Market Context

Compared to the same brand’s similar models: The LG 34GP950G-B(This review) has a higher 180Hz refresh rate compared to the 160Hz of the LG 34GN850-B. These two monitors have a similar 34-inch IPS screen size but differ in the supported variable refresh rate (VRR) tech. While the LG 34GP950G-B natively supports G-SYNC, the LG 34GN850-B natively supports FreeSync, which isn’t that different than the Nixeus EDG 34.

Featuring a similar 34-inch curved screen, IPS panel type, and HDR10 tech, the LG 34GP950G-B, and the LG 34GP83A-B are very similar. However, the LG 34GP950G-B has a local dimming feature, which is not present in the LG 34GP83A-B. The two monitors support different anti-tearing technologies, with the LG 34GP950G-B having native NVIDIA G-SYNC, while the LG 34GP83A-B is compatible with G-SYNC. Although, neither of them uses Adaptive Sync, as you’ll find in the MSI Optix G272.

Compared to other brand’s similar models: Being LED-backlit, the LG 34GP950G-B gets brighter in HDR mode (656-nit peak brightness), than the QD-OLED Dell Alienware AW3423DW, which has a peak brightness of 484 nits. On the other hand, the Dell monitor has a better 0.4 ms rise-and-fall response time than the 3.9 ms of the LG device. In terms of darkroom performance, the Dell monitor provides deeper black levels, featuring an infinite contrast ratio, compared to the LG’s 836:1.

What’s New In This Model Year Vs Previous Model Year: The LG 34GP950G-B is very similar to its predecessor, the LG 34GK950F-B, with both monitors having a 34-inch 3440 x 1440 screen and an IPS panel. The newer gaming monitor goes one better, featuring HDR10 tech, which is missing on the older model.

Digital Trends product testers hailed its wide viewing angles, commenting that the only observed color washout after 43° horizontally.
