Our Verdict
LG 34GN850-B
Acer Nitro XV340CK Pbmiipphzx
The Acer Nitro XV340CK Pbmiipphzx and the LG 34GN850-B have very similar performance overall. The Acer has much better ergonomics, better reflection handling, and a Black Frame Insertion feature. On the flip side, the LG has a slightly higher refresh rate, significantly faster response time, and it gets a lot brighter.
