Compare Samsung Odyssey OLED G80SH S32HG802S vs Samsung Odyssey OLED G81SF S27FG810S

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.

The missing USB-C video and charging connection is an important omission for laptop users. A modern one-cable setup is not possible directly from this screen.

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

Fine gradations in dark scenes remain visible without lifting black levels excessively. This adds depth to atmospheric gameplay.

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

The slim base is reassuringly firm and keeps the panel steady. Some resistance in the adjustment mechanism may even help prevent accidental movement.

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.

HDMI 2.1, DisplayPort and a USB-A hub cover core gaming needs, but there is no USB-C or KVM. A few prefer newer DisplayPort bandwidth at this price.

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

The rear strap keeps basic wiring together, but it is not a full cable-hiding solution. Wall-flush desks can still expose a cluster of cables.

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

The sharp panel is pleasant for general tasks, but competing displays with KVM and USB-C are easier to integrate into a work-first desk.

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

Game and picture modes provide plenty of quick looks and fine-tuning choices. A few settings can produce unnatural color or require adjustment.

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

Core gaming tools are present, but the extras feel sparse compared with some rivals. The display prioritizes picture quality over convenience features.

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

Adaptive refresh supports smooth PC and console play across variable frame rates. It is particularly useful when a game cannot hold a steady 240fps.

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

4K at 240fps is a demanding target even for powerful graphics cards. Much of the monitor’s headroom can go unused on midrange systems or in maximum-detail AAA games.

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.

Lower-than-4K material generally scales cleanly and can be sharpened to taste. Pre-480p sources are a notable exception.

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

HDMI and DisplayPort cables, power hardware and the stand make initial setup convenient. The included connections cover a typical desktop gaming arrangement.

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

Cooling and static-element dimming are thoughtful OLED-care features and do not interrupt normal gaming often. They reduce risk rather than guarantee permanent immunity.

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

Samsung’s thermal system draws praise for running cool without noisy fans or intrusive maintenance. It is a distinctive strength of the design.

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.

Deep, near-perfect blacks bring dark scenes to life when ambient light is controlled. In brighter spaces, the QD-OLED panel can make those blacks look purple or raised.

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

Uneven frame pacing can trigger distracting brightness flicker in dark scenes with VRR Control disabled. The mitigation setting may help, though it is not guaranteed to cure every game.

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 USB-A connections provide practical peripheral access, including useful powered-port scenarios. They are welcome but do not replace a laptop dock.

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

Compatible monitor arms offer more positioning options and free up desk space. The standard mount complements the adjustable stand.

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.

A striking gaming display whose picture quality and responsiveness win strong praise. The high hardware demands, premium cost and missing convenience extras stop it from being an automatic pick.

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.

Quick pixel response, low input lag and a 240Hz ceiling make it excellent for fast shooters and esports. Players prioritizing the very highest frame rates may prefer a lower-resolution, faster screen.

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

Height, tilt, swivel and portrait rotation provide welcome flexibility. One owner found the movement stiff, but generally the support is stable and versatile.

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

The rear light ring adds a customizable, softly glowing backdrop for gaming. It is most visible near a wall in a dim room and may seem subtle elsewhere.

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

Controls feel immediate, with particularly low lag at high refresh rates and strong responsiveness even at 60Hz and 120Hz. That helps both PC and console play.

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.

4K, HDR, VRR and strong 120Hz responsiveness make modern consoles look excellent. The 240Hz maximum is largely unused, and separate audio is needed.

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

The matte finish effectively diffuses window and lamp reflections rather than producing mirror-like glare. That advantage comes with some extra perceived grain or haze.

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 240Hz ceiling makes fast PC gaming beautifully fluid, with ample room for esports frame rates. The benefit is less substantial when demanding 4K games run far below 240fps.

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

Games and photos look strikingly crisp at native 4K. The matte coating and some text-scaling preferences can make white desktop elements look softer to sensitive eyes.

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.

The coating divides opinion: reflections are greatly subdued, but light backgrounds can look grainy or slightly diffused. Glossy alternatives have a cleaner appearance in controlled lighting.

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

Individual OLED pixels keep highlights from spilling light into neighboring dark areas. Subtitles, stars and high-contrast scenes stay clean.

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

There are no onboard speakers, so even simple notification sounds require headphones, a soundbar or external speakers. This can be frustrating at the price.

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.

Vivid, wide-gamut colors are among the monitor’s best qualities, making games and creative visuals look lively. Saturation is especially impressive in colorful HDR scenes.

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

Small bright objects stand out sharply against dark surroundings, adding depth and sparkle. Overall HDR intensity is constrained in very bright scenes.

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 headphone jack provides a simple way to route audio through external equipment. It can also help create a tidy soundbar arrangement.

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

Fast movement stays exceptionally clean, with little blur or smearing. Even lower frame rates can feel responsive thanks to the OLED panel.

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

QD-OLED delivers superb blacks, intense colors and extremely fast motion, giving the display much of its appeal. Its light sensitivity and OLED maintenance needs are real tradeoffs.

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

A powerful gaming PC can take full advantage of the sharp 4K image, fluid refresh and low-latency response. Less capable systems may be better matched to a cheaper 1440p OLED.

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

Detailed 4K images and rich QD-OLED color work well for graphics and photo editing. Exact tonal decisions may call for careful calibration and coating preference.

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

At around 166 pixels per inch, tiny details, text and textures look unusually well defined for a gaming monitor. The close-packed pixels are a major benefit over similarly sized 1440p screens.

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

Lower brightness settings can reduce eye strain and power bills, although efficiency is not the main appeal. High refresh and vivid OLED performance remain the priority.

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

Metallic silver finishes, tidy lines and restrained details help the screen feel expensive. The stand and housing stand out against plainer plastic alternatives.

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.

Packing 4K into 27 inches produces fine gaming detail, crisp graphics and a sharp desktop. It takes a powerful GPU to combine that resolution with very high frame rates.

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

The rapid OLED pixel transitions preserve detail during quick camera movement and high-speed action. It is a standout strength across gaming modes.

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

OLED blacks, vivid color and sharp 4K details make story-driven and atmospheric games immersive. High graphical settings will still challenge the fastest PCs.

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

Fine pixel density minimizes visible OLED text artifacts for some, but others notice colored edges on small high-contrast text. Matte diffusion adds another sensitivity-dependent variable.

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

Colors and contrast remain strong from wide angles, without the obvious washout of many LCDs. That makes the image dependable off-axis.

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.

DisplayPort 1.4 with compression can carry the full 4K/240Hz image, but some buyers expect DisplayPort 2.1 in this price range. Actual picture clarity is not a major complaint.

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

Colors generally look pleasing and capable of supporting creative work. Some tuning and preset choices can matter when precision is more important than impact.

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

Adjusting shadow lift can expose opponents in dark areas without increasing overall brightness. It takes experimentation to balance visibility against accuracy.

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.

Highlights can look vivid, and many find everyday SDR brightness sufficient. Sustained bright HDR scenes fall short of brighter LCD or mini-LED options.

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

FreeSync and VRR help keep action smooth when frame rates fluctuate. Some setups may require tweaking VRR Control because flicker can be noticeable.

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.

The simple menu is responsive and straightforward for some, but the rear control is awkwardly located and disliked by others. Controls are more divisive than the picture.

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

There is no integrated KVM to share one keyboard and mouse between computers. That is especially disappointing for multi-device workstations at this price.

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

Compression over the available ports is described as visually transparent, with little visible difference between HDMI and DisplayPort. It enables high refresh without noticeable image loss.

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.

Bright accents against OLED blacks make cinematic HDR compelling, especially in darker rooms. Peak-brightness limits and finicky tone mapping keep bright scenes from being equally spectacular.

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

Quantum-dot color looks impressively saturated and luminous, especially in vibrant game environments. Intense hues remain a major visual attraction.

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

Pixel-level lighting creates dramatic separation between bright highlights and truly dark areas, without LCD-style halos. Games gain a strong sense of depth.

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

One test encountered several seconds of black screen when changing between games with different demands. It can be jarring even though gameplay picture quality is excellent.

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.

The 4K QD-OLED image looks intensely detailed, colorful and contrast-rich, particularly in games. Matte haze and a few HDR brightness tradeoffs can temper the effect.

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

Short-term operation was trouble-free without burn-in or other issues. Longer ownership still depends on static-content habits and OLED care.

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

Assembly is quick and generally straightforward, with simple click-and-twist fittings. The mechanism can take a moment to figure out the first time.

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

Exceptional visuals and speed justify a premium for the right gamer, but the original high price competes poorly with similarly capable rivals. Sale pricing makes it markedly more attractive.

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

The HDMI connections are well suited to 4K/120Hz consoles and high-refresh PC sources. Multiple ports simplify switching gaming devices.

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

There is plenty of control over brightness, tone mapping and color, allowing users to refine the image. The number of interactions needed to find a satisfying HDR mode can be a nuisance.

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

Granular color and white-balance settings make it possible to tune the picture to taste. They offer useful flexibility beyond the defaults.

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

Some scenes look spectacular, but dynamic processing can change brightness too aggressively or leave other parts too dark. Manual settings may produce a more consistent image.

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

The thin-edged screen looks modern, though the silver trim can be more noticeable in a bright room than dark bezels. It is mostly a preference issue.

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

The 27-inch format packs remarkable detail into a desk-friendly footprint. Some prefer the larger 32-inch version for greater immersion.

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

The thin metallic housing and sturdy stand give this monitor a solid, upscale construction. Its slimness does not undermine the overall feeling of quality.

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

The sleek metal look and nearly frameless panel are a strong visual draw. Lighting accents add a subtle gaming touch without dominating the design.

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

Eye-saver and flicker-reduction settings are welcome options for longer sessions. They complement the glare-reducing finish.

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

Multiple virtual aim points can help shooters with difficult aiming situations. The feature is a useful extra rather than a reason to buy by itself.

Pixel-level OLED lighting avoids the unwanted edge glow seen on some LCDs. Dark areas stay convincingly dark.

There is no built-in BFI mode, but an external scaler can enable effective low-frame-rate clarity enhancements. That workaround adds complexity and can cost brightness.

Rich billion-color reproduction gives pictures smooth, natural transitions and bold hues. It supports the monitor’s expressive visual quality.

A slim screen and relatively flat, tidy stand work well on standard desks. The 27-inch format avoids the bulk of larger gaming monitors.

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

Firmware can be updated easily from a USB drive through the monitor menu, without needing a PC connection. The process was quick and uncomplicated.

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

Color shifts appear natural and fluid rather than harshly banded. Subtle gradations complement the screen’s wide color range.

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

High-refresh OLED motion is impressively clean, and external BFI can make 60Hz content clearer still. It remains a specialized workaround.

The box is easy to navigate, making the monitor and included parts straightforward to unpack. Initial setup feels approachable.

OLED-care routines did not interrupt normal gaming during extended hands-on use. That keeps upkeep from becoming a regular annoyance.

A clean, defect-free review sample gives a good first impression of the display. Buyers should still inspect their individual panel.

The inspected unit arrived with no dead pixels or visible defects. That is reassuring for its initial condition, not a guarantee for every unit.

The slim, relatively light chassis is easier to reposition than its premium metal look suggests. This matters most if the monitor is moved regularly.

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

The high-resolution panel and fast 120Hz-class response suit PlayStation gaming well. It lacks a few TV-oriented conveniences, including built-in audio.

The lack of a remote frustrates those accustomed to other Samsung monitors. Basic settings must be handled from the rear joystick.

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

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

The special ultrawide view expands the horizontal perspective but puts black bars above and below. A real ultrawide screen is preferable for frequent widescreen play.

Some rear ports are awkward to reach around the stand neck. Cable changes can be less convenient than the specification suggests.

Movie image quality is strong, but certain 24Hz or 50Hz disc outputs from consoles are not accepted. A separate player may be needed for native-rate discs.

Low lag can make 60fps games surprisingly responsive, including console titles. This does not imply all older signal formats are compatible.

A traditional monitor interface replaces Samsung’s TV-style apps and remote. That simplifies PC settings but removes built-in streaming conveniences.

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

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

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

Each OLED pixel independently controls light, keeping bright details sharply separated from dark ones. The result is effectively halo-free contrast.

The fanless approach is effectively silent during use, avoiding a common concern with complex gaming displays. It preserves immersion during quiet scenes.

Picture-in-picture is useful for checking a second source while keeping the main image large. It cannot replace full side-by-side layouts and can feel cramped on 27 inches.

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

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

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