Compare Samsung Odyssey OLED G80SH S32HG802S vs LG 39GX950B-B

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

Dark-scene detail is generally well preserved, with black-level adjustments available to bring out shadow information.

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

The integrated speakers are a welcome convenience for consoles and occasional listening, though they are not substitutes for dedicated audio.

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

The rear can become noticeably hot after extended sessions, although high heat is understandable for this demanding panel.

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

Different HDR presets offer distinct brightness and saturation looks, although none combines every desirable accuracy characteristic.

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.

AI upscaling can sharpen certain low-resolution console signals, but PC use is inconsistent or impractical and cannot replace modern GPU upscaling.

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 165Hz is fluid for detailed 5K2K gaming, but lower than some flagship alternatives; 330Hz demands a drop to 2560×1080.

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

Useful gaming aids and dual-mode are available, but absent anti-flicker, KVM, and black-frame-insertion functions leave the feature set uneven.

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.

Modern DisplayPort, HDMI, USB-C, and USB-A ports cover many setups, though a missing KVM and certain USB routing limitations temper flexibility.

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

OLED-care options are basic compared with rival premium monitors, and prolonged static desktop content still calls for caution.

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

FreeSync and G-SYNC-compatible operation help limit tearing across a broad range of PC and console refresh rates.

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.

Very low lag and optional 330Hz speed help fast shooters, but the lower-resolution picture and large form factor make it conditional for esports.

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

High pixel density makes text generally crisp, although white-subpixel fringing is still visible to some people; RGB-stripe rivals can look cleaner.

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.

Coverage of modern wide color spaces is extensive, producing vibrant games and HDR imagery even if a few saturated colors remain outside its reach.

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

Most tested samples showed little distracting banding in routine use, though dark-gray banding can vary between panels or modes.

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 small USB-A hub adds convenience, although routing its upstream signal through USB-C may complicate some desktop/laptop combinations.

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.

True OLED blacks look inky and deep, with Tandem WOLED generally retaining their depth under ambient light better than QD-OLED rivals.

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.

Modern consoles work well with the display at 16:9, although their lack of ultrawide output means black sidebars.

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

Driving eleven million pixels at high frame rates requires substantial graphics horsepower, so weaker systems will need major compromises.

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

Instantaneous OLED transitions produce remarkably crisp motion, especially at 330Hz, with some refresh-rate limitations relative to faster OLEDs.

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

The stand is solid enough in ordinary use but the big panel can wobble when touched or operated.

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

Tandem WOLED has surprisingly restrained consumption in full-white usage for a panel this large.

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.

Its cinematic OLED image and unusually useful 39-inch format impress strongly, though price and several feature compromises limit the value proposition.

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

Height, tilt, and swivel help tailor ergonomics; some users found the height mechanism stiff or noted wobble during adjustments.

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

The matte anti-glare coating does a convincing job diffusing reflections, especially for a curved display, though direct sunlight can still distract.

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 matte finish reduces mirror reflections but does not deliver quite the crystalline sheen favored by fans of glossy OLED.

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

Frame-rate swings can cause visible flickering in dark scenes, especially in the 330Hz mode, without an anti-flicker adjustment to mask it.

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

Input lag is very low in the gaming presets and main refresh modes, although certain picture modes and low-rate dual-mode inputs add delay.

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.

USB-C video and up to 90W charging make a convenient connection for compatible laptops and other desk devices.

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

Independent OLED pixels eliminate the halos and backlight blooming that can appear on LCD and Mini-LED screens.

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

The monitor accommodates PC, Mac, and current console connections, even though each uses different optimal display modes.

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

Bright effects look striking and fine HDR details generally remain visible, but aggressive tone-mapping settings can sacrifice accuracy.

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

The fourth-generation Tandem WOLED panel offers deep pixel-level blacks, much stronger brightness than older WOLED ultrawides, and rich color.

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

PC gaming is excellent with a sufficiently powerful GPU, unlocking full 21:9 views, 5K2K detail, and rapid OLED motion.

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

At roughly 143 PPI, this monitor approaches the text sharpness of a 32-inch 4K display while offering much more horizontal room.

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.

The 5120×2160 5K2K resolution is a major upgrade over earlier 39-inch ultrawides, bringing finely detailed games and substantially sharper desktop content.

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

Extremely fast pixel transitions keep moving objects clear with little conventional ghosting or smearing.

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

Fine detail in games and desktop apps is one of its signature strengths, particularly compared with 3440×1440 ultrawides.

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

Atmospheric and cinematic games flourish on the large, sharp OLED, with high contrast and impressive HDR lighting.

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

Mode switching is generally convenient, though one review encountered rare Windows layout problems when leaving dual-mode.

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

The black stabilizer can make dark objects easier to distinguish without unnecessarily lifting the OLED black floor.

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

Colors are impressive overall, but the white-subpixel design cannot match the brightest saturated colors available from some QD-OLED competitors.

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

Uniform brightness controls tame distracting OLED luminance changes, though brighter presets can still dim as content changes.

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 DisplayPort bandwidth allows native 5K2K at the full refresh rate without DSC, whereas other inputs may still need compression.

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 is missing, disappointing those hoping to share peripherals between multiple computers.

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.

Full-bandwidth DisplayPort 2.1 UHBR20 is a standout, capable of 5K2K at 165Hz without relying on compression from compatible hardware.

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

The sRGB and calibrated modes can be accurate, but default wide-gamut settings may oversaturate SDR colors and some presets require tuning.

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 on-screen controls are approachable and the LG software simplifies management, although some menu choices and the interface style divide opinion.

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.

For an OLED ultrawide, brightness is excellent in both SDR and HDR, although sunny windows and larger bright scenes can still expose limits.

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.

Tiny highlights look punchy against OLED blacks and HDR games can be spectacular; mode calibration and full-screen luminance are not flawless.

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

Adaptive sync works smoothly in tested gaming scenarios, helping avoid tearing and supporting variable frame rates.

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

Pixel-level OLED control delivers extraordinary contrast and depth, especially alongside bright effects in otherwise dark scenes.

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.

Image quality is outstanding with razor-sharp detail, brilliant OLED blacks, and impactful color and HDR.

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

High, low, and uniform brightness options provide useful control, but achieving the best balance requires choosing settings for the content.

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

Hardware calibration and selectable sRGB/DCI-P3 presets give unusually flexible options for tailoring color, despite some locked settings.

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 presets trade accuracy against brightness and saturation, with some modes overbrightening shadow and midtone content.

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

LG’s desktop software makes adjusting settings easier than using the monitor controls, despite a brief loading delay.

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

The two-year panel warranty feels short beside common three-year OLED coverage, with burn-in terms not always clearly promoted.

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

The OLED picture quality is top-tier, but its premium price and cheaper competitors make the value proposition hard to defend.

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

HDMI 2.1 connectivity suits modern consoles and PCs and supports high-resolution, high-refresh video feeds.

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

Materials and construction are generally solid, although the large display can move on its stand when nudged.

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

A restrained chassis, slim bezels, and understated stand give the large OLED a clean, polished appearance.

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 warmer Reader mode and hardware low-blue-light provisions make lengthy text sessions more comfortable.

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

The 39-inch format gives noticeably more vertical presence than 34-inch ultrawides without the imposing dimensions of a 45-inch panel.

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

Gamma is reasonably controllable, but several factory and HDR settings shift dark or midtone brightness away from the intended target.

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

The reduced esports-size window works, but the small active area and coarse lower-resolution image are awkward on such a large panel.

Automatic picture adjustment may suit hands-off users, but it can upset creators who need stable color and brightness settings.

The 21:9 format expands game views and workspace substantially; standard 16:9 inputs need side borders rather than full-screen stretching.

A dedicated black-frame-insertion mode is missing, leaving a gap for gamers who want further sample-and-hold blur reduction.

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

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

The gentler 1500R curve draws in the edges for immersive play without the distortion and discomfort associated with LG’s earlier 800R curves.

Despite its large 39-inch screen, the monitor occupies less width than many dual-screen arrangements or 45-inch ultrawides, but a deep desk helps.

Switching between highly detailed 165Hz output and much faster 330Hz action adds flexibility, but the lower-resolution mode looks visibly soft.

LG’s companion software adds access to firmware updating and useful display controls.

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

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

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.

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

The monitor worked reliably with a Mac, including dual-mode, making it practical as part of a mixed Mac/PC desk.

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

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

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 best HDR and SDR looks can require separate picture presets, creating extra switching work for mixed media use.

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

Audio is serviceable at ordinary volumes but lacks bass and can turn thin with demanding music or movie soundtracks.

The 21:9 curved screen supplies a wide field of view and deep immersion, especially in games that natively support ultrawide layouts.

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

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

AI audio enhancement receives mixed-to-negative reactions: voices may become clearer, but compression artifacts and compatibility limits reduce its usefulness.

The internal cooling fan is nearly inaudible in normal use, with noise noticeable only at extremely close range.

Displaying two inputs at once helps multi-device use, though refresh rate can drop when sharing the panel between a Mac and PC.

Standard 16:9 console or video sources can display correctly with black sidebars instead of stretched proportions.

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

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

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

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

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