Compare LG 27GR83Q-B vs Samsung Odyssey 3D G90XF S27FG900X

A light matte finish suppresses reflections effectively without making the picture overly grainy.

The glossy lens surface can produce sharp-looking color but readily reflects windows and overhead lights. Reflections become particularly frustrating during daytime gaming or when concentrating on the stereo effect.

Story-driven games can still look good in SDR, but dark-scene contrast and weak HDR blunt their cinematic impact.

Immersive open-world games benefit from detailed 4K visuals and smooth motion. Supported 3D titles can add striking depth, especially when the player is free to slow down and enjoy the scenery.

PS5 and Xbox owners benefit from strong HDMI compatibility, 120Hz support, VRR, and useful 4K-input downscaling. HDR quality remains the main console caveat.

Consoles can use the screen as a capable conventional 4K display, but the Windows-based 3D features do not translate to Xbox or PlayStation. The 3D premium therefore goes largely unused in console-focused setups.

The FPS and RTS presets are seen as gimmicky by one owner, who prefers choosing settings manually.

Genre-oriented modes provide bright, colorful starting points, and an accurate default is usable without extensive tweaking. Differences between presets are modest rather than transformative.

1440p is easier to drive than 4K, but approaching 240fps in demanding games still calls for a capable graphics processor and CPU.

Smooth 3D places heavy demands on the connected PC, often calling for high-end Nvidia graphics and substantial system memory. Less powerful or differently configured machines face restricted features or big frame-rate losses.

The IPS panel holds its image well from the sides, making shared viewing more comfortable than on many VA competitors.

The IPS panel is usable head-on but can lose brightness or shift color as the viewer moves off-axis. Stereo viewing is even more dependent on staying within the tracking range.

The V-shaped stand can take more desk depth than compact alternatives, although one tester finds the legs less intrusive than expected.

The relatively flat base and 27-inch format fit standard desks better than the price and novelty might suggest. There is still a solid stand beneath the panel, but it need not overwhelm the workspace.

There are no internal speakers, so a headset or separate audio setup is needed for sound.

The speakers sound clear and reasonably loud for casual viewing, sometimes outperforming ordinary monitor audio. Their limited bass and less convincing directional effects leave room for external sound systems.

A dependable, fast 1440p gaming monitor that earns broad approval for responsive play. The limited HDR image and changing sale prices are its recurring qualifications.

The extraordinary 3D effect makes a compelling technology showcase, while the cost and compatibility issues leave the overall purchase divisive. It is easier to admire than to recommend broadly.

Two HDMI 2.1 connections, DisplayPort, USB-A, and audio output cover gaming essentials well, but the missing USB-C dock-style input restricts work use.

Dual HDMI connections, DisplayPort, and USB provide a workable gaming setup, but the lack of USB-C and DisplayPort 2.1 feels stingy at this price. Some layouts are more accessible than others.

Standard 100×100mm mounting and a positive firsthand arm-mounting account make it straightforward to free up desk space.

Standard mounting support offers an alternative to the included stand. A wall mount or monitor arm can help personalize a desk or clear more working space.

240Hz, low latency, and good motion tuning are particularly persuasive for esports and fast shooters. Running close to 240fps makes the most of it.

Smooth 165 Hz 2D play and quick responses work well for most fast games. Serious esports players can find even faster, more responsive alternatives, and the 3D mode is a poor fit for maximum frame rates.

Controls feel immediate, and measured processing delay is consistently very low. That makes fast reactions one of the monitor's most convincing strengths.

Input lag can feel practically imperceptible in regular gaming, and some measurements are comfortable for casual play. Serious competitors may want the lower latency available from esports-focused alternatives.

The standard base feels secure despite its broad legs, with testers generally describing sound construction.

The wide, substantial stand generally holds the panel firmly with little wobble. Its reassuring weight contributes to the premium feel.

Wide-gamut coverage brings vivid color, with sRGB limiting available when accuracy matters more than saturation.

Colors generally look saturated and appealing, with strong sRGB coverage and useful wide-gamut output. OLED alternatives can still look more vivid, and some testing found limited coverage in certain presets.

Its 240Hz operation is a major draw, noticeably smoothing fast games compared with 144Hz or 165Hz displays when the PC can supply enough frames.

At 165 Hz, conventional games feel fluid and responsive. The number is respectable but no longer leading-edge for an expensive gaming monitor, and 3D mode has its own limits.

Fast generally works best at medium and high refresh rates, while Normal is preferable around 60Hz; the most aggressive setting sacrifices visual cleanliness.

The factory Faster setting is a sensible compromise between sharp movement and artifacts. Pushing to Extreme cleans up some blur but creates obvious trails behind moving objects.

The matte coating helps in brighter surroundings while leaving the image reasonably clean and clear.

The glossy front can make color look rich and avoid a grainy anti-glare texture. Its optical layer may show a faint grid or other artifacts at close range.

Games and text look crisp at the 27-inch QHD pixel density, making the step up from 1080p worthwhile.

Standard 4K content can look crisp and highly detailed, especially in games and productivity tasks. The lenticular coating and softer edges sometimes undermine that advantage compared with normal 4K monitors.

Rear connections are easy to find but not always convenient for frequently unplugged accessories, resulting in mixed assessments.

The rear ports are reachable when facing the screen, although their orientation can make it easier to turn the monitor around when plugging in cables.

Blacks are relatively shallow compared with VA, mini-LED, and OLED displays; dim scenes may look gray rather than deep black.

The IPS panel offers acceptable blacks in ordinary lighting but falls short of OLED depth in a dark room. Some find them decent for LCD, while others notice gray-looking dark scenes.

Height, tilt, and portrait pivot are useful, but swivel is absent; one assessment describes broader adjustments, so physical flexibility is not completely agreed upon.

Height, tilt, and portrait rotation offer practical ways to position the screen. Multiple assessments call the range generous, though swivel flexibility is disputed or absent in more detailed testing.

The pixel density is noticeably finer than a comparably sized 1080p monitor, improving text and small in-game details.

Packing 4K into a 27-inch panel makes individual pixels hard to distinguish in normal 2D viewing. The fine density also helps counter the apparent resolution loss from its 3D optical layer.

FreeSync and G-SYNC compatibility work well across differing frame rates, giving gamers tear-free play without major reported disruptions.

Variable refresh support helps keep ordinary games tear-free across capable PCs and consoles. That smoothness is separate from the restricted glasses-free 3D mode.

Crosshairs, a frame-rate counter, and black stabilizer cover the common gaming extras, though the selection is not especially expansive.

The gaming menus offer useful options such as targeting aids, picture modes, input choice, and display tweaks. The selection covers ordinary gaming needs alongside the specialty 3D controls.

1440p is a satisfying middle ground between crisp detail and attainable high frame rates, especially on a 27-inch screen.

The 4K panel supplies finely detailed imagery for games and ordinary desktop work. The impressive native resolution does not mean each eye sees the full 4K image in stereo mode.

Pixel transitions generally keep pace well with fast play, although technical tests find the claimed 1ms figure optimistic and tuning less ideal at the refresh-rate extremes.

Rapid pixel response keeps conventional movement snappy and reduces visible blur. It performs well for an IPS panel even though leading OLED alternatives can transition faster.

Two USB-A downstream ports serve simple peripherals, but the upstream connection is USB-B and there is no convenient USB-C docking solution.

A USB upstream connection activates additional ports and the tracking hardware. It is a practical convenience, even if a dedicated USB-C laptop connection is absent.

Fast-moving objects remain clear and fluid at high refresh rates, with a few testers noting OLED or premium strobed LCD alternatives can look sharper.

Standard 2D motion is often described as quick and fluid, especially with adaptive sync and a sensible overdrive setting. OLED alternatives provide cleaner fast motion at the premium end.

With sRGB adjustments or calibration, colors can become accurate enough for serious photo work even though it is primarily a gaming screen.

Factory-tuned color and 4K detail make occasional photo edits comfortable and precise. It can work as a creative display even if its unusual 3D layer is unnecessary for most editing.

The Fast overdrive mode contains inverse ghosting well, but maximum settings can introduce visible overshoot.

Motion stays comparatively crisp at sensible overdrive settings, with little blur in demanding test scenes. An extreme overdrive level can create distracting trailing artifacts.

Sturdy materials and restrained styling make the screen feel better finished than its utilitarian feature set might suggest.

The metallic silver styling and substantial stand give the monitor an upscale character. The design feels more finished than the experimental nature of the underlying 3D technology might suggest.

Uniformity is reasonable rather than exceptional, with some edge falloff that may vary from unit to unit.

Edge darkening and minor blur can draw attention during web browsing or documents, although other testing found good white-field consistency. The effect is less obvious during games.

HDR color and tone presentation need work, even apart from the more fundamental missing local dimming.

In ordinary HDR gaming, tone mapping can render colors and scene brightness convincingly. Dynamic mapping is a useful option for getting more from HDR10 material.

The value rises sharply when discounted into the roughly $300–$400 range. Several testers consider its original $500 positioning hard to justify against newer, less expensive rivals.

Glasses-free 3D is exciting, but the high asking price is hard to defend for most shoppers given its narrow compatible catalog. A minority find the uniqueness worth paying for as dedicated early adopters.

DisplayPort offers a reliable route to high-refresh QHD PC play alongside the two well-equipped HDMI inputs.

DisplayPort 1.4 works for conventional connectivity, but the lack of the newer 2.1 standard disappoints at this price. Some would expect more forward-looking ports on such an expensive display.

A quick joystick and responsive menus make changing picture modes, overdrive, and inputs relatively painless.

The joystick-driven menu offers useful controls and generally navigable options, though some adjustments require too many clicks. Software-based controls can make repeated changes easier.

With no meaningful local-dimming system, bright objects cannot pop against deep blacks the way they can on mini-LED or OLED screens.

The edge-lit approach relies on basic whole-frame dimming rather than precise zones. It can boost overall contrast, but it does not reliably protect highlights and may introduce distracting tonal changes.

SDR picture quality is attractive and sharp for the price, especially in bright games, with the expected IPS limitations in dark material.

Its sharp, bright 4K IPS image is enjoyable in many settings, but the lens layer and basic dimming can impair clarity or contrast. Picture quality alone is not the reason to pay the 3D premium.

DTS Headphone:X can enhance positional sound and movie immersion when used with compatible headphones.

Directional audio adds some presence to 3D scenes but does not convincingly replace strong external speakers or headphones. The perceived surround effect varies considerably across comparisons.

HDR input is supported, but the display lacks the contrast and local dimming needed for convincing bright highlights against dark scenes.

HDR color can be enjoyable, but bright highlights and black depth lack the punch expected from similarly priced OLED or mini-LED monitors. HDR also cannot be enjoyed simultaneously with the proprietary 3D effect.

Bright SDR output is a real asset in sunny rooms, although the impressive headline luminance cannot compensate for weak HDR contrast.

Day-to-day SDR brightness can be plentiful, with some strong measured peaks. Other testing found more ordinary output, and the panel does not deliver the dazzling HDR highlights of stronger alternatives.

Colors are often good to very good after modest adjustments, while factory oversaturation and differing white points prevent universal out-of-box precision.

Factory tuning is frequently a highlight, with natural, accurate color reported without a full calibration process. Some modes fall behind rival gaming monitors, so the chosen picture preset matters.

Contrast is acceptable for an edge-lit IPS panel, yet the limited separation between bright and dark elements is conspicuous in cinematic scenes.

IPS contrast is serviceable, and whole-frame dimming can improve the measured ratio in some scenes. Dark-room depth still trails comparably priced OLED or stronger mini-LED displays.

Variable refresh runs smoothly with both major GPU ecosystems; testers report few flicker or tearing issues.

FreeSync and G-Sync compatibility help conventional gaming stay smooth and tear-free. These benefits apply to standard play, not all of the specialized 3D display modes.

The black stabilizer can lift shadow visibility to make opponents easier to spot, a practical gaming adjustment rather than a cure for poor native contrast.

The dark-area brightening aid can make opponents easier to see in shadowy scenes. It is a practical gaming control alongside the monitor's more experimental 3D options.

Gamma is broadly near target in tested modes, with the adjustable sRGB preset helping achieve better tonal accuracy.

Default gamma can run slightly above the usual target, giving shadows a deeper look. An available adjustment can bring it closer to standard tracking when precision matters.

Thin framing helps the understated look, though another tester finds the bezels slightly larger than on some other LG 27-inch displays.

The tracking cameras require an enlarged upper bezel, but they are discreetly incorporated into the frame. The finished monitor still looks reasonably streamlined from the front.

Muted gray styling looks tidy on a desk and avoids aggressive lighting; the industrial rear housing is still distinctly gaming-oriented.

The silver chassis, flat stand, and relatively restrained styling look modern and premium. The extra tracking hardware is incorporated neatly enough that the screen largely resembles a normal gaming monitor.

Construction receives positive comments for solid plastics and a stable-feeling build, rather than flashy materials.

The sturdy stand and clean housing create a substantial, polished impression. Even the less elaborate plastic parts generally feel well assembled rather than experimental.

Flicker-free backlight operation is a welcome characteristic for people who notice screen flicker.

Brightness control avoids PWM flickering in the reported test, which is welcome for sensitive eyes. This does not eliminate the possibility of visual discomfort from the separate stereo 3D effect.

The 27-inch panel offers a comfortable desktop footprint and room for several windows, without matching the canvas of a larger editing display.

The 27-inch diagonal is a comfortable middle ground for desktop gaming. It is large enough to appreciate 3D depth without requiring the space of a much bigger display.

Side-by-side stereoscopic video is supported and can look impressive, but native frame-sequential 3D Blu-ray playback is missing. This is a meaningful distinction for anyone with a traditional 3D movie collection.

The supported game selection is the monitor's biggest stumbling block. It can make compatible titles spectacular, but the roster has been small and inconsistent enough to make the premium difficult to justify.

Depth and pop-out controls let players tailor the dimensional effect, while remappable shortcuts make adjustments less disruptive. The custom controls are especially welcome when a default shortcut conflicts with game inputs.

Three-dimensional play involves substantial display compromises: HDR and adaptive sync cannot be combined with the effect in the described setups, while 3D refresh or effective resolution may be lower than in 2D.

Stereo rendering divides image information between the eyes, producing some softness, grain, or fringing. The effect nevertheless looks strikingly detailed and natural in its best optimized games.

Tracking permits some head movement without losing the stereo illusion. Sitting too far to the side, moving rapidly, or leaving the viewing range can still compromise the image.

The automatic converter can make compatible videos feel layered and surprisingly immersive. Dark scenes, protected streams, unsupported content, and depth-map artifacts keep it from matching games designed for 3D.

The absence of strobing is a disappointment for gamers wanting the sharpest possible moving images at 240Hz.

The speakers handle basic audio but lack low-end impact. Explosions, music, and cinematic effects benefit from external speakers or headphones.

The lower light strip adds a restrained splash of color and can follow the image on screen. Its front-facing position makes the effect more visible than typical rear-facing monitor RGB.

Rear-facing and outward-facing connections offer mixed convenience, but the stand's cable opening helps keep the desk orderly. The stand opening is not especially large, so several cables may need extra arranging.

The default image can be accurate enough that calibration is unnecessary. Small gamma or color tweaks are available for anyone who wants to fine-tune further.

Copy-protected streaming is a major barrier to automatic 3D video conversion. Netflix and other protected movies may stay in 2D or produce a blank screen rather than the promised dimensional effect.

Lifelike depth without wearing glasses is the standout accomplishment, producing memorable foreground effects and convincing environments. Alignment hiccups, limited content, and occasional artifacts prevent it from feeling completely mature.

Some HDR content benefits from the supported color depth, which can make transitions look smoother than SDR.

Limited highlight headroom can clip bright information and reduce separation in high-contrast scenes.

Availability of a wired headphone jack is uncertain across the described configurations: some found one, while others could not. Check the exact regional model if a direct headphone connection matters.

Its headphone connection supports DTS Headphone:X and can be useful with compatible headsets; the enhanced spatial experience depends on the headphones.

Accepting a 4K/120Hz console signal and scaling it to QHD is an appreciated compatibility convenience.

The IPS panel gives pleasing speed, bright SDR output, and broad viewing angles, at the cost of OLED-like blacks and contrast.

This is a strong fit for modern PC gaming, especially fast titles with capable graphics hardware and DisplayPort or HDMI 2.1 output.

The 27-inch size and manageable weight make repositioning it easier than moving a larger display. It still feels solid once placed on its desk stand.

Measured power use is low for a bright 240Hz IPS screen, minimizing the monitor's energy penalty.

Fast gaming is clearly its priority; office-oriented rivals can offer more convenient connectivity and switching options.

A PlayStation can be connected for standard display use, but its games cannot use the Windows-based glasses-free 3D conversion. That makes the costly headline feature unhelpful to a PS5-only setup.

Testing reports clean VRR behavior without noticeable flicker, including with adaptive sync engaged.

Head and eye tracking generally keeps the stereo picture anchored as the viewer shifts position. Fast movements can cause a brief loss of alignment, and the system is designed around a single primary viewer.

Supported games can look terrific, but their 3D effects are not uniformly stable. Certain cutscenes, scanning failures, doubled images, and occasional artifacts can break immersion.

Full-bandwidth HDMI 2.1 inputs are a standout at this price, providing high-refresh compatibility beyond what many rival 1440p monitors offer.

The stand attaches without fuss, and the basic monitor is straightforward to assemble. Enabling glasses-free 3D requires the companion application and additional USB and display configuration.

The extra rendering work can severely cut frame rates, especially in unsupported or demanding titles. Powerful test systems sometimes handled the effect smoothly, but that is far from guaranteed.

Fast menu response and reliable PC-to-console input changes are strengths, aided by configuration options for sleep behavior.

The advertised 1ms pixel response should not be taken literally in normal operation, though most other stated specifications hold up.

Avoiding a headset or glasses makes extended 3D sessions feel surprisingly natural for many viewers. Others encounter disorientation, eye strain, or distraction, so individual tolerance matters.

Flicker-free backlighting and a low-blue-light setting provide basic comfort controls.

An adjustable sRGB mode, unlocked RGB controls, and hardware calibration support are unusually useful for a midrange gaming display.

The companion display-control utility makes changing the monitor's regular settings more convenient than working through the rear joystick. It is a helpful option for a desktop setup.

The launcher can discover compatible games and manage depth settings, but its stability and usability vary sharply. Missing titles, disruptive visuals, extra setup steps, and a small catalog make the software feel unfinished to some users.
