Our Verdict
Samsung CHG70
Acer Predator XB271HU Bmiprz
The Samsung CHG70 and the Acer Predator XB271HU Bmiprz have similar overall performance. They have different panel types, however, so each one is better than the other in different aspects. The Samsung CHG70 supports HDR and performs decently in that mode, and it also supports local dimming that makes blacks look deep in a dark room. The Samsung CHG70 has better reflection handling and a curve profile that some people like. The Acer Predator XB271HU, on the other hand, has better ergonomics so you can easily position it to your liking. The Acer has wider viewing angles due to its IPS panel, and thus it's easier to share your work.
