Hello and TY for your reply! At this point HDMI is not really an issue for me. Undocked i have HDMI working and DP is now working too with my patch. I tried to connect a DVI and DP cable while being docked at the backside of my docking. The screen flashes but i am not able to find the changes IOregistryExplorer. I did find the onboard ports though: Framebuffer 0: Port 0 APPL,DisplayPipe 00 00 00 00 av-signal-type 00 00 00 00 connector-type 02 00 00 00 Framebuffer 1: Port 5 HDMI onboard AAPL,DisplayPipe: 02 00 00 00 av-signal-type: 02 00 00 00 Connector-type: 00 04 00 00 Framebuffer 2: Port 6 miniDP onboard APPL,DisplayPipe 01 00 00 00 av-signal-type: 02 00 00 00 connector-type: 00 04 00 00 At my work i use linux until my hackintosh is ready and i remember i had the same problem before MST(Multi Stream Transport) was added to the kernel. I think this problem is somehow related. Unfortunately the laptop's onboard DP get's disabled as soon as the laptop is being docked, therefore cannot use the onboard DP. I still hope you can find some time to help us, i have no idea what to do next. ( add additional FB's, change pipes, attributes etc.)

I have added port 7. I got this idea when i stumbled across an old post somewhere: So i took all the needed bytes from platform id: 0x0d260007(because is has an extra HDMI port) and tried to fit them in 0x0a26006.

DP was't working before. docked: nothing works yet(except USB etc). TODO: - I still like to use the docking station, i will keep trying. - I removed all AppleIntelFramebufferAzul patches from the e7440 bootpack to make sure i have no conflicts. - Create a clover patch to survive Kextoverrides after upgrades.

Hello All, I did some testing but i was unable to solve my issue. I have patched my AppleIntelFramebufferAzul.kext using Pike R. Alpha's script.

While connecting i can see that my laptop's screen turns black for a second but the external screen stay black with no signal. I think the problem is: Somehow i need to change the port number to a number which matches an external DVI port? Maybe i need to add an extra port in the kext? Maybe my DSDT needs some extra modifications? Maybe it is not possible at all(i hope not). Currently my HDMI port works. I have 1 external monitor but this connector is on the back of my laptop. If i connect a miniDP cable to DVI(also internal connector) the machines crashes or hangs with a black screen. Booting with miniDP connect gives me a KP. I hope someone can help me with this information. Thank you, Wietse.

Hello all, I have used the following guide to install El Capitan. https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/ Almost everything works but in our company we have Dell e-port replicator docking stations 2x DP 2xDVI and 1x VGA. I tried the Dual DVI or Dual DP but it does not work. HDMI is working when not docked, booting with DP connected to a monitor makes my laptop unable to boot. Almost the same problem was described in this topic: https://osxlatitude.com/index.php?/topic/8278-e6320-with-hd3000-booting-yosemite-with-dell-docking-station/page-2?hl=+e-port%20+replicator Can someone help me with this please? Update 1: DisplayPort is now working. I can even hotplug DP and HDMI and use three screens at the same time ( All internal connectors, docking is still not working but i will keep searching). At this point i don't even need the docking anymore because of my three screens, but it is my holiday break now i need to have something to do You can find some details @ post #3. Thank you. Wietse. p.s. i have the e7440 HD4400 core i7 model.
