As one of the world’s biggest panel manufacturing brands, LG continues to push the boundaries of what is possible, and the LG UltraGear 45-inch GX950A-B.AAU WUHD monitor is no exception. Boasting the world’s first 5K2K panel, it delivers an immersive, curved window into your games, with the performance and clarity to match.

The first thing that hits you is the sheer presence of the panel; 45 inches with an 800R curve. Wrapping neatly around your field of view, it creates a truly cinematic feel, whether you’re gaming or multitasking. Despite its size, the monitor’s design feels refined rather than overwhelming. The matte black finish, subtle hexagon lighting on the rear, and premium stand combine to give it that unmistakable UltraGear aesthetic.

The standout feature here, of course, is the OLED panel. With a native resolution of 5120 x 2160 and 125 pixels per inch, the image sharpness is immediately noticeable. Text looks crisp, and colours are beautifully represented with minimal bleeding. It’s great for productivity or creative work, and the extra horizontal resolution means more workspace without needing a dual-monitor setup.

Gaming, however, is where this display really flexes. The OLED panel produces phenomenal contrast, with deep, inky blacks, and achieves a staggering contrast ratio of 1.5 million to 1. Colours burst with vibrancy, covering 98.5% of the DCI-P3 colour gamut, and the HDR True Black 400 certification gives scenes incredible depth and realism. While playing Cyberpunk 2077, I immediately noticed that scenes felt more cinematic, with deep shadows and bright colouration, and during action sequences, it popped with energy and motion.

Dual Mode is a particularly interesting feature, allowing you to switch between 5K2K at 165Hz for visual fidelity or WFHD at 330Hz for added responsiveness. It’s like having two monitors in one; one for immersive adventure games and another tuned for competitive esports. The transition between the two modes is seamless, and while 330Hz might sound like overkill to some, the difference in input responsiveness is immediately noticeable.

A 0.03ms response time, combined with compatibility with FreeSync Premium Pro and G-Sync, ensures near-instant pixel transitions, eliminating blur and ghosting during rapid movement. Gameplay feels buttery smooth, and regardless of whether you’re playing on PC or console, the visual fluidity remains consistent and impressive.

Even in bright rooms, reflections are minimised thanks to an anti-glare coating, and eye strain is significantly reduced during longer sessions, thanks to its low blue light certification. For both gaming marathons and creative workloads, that’s a subtle but appreciated quality-of-life improvement.

Every modern gaming setup is covered, with a DisplayPort 2.1, two HDMI 2.1ports, and A USB Hub. The USB hub includes two USB Type-A downstream ports for peripherals, and a USB Type-C upstream port, which can also be used for 90W power delivery. It also includes a built-in KVM switch, allowing control of multiple systems with one set of peripherals, making it perfect for streamers or anyone juggling a work and gaming rig.

The built-in speakers are surprisingly solid, with DTS Headphone:X support adding an extra layer of immersion when using a good headset. The 4-pole headphone jack is also a nice touch, allowing you to plug in a gaming headset directly without sacrificing mic support.

Despite its large footprint, it’s stable and surprisingly easy to reposition, offering height, tilt, and swivel adjustments, though smaller desks may struggle to accommodate its width comfortably. While the 800R curve feels natural once you’re seated, I did notice that items located towards the edge of the screen seemed to compress when viewed from an angle, but this is fairly normal behaviour for a curved wide screen. Its power consumption is also fairly low for its size, rated at 66W, but it does use an external power brick, which I’ve previously mentioned I’m not overly fond of.

I have other concerns around OLED technology in general, as I have mentioned in other reviews. They tend to get quite warm and can suffer from screen burn if not properly cared for. LG has implemented standard protections, such as pixel shifting, screen savers, and dimming features, but long static HUDs or desktop layouts could still pose a risk of damaging the panel.

While I’m not normally a fan of ultra-wide monitors, I can confidently say that the LG UltraGear 45-inch GX950A-B.AAU WUHD monitor delivers exactly what it promises. It is easily one of the most versatile gaming displays on the market, making it ideal for anyone who wants both cinematic immersion and competitive speed without compromise.

Whether you’re exploring lush open worlds, dominating FPS games, or fine-tuning a video edit, the blend of OLED vibrancy, 5K2K resolution, and high refresh rates makes it an absolute standout.
