Intel HD 630 Low Refresh Rate on 2560x1440

[Lurva]

Hi,

I am getting really low refresh rates with resolution 2560x1440 over HDMI on Sierra. On the same PC when using linux or windows it works without any problem. When I move the mouse frames are really missing there. Please help. This is the last thing I can't get over.. ah audio its not working, but well...

BTW: I patched the GPU using
https://www.tonymacx86.com/threads/...cpus-200-series-motherboards-in-macos.211743/

My MB: gigabyte z270m h3d
CPU: Intel Core i5 7600k - GPU Intel HD 630

Your display is connected to framebuffer@1. The connector-type there is <00 04 00 00> which is DP. You say it is actually an HDMI connector. You need to patch the framebuffer (ig-platform-id data) such that connector-type matches the physical connector <00 08 00 00>.

One quick question, where to edit these values? In config.plist I got only

<key>ig-platform-id</key>
<string>0x19120000</string>

It involves using KextsToPatch to patch the framebuffer kext.

The first external framebuffer connector data for 0x19120000 in AppleIntelSKL is (look for the data in a hex editor):
<01 05 09 00 00 04 00 00 87 01 00 00>

So to change it to HDMI, we replace with:
<01 05 09 00 00 08 00 00 87 01 00 00>

So... patch needed:
Comment: Port 0105 DP to HDMI
Name: AppleIntelSKLGraphicsFramebuffer
Find: <01 05 09 00 00 04 00 00 87 01 00 00>
Replace: <01 05 09 00 00 08 00 00 87 01 00 00>

Use a plist editor to make the entry in KextsToPatch.

Installing the Pixel Clock Patch should also enable the full functionality of your HDMI port, which is a little easier to do. @RehabMan's approach is the correct one though (and it should survive all upcoming updates, in contrast to the Pixel Clock Patch).

Thank you! It is working, I am so glad. Keep up good work!
