LG has just introduced something very new: the world's first IPS-based display with a super-low 1ms response time in its new UltraGear series gaming monitors.

The new LG UltraGear monitors come in both 27-inch and 37.5-inch varieties with different resolutions, aspect ratios, and refresh rates. They will use the same high-quality Nano IPS technology from LG with support for DCI-P3 color gamut as well as NVIDIA's G-Sync technology.
As for specs, we'll begin with LG's new UltraGear 27GL850 which uses a 27-inch IPS panel with a native 2560x1440 resolution, 16:9 aspect ratio, 144Hz refresh rate, and 1ms GtG response time.

LG's larger UltraGear 38GL950G is the one I want (and need in my life) with a larger 37.5-inch panel and an interesting 3840x1600 resolution, 21:5:9 aspect ratio, and slick 175Hz refresh rate (overclocked). The 38GL950G is DisplayHDR 400 certified while the 27GL850 supports HDR10.
LG hasn't said a word about pricing for both the UltraGear monitors, but the 27-inch model will have its pre-orders open on July 1 in the US and ships in Q3.
