Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: warranty and support service and value for money versus HDR adjustment controls and built-in speakers. Choose according to which strengths matter more to you; the overall score alone does not settle that choice.
Choose Dell Alienware AW3426DW for warranty and support service and value for money.
Choose LG 39GX950B-B for HDR adjustment controls and built-in speakers.
Scores are out of 5. Missing scores mean missing review evidence, not a missing feature.
The included three-year coverage for OLED burn-in is a valuable reassurance for long-term ownership.
The two-year panel warranty feels short beside common three-year OLED coverage, with burn-in terms not always clearly promoted.
The newest QD-OLED image quality at around the original $800 launch price impresses many testers, though some would pay more for richer connectivity.
The OLED picture quality is top-tier, but its premium price and cheaper competitors make the value proposition hard to defend.
Many PC titles benefit from the wider view, but unsupported games, menus and cutscenes still introduce black bars, cropping or smaller active images.
Standard 16:9 console or video sources can display correctly with black sidebars instead of stretched proportions.
Multiple HDR modes are available, but limited brightness-curve adjustments and locked controls restrict fine tuning.
High, low, and uniform brightness options provide useful control, but achieving the best balance requires choosing settings for the content.
Preset calibration is strong, but locked white-balance controls and limited per-mode adjustments frustrate some advanced tuning workflows.
Hardware calibration and selectable sRGB/DCI-P3 presets give unusually flexible options for tailoring color, despite some locked settings.
Alienware Command Center provides convenient desktop control of display settings, with reported stability improvements over earlier versions.
LG’s desktop software makes adjusting settings easier than using the monitor controls, despite a brief loading delay.
The True Black mode tends to preserve accurate scene brightness, while peak modes can dim bright scenes or overbrighten dark ones. Careful mode choice matters.
HDR presets trade accuracy against brightness and saturation, with some modes overbrightening shadow and midtone content.
There are no integrated speakers, so games and videos require an external audio solution. Several testers consider that an inconvenient omission.
The integrated speakers are a welcome convenience for consoles and occasional listening, though they are not substitutes for dedicated audio.
Passive cooling avoids fan noise; one side-by-side tester measured more warmth at maximum output but found better temperature behavior at matched brightness.
The rear can become noticeably hot after extended sessions, although high heat is understandable for this demanding panel.
3440×1440 suits immersive gaming and side-by-side windows without 4K's graphics demands, but it cannot match the text detail of higher-density 4K screens.
The 5120×2160 5K2K resolution is a major upgrade over earlier 39-inch ultrawides, bringing finely detailed games and substantially sharper desktop content.
The semi-gloss surface keeps images crisp and avoids a grainy matte look even as it improves glare resistance.
The matte finish reduces mirror reflections but does not deliver quite the crystalline sheen favored by fans of glossy OLED.
Dark-shade handling is usually good and can be improved with presets, though some HDR modes crush or coarsen the very darkest steps.
Dark-scene detail is generally well preserved, with black-level adjustments available to bring out shadow information.
The downstream USB-C port can top up small devices at 15W, but cannot replace a charging laptop dock.
USB-C video and up to 90W charging make a convenient connection for compatible laptops and other desk devices.
The 3440×1440 resolution is easier to drive than 4K, though reaching 280 frames per second still calls for a capable gaming PC.
Driving eleven million pixels at high frame rates requires substantial graphics horsepower, so weaker systems will need major compromises.
The stand supports the broad screen securely with little wobble, even during menu navigation and some vibration-heavy testing.
The stand is solid enough in ordinary use but the big panel can wobble when touched or operated.
True Black, Peak 1300, Peak 1300 Bright and Dolby Vision give users several looks to choose from. None perfectly balances peak punch with accuracy in every scene.
Different HDR presets offer distinct brightness and saturation looks, although none combines every desirable accuracy characteristic.
4K 120Hz console signals, VRR and HDR can work with the right settings, but the ultrawide ratio introduces side bars and the lack of audio output complicates hookups.
Modern consoles work well with the display at 16:9, although their lack of ultrawide output means black sidebars.
The small hub is handy for peripherals and light charging, but two downstream ports and one upstream connection are basic for the class.
The small USB-A hub adds convenience, although routing its upstream signal through USB-C may complicate some desktop/laptop combinations.
Two HDMI 2.1 inputs and DisplayPort cover core video needs, while limited USB, no audio jack and no video-capable USB-C leave the hub side basic.
Modern DisplayPort, HDMI, USB-C, and USB-A ports cover many setups, though a missing KVM and certain USB routing limitations temper flexibility.
Automatic pixel shifting and a stronger panel help address OLED image retention, but the menu exposes few manual care settings. The warranty provides additional reassurance.
OLED-care options are basic compared with rival premium monitors, and prolonged static desktop content still calls for caution.
The panel is consistently even across the screen, without the gray banding or dirty-screen effect seen on some rivals.
Most tested samples showed little distracting banding in routine use, though dark-gray banding can vary between panels or modes.
At 280Hz the screen feels extremely smooth and offers a useful step up from older models. It deliberately stops short of pricier 360Hz esports-focused options.
Native 165Hz is fluid for detailed 5K2K gaming, but lower than some flagship alternatives; 330Hz demands a drop to 2560×1080.
Wide DCI-P3 coverage delivers brilliant, saturated game and film color, and well-chosen presets can keep standard content natural.
Coverage of modern wide color spaces is extensive, producing vibrant games and HDR imagery even if a few saturated colors remain outside its reach.
RGB-stripe pixels improve the clarity of text and fine UI elements, although 110 PPI remains softer than a 4K alternative and one test recommends reducing default edge enhancement.
Fine detail in games and desktop apps is one of its signature strengths, particularly compared with 3440×1440 ultrawides.
Useful game presets, dark-scene enhancements, crosshairs and an esports layout cover the essentials. Flagship extras such as strobing are absent.
Useful gaming aids and dual-mode are available, but absent anti-flicker, KVM, and black-frame-insertion functions leave the feature set uneven.
Fast OLED pixels and 280Hz refresh deliver exceptionally crisp movement, even if 360Hz alternatives offer a small competitive edge.
Instantaneous OLED transitions produce remarkably crisp motion, especially at 330Hz, with some refresh-rate limitations relative to faster OLEDs.
The new RGB-stripe structure largely fixes the colored outlines around fine text that bothered older QD-OLEDs, although one tester still noticed some fringing.
High pixel density makes text generally crisp, although white-subpixel fringing is still visible to some people; RGB-stripe rivals can look cleaner.
Mode changes can require occasional manual intervention, and a few reports describe signal interruptions or mismatched color settings.
The best HDR and SDR looks can require separate picture presets, creating extra switching work for mixed media use.
Some dark scenes, menus and a video-editing app showed VRR flicker or gamma shifts, although several users did not find it distracting during games.
Frame-rate swings can cause visible flickering in dark scenes, especially in the 330Hz mode, without an anti-flicker adjustment to mask it.
The latest OLED stack offers higher brightness without conspicuous power penalties; practical consumption is reasonable for this size and speed.
Tandem WOLED has surprisingly restrained consumption in full-white usage for a panel this large.
The revised anti-reflective coating noticeably cuts the old magenta tint and distracting glare. Direct reflections still matter more than on some WOLED alternatives.
The matte anti-glare coating does a convincing job diffusing reflections, especially for a curved display, though direct sunlight can still distract.
The gently curved 34-inch screen gives games a wider, immersive feel without the distortion of more aggressive curves. A few people would prefer an even deeper wraparound.
The gentler 1500R curve draws in the edges for immersive play without the distortion and discomfort associated with LG’s earlier 800R curves.
Height, tilt and swivel adjustments are smooth and flexible enough for most workstations, but portrait rotation is not a stand option.
Height, tilt, and swivel help tailor ergonomics; some users found the height mechanism stiff or noted wobble during adjustments.
At its full refresh rate, input responsiveness is excellent and generally imperceptible in play, though one measurement set found somewhat higher low-refresh latency.
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.
The monitor earns enthusiastic recommendations as an approachable high-end OLED ultrawide, with connectivity and some specialist features trimmed to contain the price.
Its cinematic OLED image and unusually useful 39-inch format impress strongly, though price and several feature compromises limit the value proposition.
G-SYNC, FreeSync and VESA VRR provide broad PC support and smooth frame pacing across suitable devices.
FreeSync and G-SYNC-compatible operation help limit tearing across a broad range of PC and console refresh rates.
Self-lit OLED pixels produce strikingly deep blacks in dark rooms, while the new coating reduces the old purple-black tint under room lighting. Strong direct light can still wash blacks somewhat.
True OLED blacks look inky and deep, with Tandem WOLED generally retaining their depth under ambient light better than QD-OLED rivals.
Small HDR highlights can be unusually bright and finely defined, although the most aggressive modes may sacrifice detail or overall scene brightness.
Bright effects look striking and fine HDR details generally remain visible, but aggressive tone-mapping settings can sacrifice accuracy.
The 21:9 canvas creates a wide, cinematic view and extra horizontal working space. Not every game or console output fills it cleanly.
The 21:9 format expands game views and workspace substantially; standard 16:9 inputs need side borders rather than full-screen stretching.
A wider field of view and gentle curvature add real immersion in compatible PC games, with black bars or unsupported scenes remaining occasional frustrations.
The 21:9 curved screen supplies a wide field of view and deep immersion, especially in games that natively support ultrawide layouts.
The flat stand is generally practical for keyboards and other peripherals, although its broad base and the display's width still need desktop space.
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.
Unlike some higher-priced rivals, this model omits a black-frame-insertion option for further reducing perceived blur.
A dedicated black-frame-insertion mode is missing, leaving a gap for gamers who want further sample-and-hold blur reduction.
Per-pixel illumination avoids the bright halos and blooming that can surround highlights on LCD and mini-LED displays.
Independent OLED pixels eliminate the halos and backlight blooming that can appear on LCD and Mini-LED screens.
Fast response and a simulated smaller-screen esports option are real strengths. Players who prioritize 16:9 layouts or refresh rates above 280Hz may prefer a dedicated esports monitor.
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 fifth-generation Penta Tandem QD-OLED panel is central to the appeal, providing brighter HDR, deeper-looking blacks under ambient light and far more legible text than older designs.
The fourth-generation Tandem WOLED panel offers deep pixel-level blacks, much stronger brightness than older WOLED ultrawides, and rich color.
Native 3440×1440 PC gaming is this display's strongest role, pairing wide-screen immersion with excellent motion and rich HDR.
PC gaming is excellent with a sufficiently powerful GPU, unlocking full 21:9 views, 5K2K detail, and rapid OLED motion.
Near-instant OLED pixel transitions keep fast action clear and make the monitor feel exceptionally responsive.
Extremely fast pixel transitions keep moving objects clear with little conventional ghosting or smearing.
Deep blacks, striking highlights and a wraparound field of view make story-driven and atmospheric games a particular strength.
Atmospheric and cinematic games flourish on the large, sharp OLED, with high contrast and impressive HDR lighting.
DisplayPort 1.4 with compression handles native gaming well, but enthusiasts miss the newer DisplayPort 2.1 bandwidth and uncompressed option.
Full-bandwidth DisplayPort 2.1 UHBR20 is a standout, capable of 5K2K at 165Hz without relying on compression from compatible hardware.
Factory sRGB calibration can be exceptionally accurate, particularly in Creator mode. The default wide-gamut setting may oversaturate standard SDR material.
The sRGB and calibrated modes can be accurate, but default wide-gamut settings may oversaturate SDR colors and some presets require tuning.
There is no integrated KVM switch for sharing peripherals between computers, a notable compromise compared with more fully equipped competitors.
A built-in KVM is missing, disappointing those hoping to share peripherals between multiple computers.
PiP/PbP options are genuinely useful for split-screen viewing and working across two inputs, with convenient positioning controls.
Displaying two inputs at once helps multi-device use, though refresh rate can drop when sharing the panel between a Mac and PC.
The joystick is responsive and the menu generally easy to navigate, although its numerous layers and sometimes jagged text draw occasional complaints.
The on-screen controls are approachable and the LG software simplifies management, although some menu choices and the interface style divide opinion.
The five-layer panel is noticeably brighter in SDR and produces vivid, high-impact HDR highlights. Large bright HDR scenes remain more constrained than small specular effects.
For an OLED ultrawide, brightness is excellent in both SDR and HDR, although sunny windows and larger bright scenes can still expose limits.
Desktop brightness is fairly steady, but high-peak HDR modes can dim brighter full-screen scenes. The modes trade consistency against dramatic small highlights.
Uniform brightness controls tame distracting OLED luminance changes, though brighter presets can still dim as content changes.
The Dark Stabilizer can reveal enemies and objects in shadowy games without lifting blacks completely. Higher levels sacrifice some dark-scene atmosphere.
The black stabilizer can make dark objects easier to distinguish without unnecessarily lifting the OLED black floor.
OLED contrast and brighter highlights produce outstanding HDR overall, with the usual tradeoff between full-scene brightness and extreme peaks.
Tiny highlights look punchy against OLED blacks and HDR games can be spectacular; mode calibration and full-screen luminance are not flawless.
Adaptive Sync, G-SYNC, and FreeSync keep gameplay fluid and largely tear-free. A few accounts distinguish this smoothness from occasional OLED VRR flicker.
Adaptive sync works smoothly in tested gaming scenarios, helping avoid tearing and supporting variable frame rates.
Near-perfect OLED contrast lends depth to dark games and HDR scenes, especially compared with conventional LCD panels.
Pixel-level OLED control delivers extraordinary contrast and depth, especially alongside bright effects in otherwise dark scenes.
Fanless ventilation avoids the whir that can accompany some actively cooled OLED competitors.
The internal cooling fan is nearly inaudible in normal use, with noise noticeable only at extremely close range.
The newer QD-OLED panel combines vivid color, richer contrast, stronger brightness and cleaner text into an impressive all-round image.
Image quality is outstanding with razor-sharp detail, brilliant OLED blacks, and impactful color and HDR.
Well-calibrated Creator modes track their targets closely, while some default or boosted modes can appear slightly too dark or too contrasty.
Gamma is reasonably controllable, but several factory and HDR settings shift dark or midtone brightness away from the intended target.
The chassis feels solid and well assembled, with a stable stand despite a restrained plastic exterior.
Materials and construction are generally solid, although the large display can move on its stand when nudged.
The 34-inch width offers a sweet spot for immersion and multitasking, though its limited height may feel smaller to owners of taller 32-inch displays.
The 39-inch format gives noticeably more vertical presence than 34-inch ultrawides without the imposing dimensions of a 45-inch panel.
The understated dark-indigo shell looks sleek and office-friendly, though opinions divide on its blue color and lack of the older Alienware styling.
A restrained chassis, slim bezels, and understated stand give the large OLED a clean, polished appearance.
Clearer text reduces reading fatigue for some owners, but the menu lacks a dedicated low-blue-light mode and flicker-sensitive users should take care.
A warmer Reader mode and hardware low-blue-light provisions make lengthy text sessions more comfortable.
The central joystick and straightforward physical controls make ordinary setup and adjustment quick.
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.
Small illuminated Alienware accents are customizable and subtle. They will disappoint anyone seeking dramatic desk-filling RGB effects.
A cutout in the stand keeps power and video cables tidier, though the solution is simple rather than elaborate.
One detailed hands-on sample arrived with its protective film intact and no shipping-related micro-scratches.
The monitor accommodates PC, Mac, and current console connections, even though each uses different optimal display modes.
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.
Genre presets and Creator mode offer accessible ways to tune the picture, although the default options sometimes work better than extensive adjustments.
Extremely fast OLED transitions keep motion clean, with little smearing, overshoot or visible ghosting even in fast games.
Most real-world gradients look smooth with little banding, but near-black fades can reveal coarser steps in some HDR settings.
With no headphone or audio-out connection on the monitor, wired audio must run directly from a computer, console or another device.
AI upscaling can sharpen certain low-resolution console signals, but PC use is inconsistent or impractical and cannot replace modern GPU upscaling.
A direct power cord avoids a bulky external brick, helping keep the desk and floor tidier.
The monitor worked reliably with a Mac, including dual-mode, making it practical as part of a mixed Mac/PC desk.
The extremely fast OLED pixels reduce smearing and ghosting, keeping movement crisper than typical LCD screens at comparable refresh rates.
Improved text rendering and strong factory color modes help with editing, but color-critical Adobe RGB workflows may need outside calibration.
At roughly 143 PPI, this monitor approaches the text sharpness of a 32-inch 4K display while offering much more horizontal room.
Audio is serviceable at ordinary volumes but lacks bass and can turn thin with demanding music or movie soundtracks.
Bottom-edge USB-A and USB-C ports are easy to reach without feeling behind the monitor, though permanently attached cables can be visible.
Standard 100×100mm VESA support makes swapping to a monitor arm simple, useful for saving space or custom setups.
Common 24, 25, 50 and 60 fps video plays without obvious skips or cadence judder.
Color and uniformity hold up well off axis, as expected from a strong QD-OLED panel.
AI audio enhancement receives mixed-to-negative reactions: voices may become clearer, but compression artifacts and compatibility limits reduce its usefulness.
The harder new surface is less susceptible to fine scratches during cleaning than earlier generations of QD-OLED coatings.
Colors are impressive overall, but the white-subpixel design cannot match the brightest saturated colors available from some QD-OLED competitors.
Mode switching is generally convenient, though one review encountered rare Windows layout problems when leaving dual-mode.
The DisplayPort bandwidth allows native 5K2K at the full refresh rate without DSC, whereas other inputs may still need compression.
A simulated 25-inch active area makes fast competitive play easier to focus on while retaining 280Hz. A few testers saw dimmer output or questioned whether the smaller image was worth it.
Pixel-level control makes bright and dark areas coexist cleanly without the blooming associated with zone-based backlights.
Dolby Vision adds useful flexibility for compatible games, consoles and movies, although PC support is spotty and mode behavior sometimes needs attention.
HDMI 2.1 connectivity suits modern consoles and PCs and supports high-resolution, high-refresh video feeds.
Tool-free stand assembly is quick, while the physical adjustments make positioning straightforward.
One test found a PWM frequency that may bother especially sensitive viewers, even while typical gaming looked fine.
The stronger coating should stand up better to routine wiping and incidental contact than earlier scratch-prone QD-OLED surfaces.
