Our Verdict
AOC CU34G2X
LG 34GN850-B
The LG 34GN850-B and the AOC CU34G2X are both great gaming monitors with different panel types. The LG has an IPS panel with wider viewing angles, while the AOC has a VA panel with higher contrast. Motion looks much better on the LG because it has a quicker response time, and it doesn't have black smearing like on the AOC. The LG also gets much brighter, so it does a better job at fighting glare. If ergonomics are important to you, the AOC offers swivel adjustments, which the LG doesn't.
