    HD 530 / i7-6700K: 4k60p won't work at HDMI 2.0 on Windows




      Answers (N/A if not applicable)


      Provide a detailed description of the issue

      I am not able to get my dual Monitor Setup to work properly.
      The 1st Monitor is plugged into the  DP1.2

      The 2nd Monitor is plugged into the HDMI 2.0.


      DP 1.2 is operating fine 4k60p

      HDMI 2.0 is only working until 4k30p, everything above 30p will not be displayed at the 2nd LG Monitor.


      I've used the following Drivers:

      Windows OEM Intel Driver: No Success

      Newest Intel HD Driver: No Success

      Newest Gigabyte Intel HD Drive: No Success


      The Megachips HDMI Firmware is up to date @ Version v1.42


      HDMI UHD Deepcolor is activated on the HDMI LG Monitor, otherwise the Intel Drive won't Show 4k60p


      I've testet also on a Ubuntu 15.10 Live Disk.

      Both Monitors are working at 4k60p!
