Our Verdict

LG 27GL850-B/27GL83A-B

Dell S2721DGF

The Dell S2721DGF is a bit better overall than the LG 27GL850-B/27GL83A-B. The Dell has much better ergonomics, better build quality, and better reflection handling. On the other hand, the LG is more accurate out of the box, and for the two units we tested, the LG has better black uniformity, but this varies between units.
