Our Verdict

LG 27GL850-B/27GL83A-B

BenQ EX2780Q

The LG 27GL850-B/27GL83A-B is slightly better than the BenQ EX2780Q in mixed usage. Ergonomics are significantly better on the LG, as well as gradient performance. There's less color bleeding on the LG, but its black uniformity and contrast ratio are much worse than the BenQ.
