Design and Build
The LG 45-inch UltraGear presents a commanding presence with its borderless design on three sides, emphasizing the expansive OLED panel. The monitor’s dimensions of 39.1 inches wide, 25.9 inches high, and 13.2 inches deep underscore its substantial footprint, requiring a deep desk and ample viewing distance for comfortable use. The 800R curvature is described as dramatic and steep, engineered to wrap around the user’s field of view and create a sense of being surrounded by the gameplay. The screen finish is matte, which helps reduce glare and distractions during intense gaming sessions. The stand offers ergonomic adjustments, though the specific range of tilt, swivel, and height adjustment is not listed by the manufacturer. The overall build quality aligns with LG’s premium monitor lineup, designed for a permanent, optimized battlestation setup rather than portability.
Performance and Features
Visual Performance
This is where the OLED panel shines. With a VESA DisplayHDR True Black 400 certification, the monitor delivers deep, rich black levels and impeccable detail in dark scenes, a critical advantage in atmospheric games. The near-infinite 1,500,000:1 contrast ratio and 98.5% DCI-P3 color gamut coverage contribute to a lifelike and stunning visual experience. The 3440 x 1440 WQHD resolution on a 45-inch screen provides a high pixel density for sharp imagery, though the pixel pitch is listed as 0.30mm. A brightness of 275 nits is specified, which meets the requirements for the True Black 400 standard.
Gaming Performance
The combination of a 240Hz refresh rate and a 0.03ms gray-to-gray response time is engineered to eliminate lag, ghosting, and motion blur. This ultra-fast performance is aimed at giving competitive gamers a tangible edge, allowing for quicker reactions. The monitor supports both AMD FreeSync Premium Pro and is NVIDIA G-SYNC Compatible, ensuring tear-free and smooth gameplay across a wide range of graphics cards. Additional gaming-centric features listed include a Black Stabilizer to enhance visibility in dark areas and a Color Weakness mode for accessibility.
Connectivity and Audio
Connectivity is comprehensive for a high-end gaming setup. The monitor includes two HDMI 2.1 ports, a DisplayPort 1.4 input, and a USB-C port, facilitating connections to modern PCs, consoles, and laptops. Three USB ports are available for peripherals. Built-in speakers are included, offering a basic audio solution, though serious gamers will likely prefer dedicated headphones or external speakers. The bundle notably includes two Deco Gear 4K HDMI 2.0 cables with pure copper conductors, adding immediate value.
Setup, Support and Ownership
Warranty and Protection
The product comes with a limited 2-year manufacturer’s warranty. A key aspect of this specific bundle is the inclusion of the Deco Gear CPS Exclusive 26-Month Premium Extended Service Protection Plan.

This extended coverage directly addresses a potential drawback and adds significant peace of mind.
Software Bundle
The bundle includes the Tech Smart USA Elite Suite 18 Standard Editing Software Bundle. The specific applications and features within this suite are not detailed in the provided data, but it represents an added software value on top of the hardware purchase.

Who Should Buy It (and Who Should Skip It)
The LGElectronics E90LG45GS95QEB is an ideal choice for dedicated PC gamers and enthusiasts who have the desk space and hardware to drive its high refresh rate and resolution. It is perfect for those who value immersion above all else, wanting to be surrounded by the game world with the best possible contrast and motion clarity. The included extended protection plan makes it a smarter buy for users worried about OLED longevity. It also suits content consumers who enjoy ultrawide movies and HDR content.
This monitor is not recommended for gamers on a tight budget, those with small desks, or users primarily focused on productivity with lots of static screen elements (like spreadsheets or coding IDEs) who are concerned about potential OLED burn-in despite the coverage. It is also overkill for casual gamers or those whose graphics cards cannot consistently drive high frame rates at 3440×1440.
Final Verdict
The LG 45-inch UltraGear OLED gaming monitor is a specialized tool for a specific audience. It successfully merges the unparalleled visual performance of OLED—with its perfect blacks and high contrast—with the raw speed demanded by competitive gaming. The 800R curve on such a large screen creates a uniquely immersive experience that is difficult to replicate with flat or less curved displays. The bundle’s thoughtful inclusion of extended protection for accidents and burn-in directly mitigates one of the few remaining drawbacks of OLED technology for desktop use.
While its size and price are significant considerations, for the gamer who has the space, budget, and desire for a truly enveloping and responsive visual experience, this monitor stands out. It is less of a general-purpose display and more of a dedicated centerpiece for a high-end gaming rig. When evaluating the best ultra-wide monitors or curved monitors, this model’s combination of OLED, extreme refresh rate, and bundled protection makes it a compelling, if premium, option.
FAQs
Does this monitor have a risk of screen burn-in?
Yes, as an OLED display, it carries the inherent risk of image retention or burn-in if static elements are displayed for prolonged periods. However, this specific bundle includes a 26-month extended protection plan that explicitly covers burn-in, which is a significant benefit and reduces the long-term risk for the owner.
Is the 240Hz refresh rate noticeable over 144Hz?
For fast-paced competitive gaming titles like first-person shooters or racing games, the jump from 144Hz to 240Hz can provide a marginal improvement in motion smoothness and reduced perceived blur. The difference is more subtle than moving from 60Hz to 144Hz, but high-level players may appreciate the extra headroom for responsiveness.
What graphics card do I need to use this monitor effectively?
To fully utilize the 3440×1440 resolution at high frame rates approaching 240Hz in modern games, a high-end graphics card such as an NVIDIA RTX 4080/4090 or AMD Radeon RX 7900 XTX is recommended. For less demanding esports titles, a powerful mid-range card may suffice.
What is included in the box with the monitor?
The bundle includes the LG 45″ UltraGear monitor, a power cable, a DisplayPort cable, an HDMI cable, the standard 2-year limited protection, the 26-month CPS extended service plan, two Deco Gear 4K HDMI 2.0 cables, and a download for the Tech Smart USA Elite Suite 18 software bundle.
