Our Verdict
Acer Nitro XV275K P3biipruzx
LG 27GR95UM-B
The LG 27GR95UM-B and the Acer Nitro XV275K P3biipruzx are both 4k gaming monitors with Mini LED backlighting. They have many of the same specs, but the Acer has a few advantages in terms of performance. The Acer has a better local dimming feature than the LG, with less blooming and black crush, and it has better motion handling too. The Acer also has some extra features, like a KVM switch and USB-C, making it the better choice for productivity. However, the LG is the better choice for console gaming at 60Hz thanks to its lower input lag at that refresh rate.
