I am just making the jump to 4k. I have a boxnuc6cayh that has all firmware and bios updates done and has Escalades community build on it. I also just purchased a new Denon avr-x2300w receiver and a a Vizio M65-E0. Inside the Kodi gui I am only getting the option of 4k 3840X2160 @ 30hz when I run xrandr I do not get the 60 option either. 3840x2160 30.00*+ 24.00 29.97 23.98. I have tried going from the nuc straight to the TV and through the receiver as well. Full UHD color is turned on inside the Vizio TV and I have brand new HDMI cables from Sams Club.
Any ideas of how I can get the gui to work at 60hz or is this normally not possible unless actually playing video? Any ideas are greatly appreciated.
