LG’s 45GX950A-B is one of the rare 45-inch ultrawide OLED monitors that doesn’t force you to choose between sharp productivity visuals and high-speed competitive gaming. With a massive 5120 x 2160 “5K2K” resolution, this curved OLED gaming monitor delivers a noticeably crisper image than most ultrawide rivals, and it can even switch into a faster, lower-resolution mode when refresh rate matters more than pixel count.
Right now, the 2025 LG 45GX950A-B is being sold at a significantly reduced price, dropping to $1358.99 during an end-of-year Amazon sale (a discount of more than $640). There’s also an extra incentive for eligible buyers using a Prime credit card, which can add 10% cashback on top of the reduced price.
A standout feature is the monitor’s dual-mode flexibility. In its highest-quality setting, you get the full 5K2K 5120 x 2160 resolution for immersive gaming, detailed editing work, and clearer multitasking across multiple windows. When you want maximum responsiveness for fast-paced esports or twitch shooters, the display can shift to a WFHD 2560 x 1080 mode that reaches a 330Hz refresh rate. That combination is what makes this model appealing to both gamers and creators: it can feel like a productivity display during the day and a high-refresh gaming panel at night.
The first thing you’ll notice is the intense 800R curvature. On paper it sounds extreme, but the idea is simple: curve the screen enough that the edges remain within a more natural field of view, reducing the need to constantly turn your head when you’re working across a wide timeline or scanning a large game HUD. Still, it’s not a fit for every desk. This 45-inch curved ultrawide has a large footprint, so space and viewing distance matter more than they do with a flatter 34-inch or 27-inch setup.
Where the LG 45GX950A-B separates itself from many ultrawide OLED options is pixel density and clarity. Many big ultrawides look softer when they aren’t pushing 4K-class resolution, but the 5K2K panel here helps preserve detail. With around 125 PPI, text and UI elements look sharper than on typical 45-inch gaming ultrawides, though some users still report mixed experiences with text fringing—something that can vary by settings, viewing distance, and individual sensitivity.
For gaming, hardware demands are worth considering. Running modern games at 5120 x 2160 with high frame rates requires extremely powerful graphics performance, and it’s the kind of resolution that can quickly expose GPU limits. The 330Hz lower-resolution mode is a practical alternative for competitive players who would rather max out refresh rate and frame consistency than chase ultra-high pixel counts. Another consideration is aspect ratio support: because this is a 21:9 ultrawide, games that don’t properly support that format may show black bars.
As an OLED monitor using a WOLED panel, it delivers the traits people buy OLED for—deep blacks, strong contrast, and excellent perceived image depth. Color accuracy is also described as outstanding, making the screen a compelling option for creative professionals who want a large canvas for photo work, video editing, and design. The main trade-off is brightness in SDR, which can lag behind some IPS alternatives, especially in brighter rooms.
Connectivity is also a strong point. The monitor includes modern ports such as DisplayPort 2.1 plus USB-C with power delivery, making it easier to integrate into a high-end gaming PC setup or a workstation workflow without juggling extra adapters.
Even at $1358.99, it’s still a premium purchase. But for buyers who want one display that can realistically replace a multi-monitor setup—while also doubling as a high-refresh competitive gaming screen—the LG 45GX950A-B stands out as a uniquely versatile 45-inch 5K2K curved OLED gaming monitor.
