What we like about this LG UltraGear 45GX950A-B monitor
5K2K ultrawide OLED resolution
The LG UltraGear 45GX950A-B combines a massive 44.5-inch OLED panel with a 5120 × 2160 resolution and 21:9 aspect ratio. This 5K2K format provides considerably more horizontal workspace than conventional 4K while retaining the same 2160-pixel vertical resolution, making it equally useful for immersive gaming, content creation, large timelines, and multi-window productivity.
125 PPI with improved text clarity
The higher resolution gives the display a pixel density of roughly 125 PPI, a significant improvement over earlier 45-inch ultrawide OLED monitors with lower vertical and horizontal resolutions. LG also uses an updated subpixel structure intended to reduce color fringing around text, making the panel substantially more practical for productivity, coding, browsing, and creative applications as well as gaming.

Dual Mode with 165Hz and 330Hz operation
Dual Mode gives the monitor two very different performance profiles. At its native 5120 × 2160 resolution it can operate at up to 165Hz for visually demanding games, while switching to Wide Full HD allows the refresh rate to rise as high as 330Hz for competitive shooters, MOBAs, racing games, and other titles where maximum responsiveness matters more than resolution.
0.03ms OLED response time
LG rates the panel for a 0.03ms gray-to-gray response time. OLED pixels transition extremely quickly compared with conventional LCD technology, helping reduce ghosting and motion smearing during fast camera movements and high-refresh gameplay.
Deep blacks and strong HDR performance
Each OLED pixel produces its own light and can switch off independently, allowing the monitor to achieve extremely deep blacks without relying on a local-dimming backlight. LG quotes a 1,500,000:1 contrast ratio, DisplayHDR True Black 400 certification, HDR10 support, and peak highlights reaching up to 1,300 nits under appropriate conditions.
98.5% DCI-P3 color coverage
The panel is specified to cover up to 98.5% of the DCI-P3 color gamut. That gives it the wide color range required for vivid HDR gaming and also provides useful coverage for video production and other color-sensitive creative work.
DisplayPort 2.1, HDMI 2.1 and 90W USB-C
Connectivity is unusually comprehensive for a gaming monitor. DisplayPort 2.1 provides a modern high-bandwidth PC connection, while two HDMI 2.1 ports support contemporary consoles and other high-resolution sources. USB-C adds both display connectivity and up to 90W of power delivery, allowing many laptops to run from a single cable.
FreeSync Premium Pro and G-SYNC compatibility
AMD FreeSync Premium Pro and NVIDIA G-SYNC compatibility allow the panel’s refresh rate to track the GPU’s frame output dynamically. This reduces tearing and minimizes the judder associated with mismatched frame and refresh rates, which is especially useful when demanding 5K2K games fluctuate substantially in performance.
Who should buy this 4K ultrawide monitor deal?
The LG UltraGear 45GX950A-B is aimed at enthusiasts who want one display to handle cinematic gaming, competitive gaming, and serious productivity without moving to a multi-monitor setup. Its native 5120×2160 resolution makes it particularly attractive to users who found previous large ultrawide OLED monitors too low in pixel density for desktop work. The 125 PPI figure is much closer to what users expect from a high-resolution productivity display, making text, interface elements, and fine details noticeably sharper. Running modern games at 5120 × 2160 and 165Hz is extremely demanding, so the monitor makes the most sense when paired with a high-end GPU. Competitive players can instead use the 330Hz lower-resolution mode when responsiveness takes priority over image detail.
