Who it fits
Good fit for
This monitor suits PC gamers who prioritize visual fidelity and immersion. The 5K2K resolution offers sharp text and detailed images, ideal for story-driven adventures. The dual-mode feature benefits competitive FPS players who need high refresh rates. It also works well for productivity tasks due to the wide aspect ratio and clear subpixel layout.

People who prefer smaller screens for desk setups will find the 45-inch size too large.
Verdict: The LG 45GX950A-B delivers exceptional clarity and speed for ultrawide gaming. Its dual-mode flexibility and OLED quality make it a strong choice for immersive experiences.

Before You Buy This Monitor
Before you buy, check your PC’s connectivity. This monitor requires DisplayPort 2.1 for its highest performance. You also need a GPU that supports the necessary bandwidth to drive the 5120 x 2160 resolution at 165Hz. If you use a console, HDMI 2.1 ports are present, but verify your device’s output limits. The Dual Mode feature allows switching to 330Hz at a lower resolution. This requires manual input via a hotkey, so plan your workflow accordingly. OLED panels benefit from regular use to prevent image retention. Ensure your system has adequate ventilation, as the 45-inch screen generates heat. This monitor sits alongside other large OLEDs in our 1 options. Unlike smaller ultrawides, its 21:9 aspect ratio demands a deep desk. The 125 PPI offers sharp text, making it suitable for mixed work and play. However, its size and power draw are significant considerations. You must verify your desk space can handle its 39-inch width and 30.9-pound weight. Proper cable management is essential given the multiple high-speed ports.

- Check desk depth for the 13.5-inch stand.
