allan_intel,
It has been (5) months, we are waiting for your answer to which Intel processors for desktop has a 540Mhz CDCLK rate for the valid processor support of 4K (3840x2160@60Hz) mode using DP/1.2 set to SST or a configuration that will achieve the 4K (3840x2160@60Hz) on a UHD television. As I state above to robert_u, I can acheive WQHD 2560x1440@60Hz as the best resolution.
I feel Intel should be able to provide a rapid and simple explanation/instruction to create results in the real world of 4K (3840x2160@60Hz) on DP 1.2. We need enjoy the 4K resolution at 60Hz that we were promised and paid for.
We are choosing this route DP 1.2 (3840x2160@60Hz) because HDMI 2.0 at 3804x2160 only provides 30Hz bandwidth capacity at the best. 30Hz at 4K is just plain useless for action subject matter like a sports event or movie.
We await a response, please.
