@li3p Thanks for getting the first of these working. I have 2 4k monitors working beautifully following your instructions. There are other issues with these machines which may impact HDMI working and those who have tried HDMI have reported problems (and never 4k resolution) but the details of what sorts of hdmi setups work are vague and I have not tried to find out.
It seems the default settings are not dependent on the bios and machines can have different uefi settings independent of bios version. And as you say the default for cfg lock is 1 but mine and others had it set to 2 - which is not an option in the valid options list!
The biggest issue to making these perfect is finding a way to turn off "Enable Legacy Roms" and if you have any ideas about that...

Thank you again, your first post was a great step forward.
No, @nicksoph, I should THANK you for making a simple post of me into this detailed guide, it was you helped more people to implement their own wonderful 4K Hackintosh , and saved their a lot of Googling time.

And I am also very eager to solve the "Enable Legacy Roms" problem. Hope you can make a progress on this some day.Good Luck!

Does anyone update to Catalina(10.15)?
I have updated to Catalina last night, everything seems ok except that the 4K doesn't work anymore.

I was able to make this work on my LG 24" 4K Model 24UD58.
A few notes.
* both CFG Lock and DVMT Pre-Allocated were 0x1 before the changes were made.
* To increase video memory to 2GB, I have to use method A, manually changing config.plist as I don't find any "PciRoot(...) entries under "Devices" showing in method B picture.
* my Apple magic mouse and keyboard were paired with Asus bt dongle. It stopped functioning after the changes were made. I then shutdown the machine, disconnect the dongle, restart the machine, plug the dongle back. Mouse and keyboard work again.

The pictures on the LCD monitor are nicer, and the texts are much more clear. I salute to you all who contribute to the instructions.

I'd also like to thank @li3p and @nicksoph for working on and figuring out this 4K via HD4600 method for the Haswell Optiplex line. This guide is very clear and well written so that anyone who follows it carefully should be successful.

I've still not upgraded to 4K yet as my excellent 1080p monitors are too new and work too well to upgrade at this point. This will help a lot of people get the benefits of higher resolution monitors without spending hundreds extra for AMD Polaris graphics cards. I've got this one bookmarked for when I finally do go to 4K monitors.
