Hi Toleda,

Sorry for my late response. I removed the patches for port 6 (thats where the LG display is connected) and now there is no glitch but the resolution of the display is only 1920x1080 instead of the 2560x1080. If I reapply the patch, after sleep I can get the 2560x1080 resolution.

I check the website of my motherboard and it states the following:

""1 x DVI-D port, supporting a maximum resolution of 1920x1200@60Hz"

Could be the root of the problem?

Currently applied patches is attached.

Thank you for your support!

If that's a hardware limitation then I don't know why it's working in the native resolution if I apply your patch. (Of course, there will be glitch for the first time, but If I sleep the computer then I wake it up, it works properly in 2560x1080)

I will apply the "Mac Pixel Clock patch" since I think the native resolution is over the 165 Mhz limit.

I will reply how it went

Hi Toleda

how can I change the memory size of HD4600 framebuffer to have 4K output on Display Port? My mobo is capable of 4K via DP and I am running Mavericks.

I found this post, but it seems to be only for 10.10+ as i do not find the data in my 10.9.5 kext binary:

Unfortunately, didn't solve the issue. I applied the patch again for the DVI, and it works as before.

I think, I will try to inject the EDID of the LG display, after that I will run out of ideas.

I've been trying to get 3 displays working for a while now on my Asus Z97-A with HDMI+DVI+DP. The ports works fine individually or in pairs, but with all three displays connected, I get a kernel panic during boot.

So. A quick question, before I'm wasting any more time on trying to solve this:

Does OS X (El Capitain) on HD4600 chipset support 3 displays at all?
(Post #70 (page 7) in this thread claims "OS X/HD4000 supports 1 or 2 displays." on a question on three displays)

If no, I shall stop trying... If yes, I shall continue!
Thanks

HD4600 supports 3 displays
HD3000/HD4000 supports 2 displays
