    iris 540 of i5 6260U cannot support lg 31mu97 with 4096x2160p at 60Hz


      I have

      intel nuc 6i5syk with i5 6260u

      mini DP - mini DP and mini DP - DP cables

      LG 31mu97 monitor which is 4096 x 2160p.


      after installing win10 x 64 the monitor work well with 3840 x 2160 at 64Hz


      but after installing iris 540 driver, the monitor shows no signal.


      If I turn off monitor's DP1.2 option, the monitor can work with 4096 x 2160 at 30Hz with self-setting resolution.


      How can I get it work with 4096 x 2160 at 60 Hz? I tried several different versions driver which does not solve the problem.


      Thank you
