Summary
The LG UltraGear OLED 45GX950A-B is a 45-inch 5K2K (5120x2160) WOLED gaming monitor that has earned a strong following among ultrawide enthusiasts who want the best image quality and screen real estate available. Most owners describe the upgrade as transformative — especially those coming from 1440p ultrawides — praising the sharpness, HDR performance after calibration, and deeply immersive 800R curve. The catch is that this monitor genuinely demands a top-tier GPU: most users agree you need at least a 5080 or 5090 to push 5K2K at its native 165Hz in demanding AAA titles, which makes it an expensive ecosystem commitment. Sentiment is overwhelmingly positive among those with the right hardware, while users coming from QD-OLED panels sometimes find the WOLED colors underwhelming without tuning. A small but vocal subset report intermittent fan noise from their units, while others hear nothing at all — suggesting unit-to-unit variance.
