Our Verdict
HP OMEN 27
LG 27GL850-B/27GL83A-B
The LG 27GL850-B/27GL83A-B is much better than the HP OMEN 27 for most uses, but they offer very similar performance for gaming. The HP has better reflection handling and an optional black frame insertion feature, but the LG has slightly better motion handling overall, with slightly clearer motion. The LG supports HDR and has much better viewing angles, as well as slightly better ergonomics.
