The 39-inch UltraGear 39GX950B-B pairs a sharp 5K2K OLED panel with 330Hz dual-mode gaming, but its £1,599.99 price and demanding hardware requirements limit its appeal.
LG’s 39GX950B-B sits in a narrow but growing category of premium gaming displays: large ultrawide OLED monitors built for players who want both speed and cinematic scale. TechRadar’s review describes it as a 39-inch, 5K2K panel with a 21:9 aspect ratio, and that combination gives it a sharper image than lower-resolution ultrawides while still preserving the immersion that makes the format appealing. RTINGS also highlights its strong contrast, deep blacks and detailed image quality, reinforcing the impression that this is a monitor aimed at enthusiasts who care as much about visual fidelity as frame rate.
The panel’s headline feature is its 4th-generation tandem OLED technology, which LG uses to improve brightness efficiency and reduce the risk of OLED wear over time. TechRadar says the screen can reach 1,500 nits in small highlights, with brightness settings designed to help users manage the automatic brightness limiting that is common on OLED displays. In practice, that matters because the monitor is not just for games: it is also pitched as a display for films and general desktop use, where brightness shifts can be more noticeable. COMPUTER BILD similarly praises the sharp, high-contrast picture, although it notes that colour accuracy and reflections are not entirely free of compromise.
The trade-off is that this level of performance comes with demanding hardware requirements. GeekChamp notes that 5K2K pushes significantly more pixels than standard 4K, making a powerful graphics card important if users want to sustain high frame rates without depending too heavily on upscaling. TechRadar comes to the same conclusion, pointing out that the monitor is best paired with high-end GPUs such as Nvidia’s RTX 4080 Super-class hardware or better. LG tries to ease that burden with a dual-mode option that drops the resolution to 2560×1080 while raising the refresh rate to 330Hz, which makes the screen more practical for competitive play.
That flexibility is a key part of the 39GX950B-B’s appeal. LG’s own launch material, as well as coverage from Tom’s Hardware and PC Gamer, present the monitor as one of the first of its kind: a curved 39-inch 5K2K OLED with AI-assisted features and a strong gaming focus. TechRadar found the AI upscaling tools useful for lower-resolution inputs, particularly for users running older hardware or consoles, while the monitor’s 90W USB-C charging, adjustable stand and built-in speakers broaden its usefulness beyond pure gaming. The design is also meant to be practical, with a matte anti-glare coating and ergonomic adjustments that make it easier to live with on a desk than some glossy rivals.
Price remains the most obvious barrier. TechRadar says the 39GX950B-B launches at $1,799.99 in the US, £1,599.99 in the UK and about AU$2,799, which puts it well above some direct competition, including Alienware’s cheaper 39-inch 5K2K alternative. That leaves LG’s model in a difficult position: it is widely regarded as one of the best-looking gaming monitors available, but it is also an expensive one, and the full cost of ownership can rise further once the need for high-end PC hardware is taken into account. For buyers who want the very best image quality and are prepared to pay for it, though, it appears to set a high benchmark.
