No such setting...it is 4K 60fps connected to the LG...looks like a NVIDIA & LG are doing something "non-standard" with their HDMI connection...might need a firmware update to keep up with them? LG & NVIDIA have some sort of special relationship...LG just announced an update to support the G-Sync ability of the NVIDIA card. 2 of the biggest vendors in the market...needs to be supported.
