Compare LG 27GX790A-B vs Dell Alienware AW3225QF

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

The joystick and daily operation are straightforward, while HDR preset choices, care routines and device handshakes can require extra tinkering.

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

The standard 16:9 shape works naturally with consoles and most games. Ultrawide fans may miss the extra horizontal field of view.

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.

Gradients and near-black transitions can be very smooth, with little visible banding in well-tuned modes. Some HDR settings and firmware combinations have drawn complaints.

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

Sharp rendering, broad gamut and a competent sRGB profile can make photo work appealing. Full-time static editing is more conditional than gaming because of OLED burn-in considerations.

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 broad, deep stand is stable but can crowd narrow desks and leave the panel uncomfortably close. A VESA arm is an attractive alternative.

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

Operating-system scaling can make 4K text comfortable at 125%, but some apps show inconsistent sizing and require adjustment.

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

Useful video, USB and power cables come in the box, making a standard desktop setup straightforward without extra accessory hunting.

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

The glossy coating looks clear but shows specular reflections, and ambient light raises blacks. It is best positioned away from direct light sources.

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

White and dark-grey screens look even on well-performing units, without obvious dirty-screen patterns.

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

G-SYNC, FreeSync and variable refresh support help keep frame delivery smooth across PCs and consoles, with occasional flicker in challenging scenes.

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.

Reaching 240 frames per second at native 4K is demanding even with powerful graphics cards. Upscaling or lower frame rates remain practical ways to enjoy the panel.

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

Two strong HDMI connections and a useful USB hub serve gamers well. Limited USB-C functionality, missing KVM and no ordinary audio jack are recurring omissions.

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.

Fine text is much cleaner than on previous QD-OLED models; fringe colors are very hard to notice at normal viewing distances.

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

Third-generation QD-OLED provides a major jump in perceived contrast, color richness and speed, while retaining the usual OLED brightness and static-image caveats.

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

Standard VESA mounting lets users replace the large stock stand with a monitor arm, improving desk placement flexibility.

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

Near-instant pixel transitions leave virtually no smearing, overshoot or inverse ghosting, keeping fast moving scenes clean.

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

In controlled light, pixels switch fully off for exceptionally deep blacks. Daylight can give the QD-OLED surface a noticeable purple or grey cast.

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

The monitor excels with well-equipped gaming PCs, combining 4K, 240Hz, VRR and exceptionally fast pixels. Achieving the maximum frame rate can take substantial GPU power.

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.

Very low lag, fast pixels and 240Hz make competitive play responsive; extreme esports players may prefer 360Hz or 480Hz alternatives and smaller screens.

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

4K density and improved text quality make everyday work far more realistic than with earlier OLEDs. A curved panel, static-content risk and limited docking still restrict all-day office appeal.

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

A handsome design and sturdy assembly usually match the high-end positioning, although some would prefer a thinner, more metal-rich body.

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

Small HDR highlights can be brilliantly bright and sharply isolated, though some modes crush or flatten details and brighter full-screen scenes limit peak output.

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

The jump to 240Hz offers obvious smoothness and clarity when supported by high frame rates. Even below its ceiling, the fast OLED panel stays responsive.

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

Fine textures and lettering look crisp thanks to 4K resolution, including the unexpectedly clean text for an OLED screen.

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

Colors and contrast remain impressively consistent off-axis, preserving the image quality when seated away from center.

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

Variable-refresh flicker can appear in dark or rapidly changing frame-rate conditions. Some users barely notice it, while more sensitive observers report distractions.

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 brings clearly sharper textures, detailed game environments and improved everyday text rendering. Some users need interface scaling, and high frame rates require serious hardware.

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

Rich HDR scenes, deep blacks, sharp 4K assets and the gently curved 32-inch screen make story-driven games particularly immersive.

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

A three-year burn-in warranty and automatic care routines offer reassurance. The limited number of adjustable OLED protections draws criticism.

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

Height, tilt and swivel cover most everyday positioning needs. Lack of pivot and the broad stand shape may limit certain layouts.

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

Movement is unusually sharp at 240Hz, rivaling some faster LCD monitors and making rapidly moving targets easier to follow.

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

Owners and testers acknowledge the usual static-image burn-in risk of OLED. Encouraging long-term reports include panels with no visible permanent retention after substantial use.

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

The rear AlienFX accents are subtle and customizable, adding personality without being central to the picture. Anyone wanting a restrained look can disable them.

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

The stand cutout and rear connection cover help keep cables out of sight, complementing the tidy black-and-white design.

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

Full-bandwidth HDMI 2.1, VRR, HDR and Dolby Vision offer excellent modern console compatibility. The 16:9 panel avoids ultrawide game-format issues.

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

Instant-feeling OLED pixel response keeps both high- and lower-refresh motion very clean, with no need for typical LCD overdrive adjustment.

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

The substantial base generally holds the large panel firmly, although some testers noticed a little wobble when adjusting the display.

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.

Crosshairs, frame-rate tools, presets and AlienVision overlays supply useful gaming extras. Some are more gimmicky than essential, but the controls are fairly convenient.

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

Low USB-C charging power and no video input are repeatedly singled out as missed premium conveniences, especially compared with MSI and ASUS options.

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

Roughly 140 pixels per inch brings exceptionally crisp graphics and removes most of the text-fringing concern from earlier QD-OLED generations.

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

The semi-glossy finish produces a clean, striking image with minimal matte grain. Its reflections, smudges and cleaning sensitivity are the tradeoff.

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

The general verdict is highly enthusiastic about image quality and gaming responsiveness. Buyers still debate the curved format, feature omissions and upkeep.

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 QD-OLED coverage makes rich reds and greens stand out and supports demanding color spaces. Unclamped SDR content can look exaggerated.

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

The absence of integrated speakers means separate audio equipment is necessary, an inconvenience for meetings and quick video viewing.

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 port are handy for peripherals, but the hub cannot replace a full docking solution.

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

User-installable firmware has added welcome Dolby Vision controls and other refinements. Updates cannot be assumed to solve every latency or color issue, however.

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

Extremely low processing delay makes actions feel immediate, with fast 240Hz response especially compelling for games.

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

Follow-up owners describe excellent continued enjoyment and reassuring burn-in results, with some quirks around wake behavior and vulnerable coating.

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

The stand clicks together without complicated tools, making first-time assembly and cabling relatively painless.

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

Three years of burn-in coverage is reassuring, but a detailed owner account reports frustrating treatment over coating damage not covered by warranty.

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

Two full-bandwidth HDMI 2.1 ports provide dependable 4K high-refresh connectivity for computers and current consoles, a major advantage over limited HDMI implementations.

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

For high-end OLED gaming, reviewers often find the performance compelling, especially at discounts. Similar flat monitors can supply more ports for the price.

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

A centered joystick makes menus quick to access and largely intuitive, although the many HDR modes and buried calibration controls complicate settings.

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

The active cooling fan is usually unobtrusive or virtually inaudible, although ultra-quiet PC users may still prefer passive cooling.

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

Dark Stabilizer can reveal more shadow information, but higher settings lift blacks enough to undermine the signature OLED look.

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

Per-pixel OLED lighting delivers exceptional light-to-dark separation without conventional backlight halos, especially impressive in dim rooms.

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

Adaptive sync generally minimizes tearing and supports smooth gaming at fluctuating frame rates, although OLED VRR flicker is not entirely eliminated.

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 delivers the full high-resolution refresh-rate experience with compression, though the lack of a newer high-bandwidth connection or optional DSC disablement disappoints some enthusiasts.

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.

Stable SDR brightness makes ordinary desktop work less distracting than on older OLEDs. Some preset modes still dim real-world content, and HDR highlights fluctuate with scene brightness.

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

The sRGB Creator mode often measures exceptionally well, with true-to-life results. Default wide-gamut oversaturation and some poorly configured presets temper the praise.

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

SDR brightness is enough for most controlled rooms but modest beside bright LCDs. HDR can deliver much stronger small highlights than full-screen white scenes.

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

The combination of razor-sharp 4K detail, vivid color and OLED blacks produces a striking image. Room lighting and HDR presets influence how close it gets to its best.

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.

The standout strength is excellent per-pixel HDR contrast, rich color and high-impact highlights. Maximum brightness on large bright areas is lower than good mini-LED displays, and preset behavior matters.

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

The missing KVM switch is a frequent complaint when comparing similarly priced alternatives, especially for swapping between computers.

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.

The QD-OLED panel keeps saturated colors impressively bright, making highlights vivid without relying entirely on white brightness.

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

Custom Color offers useful adjustments, but certain Creator and HDR modes lock controls or place them awkwardly. The degree of flexibility falls behind some competing monitors.

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

HDR10 can be very accurate in the better presets, but Peak 1000 and Dolby Vision configurations produce conflicting judgments over crushed detail, lifted brightness or early roll-off.

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

The sturdy stand and well-assembled chassis generally feel appropriate for a premium monitor. A few find the plastic-heavy housing less special than metal rivals.

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

Alienware’s two-tone white-and-black styling earns considerable praise, though tastes differ on the plastic finish and futuristic accents.

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

Thin surrounding borders keep attention on the OLED panel, with a more noticeable Alienware-branded lower edge.

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

The 32-inch canvas is especially engaging for 4K games and useful for split windows, although desk space and competitive peripheral visibility may be concerns.

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

Some users report comfortable extended sessions and little visible flicker, while the low-blue-light and on-screen comfort controls are relatively sparse.

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 accurate sRGB tuning is a bright spot, but individual presets require gamma corrections or show darker-shade tracking errors.

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

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

The lack of a black-frame insertion mode is a missed option for those who want additional perceived motion sharpness at lower frame rates.

The very accurate sRGB mode and strong results after software profiling are reassuring for careful image work. The less convincing DCI-P3 preset and lack of hardware calibration are caveats.

One extended technical test found the picture drifted substantially after startup, with colors appearing washed out even after prolonged warm-up. This was a specific unit report rather than a universally observed problem.

The gentle 1700R curve adds a little involvement without feeling extreme to many users. Others prefer flat screens, especially for straight-line desktop work.

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 glossy finish can show smears and bluish cleaning streaks readily; owners who touch or wipe the display often may find its delicacy frustrating.

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

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

Missing or limited conventional audio-out connectivity frustrates users with wired speakers or headphones; HDMI eARC helps soundbar setups instead.

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

Internal active cooling does not appear intrusive in normal use and keeps the premium panel operating quietly.

The sRGB Creator profile is generally a strong, usable choice. DCI-P3 targeting and default gamma settings have been much less consistent.

The shipping materials and tool-free assembly are generally practical, though the delicate glossy panel deserves careful handling during unpacking.

A long-term owner reported temporary lines disappearing after panel maintenance, with no visible residual burn-in afterward.

A bright full-white desktop can draw considerably more power than an efficient IPS screen of similar size, although mixed scenes are less demanding.

HDMI 2.1 enables the high-quality 4K 120Hz experience that makes this panel an attractive PlayStation display, with excellent contrast and response.

Automatic HDR format handling can be convenient with streaming devices, but Windows Dolby Vision behavior and disruptive resyncs complicate PC transitions.

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

Ordinary wake-up operation is generally reliable, but isolated input-switching and HDMI brightness-reset problems have been reported.

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

The HDMI audio-return connection is a welcome rarity on a gaming monitor, especially for a soundbar or receiver. Most setups worked, although a few reported connection or Atmos difficulties.

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

Owners repeatedly warn that the glossy surface is difficult to wipe without leaving streaks or marks. Cleaning requires care, and this is a meaningful practical drawback.

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.

Dolby Vision helps compatible Xbox and streaming content look especially rich. Windows has caused incorrect automatic mode selection, though a firmware toggle offers a useful workaround.

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

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

Ordinary operation is generally comfortable with little visible flicker, but some dark scenes or variable-refresh conditions can reveal minor luminance fluctuations.

The surface can be uncomfortably easy to mark or scratch, and even microfiber cleaning has caused complaints from long-term owners.
