Our Verdict
Acer Predator XB271HU Bmiprz
LG 27GL850-B/27GL83A-B
The LG 27GL850-B/27GL83A-B is better than the Acer Predator XB271HU Bmiprz. The LG supports HDR and can handle reflections better, which is important when there are a few lights in your room. The Acer, on the other hand, has a black frame insertion feature that helps make the image look crisper.
