Compare Samsung Odyssey OLED G80SH S32HG802S vs Dell Alienware AW2725DM

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

HDR bright objects can develop distracting halos, making the limited local-dimming system a major weakness.

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 charging is absent, frustrating users who want to power a laptop or small device directly through a modern USB-C port.

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

Highlights are sometimes mildly brighter than in SDR, but small bright details can look muted and haloed.

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.

The IPS panel cannot match the deep blacks of stronger VA, Mini-LED or OLED alternatives.

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

Basic motion is clean, but VRR can add blur and the most aggressive overdrive may produce bright inverse trails.

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 missing 3.5mm output complicates console or external-audio arrangements that rely on the monitor as an audio source.

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

The missing glowing Alienware emblem disappoints buyers who wanted the brand’s signature RGB appearance.

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.

Useful HDMI, DisplayPort and USB-A connections cover basic PC gaming, but absent USB-C and audio ports narrow its flexibility.

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

Some hands-on testing found dark scenes detailed and convincing from an angle, despite other complaints about overall black depth.

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

The stand is repeatedly praised as solid and secure, including when adjusted on smaller desks.

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

Sample-to-sample consistency is a concern: one review praised nearly uniform lighting, but a buyer needed a replacement for severe corner glow.

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

The anti-glare surface helps in ordinary light, but some testing still found distracting reflections near bright windows.

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

Fast IPS keeps costs down and offers useful viewing angles, but sacrifices OLED-like blacks and HDR impact.

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

Indigo styling and smooth curves look premium to several owners, though budget plastics make the finish less convincing to others.

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-gamut colors make games vivid, though unmanaged sRGB content may become oversaturated.

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

Included video, USB and power cabling makes the monitor easier to set up without extra purchases.

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

There are no speakers. Some welcome avoiding weak budget audio, while others find the omission inconvenient for console or video playback.

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.

180Hz motion and quick response make shooters a strong fit, though VRR blur and faster 320Hz alternatives temper top-tier esports appeal.

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

Menus and overlays offer plenty of useful game settings, although another assessment sees the extras as relatively basic.

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

QHD delivers better detail than 1080p with less strain than 4K, but older GPUs may struggle to sustain 180 fps.

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 at 1440p and up to 120Hz, but full 4K/120Hz bandwidth and some audio passthrough features are unavailable.

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

Colorful AAA games still look appealing, although lackluster HDR and shallow blacks stop it from being a cinematic showcase.

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

Support for NVIDIA G-SYNC, AMD FreeSync and common adaptive-sync standards makes the monitor flexible across gaming PCs.

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

A stand cut-out tidies cables effectively, although front-bottom USB placement can expose wires and not everyone loves the routing.

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

QHD at up to 180Hz is an appealing PC gaming balance; use DisplayPort for the full refresh capability.

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

Fast pixel response gives competitive games pleasing clarity, with overdrive settings still requiring sensible tuning.

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

Most hands-on tests praise fluid 180Hz motion and quick transitions, although VRR can make moving objects look blurrier.

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

Clear text, textures and fine game objects are repeatedly praised over older 1080p setups.

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

Low measured input lag supports responsive play in fast games.

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

FPS, sports and customized game profiles give players quick ways to tailor visibility and color; sports mode particularly impressed one owner.

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

At roughly 108–109 ppi, text and game textures look crisp without forcing the heavier processing requirements of 4K.

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 2560×1440 resolution is repeatedly praised for sharper graphics and text than 1080p, while remaining practical for gaming hardware.

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

Its IPS image stays consistent off-axis and is favored for side viewing and shared-screen play.

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

Height, tilt, swivel and pivot adjustments earn some of the strongest and most consistent praise across the reviews.

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 USB-A ports handle basic accessories or device charging; their usefulness is undercut by varying opinions about placement.

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 180Hz refresh rate makes gameplay visibly smoother than 60Hz and is a central draw for this value-focused monitor.

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.

Overall impressions favor this as an affordable, well-rounded gaming screen, with purchase enthusiasm depending on discount pricing and HDR expectations.

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.

It can accept a 4K/60Hz console feed and display it on the native QHD panel, which adds flexibility but not true 4K resolution.

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

VESA mounting offers an alternative to the included stand, and attachment was described as straightforward.

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

A second connected source was detected automatically and prompted a convenient switch in one hands-on test.

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.

HDR is the recurring compromise: limited IPS contrast, modest brightness and awkward local dimming outweigh occasional praise for vibrant color.

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

The typical IPS contrast limits dark-scene depth and HDR. One owner nevertheless saw an improvement over a much older TN screen.

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

Variable refresh avoids tearing and works seamlessly for some, but testing also found extra blur when VRR was turned on.

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.

Its approximately 400-nit brightness is usable and sometimes praised, but does not create standout HDR impact or lead in bright rooms.

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.

QHD sharpness and vibrant SDR colors impress, while black depth and HDR contrast lag behind stronger display technologies.

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 is the preferred route to full 1440p at 180Hz; one reviewer wishes the port were a newer version.

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

Rich, bright colors make visually driven games attractive in normal use.

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

Several owners love the color presentation, but factory white-balance concerns and recommended ICC calibration make precision accuracy less certain.

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-driven menus are consistently praised for clear navigation and easy access to common settings.

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, which limits convenience for shared keyboard-and-mouse setups across multiple computers.

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

The HDMI 2.1 naming does not bring full FRL bandwidth: QHD tops out at 144Hz over HDMI, with DisplayPort required for 180Hz.

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

Repeatedly recommended at sale prices around $190–$220, it offers unusually attractive gaming specs; value weakens as the price rises.

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

Tool-free stand assembly and straightforward controls make getting started unusually simple.

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

Thin top and side borders help the monitor look clean and contemporary.

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

The distinctive indigo curves and sleek bezels win frequent compliments, but some prefer black or miss the illuminated Alienware logo.

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

The 27-inch size is widely seen as a good match for QHD and feels like a meaningful improvement over smaller older panels.

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

Most hands-on opinions praise sturdy construction and an ergonomic stand; one found the plastics a little generic.

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 warm preset reduces harsh blue tones and was described as easier on the eyes.

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

Custom game profiles and adjustable color values help players keep preferred looks without readjusting every session.

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

HDR operation locks out some brightness, preset and Dark Stabilizer controls, limiting customization.

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

Backlight bleed varies strikingly by unit: one tester saw almost none, while an owner replaced a unit with severe corner glow.

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

A Dell ICC profile and available color controls provide a useful starting point, although best accuracy may require calibration.

Broad color support contributes to an appealing, vivid picture, especially alongside the monitor’s wide-gamut IPS panel.

Its modest stand base saves valuable desk surface without sacrificing major adjustments.

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

Eco-oriented protective packaging received a favorable mention during unboxing.

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

The power supply being housed inside the screen is appreciated for simplifying the desk setup.

A Mac Studio user found it an excellent additional display, especially with adjustable height for matching nearby screens.

Extreme mode worked particularly well for one tester, but another cautions that aggressive settings can cause overshoot at fluctuating frame rates.

One unboxing praised the monitor for being exceptionally well packed.

An owner reported severe corner IPS glow on an initial unit and a dramatically cleaner replacement, highlighting inconsistent samples.

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.

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

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

PS5 testing shows enjoyable 1440p/120Hz support and 4K/60Hz signal acceptance, but not true 4K/120Hz output.

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.

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

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

Some owners love reaching ports from underneath the front edge; others find the ports awkward or dislike visible dangling cables.

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

Selectable crosshairs and visibility aids add handy targeting options, especially for games such as Fortnite.

Without eARC, connecting a soundbar through the monitor is not a practical option for some console setups.

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

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

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 local-dimming implementation produces distracting halos and cannot be switched off in HDR, making it one of the clearest drawbacks.

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.

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.

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

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