisions and fewer defects after replacement, making panel inspection and revision checking worthwhile.

The 27-inch chassis was easy for one tester to handle during setup and felt lighter than several comparable displays.

Power draw is reasonably restrained for a bright 4K IPS screen, sitting between more and less efficient competing displays.

Switching between separate SDR and HDR presets can be inconvenient because SDR color looks wrong in some HDR settings.

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

Night vision, aiming points and sniper-focused overlays add useful targeting aids for players who want on-screen assistance.

HDMI audio return and passthrough add a useful way to connect compatible soundbars and external audio gear, partly offsetting the missing analog headphone output.

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

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.

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.

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

The edge-lit zones offer little useful control over dark and bright elements. Several tests describe haloing, raised blacks or muted highlights, with limited ability to disable dimming in HDR.

Sniper and aiming overlays can help spot or target distant threats, although their value depends on whether the player uses visual assists.

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

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

The center-mounted joystick is quick to reach and responsive, though its shortcut behavior can make accidental resolution changes frustrating.

One tester could not get Alienware Command Center to recognize the screen despite installed drivers, turning instead to Dell Display Manager.

Dolby Vision and its picture-mode options are welcome, but reviewers disagree about the practical improvement because the IPS backlight cannot deliver truly deep blacks.

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

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