TechRadar Review: LG UltraGear Evo 39GX950B-B 5K2K Tandem OLED Monitor
TechRadar reviewed the LG UltraGear Evo 39GX950B-B, a 39-inch 5K2K (5120x2160) ultrawide gaming monitor built with a fourth-generation tandem OLED panel and a 165Hz native refresh rate. The reviewer praised its exceptional pixel density, vibrant HDR highlights reaching up to 1,500 nits, and a versatile 1080p 330Hz Dual Mode option. However, the display requires high-end PC hardware to maintain smooth frame rates, runs warm during extended sessions, and faces steep competition at its $1,799.99 list price.
