TechRadar Review: LG UltraGear Evo 39GX950B-B 5K2K Tandem OLED Monitor

Item: LG UltraGear Evo 39GX950B-B gaming monitor
Author: Savlume

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.

AI brief

From the source report

The reviewer found that the 39GX950B-B combines a 5K2K ultrawide picture with a 330Hz 1080p Dual Mode and reported strong HDR gaming results. It may be worth considering if immersive gaming and image detail matter more to you than the high reported starting price and the powerful GPU the native resolution may require.

Best suited for

Highlights

The 5120×2160 resolution provides a wider 21:9 view; the reviewer said it delivered sharp game detail and immersion.
