CoreDisplay: Add hash for 16A323 on intelHD 4600

[grigorovich]

I checked on intel HD4600 2560x1080 (21:9). Works fine. macOS X 10.12, 16A323 Just add hash in CoreDisplay-patcher at oToolCoreDisplayPatched:

oToolCoreDisplayUnpatched=( ... aa7607dd72a2a4ca70ce094a2fc39cce '10.12 16A323' 1 # 10.12 )

I tried this doesn;t work correctly with Nvdia Titan X. My 4k screen just flashes now.. so I had to plug a monitor into DVI to get mac to the desktop and unplugg my 4k screen from hdmi

[Floris497]

Will look at it after work.. sorry guys past months i had verry little time to look into this thing

[svickory]

Thanks Floris, I really do not want to reload macos :-)

[Floris497]

Someone pushed an update not long ago, can you try that one?

[Floris497]

Make sure you first undo the current patch :)

[svickory]

Floris ive tried oToolCoreDisplayUnpatched=( ... aa7607dd72a2a4ca70ce094a2fc39cce '10.12 16A323' 1 # 10.12

what happen is I have a 4k monitor in hdmi and a normal monitor in dvi the 4k monitor doesnt even come on now. but the monitor in DVI Flashes UNTIL i unplug the 4k monitor from the hdmi port on my Titan X

Also whats the easiest way to undo the patch ?

[Floris497]

Something like Patch.command unpatch :)

[svickory]

i dont see a patch.command unpatch

[Floris497]

There is non, i meant the same command file you patched with :)

[svickory]

I just tried it reverted.. i tried the patch again same issues. dvi monitor flashes . hdmi monitor not turning on. also using the new nvidia drivers 367.15.10.05F01

[Floris497]

Should not interfere with the nvidia drivers.. unfortunately i don't have a working nvidia card at the moment..

[svickory]

i hope I dont have to reinstall.. its a real pain :-)

[Floris497]

As long as you did nit overwrite.. the script warns you not to :) most of the time you don't need to reinstall

[svickory]

I have reloaded macos 10.12 . same issue something is not right with this patch.

[Floris497]

Let me see when i get home :)

[grigorovich]

Just add hash and patch works fine on Intel HD 4600> (DualDVI-D<>HDMI) > monitor 2560x1080

[Floris497]

Maybe it's something with the nvidia driver that doesn't play well.. remember only to use the IOKit patch if you want to enable HDMI2.0

[grigorovich]

On 10.12 16A323 i used CoreDisplay patch for intelHD only. For Nvidia i didnt tested. Anyway coredisplay patch works fine for me on macbook air A1466 core i7 and hackintosh core i7 4790 - ihd5000 and ihd4600. Thanks for that patch.

[Floris497]

*coredisplay sorry.. IOKit is the old one.. ignore i said iokit

[svickory]

i thought i had it working.. but its not.. What I am trying to get working is 3860*2160 at 60Hz . I have SwitcherX also..

[Floris497]

I assume you mean 3840x2160@60Hz you want this to be possible over HDMI (for 60Hz this needs HDMI2.0) HDMI2.0 is not enabled because a limit in CoreDisplay (IOKit before) is limiting this for all graphics adapters. It looks like other people have succes with this patch although I've not heard any succes with Nvidia cards on HDMI2.0 on MacOS 10.12. but also have not heard of people not getting it to work.. Could you post the MD5's you have right now? please look in the readme how to generate them. I'll update my laptop now so I can see if they are correct. hope this helps you :)

floris yes i meant 3840x2160@60Hz

[Floris497]

So it looks like the patch did not even patch.. or did you undo the patch already? Since other people have success I need to investigate wha't going on. Could you try to patch again. now using the OS X drivers (Do they support Titan X?)

[svickory]

I did unpatch. OS X Drivers dont support Titan X . I have to install the nvidia Drivers .

[Floris497]

Hm.. Will take some time, I'll try to look into it this weekend or Friday.. can't promise anything. Your display does not support DisplayPort?

[svickory]

No I am using a Samsung 4k TV.. (The patched worked perfectly when i was running 10.11) also I just ran the patch . here is the outpit

update. so I removed SwitcherX before I patched. I did the patched then reboot . everything working Install SwitcherX . so I see 3840x2160@60Hz Soon as I choose its my 4k monitor goes blank and my 2nd monitor connected via DVI Starts Blinking... so I unplug the hdmi plug from my video card remove the patch reboot everything working again at 30Hz :-(

[svickory]

any updates?

[Floris497]

Nope.. will have to look at it later.. don't have much time :/

[qvt]

Same problem here. 4k Samsung remains blank after patching 16a323 CoreDisplay driver, even at 30Hz. It used to work with my MacMini 2010 with integrated IntelHD card on El Capitan after I patched the IOKit driver.

[Floris497]

Could you try the following (I'm not sure if it will work, but I have no way of testing it..): 1: unpatch CoreDisplay 2: uninstall all Switchresx 3: reboot Mac 4: repatch 5: reboot 6: set Switchresx 7: reboot to get resolutions to work.

Step 5 might not be necessary, maybe it's all not even working..

[qvt]

I never had luck with SwitchResX, so I finally settled with 3140x2160@30Hz. This worked out of the box on my MacMini Late 2012, just with (i) your pixel clock patch and (ii) a Club CAC-1153 MiniDisplayPort 1.2 to HDMI 1.4 3D cable. The patch worked on a clean system until El Capitan. Do you think I should give SwitchResX another chance?

[Floris497]

60Hz over HDMI1.4? Don't think that is possible?
