Intel hd 4600 dual monitor unreported problem.

You can buy an HDMI>DVI cable that doesn't use adapters. There are many combination cables not all have to be the same either end.

Sir do you have any suggestions about my last question?

Thanks.

Get yourself a HDMI to DVI cable not an adaptor. You can find them on Amazon something like this will work fine. https://www.amazon.co.uk/dp/B00YOSA85Q/?tag=tonymacx86-21

Hi guys sorry for the delay, but I have a big update.

So I finally grabbed myself one DVI to DVI cable, to test everything without adapters as you guys suggested. I connected my 1440p benq screen via DVI and my 1080p asus via hdmi. I first booted windows and everything worked perfectly, just as my previous configuration. Then I boot Mac and I have the exact same glitch as always, only that the glitch appears on the 1440p screen and the 1080p boots correctly. Just as before, if I sleep the computer and wake it, both screens work as expected.

With this test we can see that this is not a hardware issue anymore, but a software/configuration one.

Thanks for the help.

I boot he computer, then i put it to sleep, when I then wake it up, the glitch disappears and I get both screens working perfectly.

* Previous modifications on the config.plist are disabled because they didn't solve the problem.
** I've attached two new copies of the IOReg, one with the glitch active and another one without the glitch.

You will require the Port patches. I don't have any other solutions than to just do a Sleep fix. Power management isn't implemented neither is AppleLPC which doesn't help things neither.

Okay, to implement power management I'll try to make a SSDT (https://www.tonymacx86.com/threads/quick-guide-to-generate-a-ssdt-for-cpu-power-management.177456/) but, what can I do to solve the issue wtih AppleLPC ?

Thanks.

This is a copy of my most recent config.

Thanks.

Native Powermanagement isn't implemented. IGPU is coming under GFX0 which isn't correct. Look at acpi_dsdt_patches.plist to add change GFX0 to IGPU. https://github.com/VoiletDragon/Series-9-Patches
