Consensus

our Verdict

Professional reviewers were pleased with the LG 34GN850-B, recommending it for gaming. They praised its 160Hz refresh rate, native FreeSync support, and G-SYNC compatibility. If you need a 34-inch device with a better refresh rate, explore our LG 34GP950G-B review. Analysts clocked its input lag at a low 4.2 ms and found its rise-and-fall response time to be3.4 ms. Analysts at Digital Trends praised its UHD 3440 x 1440 resolutions, observing crisp text and graphics. If you need a more detailed 4K device, check out the 32-inch LG 32UL950-W. Testing revealed that this monitor hits the 441-nit level in HDR mode. Researchers reported a great color gamut, with a coverage of 99.9% of the sRGB color space, and they recommend the device for content creation. This monitor has two HDMI 2.0, although it doesn’t have a KVM switch, unlike the Gigabyte M34WQ. Product testers at Tech Radar praised its good viewing angles. However, they were not impressed by its low 960:1 contrast ratio, which resulted in sub-par blacks in dark environments.

The LG 34GN850-B has a better 160Hz refresh rate than the 144Hz of the Dell S3422DWG. Like most IPS panel-equipped monitors, the LG monitor also has wider viewing angles, starting to experience color washout horizontally after 40° compared to 35° for the Dell monitor. However, the VA panel-equipped Dell monitor offers better black levels and darkroom performance, featuring a much better contrast ratio of 2,725:1, which dwarfs the 960:1 of the LG display.
