Compare LG 27GX790A-B vs ASUS ROG Swift OLED PG32UCWM

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

The joystick interface, customizable shortcuts and companion software make the extensive settings more approachable than the feature list suggests.

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 smaller simulated screen size makes competitive play more flexible, but image quality falls as the active resolution shrinks.

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 familiar RGB stripe virtually eliminates the colored borders around text seen on many earlier OLEDs, especially useful for reading and office 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.

Native 4K 240Hz covers detailed games and work; 1080p 480Hz trades definition for outstanding motion clarity, a flexibility multiple testers appreciated.

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

Up to 90W USB-C charging supports compatible laptops and reduces the need for another charging cable.

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

Downscaling to 1080p is comparatively smooth for a dual-mode 4K screen, but smaller emulated windows and operating-system scaling reduce sharpness or complicate text sizing.

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

Firmware can be updated by the user, including through ASUS software, making maintenance more straightforward.

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

The standard RGB-stripe layout and 4K resolution yield razor-sharp images and unusually clean fonts for a glossy gaming OLED.

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 three-pronged stand is stable but takes up considerable desk depth, potentially crowding a shallow workstation or large mousepad.

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

Shadow Boost and an accurate sRGB gamma option recover dark detail, but native-mode near-black tracking can be weak or uneven.

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

Color remains attractive head-on, but greenish edge or off-axis shifts are reported, ranging from barely visible to strongly distracting depending on the tester.

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 occur with large frame-rate swings; ASUS’s anti-flicker setting reduces some cases but can interrupt VRR at certain frame rates.

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.

4K resolution on the 32-inch panel provides rich detail and a large working area, though many users will want operating-system text scaling.

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

Dark-gray banding is modest compared with several earlier Tandem WOLEDs, but some samples show edge darkening, faint dirty-screen effect or tonal shifts.

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

Racing is a strong everyday preset, and alternative color spaces and HDR profiles help adapt the image to different content.

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

DisplayPort 2.1, HDMI 2.1, USB-C and USB data ports provide an extensive connection suite for premium gaming and work setups.

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

The glossy coating preserves clean blacks and sharpness but reflects nearby windows, lamps and faces more directly than matte finishes.

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

The haze-free glossy surface gives unusually crisp text and an almost glass-like picture without matte grain, at the cost of strong mirror reflections.

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 4K at 240 frames per second calls for a powerful graphics card, making the 1080p 480Hz option a useful performance alternative.

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.

The USB hub conveniently accommodates peripheral input devices and supports a cleaner multi-device desk setup.

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

Backlighting and the desk projector add visual flair, though the glow can be too weak for ambient wall lighting and some find the projection excessive.

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

Routing cables through the stand keeps the generous selection of connections manageable without excessive clutter.

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

Static desktop use carries an ongoing image-retention risk despite the built-in OLED care tools and warranty coverage.

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

At roughly 140 PPI, the 32-inch 4K panel keeps text and interfaces crisp and leaves room for productive desktop layouts.

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

An included adapter simplifies mounting to a compatible standard monitor arm, especially when the recessed fixture would otherwise obstruct attachment.

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 can stand out brilliantly against black, but particular presets clip highlights or cap output, requiring deliberate HDR mode choices.

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

OLED Care functions include pixel cleaning, screen shifting, logo handling and a presence sensor. They offer useful safeguards, though they cannot guarantee immunity from burn-in.

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

The novel tandem RGB-stripe WOLED panel solves much of OLED’s font-fringing problem and retains deep blacks, though removing the white subpixel hurts brightness efficiency.

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

The monitor impresses as a fast, sharp flagship, but its expensive pricing and HDR tradeoffs make the buying recommendation less unanimous.

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

Input latency is consistently outstanding in high-speed play, with a particularly quick 480Hz mode and very little processing delay.

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.

Timers, crosshairs, sniper tools and shadow aids accompany the high-speed panel. They are convenient extras rather than the monitor’s main selling point.

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

Sharp 4K detail and calibrated SDR color make photo work practical; specific professional color spaces may require profiling.

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

Solid construction, premium finish and enthusiast-grade controls lend the monitor a genuine flagship character.

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

The broad, substantial base keeps the large screen steady with very little wobble.

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

The available ports were easy to reach and connect during setup.

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

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

Very fast OLED pixel transitions support crisp moving images and a responsive feel in demanding games.

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

Height, tilt and swivel adjustments feel smooth and stable, but the included stand cannot rotate into portrait orientation.

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

A 240Hz 4K baseline provides excellent responsiveness, while the optional 480Hz full-HD mode makes speed the priority for esports.

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.

Switching from sharp 4K 240Hz to extremely responsive 1080p 480Hz gives fast-paced competitive games a meaningful speed and motion advantage.

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

Perfect blacks, vivid color and sharp environmental details are especially attractive for cinematic titles, though bright HDR scenes may look restrained.

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

Near-instant OLED transitions are exceptionally clean at 240Hz, and the optional 480Hz mode improves fast-moving target definition further.

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

Coverage around the DCI-P3 space is generous and a step above older standard WOLEDs, though it falls slightly short of the widest competing OLED panels.

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

Selectable 27-inch and 24.5-inch viewing formats broaden the ways to use the 16:9 screen for faster competitive play.

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

Deep OLED blacks are a standout, and the WOLED design holds black depth unusually well even with ambient room lighting.

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

There are no internal speakers, a notable inconvenience if you want sound without connecting headphones or separate audio equipment.

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

The package includes the cables and mounting adapter needed to get started, plus a protective cloth and other useful extras.

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

The built-in KVM adds flexibility for connecting devices and using the monitor with more than one computer.

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.

Full-bandwidth DisplayPort 2.1 can run 4K 240Hz 10-bit video without DSC on a compatible graphics card, adding useful headroom for high-end PCs.

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.

A direct hardware shortcut helps switch between 4K and high-speed modes, but changing while a game is open can scramble the interface temporarily.

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

Variable refresh generally suits smooth gaming, but the anti-flicker setting creates a narrow frame-rate range where VRR disengages and tearing or judder may appear.

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.

Brightness can shift as bright content fills more of the screen. Uniform Brightness steadies desktop viewing, but sacrificing higher peaks and HDR consistency remains part of the compromise.

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

sRGB and calibrated modes can look exceptionally accurate, but the default wide-gamut SDR setting may oversaturate colors and the boosted HDR setting can distort tracking.

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.

HDR can look excellent in dark, high-contrast scenes, but limited full-screen brightness and imperfect bright-mode tracking keep it behind the best alternatives.

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

The joystick menus are quick and intuitive, with programmable shortcuts for commonly used gaming and picture settings.

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

Large bright scenes and full-screen white are less punchy than on some newer competitors, despite strong small highlights and enough SDR output for many users.

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

Excellent sharpness, color, motion and contrast produce a striking image, although full-screen brightness and some HDR or viewing-angle behavior fall short of perfection.

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

Shadow Boost can reveal detail in dark SDR scenes, and adaptive gaming controls can raise visibility where darker areas would otherwise hide objects.

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.

Removing the extra white subpixel improves the vibrancy of bright saturated colors compared with older WOLED designs, although QD-OLED competitors can still have an edge.

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

Per-pixel OLED lighting creates exceptional contrast and crisp separation between dark backgrounds and bright details, even in moderately lit rooms.

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

A three-year warranty explicitly includes OLED burn-in, providing reassurance despite the technology’s inherent aging risks.

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

Pricing around flagship territory divides opinion: the sharp RGB-stripe panel and feature set impress, but much cheaper 4K OLEDs often deliver comparable gaming thrills.

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

Tool-free assembly and the included cables and adapter make the initial setup straightforward.

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

ASUS companion software can change presets, tune display features and update firmware without relying entirely on the physical menu.

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

Adjustable HDR can substantially increase highlight brightness, but turning it up risks raised shadows and inaccurate tone reproduction.

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

Tone mapping provides rich depth when configured carefully; the brighter HDR modes lift dark scenes beyond their intended appearance.

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

Adjustable RGB, gamma, saturation and color-space settings offer useful fine-tuning; the dedicated sRGB Cal preset is accurate but locks many controls.

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

Grayscale and sRGB gamma track well in calibrated modes, though native SDR shadow reproduction and HDR luminance tracking have inconsistencies.

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

The 31.5-inch viewable screen is immersive in games and spacious for desktop work, although it needs a reasonably generous desk.

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

Uniform Brightness can reduce abrupt shifts in desktop luminance, which helps during extended sessions of static work.

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

The translucent rear shell and ROG lighting look distinctive and premium, although the elaborate gamer styling is not universally subtle.

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

Simulated 27-inch and 24.5-inch windows preserve 480Hz and accommodate a compact competitive field of view, with substantial resolution tradeoffs.

Individual OLED pixels give exceptionally precise light control, keeping black areas dark even beside bright details.

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

Flexible picture-in-picture and picture-by-picture layouts let two sources share the screen, including individually adjustable windows.

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

The self-emissive OLED panel avoids the backlight bleed associated with LCDs, helping dark scenes remain free of unwanted glow.

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

Per-pixel lighting prevents bright objects from creating halos or spill into neighboring dark areas, a clear advantage over zone-dimmed LCDs.

Good factory color can be refined further with RGB adjustment and profiling, with excellent results achieved in the calibrated SDR modes.

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

ELMB sharpens 120Hz or 240Hz motion, but disables HDR and VRR; one latency test found such a large penalty that the mode was not worth using.

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

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

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 HDR presets and an adjustable setting are available, yet the choice largely comes down to accurate but dim True Black or brighter, less accurate tone mapping.

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

Internal heatsinks and a newer power design support cool operation without fans, with hands-on temperature checks finding modest chassis warmth.

An internal power supply avoids a bulky external brick, simplifying installation and cable routing.

Removing the white subpixel increases power use on white-heavy content versus some previous WOLED monitors, with a smaller difference during gaming.

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

The adjustable presence sensor can switch the OLED pixels off when the desk is unattended, with configurable distance, timing and sensitivity.

Automatic Dolby Vision and HDR10 switching can briefly black out the screen, and detection does not work reliably in every PC app.

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

One test found Windows 11 Auto Color Management failed to clamp SDR colors properly, although selecting the monitor’s own sRGB mode provided a workaround.

The power button asks for confirmation, reducing accidental shutdowns, while quick-access controls make everyday operation more deliberate.

DisplayWidget Center provides useful software access to picture settings, shortcuts and firmware, though not every hardware toggle is available there.

Dolby Vision is handy for compatible entertainment sources, but automatic HDR10 detection on Windows can be unreliable and brightness is limited in its Dolby Vision modes.

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

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

A smaller brightness dip than older OLED panels may make the monitor more comfortable for people bothered by display flicker.

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