45-inch 5K2K OLED gaming monitor

The LG UltraGear 45GX950A-B is a 45-inch curved OLED display built for gamers who want ultra-wide immersion and high pixel density. Its 5120 x 2160 resolution and 21:9 aspect ratio deliver a 5K2K canvas that suits both competitive play and content creation. The 800R curvature wraps the image around the viewer for a more enveloping field of view. Adaptive sync support covers FreeSync Premium Pro and G-Sync Compatible for tear-free motion.

Dual-mode resolution and refresh headroom

In its native 5K2K mode the panel runs at 165Hz, providing sharp detail for strategy titles and desktop work. A dual-mode option drops the output to Full HD at 330Hz, giving esports players a higher frame-rate ceiling when speed matters more than resolution. The 0.03ms grey-to-grey response time keeps motion clear at either setting. Brightness peaks at 1300 cd/m2 with a 1,500,000:1 contrast ratio for deep blacks and vivid highlights.

DisplayPort 2.1 and HDMI 2.1 connectivity limits

The single DisplayPort 2.1 input and two HDMI 2.1 ports provide the bandwidth needed for 5K2K at 165Hz or Full HD at 330Hz with HDR10. USB-C delivers up to 90W power delivery for a connected laptop or peripheral. The 100 x 100mm VESA mount allows arm or wall installation if the included height, pivot and swivel stand is not used. Buyers who need more than one DisplayPort 2.1 lane or a higher sustained full-screen brightness level will find the interface and panel specs fixed at these values.

Questions about this item

Will my older graphics card with HDMI 2.0 still drive the 5120 x 2160 panel at 165 Hz?

The monitor requires HDMI 2.1 or DisplayPort 2.1 for full 5K2K at 165 Hz; HDMI 2.0 bandwidth is insufficient for that resolution and refresh rate.

How do I verify the 0.03 ms response time and 165 Hz refresh are active after setup?

Enable the on-screen frame-rate counter, set the OS to 165 Hz, and run a motion-blur test pattern; smooth UFO trails confirm the panel is operating at spec.

Does the box include the DisplayPort 2.1 cable needed for 5K2K 165 Hz, or must I buy it separately?

The package supplies an HDMI 2.1 cable and a USB-C cable; a DisplayPort 2.1 cable is not included and must be purchased separately.
