Compare Samsung Odyssey OLED G80SH S32HG802S vs KOORUI S2741LM

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

A built-in KVM makes it practical to share peripherals across connected computers, with reliable Mac/Windows operation reported.

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

Switching modes is simple with a dedicated button, but toggling while a game is already running has caused a PC freeze.

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 joystick is intuitive once located, but buried options, repeated navigation and an easily hit mode button add friction.

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

The shadow-boost control can reveal darker content, although raising it too far washes out blacks; a slight negative SDR adjustment can improve perceived contrast.

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.

Unusually high SDR and large-scene HDR brightness makes the screen stand out, especially in daylight. Very small bright highlights are less striking than the peak figures suggest.

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

Well-configured gamut modes and profiling can look excellent; native colors may be oversaturated and HDR tones sometimes shift red.

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.

Its 1,152-zone Mini LED backlight brings strong HDR brightness and contrast, but dark-detail crushing, red-leaning color and muted tiny highlights divide opinion.

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

VRR works across the refresh range without the obvious flicker sometimes seen on competing panels.

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

With local dimming enabled, contrast becomes far stronger than ordinary IPS and the scene looks punchier. Disabling dimming returns it to typical IPS contrast.

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.

Richly saturated images and outstanding large-scene brightness make it striking, but aggressive dimming is not ideal for every scene.

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

Bright saturated colors have impressive punch in games and HDR scenes, giving even muted scenery surprising vibrancy.

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

Controlled testing reported no visible VRR-induced flicker, even though separate 60Hz local-dimming flicker can occur.

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

Strong peak brightness does not extend to the smallest HDR highlights, which can be substantially dimmed to prevent blooming.

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

One test found laptop wake reliably handled, while an owner complained that the backlight remained lit in standby.

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

The monitor reliably recognizes connected computers after sleep, typically taking several seconds to display their picture.

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

Typical IPS breadth is compromised by off-axis glow and brightness shifts, especially with local dimming in darker scenes.

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

Halos are relatively modest from directly ahead but become noticeable off-axis or around small bright shapes on dark backgrounds.

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

Motion is generally clean at 160Hz, though inverse overshoot at lower refresh rates and smearing at 320Hz remain drawbacks.

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

Power draw can be high at maximum brightness while charging a laptop, although everyday brightness settings reduce consumption substantially.

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

Testing found generally even lighting, but another owner noticed edge darkening and some scene-dependent color shifts.

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

An LCD Mini LED panel avoids the burn-in anxiety associated with static work on OLED displays.

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

A substantial base keeps the screen fairly steady with little wobble, and the construction feels better than its price suggests.

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

The Game preset generally beats the Movie preset by showing more shadow detail and brighter scenes; the alternative can crush dark tones.

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

There is a useful choice of game and image modes, though the best contrast and HDR results often require some experimenting.

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

The IPS LCD uses a conventional RGB stripe for clear text and avoids OLED burn-in, though native blacks and off-axis glow remain IPS-like.

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

PC gameplay benefits from bright 4K and a high-speed alternative, but more responsive OLED models remain attractive for competitive-only buyers.

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

At 160Hz motion is generally crisp; the 320Hz mode can smear and its strobing option adds clarity at the cost of extra setup.

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

Good 160Hz pixel response keeps blur reasonably low, but transitions cannot fully keep pace with 320Hz and overshoot rises in aggressive modes.

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

There are no integrated speakers; anyone relying on monitor audio will need headphones or external speakers.

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.

Two downstream ports provide useful peripheral connectivity, though their speed and limited count earned differing assessments.

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.

The 1080p/320Hz image is playable rather than perfectly pixel-mapped; gradient and fine-detail artifacts appear more noticeable in slower games.

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

Dark detail varies by preset: the Game HDR mode and gentle shadow tweaks reveal more, while Movie and some gamut modes crush blacks.

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.

The 1080p/320Hz mode makes fast multiplayer enjoyable, but softer detail and residual smearing mean speed does not equal perfect clarity.

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.

HDMI 2.1 and 4K/120Hz support make current consoles easy to use; occasional 60Hz dimming flicker remains a caveat.

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 3.5mm audio output offers a handy way to route sound through the display and simplify desk cabling.

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

Supplied video and connection cables make it easier to set up without buying separate leads.

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

The easily removed stock stand exposes standard 100×100mm VESA points for a monitor arm.

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

Native 4K and forceful HDR brightness make detailed single-player games a strength; the 160Hz setting is generally favored over low-detail 320Hz for cinematic play.

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

Support spans common variable-refresh formats and the full gaming modes; certification status and detailed behavior vary.

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

A stand channel and rear connection cover can hide cabling neatly, although the cover and narrow exit space can be fiddly.

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.

The mix of HDMI 2.1, DisplayPort, USB-C, USB-A and audio output covers gaming PCs, consoles and laptops well.

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

Height, tilt, swivel and portrait rotation are smooth and extensive, making long desktop sessions easier to position.

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.

90W USB-C charging and video simplify laptop connections, though very power-hungry laptops may still drain battery.

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

The rear RGB ring adds a clean accent without overpowering the setup, and it can be switched off for an understated look.

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

A broad Adobe RGB gamut and strong calibrated results suit photography, including HDR image work, but factory profiles are absent.

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.

Sharp native 4K gives more detail to games and desktop text; choosing 1080p for 320Hz deliberately trades away that crispness.

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

Native 160Hz feels fast for 4K gaming, while the 320Hz option offers extra speed at the expense of resolution.

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

One owner found the monitor noticeably cooler than their other 4K displays at similar brightness settings.

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

At 27 inches, 4K provides finely rendered text and detailed games, a noticeable improvement over more common 1440p screens.

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

The dense 4K panel makes fine detail and text notably sharper than standard 27-inch 1440p alternatives.

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.

Users and testers largely admire the bright 4K image and flexible refresh options, while noting local-dimming and color setup quirks.

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.

Local dimming gives darker blacks than ordinary IPS, though KOORUI sometimes prioritizes brightness over the deepest possible blacks.

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

Measured input lag is low even at 60Hz, and gaming controls feel responsive across refresh settings.

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

A light matte coating suppresses bright reflections while preserving clarity, helping in lamp-lit rooms.

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.

Wide Adobe RGB and DCI-P3 support adds reach for photography and makes media colors vivid, although correct profiling still matters.

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

FPS counters, game modes, a shadow boost and strobing provide useful gaming extras beyond basic refresh settings.

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

The 320Hz mode reduces resolution, but reaching something close to 320fps still depends heavily on the game and graphics hardware.

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

Color presets clamp the wide gamut effectively, but the restricted RGB, gamma and temperature settings can frustrate fine tuning.

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

HDR EOTF tracking is mostly consistent but somewhat too bright in darker content, limiting strict accuracy.

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

HDR brightness remains adjustable, but missing color and black-equalizer controls can make shadow and highlight tuning frustrating.

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

Default gamma is close to target and can bring out dark tones, while some alternative color modes lose near-black detail.

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

Slim bezels look modern, but one owner noticed brightness falling away at the screen edges.

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-care and e-book modes are available, but their appeal is limited by the lack of a meaningful dedicated low-blue-light preset in other testing.

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

The monitor feels reassuringly solid for its price, with a stable metal-based stand and little creaking or wobble.

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

The dark, restrained chassis works in a home office or gaming room, while the optional rear LED ring supplies understated flair.

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

This 4K/320Hz Mini LED feature set earns strong value praise at competitive prices; OLED and other Mini LED discounts can change the calculation.

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

Two full-bandwidth HDMI 2.1 inputs help the panel handle modern console resolutions and high refresh rates.

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

The included stand assembles quickly and is easy to position without extra tools or hassle.

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

DIC can make moving objects clearer with little crosstalk, but it requires VRR off and resets brightness and overdrive settings.

Careful calibration can deliver excellent measured accuracy, even though the provided factory workflow and missing ICC profile make setup less convenient.

The compact stand base leaves useful desk space for a keyboard, mouse and small riser instead of dominating the desktop.

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

Native 4K at 160Hz is sharp for detailed games, while 1080p at 320Hz prioritizes competitive speed. The faster mode sacrifices detail and can expose motion or switching quirks.

The large external power brick is an inconvenience, although its long cable and relatively cool-running screen soften the drawback.

Firmware updates are possible, but publicly available update packages were not readily found on the manufacturer site.

Factory calibration is undermined by the lack of downloadable ICC/ICM profiles; owners can get good results by profiling the display themselves.

A faint zone flicker can appear around moving details at 60Hz, with some owners finding it intrusive during console gaming.

A Mac and Windows test found reliable KVM switching and wake handling, making the monitor viable for Apple-based desks.

Fast is the safest general-purpose choice; Fastest can add distracting bright and dark overshoot, especially as refresh rates change.

The box presentation and included cable kit made an unusually good first impression.

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

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

The panel supports the 4K/120Hz signal expected from PS5, and reviewers report good console compatibility overall.

A discussion reported stock disappearing unexpectedly, so finding the model has not always been straightforward.

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.

Windows-side HDR toggling can simplify switching, and one owner successfully kept the screen in HDR using brightness utilities.

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

Rear-facing ports are awkward to reach, and the cable cover creates a tight space for connecting leads.

4K/120Hz console content works, but 4K/24Hz input is not supported, which may matter for some film sources.

At 60Hz, local dimming can flicker around moving elements, making frame-rate-limited console games less dependable than high-refresh play.

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.

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.

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

High-zone-count backlighting creates strong HDR contrast but can dim small highlights and low-contrast desktop text.

No coil whine was audible from either the screen or power brick in a quiet workspace.

PiP and PbP let two video sources share the screen, adding welcome flexibility for multi-device desks.

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

PC use was reported as stable, with no black-screen or reset issues during testing.

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

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

90W USB-C power is sufficient for many laptops, but some high-end systems can draw more and slowly discharge under load.

The backlight was measured as flicker-free without PWM, including when local dimming was active.

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