Compare LG 27GX790A-B vs Samsung Odyssey OLED G80SH S32HG802S

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

Dropping the former Tizen smart-TV layer simplifies everyday operation, with a familiar PC monitor menu in its place.

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

AI upscaling clearly improves 720p and 1080p sources, while 1440p gains are smaller. It needs the display to receive a truly sub-4K signal and can look sharpened.

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

USB-C can carry a picture, peripheral data and up to 98W of laptop charging. Some high-power laptops may still need their own adapter.

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

The OLED panel exhibits highly even color and illumination without familiar LCD backlight problems.

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

A spacious sharp desktop and easy laptop docking make the monitor capable beyond gaming, while OLED text and static-content caveats remain.

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

4K detail keeps textures, edges, and distant game objects crisp across the 32-inch screen.

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

The base feels stable in normal use, but light contact can make the whole monitor visibly vibrate.

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.

The 4K panel renders fine game textures and desktop detail exceptionally well. It is a striking step up for anyone coming from a lower-resolution display.

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

There are useful gaming and HDR picture modes, with DisplayHDR singled out as a strong starting point for tuning.

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, two HDMI 2.1 inputs and USB-C video/charging make this a particularly flexible premium monitor. Missing KVM limits shared-peripheral switching.

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 high pixel density minimizes subpixel artifacts at normal distance, but slight green or magenta edges remain visible around some close-up text.

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.

Achieving the full 4K/240Hz experience takes a strong gaming PC and suitable connections, while older DisplayPort hardware may need DSC.

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

PlayStation 5, Xbox and Switch 2 are well served by 4K, HDR and modern HDMI support. Console output tops out below the monitor’s full 240Hz capability.

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

A DisplayPort cable and USB-C cable are useful inclusions, though an HDMI 2.1 cable is absent from one tested package.

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

The 32-inch 4K panel makes individual pixels and minor text fringes hard to see from a normal seating distance.

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

The matte Glare Free treatment diffuses direct window and lamp reflections far better than many glossy OLED competitors.

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

Blacks look exceptionally deep in dark rooms, yet can take on a purple cast under strong ambient light. Some HDR configurations also crush the nearest dark shades.

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.

Crosshair overlays, black equalizer, adaptive sync and other gaming tools give players plenty of customization choices.

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

The matte finish is excellent at softening reflections but adds haze and grain compared with glossy QD-OLED rivals. A few users find the texture intrusive.

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

Common adaptive-refresh standards are supported, which is helpful for changing frame rates. Dark-scene flicker means compatibility is not always trouble-free.

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 two USB-A ports can serve connected peripherals, and compatible USB-C devices can use the hub through a single cable. Data bandwidth may trade off against maximum video mode.

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

Rich, vibrant QD-OLED color is a major strength, with broad coverage for games and creative work. The lack of a dedicated sRGB clamp may make standard content too saturated.

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

The supplied stand adjusts height, swivel, tilt and pivot over a useful range, making ergonomic positioning straightforward.

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

Fast-moving elements show almost no noticeable smearing, helping demanding action games stay legible.

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

Color range and 4K sharpness suit photo work, with calibration advised where exact tones matter.

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

Near-black adjustment can reveal hidden dark areas, but too much lifting washes out blacks and some HDR configurations still crush detail.

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

Deep shadows, vibrant HDR lighting and detailed 4K scenes make cinematic games exceptionally immersive. Some HDR modes need care to avoid crushed blacks.

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

Controls feel immediate with very little input delay. The optional flicker-reduction setting can add substantial latency, however.

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

There are no integrated speakers, a disappointing omission for anyone who wants quick audio without external equipment.

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

Small reflections, light sources and other bright details pop with convincing intensity, lending dimensionality to HDR scenes.

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

Slim proportions, a minimalist finish and metal details give the hardware a polished, upscale impression.

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

Frame-rate fluctuations can cause distracting flashes in dark games. Stabilizing settings may mitigate this, with possible added input lag.

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

Pixel refresh, static-logo dimming, screensaver and active cooling give owners several safeguards. None removes the inherent risk of prolonged static images.

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

An especially compelling pairing for high-end PCs: 4K detail, 240Hz motion and dramatic OLED contrast come together in one screen.

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

Near-instant OLED pixel transitions produce exceptionally clean action, even where lower frame-rate console output limits the refresh rate.

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.

Sharp 240Hz motion, near-instant response and low lag make it a strong option for fast competitive games. VRR flicker controls can introduce unwanted latency.

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

Rapid action stays sharp with minimal blur, making fast-paced games unusually easy to follow.

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

The balance of outstanding OLED gaming and modern inputs earns enthusiastic praise. The matte finish and bright-room black behavior are its most divisive compromises.

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

The rear Core Lighting ring offers pleasant customizable ambient light and screen-synced effects, though broader PC-lighting synchronization is limited.

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

A pass-through opening in the stand tidies power and signal cables, while USB-C docking further reduces desk clutter.

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

The latest Tandem QD-OLED panel combines near-perfect blacks with more brightness and improved efficiency than earlier OLED generations.

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

At 240Hz, motion is notably fluid, particularly in fast PC games. Fully exploiting that ceiling requires a PC capable of delivering high frame rates.

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

Standard 100 × 100 mm mounting allows an arm or wall mount instead of the bundled stand.

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

Color and contrast remain very consistent from the side, making the screen easier to share than many LCD alternatives.

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

HDR offers many detailed settings and two tone-mapping approaches, but dialing in shadows and brightness can become frustrating.

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

Static mapping better preserves the intended light balance; Active looks livelier but can lift midtones and alter bright detail. Some peak modes crush shadows.

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

Samsung’s official Windows driver and color profile are useful for proper device recognition and configuration.

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

White balance, gamma and color-space controls allow fine tuning, and measured color error can fall substantially after calibration.

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

The physical frame is thin, but the inner black border remains more noticeable than its sleek outer edge suggests.

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

The 32-inch format gives games and complex tasks room to breathe, though it is a substantial desktop display.

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

The blue-light-reduction setting is useful for late-night reading, but its warmer output is not ideal for accurate colors or HDR games.

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

The slim silver-and-black housing looks clean and understated rather than aggressively gamer-styled, with optional rear lighting.

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

Metal-backed construction and a tidy finish feel robust and high-end, although one hands-on assessment found the stand easy to wobble.

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 is powerful enough for uncompressed 4K/240Hz on compatible hardware. One owner reported intermittent DP signal dropouts that did not occur over HDMI.

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

Shadow controls can bring hidden dark objects into view, but aggressive settings wash out the contrast that makes OLED attractive.

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 layer maintains vivid saturation even as bright HDR elements intensify, keeping colorful scenes energetic.

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

There is no integrated KVM switch, so moving one keyboard and mouse between computers is less convenient than on some rivals.

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

The newer panel is brighter than its predecessor and retains luminance well as brighter areas grow. Full-screen white is still less intense than small HDR highlights.

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

FreeSync and G-SYNC-compatible variable refresh help smooth inconsistent frame delivery and reduce tearing, though dark-scene flicker is still possible.

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.

One owner experienced HDR brightness settings failing to persist across sleep, wake and restarts.

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.

Small bright highlights glow against true OLED blacks, creating dramatic HDR images. Some high-brightness modes can lose shadow detail or alter highlight tone mapping.

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

A conventional joystick menu makes key settings accessible and avoids Samsung’s older smart-TV interface. The compact layout and abundance of picture settings still take learning.

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

A crisp, vivid 4K OLED image with convincing depth is the defining appeal. The coating and room lighting strongly influence perceived clarity and black levels.

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.

Larger bright scenes retain more output than on earlier OLED designs, although brightness limiting has not disappeared entirely.

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

Color looks attractive and often fairly accurate out of the box, but some tests find oversaturation and imperfect factory calibration. Careful adjustment improves accuracy.

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

Self-emissive pixels deliver striking contrast without the elevated blacks or halos typical of many backlit monitors.

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 is imperfect before calibration, so exact tonal accuracy may require additional tuning.

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

Normal-use burn-in coverage is reassuring, although eligibility and coverage terms need verification for the exact regional unit.

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

Two HDMI 2.1 inputs accommodate modern consoles and other fast video sources, including 4K at 120Hz console modes.

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

It asks a premium over basic OLED monitors, but its newer panel, refresh speed and connectivity make a reasonable case for enthusiasts.

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

An owner reported intermittent DisplayPort blanking that disappeared after switching to HDMI; longer-term panel reliability is not yet established.

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

The stand clicks into place and the base screw can be tightened without tools, making initial assembly simple.

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.

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

Bright objects retain clean borders against pitch-black backgrounds, without the halos that can surround highlights on local-dimming LCDs.

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.

Desktop PCs, compatible laptops, DeX tablets, PlayStation 5 and Switch 2 all receive useful display features, though modes vary by device.

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

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

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.

Static tone mapping serves accuracy, while Active boosts perceived brightness and impact; both have useful but distinct roles.

The 3.5 mm jack provides a useful connection for headphones or external speakers when no built-in audio is available; sound quality itself is not evaluated.

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

Active cooling, thermal monitoring and the metal rear help manage panel temperature as Samsung pushes OLED brightness higher.

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

One owner needed to install the Samsung driver before the monitor was recognized when first connected.

The newer Tandem structure aims for better light efficiency, allowing stronger brightness without the same immediate dimming.

A reported bug resets HDR brightness to zero after sleep or restart, creating a frustrating repeated setup burden.

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

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

With a full UHBR20 connection and compatible GPU, the reviewer verified 4K/240Hz without compression. DSC remains a visually lossless fallback for older links.

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.

Xbox users do not get Dolby Vision on this monitor, so the other available HDR formats become the practical options.

An official driver supplies the correct display identity and color profile in Windows, helping the PC recognize and configure the monitor.
