LG UltraGear Evo 39GX950B-B: The Two-Minute Review
It is difficult to describe the LG UltraGear Evo 39GX950B-B as anything short of phenomenal. It serves as an impressive goal for PC gamers striving for premium visual quality, combining an immersive 21:9 aspect ratio with crisp image clarity delivered by its 5K2K (5120x2160) display resolution.
The monitor utilizes a 4th-generation tandem OLED panel, known for sustained high brightness levels, reduced burn-in risk, and improved power efficiency, which benefits both extended gaming sessions and daily productivity tasks.
The 39GX950B-B includes settings to address brightness uniformity and Automatic Brightness Limiter (ABL) behaviors common to OLED screens. The On-Screen Display provides high, low, and uniform brightness configurations to help manage ABL during varied usage.
Source reviews noted that ABL was barely noticeable during dynamic gaming scenarios like Horizon Forbidden West, though it can become more apparent when frequently opening and closing multiple windows on a standard desktop environment.
Operating at 5K2K resolution means driving roughly 33% more pixels than standard 4K, which places heavy demands on graphics hardware. Utilizing this monitor effectively requires a powerful GPU, such as an RTX 4080 Super, RTX 5070 Ti, or higher, to maintain strong frame rates without relying entirely on upscaling.
Consequently, committing to a 5K2K display implies a long-term requirement for high-end graphics cards unless future mid-range GPU performance generations advance rapidly.
To mitigate hardware strain, the monitor features a 1080p Dual Mode supporting a 2580x1080 resolution alongside a 330Hz refresh rate and built-in AI upscaling, offering competitive gamers an alternative option for high frame rates.
While native upscaling tools are integrated for non-native input signals, users with powerful desktop GPUs will likely continue relying on software-based solutions like DLSS.
Overall, the LG 39GX950B-B excels at delivering immersive experiences with peak HDR brightness up to 1,500 nits in small highlights, though its high market price represents a notable barrier.
LG UltraGear Evo 39GX950B-B: Price & Availability
How much does it cost? $1,799.99 / £1,599.99 / around AU$2,799
When is it available? Available now
Where can you get it? Available in the US, UK, and Australia
The primary drawback of the LG UltraGear Evo 39GX950B-B is its high retail price, placing it out of reach for many consumers, particularly when alternatives like the Alienware AW3926QW offer lower entry costs.
The overall expense is further compounded for PC users who may need to upgrade their entire system components to support the extreme display resolution.
When factoring in a capable PC build alongside the monitor, the total investment easily exceeds standard budget thresholds, limiting its accessibility.
The introduction of cheaper competing options has placed additional pressure on LG's pricing strategy for this high-end hardware.
Adjusting the recommended retail price closer to competitors would significantly improve the monitor's market competitiveness.
LG UltraGear Evo 39GX950B-B: Design
The 39GX950B-B features a sturdy monitor stand with robust height, tilt, and swivel adjustment flexibility, matching the reliable build quality of other UltraGear Evo displays.
Unlike some competing glossy screens, this model utilizes a matte anti-glare finish, which effectively handles bright, sunlit room conditions without introducing distracting reflections.
The On-Screen Display features a refreshed layout with illustrative category icons that elevate the user experience.
Additionally, the inclusion of a 90W Power Delivery USB-C port provides convenient charging capabilities for connected laptops and peripherals.
Built-in dual 7W internal speakers offer a practical audio solution, particularly useful for console setups like the PS5 that lack native Bluetooth audio support.
A notable physical observation is the elevated operating temperature after several hours of heavy use, which remains understandable given the dense pixel array and high peak brightness.
LG UltraGear Evo 39GX950B-B: Features
The monitor provides an extensive feature set designed to manage the heavy demands of 5K2K rendering.
AI-driven upscaling options assist systems that struggle with native 5K2K output by processing lower base resolutions efficiently.
Combining upscaling features with Dual Mode gives users flexibility while planning hardware upgrades.
Dual Mode supports 2560x1080 at 330Hz, catering directly to fast-paced competitive titles.
Brightness settings allow users to tailor output depending on content type, keeping high modes reserved for vibrant games while utilizing uniform settings for cinematic viewing.
LG UltraGear Evo 39GX950B-B: Performance
Performance on the LG UltraGear Evo 39GX950B-B is exceptional, driven by the 4th-generation tandem OLED panel which yields deep black levels, high contrast ratios, and striking HDR output.
Testing across well-optimized titles highlighted the monitor's ability to render complex lighting and detailed environments accurately.
Games such as Horizon Forbidden West demonstrated stellar visual fidelity, maintaining image sharpness when paired with upscaling technologies.
The 5K2K ultrawide format expands the field of view significantly, greatly improving immersion and fine detail rendering in foliage and character models.
Dynamic Tonemap features helped preserve highlight details in bright sequences that typically suffer on older OLED panels.
Although the refresh rate drops to 165Hz compared to some 1440p predecessors, the substantial jump in pixel density and sharpness easily outweighs the difference.
Text clarity remains sharp despite using a white subpixel layout instead of an RGB stripe format, largely thanks to the high pixel density of the 5K2K resolution.
Buy the LG UltraGear Evo 39GX950B-B if...
You want one of the best ultrawide gaming monitors available. Its 5K2K resolution and advanced OLED panel provide a visually stunning experience that transforms compatible games.
You want an immersive display that preserves desk space. Compared to larger 45-inch monitors, the 39-inch form factor hits a sweet spot for immersion without dominating your workspace.
Don’t buy it if…
You are looking for an affordable monitor. The high price tag is difficult to justify given cheaper alternatives currently on the market.
You do not own a powerful GPU. Running games at 5K2K requires substantial graphics processing power unless you rely heavily on upscaling features.
