    I'm not having any luck getting 3840x2160 at 60hz.. 30hz no problem.. and 1080p at 120hz no problem. Ive got the alienware 15 with the 980m. Games look fantastic at 1080p @ 120hz but I'd love to see them at 4k res at 60hz, the 30hz just ruins the experience yet the image quality is beautiful. If you are able.. please let me know the cables your using and driver version.. I'm using a belkin mini display port adapter and hdmi 2.0 cable both rated at 4k/60hz. Driver ver. 9.18

    A few things you should make sure of before you can actually can run 4K 60fps on an external tv/monitor.

    1st of all your laptop needs to have HDMI 2.0 support and/or Display Port 1.2 to be able to run 4K 60fps video.
    2nd of all, the cable you are using needs to be HDMI 2.0 and or Display Port 1.2
    3rd of all, your monitor/TV needs to have HDMI 2.0 or Display port 1.2.
    (4th your GPU needs to support 4K 60fps, which it does)

    Now since we are talking about TV's and not monitors, your issue is most likely on the 3rd step. Quite some modern TV's do have support for crazy refresh rates such as 400hz and even more, but they cannot accept video input of 4K 60fps, because they lack the 3rd point I mentioned.

    Instead of playing a high refresh rate video, what TV's often do is, Frame Interpolation. Meaning they look at a Frame, they look at the next frame, and they create generated frame to put inbetween, which is just an algorithm, that is not always perfect, especially when there is a lot of movements in the source video, and some TV's even put 3 generated frames inbetween 2 frames, achieving this, marketed high refresh rates.
