Our take
The LG UltraGear 27GX790AB offers the same blistering 480Hz refresh rate as the 27GX790A-B but at a lower price. Motion clarity is phenomenal, and the 0.03ms response time keeps everything crisp. However, the specs list a contrast ratio of 1000:1, which is contradictory for OLED; I suspect it may be a misprint or refers to a different metric. Brightness at 250 nits is modest. The monitor includes USB 3.0 ports and HDMI 2.1, which is nice. The stand likely offers limited adjustments. For $700, it's a compelling option if the contrast ratio is an error, but verify before buying.
