Our Verdict

LG 27GP850-B/27GP83B-B

Dell Alienware AW2724DM

The LG 27GP850-B/27GP83B-B and the Dell Alienware AW2724DM are both good lower mid-range 1440p gaming monitors. They each have a max refresh rate of 180Hz, and motion handling is fantastic between each, but the LG has a backlight strobing feature to reduce persistence blur. The Dell gets brighter, so it's slightly better to use in bright rooms, but the LG is a bit better for use in dark rooms, or for watching HDR content, because it doesn't have a local dimming feature that worsens the contrast like on the Dell.
