What we like about this LG UltraGear 45GX900A-B monitor
Massive 45-inch OLED ultrawide
The LG 45GX900A-B uses a 44.5-inch 3440 x 1440 OLED panel with a 21:9 aspect ratio, giving it an extremely immersive feel. LG claims the 45-inch 21:9 format offers more screen area than a 49-inch 32:9 display, making it excellent for cinematic gaming.
240Hz OLED speed
With a 240Hz refresh rate and 0.03ms response time, this monitor is built for fast, fluid gameplay. OLED’s near-instant pixel response helps reduce ghosting and smearing, while the high refresh rate improves motion clarity and responsiveness.

Deep blacks and strong HDR presentation
OLED contrast is the big visual advantage here, with a claimed 1,500,000:1 contrast ratio, up to 98.5% DCI-P3 coverage, and VESA DisplayHDR True Black 400. Dark scenes should look especially rich, with precise shadow detail and excellent black levels.
HDMI 2.1, DisplayPort, and USB-C
Connectivity is strong, with HDMI 2.1, DisplayPort 1.4, and USB-C with 65W power delivery. FreeSync Premium Pro and G-Sync compatibility also make it flexible for AMD, NVIDIA, PC, and console setups.
Who should buy this OLED ultrawide monitor?
The LG 45GX900A-B is for gamers who want maximum immersion from an OLED ultrawide rather than a compact esports display. It is especially suited to racing games, RPGs, simulators, cinematic single-player titles, and high-end PC setups.
