    Hey,

    I recently got my Asus PB287Q (28") and hooked it up with my Macbook pro 13" from mid 2014, due to lack of research prior to the purchase, I was disappointed in finding out that the macbook only supported 4k@30hz, to my surprise.

    Still after searching around i managed to run the display on hiDPI mode in 1920x1080p@52hz (which is pretty nice, but too big..) and full native resolution 3840x2160@52hz (which is really too small for daily use) using SwitchResX.

    What I want is to be able to run hiDPI on larger resolutions than 1080p, hiDPI in 3008x1692 (6016x3384) would be perfect. I know there are limitations on the intel graphics, but shouldn't this be possible in the 50hz range?

    I tried some of the suggestions in this old thread, but to no avail.

    Any suggestions?

    Damnit, it seems i got the wrong cable.. (displayport 1.1) :oops:

    i just ordered a displayport 1.2 cable. To my knowledge the Macbook pro retina 13" (mid 2014) should be capable of running 4k@60hz with scaling options out of the box, could somebody confirm that?

    It's a bit vague on apple pages, it doesn't specify..

    my macbook has intel 5100 integrated graphics, that should support 4k@60hz

    - Apple's article on 4K support confirms that you need at least a 2015 model in order to run 4K 60Hz on a 13" rMBP:
    https://support.apple.com/en-ca/HT202856

    - Your machine uses the Intel U-processors. For those, Intel lists:

    Code:
    U-Processors: 3200 x 2000 @ 60 Hz, 3840 x 2160 @ 30 Hz
    Sorry.

    ah ok (canceling cable order, thx) but given that i can push it to run 3840x2160@52hz, shouldn't it be possible to activate other hidpi options above 1920x1080@~50hz?
