LG 34GN850-B is a 34-inch curved Nano IPS ultrawide monitor with a 3440 x 1440 resolution, up to 160Hz refresh rate, 1ms response time, and adaptive-sync support.
The monitor is praised as a very good gaming display with impressive image quality, fast gaming performance, and an immersive curved design. While noted as expensive, it is considered one of the best ultrawide options available.
The reviewer describes it as a remarkable piece of gear that excels in gaming requirements, including color representation and refresh speed, though they highlight the high price as a significant drawback that is difficult for many gamers to justify.
The monitor is lauded for being fast, feature-rich, and visually gorgeous. However, the verdict notes it is very expensive for a 34-inch screen and lacks features like USB-C and higher-tier HDR capabilities, making it a tough value proposition.
The reviewer calls it a superb ultrawide for both work and play, highlighting its sublime image quality and outstanding motion clarity. While not perfect due to inherent IPS limitations like contrast, it is recommended as the best ultrawide alternative despite potential availability issues.
