Updated 3/9/18 with release date and expected price.
LG are set to release a new 34″ 3440 x 1440 resolution ultrawide (21:9 aspect ratio) monitor in there range, the 34GK950F (not to be confused with the 34GK950G which has G-sync). This screen is based on the latest LG.Display ‘Nano IPS’ panel technology which has enhanced phosphors on the backlight to extend the colour gamut. A flicker-free W-LED backlight is used with a ‘KSF phosphor’ layer (K2SiF6 doped with Mn4, for the chemically minded) to achieve 98% DCI-P3 (~135% sRGB).
One of the key areas of interest is the 144Hz native refresh rate support offered here which is combined with Adaptive Sync / AMD FreeSync 2 capability over both DisplayPort and HDMI connections. There is also an added strobed backlight for motion blur reduction benefits and a 1ms MPRT spec.
I other specs the 34″ panel offers a 5ms G2G response time, 1000:1 contrast ratio, 400 cd/m2 brightness, 178/178 viewing angles and 10-bit colour depth (8-bit+FRC). The stand offers tilt, height and swivel adjustments. There are DisplayPort 1.4, HDMI 2.0, 2x USB 3.0 and a headphone connection offered.
updated 3/9/18: expected release date is Q4 2018 with a current RRP of €1199 in Europe.
