The LG UltraGear 45″ Wide Quad HD 240Hz OLED is a no-compromise ultrawide gaming monitor aimed squarely at enthusiasts. With a huge 21:9 curved OLED panel, lightning-fast 240Hz refresh rate and support for both NVIDIA G-SYNC and AMD FreeSync Premium Pro, it’s clearly positioned at the premium end of the market.
At this price, you’re paying for cutting-edge display tech rather than entry-level value, but owner feedback is very strong – its 4.8 out of 5 rating from multiple reviews suggests buyers largely feel they’ve got what they paid for.
If you want a monitor that can really show off a high-end PC, particularly for immersive single-player games and competitive titles, this LG UltraGear has the specification to back up its positioning.
This monitor is best suited to PC gamers with powerful hardware who want a truly immersive setup. The 45-inch 21:9 ultrawide format and tight 800R curve wrap around your field of view, making it ideal for story-driven adventures, racing sims and flight games where immersion matters just as much as raw frame rate.
It’s a premium choice, so it will mainly appeal to enthusiasts willing to spend more on their display than on a typical office or casual gaming monitor. If you’ve already invested in a strong graphics card and want a screen that can keep up at 240Hz, this makes sense as the centrepiece of a high-end rig.
Competitive players in fast-paced shooters or battle royales will appreciate the 0.03ms response time and VRR support. Motion clarity and input responsiveness are a clear focus here, so if you’re climbing ranked ladders or playing online with friends, it gives your system room to shine.
It’s less suited to very small desks or shared spaces. The 99.3cm width and aggressive curve need room to breathe, and productivity users who prefer a flatter panel or higher resolution for text-heavy work may want something different, even though the wide 3440 x 1440 desktop is still great for multitasking.
The OLED panel is the star of the show. With a quoted 1,500,000:1 contrast ratio and VESA DisplayHDR 400 True Black certification, you get inky blacks, punchy highlights and vivid colours (98.5% DCI-P3 coverage), which makes games look rich and lifelike, especially in darker scenes.
The combination of 240Hz refresh rate and an exceptionally fast 0.03ms response time is ideal for competitive titles. It keeps motion smooth and helps to minimise blur and ghosting, so fast camera pans and hectic firefights stay clear.
Support for both NVIDIA G-SYNC and AMD FreeSync Premium Pro means variable refresh rate is covered regardless of which GPU brand you run. That helps eliminate tearing and judder, giving gameplay a more polished feel.
The 45-inch 21:9 ultrawide format and 800R curve create a very immersive setup, especially for racing, sim and open-world games. The strong curvature wraps the image around you and makes it easier to stay focused on the centre of the screen.
Practical touches like height adjustment, tilt, swivel, a built-in USB hub, anti-glare coating and HDR streaming support make it easier to live with day to day, whether you’re gaming, watching films or working across multiple windows.
This is a high-priced monitor within its category, so it’s not a sensible choice if you’re on a tight budget or running more modest hardware that can’t drive high frame rates at 3440 x 1440.
Despite the premium positioning, there are no built-in speakers. Most gamers will use a headset or external speakers anyway, but it’s worth noting if you expect sound straight from the monitor.
The 45-inch 800R curve is dramatic. While that’s great for immersion, it may feel overwhelming on a smaller desk, and not everyone will enjoy such an aggressive curvature for general productivity tasks.
Energy efficiency is only rated F, and a large OLED panel like this won’t be the most frugal choice to leave on all day, especially compared with smaller or more efficiency-focused displays.
Living with the LG UltraGear 45″ feels distinctly high-end. The wide 21:9 canvas and 45-inch size make everyday tasks like browsing, editing and multitasking feel spacious, reducing the need for a dual-monitor setup. The anti-glare screen helps keep reflections under control, so it’s usable in brighter rooms as long as you’re sensible with direct light.
The stand offers height adjustment, tilt and swivel, which makes it much easier to line up the curved panel with your seating position. That’s important with an 800R curve; when positioned correctly it feels natural and immersive, but if you sit too close or off-centre, it can feel a little overwhelming.
Setup is straightforward. You get HDMI, DisplayPort, USB and power cables in the box, plus 2 HDMI 2.1 ports and a DisplayPort input, so connecting a PC and additional devices is simple. The built-in USB hub is handy for plugging in peripherals or a USB headset, and there’s a dedicated headphone socket with DTS Headphone:X decoding for more immersive audio when using compatible headsets.
OLED panels are known for their stunning image quality but can require a bit more care to avoid static content lingering for very long periods. This monitor includes LG’s usual gaming features like Black Stabilizer and Dynamic Action Sync, plus calibration tools, to help you tune the image and get the best out of it.
Performance is where this monitor justifies its premium status. The 45-inch OLED panel delivers excellent contrast and deep blacks, so dark scenes in horror games and shadowy corners in shooters retain detail rather than turning into grey mush. With support for HDR10 and DisplayHDR 400 True Black, compatible games and videos gain extra depth and punch in highlights.
The 3440 x 1440 WQHD resolution strikes a strong balance between sharpness and performance. Text and UI elements look crisp across the 45-inch expanse, while not being as demanding on your GPU as 4K. For most high-end gaming PCs, that makes it easier to hit high frame rates at the native 240Hz refresh rate.
Motion handling is excellent on paper thanks to the 0.03ms response time. Combined with the high refresh rate and VRR support via NVIDIA G-SYNC and AMD FreeSync Premium Pro, it keeps fast gameplay feeling fluid and responsive, with less tearing and stutter. Features like Dynamic Action Sync further help to reduce input lag, which competitive players will appreciate.
LG also includes gaming-focused enhancements like Black Stabilizer, which raises visibility in darker areas without washing out the image, and dedicated Game Modes for different genres. Wide 178° viewing angles mean colours and contrast remain consistent even when you’re not sat perfectly central, which helps with such a wide panel.
Connectivity and ergonomics are well covered. You get 2 HDMI 2.1 ports, 1 DisplayPort, 2 USB ports and a built-in USB hub, plus VESA mounting support if you want to use an arm. HDR streaming support and LG Calibration Studio compatibility round out a feature set that’s clearly aimed at enthusiasts who care about image accuracy as well as speed.
This LG UltraGear sits firmly in premium territory, with a price that reflects both its size and its cutting-edge OLED technology. Compared with more conventional gaming monitors, you’re paying extra for a 45-inch ultrawide panel, very high refresh rate, and the deep contrast of OLED.
For casual gamers or those running mid-range PCs, a cheaper, smaller display may make more sense, as you won’t really exploit what you’re paying for here. However, if you’re already running a powerful graphics card and want a monitor that can keep pace at 240Hz while delivering genuinely impressive image quality, the feature set helps to justify the higher cost.
The strong 4.8/5 owner rating adds reassurance that, for most buyers, the experience lives up to expectations. Factoring in the 2-year manufacturer warranty, comprehensive gaming features, and the sheer impact of a 45-inch OLED curve, it offers good value for enthusiasts who want a standout centrepiece rather than a modest upgrade.
The LG UltraGear 45″ 240Hz OLED curved gaming monitor is a serious bit of kit aimed at gamers who want the best of both worlds: superb image quality and top-tier responsiveness. Its combination of ultrawide OLED, 240Hz refresh rate, 0.03ms response time and VRR support places it right at the sharp end of what’s currently available.
It’s undeniably expensive and the aggressive 800R curve won’t suit every desk or taste, plus the lack of built-in speakers may disappoint anyone hoping for an all-in-one solution. But if you value immersion, cinematic contrast and competitive-grade smoothness, it delivers where it counts.
If you’re building or upgrading a high-end PC gaming setup and want a monitor that can truly show it off, this LG UltraGear should be on your shortlist. Budget-focused buyers and those working mostly with static productivity apps may be better served by a more conventional flat or smaller display, but for dedicated gamers, it’s an impressive, well-reviewed choice.
