Advantages
This LG UltraGear monitor combines a wide 21:9 curved OLED panel with a rapid 0.03 ms (GtG) response and 240 Hz refresh rate to reduce motion blur and input lag.

Eye comfort features verified by UL, multiple adaptive sync certifications (NVIDIA G-SYNC Compatible, VESA AdaptiveSync, AMD FreeSync Premium Pro) and integrated DTS Headphone:X plus dual 7W speakers complete the package for both PC and console use.
