Skylake : Intel HD 530: Dual Monitor not working

[jamesst20]

Hi,

Here are my specs
It's a dell precision tower.
Intel Core i7-6700
Intel HD 530
Nvidia Quadro M4000 (Removed, so IGPU only)
Chipset Intel C236 (100 series)
Intel Ethernet I219-LM
Realtek Audio ALC3861

The motherboard has 2 DP ports and 1 HDMI port. If I try each port by booting with one connector connected, they all work. A port will only work if the monitor was connected to it during the boot. That means I can't switch port once the computer is booted up.

Also, if I boot the computer with 2 monitors, I can see (in verbose) that the computer does boot entirely, but then the screen goes black before I reach the lockscreen.

If I boot with one monitor, reach the desktop and then connect a second monitor, nothing happens. No freeze or reboot, but the 2nd monitor is not seen.

I do use Whatevergeen and Lilu. I'm running the latest clover version and I did patch my (AAPL,ig-platform-id, framebuffer-stolenmem, etc.) using the HackinTool method (insert device patches in config.plist)

Does anyone have a clue?

Thank you
James

 

Edit: We were not able to get dual monitor working. I ended up buying an ASUS DUAL OC RX 480 4GB.

Thanks for the quick reply. Like I said, I already done it unless this is not what you meant:

All ports work individually if there is a reboot between them. I just can't use multiple at the same time. Doesn't it mean the connectors are fine ? 

 

I also did try this to force my HDMI connector to be recognized as HDMI (0x08). The 2 others are already recognized as DP.

				<key>framebuffer-con1-enable</key>
				<data>
				AQAAAA==
				</data>
				<key>framebuffer-con1-type</key>
				<data>
				AAgAAA==
				</data>

This sadly didn't do any difference

I would like to add (just edited first post), the Nvidia is removed from the tower.

I do not have any CSM Option on this Dell Precision Tower 3620.

Tried the flag and it doesn't seem to have any effect.

Also, it seems I was wrong, I have one DP port that isn't working.

 

HDMI Connected:

 

Top DisplayPort Connected

 

I can't tell for the 2nd Display Port as it isn't working. Note that I have to reboot between each port test. I really don't understand how I fix these connectors. I tried exchanging BUS ID from index 1 and 3 and it did not make my 2nd DP work and it broke HDMI. I also tried to only change index 3 Bus ID to 0x02, but it didn't make it work either. However I get a black screen sooner.

 

Thanks

Dell Precision Tower 3620.

Service Tag : G9L5HK2

Intel Core i7-6700
Intel HD 530
Nvidia Quadro M4000 (Removed, so IGPU only)
Chipset Intel C236 (100 series)
Intel Ethernet I219-LM
Realtek Audio ALC3861

 

I used your app RunMe to dump as much information as possible. Here is the output https://www.sendspace.com/file/nxaxm8

( I don't usually use the boot flag -cdfon. It was just a trial)

Someone with the same IGPU (but different dell computer) achieved a triple monitor.

I tried his method and ig-platform-id and same boot flags. No success either.

@MaLd0n I know you have a lot on your plate and you help all of us for free, but I can't help but notice some threads are getting answered while mine is going down on the page Does it mean you don't know or it's currently not supported with the kind of patch we have at the moment? I don't mean any harm, I am just asking.

Thank you

James
