Compare LG 27GX790A-B vs Samsung Odyssey G80HS S32HG80

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

Accurate tracking in some tests cannot fully compensate for limited peak brightness and weak real-scene separation of bright highlights.

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

The IPS panel showed no perceptible VRR flicker even when frame rates changed rapidly.

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

Blacks generally look gray beside OLED and good Mini LED displays, although one test found better native IPS contrast than expected.

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

Its standout trick is pairing exceptionally clear 6K/165Hz work with useful 3K/330Hz gaming, a far less severe resolution cut than 4K-to-1080p dual-mode screens.

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.

Smooth grayscale and color transitions showed little obvious banding in technical inspection.

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

Fast IPS is a sensible choice for sharp text and burn-in-resistant work, but its blacks and motion are less striking than OLED alternatives.

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

The slim body has an understated look, but inexpensive plastic and the joystick prevent it from consistently feeling like a premium-priced display.

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

Fast motion is generally serviceable, but inverse ghosting becomes visible at lower variable refresh rates in 3K mode.

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

The 3K mode looks surprisingly good for a halved-resolution display, while desktop text and older games can expose softness or tiny interfaces.

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

Most testers find typical decent IPS angles, but edge dimming and brightness shifts drove one office-focused owner to return their sample.

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 simulated 24.5-inch view is usable for fast action, but scaling leaves lower resolutions visibly blurrier than the full panel.

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

Samsung provides downloadable firmware updates, but software-based monitor control does not necessarily handle the update process.

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

Shadow and black-equalizer controls can reveal more near-black detail, although they cannot deliver true OLED-like black depth.

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

Fine text, distant game geometry, and high-resolution photographs look exceptionally clean at 6K; switching to 3K sacrifices some of that crispness.

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

Modern graphics hardware with the right HDMI or DisplayPort output can exploit both gaming modes; older cards can fall well short of the advertised refresh rate.

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

The fast mode looks distinctly clearer than 165Hz, but IPS pixel response and low-frame-rate overshoot prevent OLED-like motion clarity.

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.

Its unusual 6144×3456 native resolution delivers a dramatic text-and-detail upgrade, especially for work; the performance cost makes full-res gaming less universally useful.

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

Cinematic games look extremely detailed at native 6K when hardware can cope, but modest HDR and lower performance detract from the spectacle.

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

Pixel transitions are adequate for gaming but not fast enough for perfect 330Hz compliance; careful settings and high frame rates help avoid artifacts.

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

The light matte finish suppresses reflections without much grain, preserving the panel's unusually fine detail.

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

Experiences differ: the horizontal rear ports seem accessible to one user, while another struggled to attach cables by touch.

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 is broad enough for vivid general use and some creative work, yet falls short of wider-gamut OLED and some competing 5K panels.

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 OLED-style long-term static-image burn-in worries, making it appealing for persistent desktop controls and documents.

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

The non-grainy matte coating keeps ordinary glare manageable, though some dedicated work monitors handle bright reflections better.

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

Modern HDMI and DisplayPort connections handle the demanding signal, but missing USB-C and Thunderbolt and a small USB hub reduce workstation appeal.

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

There is no strobing blur-reduction option, a missed feature for players prioritizing maximum motion sharpness.

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

The exceptionally dense 32-inch 6K panel makes individual pixels nearly invisible at normal distance and noticeably improves fine type and imagery.

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.

A couple of USB-A data ports offer basic peripheral connectivity, but the hub feels limited for a premium productivity-capable monitor.

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.

Native 6K gaming can overwhelm even powerful GPUs, making high refresh at full resolution a costly and often unrealistic target in demanding titles.

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

Across the native and fast modes, input lag stays extremely low and controls feel responsive.

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

Height, swivel, tilt, and 90-degree pivot adjustments are repeatedly praised, even by reviewers disappointed with the chassis materials.

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 3K/330Hz mode gives high-frame-rate competitors a viable option, though slower IPS transitions and low-frame-rate ghosting keep it from leading dedicated esports displays.

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

A cutout in the stand lets cables pass cleanly behind the screen for a tidier setup.

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, presets, and a shadow-control option cover the basics, but strobing, some overlays, and advanced multi-input features are absent.

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

High-bandwidth HDMI and DisplayPort cables arrive in the box, making initial connectivity easier even if the supplied DP cable is relatively short.

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

A 4K image can be viewed at native size with editing tools still visible, making detailed photo work easier than on a same-size 4K monitor.

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

There are several genre-based and general presets; the useful all-around modes work well, while genre differences can be quite subtle.

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

There are no internal speakers. Most see that as an omission at this price, though one commentator would rather avoid low-quality monitor speakers.

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 flat base doubles as a convenient place for accessories, but its broad, chunky shape is less ideal on a tight desk.

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

The broad, flat stand generally holds the screen securely; a small amount of wobble appears during some adjustments.

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

Several tests found edge darkening or patchiness on plain backgrounds, while another owner praised the absence of the blue blotches seen on rivals.

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

Combining 165Hz at 6K with 330Hz at 3K brings a fluidity rarely seen in high-density screens, even if actual gaming frames depend on the GPU.

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

A restrained rear RGB ring adds ambient effects without dominating the design, and it can be switched off for a simpler workspace.

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

FreeSync Premium and G-SYNC compatibility make variable-refresh play practical, with no obvious VRR flicker in one detailed test.

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.

Opinions diverge sharply. Some praise accurate, attractive HDR, but the prevailing concern is that a basic edge-lit backlight delivers little of the contrast expected at this price.

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

Its native contrast is good for IPS by some measurements, but cannot compete with OLED black depth; a few assessments rate its dynamic contrast much more favorably.

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

VRR provides smooth gameplay but locks the overdrive setting; the fixed tuning can become troublesome at lower frame rates.

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

The menu itself can be intuitive, yet the rear joystick attracts complaints about location, cheap feel, and awkward quick-switch behavior.

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

A built-in KVM is missing, reducing convenience for buyers who alternate between multiple computers with shared peripherals.

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 changes can be awkward: the joystick cycles through an extra 24-inch option, and one MacBook connection required switching back to HDMI to escape a no-signal dual mode.

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

Adjustable shadow boosting helps uncover dark details in games and films without simply raising the entire black point.

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

Around 440–480 nits is ample for ordinary indoor work but falls short of the impact and flexibility of brighter premium HDR rivals.

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

6K sharpness earns consistent admiration, while weaker contrast, HDR punch, and panel consistency stop the overall image from being an unquestioned class leader.

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

Factory calibration impressions range from excellent to merely adequate, but the display can become very accurate after adjustment.

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 2.1 supports the demanding native mode; older DP 1.4 devices and some Mac configurations encounter substantial refresh-rate limits.

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

Testing generally finds good or excellent gamma behavior, which can improve further with the available calibration controls.

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

Reports conflict: some praise a solid assembly and sturdy feel, while others criticize the basic plastic construction and flimsy-feeling rear joystick.

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

Low-blue-light modes are available, but locked brightness and other restrictions make them frustrating compared with manual color-temperature adjustment.

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

A roomy 32-inch canvas suits high-DPI work and immersive play, although using 6K requires scaling and does not magically expand the physical viewing area.

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

Narrow edges and a modest bottom chin keep the front clean and focused on the image.

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

The restrained, slim black shell suits both office and gaming desks, although reviewers differ on whether it feels polished enough for the price.

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

The unique 6K/330Hz combination can justify a discounted price for specialists, but many reviewers see much better HDR or gaming value in cheaper OLED alternatives.

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

A customer seeking help with recurring image corruption felt Samsung had not clearly escalated detailed troubleshooting to engineers.

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

Two modern HDMI inputs provide high-bandwidth video, though achieving every mode still depends on the source and proper cabling.

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

Tool-free assembly and manageable weight make the monitor reasonably straightforward to install.

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

Separate HDR settings and tone-mapping choices offer useful flexibility, even though the limited backlight constrains the result.

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

Extensive white-balance, gamma, and color-space adjustments let owners correct factory inaccuracies rather than relying on an inflexible preset.

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

HDR luminance tracking can be precise, with optional active tone mapping producing a slight brightness lift at the expense of some midtone detail.

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.

Low IPS glow is a welcome improvement over some competing LCD panels, especially when viewed from off-center.

Black-frame insertion is missing, so motion tuning depends on the refresh modes and response behavior instead.

Fine RGB controls and full calibration can produce excellent SDR color accuracy, even where factory white balance misses the mark.

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

The compact external power brick keeps power hardware outside the panel and can be replaced, though it adds another component to manage.

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

The analog audio output is useful because the monitor has no internal speakers, though its placement is not always effortless to reach.

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

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

The dense screen suits macOS integer scaling, but practical refresh ceilings, adapter requirements, and the lack of Thunderbolt depend heavily on the Mac and connection. One user could not establish DisplayPort video until turning off dual mode over HDMI.

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

Overdrive cannot be adjusted with VRR enabled, causing a frustrating tradeoff between transition speed, tearing avoidance, and inverse-ghosting artifacts.

One owner received a unit with dead pixels and returned it; that individual experience flags quality control without establishing a wider failure rate.

Startup appeared as quick as a normal monitor rather than adding the delay observed on some other 6K displays.

The external power adapter can be swapped without opening the display, a practical maintenance benefit of its design.

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

Remembered brightness settings for each signal mode make transitions between SDR work and HDR entertainment less tedious.

One owner reported static appearing mostly after cold starts and sometimes during normal work, temporarily cleared by changing refresh rates.

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.

No Thunderbolt dock or USB-C video input is built in, so laptop users may need an external hub and additional cables.

The traditional 16:9 shape disappoints someone who would prefer a wider, wraparound field for immersive games.

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

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

Windows' automatic color management can restrain oversaturated SDR colors, though it does not fix every grayscale calibration issue.

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

Dynamic Brightness can boost perceived contrast, although its histogram-based behavior is not equivalent to a physical ambient-light sensor.

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.

Compression is required for full 6K/165Hz operation, but technical testing found no meaningful practical downside to the selected DisplayPort bandwidth.

The minimal edge-lit dimming system seldom adds much real-scene contrast and is the clearest technical obstacle to convincing HDR.

At full 6K on a taxed graphics card, blur made distant targets hard to identify while moving, undermining precise shooter play.

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

Neither split-screen input mode is provided, a notable omission on a large high-resolution panel meant for flexible setups.

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

The rear joystick divides opinion: some find it fast and intuitive, while others dislike its feel, location, and accidental mode switching.

Samsung's desktop utility offers some settings, but important controls are still unavailable through the software.

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

An owner describes intermittent half-screen corruption with certified DisplayPort cables, suggesting a frustrating signal issue on at least one unit.

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

The backlight is flicker-free with local dimming off, while enabling dimming at reduced SDR brightness introduces PWM that may bother sensitive users.
