LG’s UltraGear 45GX950A B gaming monitor is now available with a substantial 26 percent discount on Amazon. The price cut makes the premium 45 inch OLED display more accessible to gamers and professionals who want high resolution, fast refresh rates, and a large workspace in one monitor.
The main attraction is LG’s dual mode technology. You can run the display at its native 5120 × 2160 resolution with a refresh rate of up to 165Hz, which is well suited to visually demanding games, creative applications, and productivity. You can also switch to a 2560 × 1080 mode that increases the refresh rate to 330Hz for competitive games where speed and responsiveness matter more than resolution.
This flexibility allows the monitor to support several workloads without requiring a separate esports display. However, running modern games at the full 5K2K resolution will require a powerful graphics card, especially when higher graphics settings and smooth frame rates are expected.
The 5K2K OLED panel offers sharper text and detailed images
The 45 inch screen uses a wide 21:9 aspect ratio and provides a pixel density of 125 pixels per inch. That is an important improvement over earlier large ultrawide OLED monitors, where lower pixel density could make text appear less defined.
Sharper text makes the display more practical for writing, programming, video editing, and other desktop work. The improved pixel structure also helps reduce the colour fringing that can sometimes appear around text on OLED panels.
The screen has an aggressive 800R curve that places its outer edges closer to your natural field of view. This can make racing games, flight simulators, and first person titles feel more immersive. The curve also reduces the amount of head movement needed when viewing content near the edges of the large panel.

Fast response times support competitive gaming
The OLED panel has a quoted response time of 0.03ms. Individual pixels can change quickly, which helps keep moving objects clear during fast camera movement and competitive gameplay.
The monitor also supports NVIDIA G Sync compatibility and AMD FreeSync Premium Pro. These technologies help reduce screen tearing when the display refresh rate and game frame rate do not match.
In dual mode, the 330Hz setting reduces the graphics workload by lowering the resolution. This makes it easier for a capable gaming PC to produce the very high frame rates needed for competitive shooters and esports games.
OLED contrast and HDR improve darker scenes
Since each OLED pixel produces its own light, individual pixels can switch off when displaying black. This gives the monitor deep black levels and avoids the visible blooming that can occur around bright objects on some Mini LED screens.
The display carries DisplayHDR True Black 400 certification and covers up to 98.5 percent of the DCI P3 colour space. Peak brightness can reach approximately 1,300 nits in small HDR highlights, allowing bright effects to stand out against dark backgrounds.
LG has added an anti glare surface to reduce reflections in rooms with strong lighting. The monitor also supports flicker free operation and low blue light features for longer work or gaming sessions. Its stand provides height, tilt, and swivel adjustment.
Modern connections support PCs, consoles, and laptops
Connectivity includes DisplayPort 2.1, two HDMI 2.1 ports, and USB C with up to 90W power delivery. The USB C connection can carry video while charging a compatible laptop, helping reduce the number of cables required on a desk.
DisplayPort 2.1 provides additional bandwidth for high resolution and high refresh rate gaming. HDMI 2.1 also makes the monitor suitable for modern consoles, although consoles may not support its full ultrawide resolution or 330Hz mode.
The LG UltraGear 45GX950A B is best suited to enthusiasts who want one large display for immersive gaming, competitive play, content creation, and everyday productivity. Its discounted price remains premium, but the combination of 5K2K resolution, OLED image quality, and dual refresh rate modes gives it broader functionality than a conventional gaming monitor.
