Current Issue: Acceleration only works until resolution of 2048x1152 pixels. Higher resolution (like internal display has 2560x1440) causes flickering.

Is this a knows bug of HD4400 on macOS HighSierra or can anyone help me to get it work?
(If EDID injections have to be done I would need help what exacly to do, do not understand it)

Activating Rehabmans patches for 96MB/128MB DVMT at config does not help, too.

These drivers are active now to get acceleration for 2048 pixels work:

- AppleALC v1.2.8
- Lilu v1.2.5
- WhateverGreen v1.2.0

Using this config.

I'm using it with 3840*1600, so it's possible.
If you want to use 128MB DVMT patch, make sure that you have also change the DVMT-prealloc in BIOS. (may need some BIOS-mod)
With 9MB patch it should be OK running below 3440*1440, as i have tested.

More infos in my last thread:

Because your problem is about flickering, i think it might be problem with pixel clock, or WhateverGreen doesn't work properly.
Try these commands and restart
sudo update_dyld_shared_cache -force
sudo kextcache -i /
Maybe you should try external monitor to see if it's flickering, too.

Many thanks for Your reply!



Unfortunately i can not set DVMT-Prealloc at my BIOS ...
but at your resolution 2560*1440, it don't need to change DVMT-Prealloc in my case. 9MB patch should work.

Ok, I will try to find this patch. Thanks!
