Acer XR341CK Gaming Monitor Official Information
"Spec wise both versions offer a 34" ultra-wide screen size with 21:9 aspect ratio and a curved screen format. They are based on IPS panel technology and given we are only aware of LG.Display producing IPS-type panels in this sector, they are likely to be AH-IPS from LG.Display. The screens have a 3440 x 1440 resolution and support refresh rates up to 75Hz. Some people may be disappointed that there is not support for 120 - 144Hz but that is not possible at the moment from current IPS-type panels of this size and format. At least there is a bit of a boost beyond 60Hz potentially here which is something. The support for dynamic refresh rates via the G-sync or FreeSync technologies will help users cope with the demand of the high resolution as well here and are certainly welcome.
In other specs there is a 4ms G2G response time, 1000:1 contrast ratio (100 million:1 DCR), 300 cd/m2 brightness and 172/178 viewing angles (owing to the curved nature). They are listed as having an 8-bit+FRC panel which implies a 1.07b colour depth, although elsewhere in the spec it also lists 16.7m. A standard gamut W-LED backlight offers a 72% NTSC coverage / sRGB gamut.
The XR341CK (FreeSync version) will offer HDMI 2.0 (MHL), DisplayPort, Mini DP and DP out connections, along with a 4 port USB 3.0 hub. It will support daisy chaining via the DP out port and also PiP and PbP functions."

Both NV and AMD are taking forever it seems to roll-out new high quality FreeSync/GSync monitors.
