    [SOLVED] El Capitan with 2560x1440 by HDMI (Ga-H97m-D3H / HD4400)

    Recently I managed to fix the 1440p graphics using HDMI with El Capitain.

    Yosemite has the same problem, so this solution probably could be used too. (maybe it works to 4k too, *not tested)

    I'm using a mobo Ga-H97m-D3H and an i3-4170 / HD4400

    Did two things:

    1. run mac-pixel-clock-patch

    https://github.com/Floris497/mac-pixel-clock-patch


    2. Patched AppleIntelFrameBufferCapri.kext according this method. I used Kext Utility to inject the patched kext.

    https://jonathansblog.co.uk/lg-34um95-osx-yosemite-resolution-bug

    (I'm not sure if step two is really necessary. I did it first. After a reboot nothing happened. Then applied the mac pixel patch, did a new reboot and find 2560x1440 resolution in pref panel > Displays! \o/



    UPDATE:

    a. I'm almost convinced step 2 isn't really necessary.
    b. Just did an automatic updated to 10.11.1. After reboot the screen resolution was lowered :( . Then I run the latest version of mac-pixel-clock-patch, did a new reboot and the find again 2560x1440 resolution in pref panel > Displays!

    is this patch works with any OS X version like 10.11.1 or require certain OS X version?

    i need to know before patching and don't want to get by running system to crash.

    Thanks

    This works on my HD4000 and LG Ultra monitor (2560x1080) but if the system goes to sleep upon waking the screen is only 1/4 of the original width and shifted. Anyone else have this problems?

    I upgraded to 10.11.1 reran the patch but still no luck. I just set computer sleep to never and will try to find another work around. Fortunately, it is now getting cold here so I don't mind a little house warming. :)
    Btw, without the patch, the video in 1920x1080 mode and the computer sleeps and everything works perfectly. This is on a ga-b75m-d3h motherboard with a i7-3770k processor (using hd-4000 video).

    Works on a Gigabyte H87N 10.11.2 built but for some reason setting the resolution @2560x1440 kills the wifi (BCM943225). It works fine on lower resolutions though.


    Can't figure out why.
