Hi @Hervé. As promised, I have successfully increased my VRAM on my High Sierra Intel HD 5500. Maxed out the VRAM by setting the last 2 digits to 99.

I'm trying to get my external display working with DELL docking station, NOK...

 

E7240, i5 4310U, HD4400, 256GB SSD, install with 10.12, SMBIOS MBA6.2 Profile (is this correct type???), I have HDMI + DP, both ports are OK, I believe the DP is supported by the original driver since on MBA6.2 there is DP, HDMI is OK thanks to colver injection. Docking station connect to monitor with DVI cable. I have tried the all the following patch, all failed......

 

0105        1200        0002
0306        1200        0002    both port 1 and port3 change to DVI, because I don't know which port is the docking port

 

0105        0900        0002
0306        0900        0002    priority???  try anyway

 

0105        0900        0004
0306        0900        0004    both port 1 and port3 change to DVI

 

0105        0900        0002
0204        0900        0002     Try port 0204 with DVI

 

0105        0900        0008
0204        1200        0002     priority?

 

0105        0900        0008
0204        1200        0004     Try port 0204 with DP

 

0105        0900        0008
0204        0900        0004     priority?

 

0105        0900        0008
0204        0800        0004     priority?

 

0105        0900        0008
0204        0800        0002     DVI

 

0105        1200        0008
0204        1200        0100     VGA

 

0105        1200        0008
0204        1200        0400     eDP

 

I have HDMI + DP, so HDMI = 0105 and DP = 0204?? I thought the DP maybe in the same position as the DVI on you E6440 so I try to patch port 0306 at the beginning, when I put the laptop on the docking station there is NO reaction, nothing... then I try to modify port 0204, at least I have a blink on my laptop screen when I put it on the docking, looks like it detects something so I assume port 0204 is the docking output.

 

How do I know port type from IOReg? IOReg attached  DELL E7240.ioreg.zip 

For E7240, is it correct to set SMBIOS MBA6.2 profile?

 

I have HDMI + DP,  what about the docking station video output? so confuse about this, the docking port (the one on the back side of laptop) integrate with many ports, power, USB, video, Ethernet ...... should we consider this is the 3rd video port after HDMI and DP? if yes what type of connection is this?  

Should we make the patch according to the docking station--monitor connection we use? I believe the docking station - monitor connection doesn't matter, as the question above, the laptop--docking station connection type count

 

I have another laptop E6420 installed with 10.10, I get the monitor nicely working with dock station, so I try to use this AppleIntelFramebufferAzul.kext   in 10.12, it bring the output on the monitor but clearly the it's not properly dirved, VRAM 4M, monitor resolution cannot adjust, very poor video quality and so on, but I can confirm the docking station hardware and my laptop docking port are OK

 

So please, some help, thank you.

Re: DVI, I believe I had made myself clear back last year...

 

You'd be wasting your time with Azul framebuffer patching on a Latitude E6420 since that's an Sandy Bridge platform with HD3000 graphics! Please refer to existing HD3000 patching guides for that laptop.

You have have to apply the patches to your Sierra Azul kext. Do not install the posted El Capitan kext in Sierra, it will not work and will kill graphics acceleration.

 

Again, you will not get DVI as 2nd screen, that's no longer supported past early Sierra versions. You'll only get it as main output display with lid closed.

First off, you need to determine which port is HDMI by plugging in the HDMI monitor. Then post the IOReg file, so we could help you patch your file.

When I connect an HDMI to my laptop, in IOReg there are no changes, that's why I have uploaded a dump from Linux.

Please see all files upload...

  1. Your Clover config is contradictory: you've added a 4th Azul patch at the end of your Kernel & Kexts Patches section that contradicts patches of port 5 & 6 set above (and where priority is kept at 0x09 instead of changed to 0x12). You need to decide which patches you want to keep, not mix them.
  2. If the above does not fix things, try MacBookPro11,1 SMBIOS instead of MBP11,2
