Compare LG 27GM950B-B vs Dell Alienware AW2725DF

Tiny text, high-resolution photos and game details look especially crisp at native 5K. QHD dual mode is softer and is best reserved for gaming rather than desktop work.

The default sharpening can exaggerate edges or make tiny details look spotty; lowering it produces a more natural picture for some users.

Its semi-matte surface reduces distracting room reflections without severe blur for most users. Glossy-screen fans may still notice a slightly grainy finish.

The glossy coating creates a clean, vivid image but reflects windows and lamps; raised purple blacks are particularly noticeable under direct ambient light.

PlayStation testing confirms 4K/120Hz video with HDR and VRR, while lower-resolution console sources can benefit from optional upscaling.

Consoles can use 1440p at 120Hz, but limited HDMI bandwidth restricts higher-bandwidth modes and complicates the ideal 4K HDR/120Hz combination.

Up to 90W charging makes it convenient to run most compatible laptops from the monitor. Very power-hungry machines may still need a separate power adapter.

The USB-C accessory port can charge small devices at limited wattage, but it does not offer meaningful laptop power delivery or carry video.

The external snap-on cable clip is a weak point: it feels inexpensive, has limited capacity, and can leave a USB-C cable hanging near the controls.

The stand's routing channel and rear cover are useful for hiding wires, although recessed video ports can be awkward to reach when swapping devices.

The backlight produces powerful larger highlights while preserving dark blacks. Very small bright objects such as stars and lamps can be dimmed too heavily or disappear.

Specular HDR details look vivid and sharply separated from black backgrounds, though the high peak is restricted to very small bright areas.

Two downstream USB-A ports are useful for basic accessories but form a limited hub. More demanding multi-device desks benefit from a proper docking station.

A useful downstream USB-A and USB-C arrangement keeps mouse and keyboard peripherals handy, though it does not turn the monitor into a USB-C laptop dock.

On-display AI upscaling can sharpen a lower-resolution console or video feed. Gains on PCs are smaller and sometimes hard to activate, where native game upscalers tend to be better.

Downscaled virtual-4K modes can help some HDMI devices, but the resulting 1440p image and restricted output modes limit their usefulness.

DisplayPort 2.1, two HDMI 2.1 inputs and USB-C provide excellent modern video connectivity. Missing KVM and more extensive USB docking are the notable limitations.

Two DisplayPorts and convenient USB accessory ports are useful, but limited HDMI bandwidth, no USB-C video input and the lack of audio output make connectivity feel incomplete.

One tester encountered unusually long blank screens when connecting a GPU, while a deep-sleep option deliberately wakes more slowly to save energy.

A small number of experiences describe serious picture-loss or maintenance-cycle problems that interrupt use, despite otherwise positive day-to-day operation.

The Mini LED panel avoids the characteristic permanent image retention risk of OLED technology, an appealing consideration for desktop-heavy use.

Pixel and panel refresh routines help manage OLED wear, backed by a three-year burn-in warranty. The relatively limited user-adjustable safeguards and persistent static-content risk remain drawbacks.

USB firmware updates are supported and can correct an early sharpness defect. The process may be slow or frustrating when the LG utility fails to recognize the screen.

Firmware can be updated through Dell's tools, and an update apparently resolved one instance of intermittent gray-screen failures. The update process adds another setup step.

The box includes HDMI, DisplayPort and USB-C cables alongside the power supply and stand, reducing the need for immediate extra purchases.

The supplied stand, signal cables and accessories make setup convenient, although the missing HDMI cable in some kits is criticized.

The matte anti-glare layer generally retains impressive detail without the severe haze of some competitors. A few users dislike its subtle grain and shimmer versus glossy glass.

The semi-glossy QD-OLED finish looks clearer and less grainy than many matte OLED coatings, with extra reflections as the tradeoff.

Conventional RGB subpixels and high density make letters unusually clean, with little distracting color fringing for most users. The matte coating draws a few complaints.

Third-generation QD-OLED reduces the colored edges seen around small text, but fringing and lower text crispness remain noticeable to sensitive users.

At 27 inches, native 5K makes desktop text and high-resolution photos visibly sharper than 4K. The benefit is less dramatic in many 3D games and comes with a substantial graphics-performance cost.

1440p is a useful sweet spot for detailed gaming at very high frame rates, but fine desktop text and modern 4K content cannot match the crispness of true 4K screens.

Pixel transitions are sound for a modern IPS panel, especially with suitable overdrive. They remain slower than OLEDs and do not fully keep pace with the 330Hz ceiling.

Near-instant OLED pixel transitions keep fast objects clean and responsive without the usual LCD overshoot or trailing.

Native 5K detail and vivid HDR can flatter richly rendered campaigns. Some dark scenes are over-dimmed, making OLED alternatives more dependable for cinematic HDR perfectionists.

Atmospheric, narrative-driven games benefit enormously from saturated color, precise highlights and black scenes, even when they do not approach 360fps.

Assembly is straightforward, although the crumbly Styrofoam packaging feels less polished than the premium price suggests.

The packaging usually protects the panel well, although at least one unboxing showed conspicuous box damage.

Power draw is relatively high for a 27-inch LCD, especially during bright gaming. A deep-sleep option can reduce standby consumption at the cost of slower wake-up.

Higher power draw than expected, including unusual standby use in one test, weakens the efficiency case compared with some conventional screens.

Most tests praise exceptionally restrained halos for an IPS Mini LED display. One owner still found obvious bloom around a cursor, while the aggressive dimming can suppress tiny lights.

Bright objects sit against black without the blooming or halos of zone-lit LCDs, making night scenes especially striking.

Integrated speakers are acceptable for everyday sounds and simple gaming. They are thin or metallic sounding in voices and do not replace proper speakers.

The lack of speakers leaves console and streaming-device users arranging external audio, which can make otherwise straightforward hookups less convenient.

The appearance and image controls can feel distinctly high-end, although plain plastic surfaces and software rough edges undercut that impression for some.

The clean styling and polished thin panel give a premium first impression, though plastic construction tempers the luxury feel.

Powerful Windows PCs can use the full native 5K/165Hz mode and high-speed QHD option. High GPU demands and some firmware quirks complicate an otherwise versatile setup.

Connected over DisplayPort, this is an outstanding PC gaming display with remarkably clean motion and low lag. Gamers need a capable PC and the right connection to make the most of 360Hz.

The high-density, dual-refresh design makes a strong impression, but owners disagree about whether its HDR quirks and high price undermine the purchase.

Overall satisfaction is very high among gamers enjoying the OLED upgrade, with some caveats around cost, reliability and panel upkeep.

Normal fast-overdrive settings keep inverse trails low, making motion respectable for an IPS panel. More aggressive tuning can introduce overshoot.

Fast-moving objects show very little ghosting or overshoot, keeping rapid camera pans unusually clean at high refresh rates.

Action is smooth and sharp by LCD standards, especially in 330Hz mode. A little trailing blur remains, so top OLEDs are still clearer.

The 360Hz QD-OLED panel keeps fine moving details visible and cuts blur noticeably compared with lower-refresh displays. The gain over 240Hz is real but subtler than larger refresh-rate jumps.

The 1440p/330Hz mode and low latency work well for shooters and racing. OLED competitors retain an edge in response speed, and overdrive tuning is less consistent across refresh rates.

Exceptional clarity, low lag and up to 360Hz make this a particularly strong competitive PC gaming screen when the system can deliver high frame rates.

Text clarity and high resolution suit office and creative tasks, but the smaller physical screen and missing advanced docking features hold it back as an all-purpose workstation.

The display can handle occasional desktop tasks, but OLED wear concerns and text rendering prevent it from being the most comfortable all-day work monitor.

Changing HDR mode preserves the color presentation on tested Mac systems, making everyday switching more convenient.

Well-managed SDR content in HDR mode can reduce the need for constant switching between display modes, provided its brightness tradeoffs are acceptable.

VESA mounting lets buyers replace the stock stand with an arm without sacrificing a pivot and height-adjustable stand option at purchase.

Standard 100×100mm VESA support makes it straightforward to swap the supplied stand for a wall mount or monitor arm.

Variable refresh support works across common PC standards and also supports tested 4K/120Hz console gaming, helping prevent tearing.

Variable refresh rate works smoothly across supported modes in many setups, although its benefits diminish when frame rates fluctuate enough to cause flicker.

With local dimming enabled, this IPS display can produce remarkably deep blacks. The unassisted panel's native contrast is much weaker, and small highlights sometimes lose brightness.

Inky, individually controlled blacks are a defining strength for games and movies in controlled lighting. Direct room light can lift the panel to a grayish or purple appearance.

Input response is very quick in SDR, helping fast games feel connected to controller or mouse movements. HDR backlight processing can add some delay.

Very low display lag delivers quick-feeling mouse and controller responses, an advantage in fast competitive titles.

Switching between 165Hz at native 5K and 330Hz at QHD gives players a real speed-versus-detail choice. The top rate requires compatible hardware and the lower resolution.

Native 360Hz refresh is the headline advantage, bringing exceptional speed and refined motion for esports without requiring lower resolution on the panel itself.

Height, tilt, swivel and pivot adjustments allow comfortable landscape or portrait placement without buying a separate monitor arm.

Height, tilt, swivel and pivot adjustments help fit the display to varied positions, and the mounting and movement generally feel straightforward.

Game profiles, black stabilization, frame counters and shortcut customization give players useful control without a sprawling, confusing menu.

Creator and Smart HDR modes offer useful options, but default desktop, movie and game presets can produce blur, excess saturation or uneven brightness depending on content.

Most testers saw excellent or good uniformity, but others noticed darker edges or vignetting on plain white backgrounds.

Brightness uniformity is strong in one measurement but another test found visible corner darkening, making this a modest point of disagreement.

The IPS panel holds color and contrast well from off-center positions, with less obvious haloing than many Mini LED alternatives.

Wide OLED viewing angles maintain color and contrast well when the screen is viewed away from center.

Subtle rear hexagon lighting adds atmosphere without making the front look flashy. Its positioning suits the compact 27-inch frame, and the effects are customizable.

Subtle AlienFX lighting gives the back of the monitor some character, and the colors can be adjusted or disabled. The uneven rear glow does not appeal to everyone.

Native 5K gaming is substantially more demanding than 4K, with sizable frame-rate losses in demanding titles. The 1440p mode is a useful escape hatch for less powerful systems.

Reaching the 360Hz ceiling at 1440p demands a powerful computer or less demanding game settings, so the speed advantage is conditional.

The exceptionally broad gamut produces rich, vivid HDR colors and appeals to photographers. SDR content needs proper gamut control to avoid oversaturation.

A very wide gamut produces rich, saturated colors and notably strong HDR color volume. This is consistently one of the monitor's most admired visual qualities.

The low-profile, flat metal base makes the desk easier to use than a sprawling tripod stand. It leaves space for a keyboard, mouse movement, or small items.

The compact hexagonal foot usually leaves extra desk space for a keyboard and surrounding equipment. Its shape can suit multi-monitor arrangements as well.

The low, flat metal base offers good stability and an unobtrusive shape, with only modest wobble reported during use.

The compact stand is usually firm, but wobble during repositioning and individual ergonomics complaints keep experiences from being unanimous.

Exceptionally tight backlight control makes halos and LCD light spill hard to spot in many dark scenes.

OLED pixels eliminate the conventional LCD backlight bleed that can wash out dark corners, keeping black areas clean.

HDMI 2.1 makes high-resolution console connections straightforward, including tested 4K/120Hz operation on PlayStation hardware.

The HDMI connection is the standout connectivity compromise: despite HDMI 2.1 labeling, its bandwidth is restricted and it cannot carry native 1440p at 360Hz.

Standard country-dependent warranty coverage is available, but at least one tester wishes premium monitors offered substantially longer protection.

Dell's three-year support and explicit burn-in coverage are major reassurances for an OLED purchase, though coverage cannot eliminate the underlying wear risk.

The original premium pricing draws repeated criticism when 4K OLED or Mini LED monitors cost much less. Deep discounts make its unusual 5K flexibility more compelling.

The combined speed and OLED image can justify a premium for dedicated gamers, especially when discounted. Buyers who value size, resolution or connectivity more may see poor value.

Early sharpness defects, intermittent slow wake-ups and occasional corrupted output raise concern despite several strong reports of daily operation.

Long-term confidence is mixed: isolated reports describe freezes, lost pictures and exchanges, while a firmware update resolved one reported gray-screen issue.

The stand snaps together and the display is manageable for one person to unpack. Basic setup is much easier than fixing early firmware issues.

Tool-free stand assembly and straightforward installation make getting started quick, even though rear cable covers can require a little care.

LG Switch offers monitor controls and firmware upgrades, but slow updates, connection detection failures and bloatware worries spoil an otherwise refined interface.

Dell Display Manager and Alienware software offer convenient access to image presets and updates, but occasional control quirks remain.

Tone mapping is a divisive weakness: one test found broadly decent tracking with slightly dark output, while an owner found low- and medium-brightness HDR scenes seriously inaccurate.

HDR mode and preset accuracy are uneven: some preserve highlight detail well, while others darken scenes, crush detail or create excessive saturation.

There are configurable color profiles and LG Calibration Studio support. Professional accuracy benefits from calibration rather than relying solely on the default modes.

Creator presets and custom color adjustments offer useful calibration choices, though there is no hardware calibration and some control options are limited.

The 27-inch size balances high pixel density with a manageable desk footprint. Users wanting a large physical workspace may feel cramped even at 5K.

The jump from a smaller esports display to 27 inches offers more room for work, but can initially feel unfamiliar for highly practiced players.

Reading profiles and subdued bias lighting are welcome conveniences for long desk sessions, though they do not substitute for personal brightness adjustment.

Some find the screen comfortable in dim conditions, but flicker sensitivity and one account of pronounced eye strain make comfort highly individual.

An understated, slim-bezel front, flat metal base and optional rear RGB make for a tidy gaming setup. A few find the gray plastic less premium than expected.

The restrained black-and-gray Alienware styling attracts praise for looking futuristic without becoming gaudy, although some find the housing or bezels overly bulky.

The body feels generally solid and the metal stand inspires confidence, but the largely plastic housing and surface finish do not always feel worthy of the premium price.

The plastic housing is usually regarded as solid and attractive, although a few accounts describe hollow sections, flex or creaking rather than a luxury construction.

One test found that high HDR brightness dropped dramatically after several minutes and did not recover without restarting the display. Another independent tester did not reproduce that behavior, so the experience remains uncertain.

SDR brightness generally stays steady without obvious automatic dimming, while brighter HDR scenes can trigger a noticeable drop in overall luminance. Some testing also raises questions about brightness behavior with particular backgrounds.

Mini LED dimming lifts the IPS panel to impressive real-scene contrast, especially in checkerboard and dark-object tests. Native contrast without dimming remains ordinary.

Pixel-level OLED control creates striking contrast and clean bright-on-black detail in dark environments, although direct light lessens the perceived advantage.

The combination of vivid colors, deep blacks and high peak brightness wins praise in favorable scenes. Owners disagree on consistency: muted dark scenes and reported brightness decay can interfere with immersion.

OLED contrast, color and concentrated highlights make HDR games and films appealing, but sustained bright scenes are less impactful than on strong Mini-LED displays.

Brilliant SDR output and large HDR highlights make daylight use easy. Small highlights are less forceful, and independent tests disagree over whether sustained HDR brightness falls after several minutes.

Small bright details can look dazzling, but full-screen SDR brightness is modest and heavily lit rooms expose its limits. Experiences with actual brightness vary across modes and tests.

A built-in cooling fan is present, but testing found it quiet or effectively inaudible at a normal seating distance.

Cooling-fan noise is generally unobtrusive, but a very quiet environment may make the internal fan faintly audible.

Fine 5K detail, vivid colors and high dynamic range create a striking overall image. Tone-mapping accuracy and consistency are less universally admired.

Vivid colors, deep blacks and highly fluid motion combine into a striking gaming image; modest room-light performance and some mode-specific tuning keep it from being universally ideal.

Despite USB connectivity, there is no built-in KVM switch. Anyone sharing a mouse and keyboard between computers needs another solution.

There is no KVM to share a keyboard and mouse conveniently across computers, despite a useful USB hub and multiple video inputs.

The refreshed on-screen interface is fast, logically arranged and provides handy shortcuts. One tester found the physical joystick small or awkwardly placed.

The joystick-driven OSD is usually intuitive, responsive and easy to navigate, although a few software quirks and limited controls attract criticism.

There are usable sRGB presets and some very good calibrated results. Default SDR saturation or white balance can be inaccurate without color management.

Colors can be remarkably accurate, particularly in Creator sRGB mode, but the default wide-gamut presentation can oversaturate SDR content and the DCI-P3 preset draws mixed assessments.

Full-bandwidth DisplayPort 2.1 can carry high-refresh 5K without display stream compression on compatible hardware, a useful advantage over lower-bandwidth connections.

DisplayPort is the reliable path to native 1440p at 360Hz, making it the preferred connection for high-frame-rate PC gaming.

The quick-access menus, shortcut buttons and preset modes make switching tasks straightforward after setup. Updating firmware can be much less pleasant.

Automatic scene-based changes are available, but dynamic color shifts can undermine accuracy. Leaving the feature off is preferable for faithful image reproduction.

The backlight-strobing mode is unusually clear and retains substantial brightness. It is restricted to native-resolution mode, cannot be used with VRR, and is not ideal for every game.

One arrival had a battered shipping carton but the monitor itself was undamaged, so the reported delivery result was ultimately reassuring.

Mac and Windows users report straightforward connections and sensible scaling. Whether maximum refresh rates are available depends on the connected computer.

The switch between sharp 5K/165Hz and faster QHD/330Hz is a standout strength. QHD sacrifices fine detail but is much more usable than the 1080p alternate modes on some 4K screens.

Crosshairs, frame-rate indicators, AlienVision and shadow tools cover useful gaming extras, though the broader feature set feels lean relative to some premium rivals.

One long-term owner found unusually clean gradients and natural transitions, contributing to an impressively polished image.

The display uses active cooling but has not shown worrying external heat levels in hands-on checks.

This model lacks the streamlined display daisy-chaining available on some higher-end productivity monitors.

A single fast setting works well at native 165Hz. The QHD/330Hz mode needs different overdrive choices across the refresh range, with some overshoot at lower speeds.

This third-generation QD-OLED implementation wins praise for its combination of color volume, contrast and rapid response.

Colorful, accurate Creator presets make the panel enjoyable for photo edits, with attention needed to SDR calibration and prolonged static screens.

Sound is a little better than some monitor speakers and works for everyday alerts, but voices can sound thin and dedicated speakers are better for media.

The USB-C connection is convenient, but the absence of Thunderbolt limits advanced docking compared with some productivity-focused rivals.

Variable-frame-rate gaming can produce visible flicker, most noticeable during darker scenes or erratic performance; a stable frame rate helps.

FreeSync and G-SYNC-compatible variable refresh keep gameplay responsive with little tearing. The best overdrive setting differs by refresh rate in the faster mode.

The simulated audio processing can make dialogue easier to separate from background effects. Other testers would still use a dedicated headset for convincing game sound.

Bass enhancement and AI sound adjustments can make dialogue clearer, but they do not turn the thin built-in speakers into a convincing audio system.

Dark Stabilizer and the shadow-enhancement options can expose opponents or details in dim game areas without dramatically lifting all the blacks.

The glossy glass can show smears and small spots easily, so regular cleaning may take more effort than on a typical matte LCD.

The dense Mini LED backlight brings powerful contrast and controlled bloom. Its conservative tuning can obscure tiny light sources, and not all testers observed stable sustained brightness.

Neither picture-in-picture nor picture-by-picture is available, limiting simultaneous use of multiple video sources.

Gamma looks reasonably close to target in several modes, but some preset tracking and fine-adjustment limits prevent consistent precision.

The glass finish is surprisingly easy to mark or smear and needs careful handling to maintain its clean appearance.

The LG Switch application has failed to recognize connected monitors during necessary updates, making maintenance needlessly frustrating.
