Right now I have a monitor that has a Displyport input and an HDMI input. The HDMI is only 1.2 so it only supports 4k @ 24Hz. I'm going to get the Xbox One S which plays games at 4k and I want them to play at 60 or 30 Hz. I need an adapter from HDMI to Dp, and I'm having trouble finding a cable to do that. Does anyone know what cable would solve this problem?
