    Just an update in case anyone runs into a similar problem. I purchased a Club3d displayport to HDMI adapter and can run 2k and 4k 60hz resolution. Starcraft 2 looks great.

    Thanks all.

    It doesn't work that way. There's no physical video output connection to the 970M at all. If you do manage to disable the Intel device there's no output left to use. You either use the 4600 or have a black screen.

    That depends on the model, obviously.

    Hi, I know the thread is a bit old...

    I got the same adapter and I have exactly the same PC setup, 970M with Intel HD4600, but I can't get 4k@60hz, my TV is Sharp and it does have an HDMi 2.0 connection.

    Did u do anything particular to make it work?

    The way Optimus (and other hybrid graphics) work is by passing the discrete GPU signal through the integrated GPU's interface. So you're still limited by everything the integrated GPU can do, since there's no actual direct connection between the discrete GPU and the outputs. The only way to get it to work is with an upconverting adapter like the Club3D one that the OP us using. Otherwise you're stuck at 30Hz.

    Thanks for the reply pitabread, as I wrote in my post I already have the adapter and that's the problem, is not working.

    I was curious to know if the OP run into issues the first time he tried it.

    My TV has 4 HDMI ports, with 2 of them being HDMI 2.0, so you'll need to make sure you're plugged in to the correct port. Also, for me I had to go into the TV settings and set "HDMI Enhanced" on. You might have some similar setting you need to enable from the TV. Try researching your specific model and 4k 60hz input.

    Here's my setup.

    Displayport -> Club 3d adapter -> HDMI 2.0 cable -> HDMI 2.0 port in my TV.

    In the intel settings under Display I hit Custom Resolutions, set the resolutions and refresh rate, I think there was a timing standard option set to CVT-RB, and that was it. Are you getting an error message?

    Ok thanks! no error message, just a black screen if I choose "maintain display scaling"(the other option works).

    I already updated the adapter firmware more than once, bought a new cable, setup custom resolution like you did, check my TV setup and had an extensive email exchange with Club3D but no solution yet.

    At least I had another confirmation from you (like many others), that the intel HD4600 support 4k@60hz.

    I guess my laptop is at fault....

    I just have to keep researching and understand why it doesn't work for me.
