-
The 5120×2160 5K2K resolution is a major upgrade over earlier 39-inch ultrawides, bringing finely detailed games and substantially sharper desktop content.
-
At roughly 143 PPI, this monitor approaches the text sharpness of a 32-inch 4K display while offering much more horizontal room.
-
The 39-inch format gives noticeably more vertical presence than 34-inch ultrawides without the imposing dimensions of a 45-inch panel.
-
Fine detail in games and desktop apps is one of its signature strengths, particularly compared with 3440×1440 ultrawides.
-
The 21:9 curved screen supplies a wide field of view and deep immersion, especially in games that natively support ultrawide layouts.
-
Pixel-level OLED control delivers extraordinary contrast and depth, especially alongside bright effects in otherwise dark scenes.
-
Its cinematic OLED image and unusually useful 39-inch format impress strongly, though price and several feature compromises limit the value proposition.
-
True OLED blacks look inky and deep, with Tandem WOLED generally retaining their depth under ambient light better than QD-OLED rivals.
-
Tiny highlights look punchy against OLED blacks and HDR games can be spectacular; mode calibration and full-screen luminance are not flawless.
-
PC gaming is excellent with a sufficiently powerful GPU, unlocking full 21:9 views, 5K2K detail, and rapid OLED motion.
-
The 21:9 format expands game views and workspace substantially; standard 16:9 inputs need side borders rather than full-screen stretching.
-
The gentler 1500R curve draws in the edges for immersive play without the distortion and discomfort associated with LG’s earlier 800R curves.
-
The matte anti-glare coating does a convincing job diffusing reflections, especially for a curved display, though direct sunlight can still distract.
-
Full-bandwidth DisplayPort 2.1 UHBR20 is a standout, capable of 5K2K at 165Hz without relying on compression from compatible hardware.
-
Bright effects look striking and fine HDR details generally remain visible, but aggressive tone-mapping settings can sacrifice accuracy.
-
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.
-
Image quality is outstanding with razor-sharp detail, brilliant OLED blacks, and impactful color and HDR.
-
Extremely fast pixel transitions keep moving objects clear with little conventional ghosting or smearing.
-
For an OLED ultrawide, brightness is excellent in both SDR and HDR, although sunny windows and larger bright scenes can still expose limits.
-
Height, tilt, and swivel help tailor ergonomics; some users found the height mechanism stiff or noted wobble during adjustments.
-
USB-C video and up to 90W charging make a convenient connection for compatible laptops and other desk devices.
-
Independent OLED pixels eliminate the halos and backlight blooming that can appear on LCD and Mini-LED screens.
-
High, low, and uniform brightness options provide useful control, but achieving the best balance requires choosing settings for the content.
-
The fourth-generation Tandem WOLED panel offers deep pixel-level blacks, much stronger brightness than older WOLED ultrawides, and rich color.
-
Atmospheric and cinematic games flourish on the large, sharp OLED, with high contrast and impressive HDR lighting.
-
Instantaneous OLED transitions produce remarkably crisp motion, especially at 330Hz, with some refresh-rate limitations relative to faster OLEDs.

-
Mode switching is generally convenient, though one review encountered rare Windows layout problems when leaving dual-mode.
Cons
Sort
-
The OLED picture quality is top-tier, but its premium price and cheaper competitors make the value proposition hard to defend.
-
The two-year panel warranty feels short beside common three-year OLED coverage, with burn-in terms not always clearly promoted.
-
A built-in KVM is missing, disappointing those hoping to share peripherals between multiple computers.
-
OLED-care options are basic compared with rival premium monitors, and prolonged static desktop content still calls for caution.
-
AI upscaling can sharpen certain low-resolution console signals, but PC use is inconsistent or impractical and cannot replace modern GPU upscaling.
-
AI audio enhancement receives mixed-to-negative reactions: voices may become clearer, but compression artifacts and compatibility limits reduce its usefulness.
-
Frame-rate swings can cause visible flickering in dark scenes, especially in the 330Hz mode, without an anti-flicker adjustment to mask it.
-
Driving eleven million pixels at high frame rates requires substantial graphics horsepower, so weaker systems will need major compromises.
-
HDR presets trade accuracy against brightness and saturation, with some modes overbrightening shadow and midtone content.
-
The reduced esports-size window works, but the small active area and coarse lower-resolution image are awkward on such a large panel.
-
A dedicated black-frame-insertion mode is missing, leaving a gap for gamers who want further sample-and-hold blur reduction.
-
The rear can become noticeably hot after extended sessions, although high heat is understandable for this demanding panel.
-
The best HDR and SDR looks can require separate picture presets, creating extra switching work for mixed media use.
-
Automatic picture adjustment may suit hands-off users, but it can upset creators who need stable color and brightness settings.
-
Audio is serviceable at ordinary volumes but lacks bass and can turn thin with demanding music or movie soundtracks.
-
Gamma is reasonably controllable, but several factory and HDR settings shift dark or midtone brightness away from the intended target.
-
Colors are impressive overall, but the white-subpixel design cannot match the brightest saturated colors available from some QD-OLED competitors.
-
The matte finish reduces mirror reflections but does not deliver quite the crystalline sheen favored by fans of glossy OLED.
-
The small USB-A hub adds convenience, although routing its upstream signal through USB-C may complicate some desktop/laptop combinations.
-
Different HDR presets offer distinct brightness and saturation looks, although none combines every desirable accuracy characteristic.
-
Useful gaming aids and dual-mode are available, but absent anti-flicker, KVM, and black-frame-insertion functions leave the feature set uneven.
-
Standard 16:9 console or video sources can display correctly with black sidebars instead of stretched proportions.
Use Cases
