@RehabMan, I fixed this by disabling BOTH ports with the following patch:
Comment: 0x0a260006 disable 0105 and 0204 ports
Find: <01050900 00040000 87000000 02040900 00040000 87000000>
Replace: <FF000000 01000000 40000000 FF000000 01000000 40000000>
It appears that on my specific laptop the HDMI port is attached to the discrete graphics, not to Intel HD4600. I should admit that I didn't have a chance to test HDMI yet, as I don't have any cable. So previously I just expected that it will work with 0204 port someday when I will use HDMI, if not - I will just switch to 0105 or any (12)-one. Now I see that none of them would work and both need to be disabled.
By the way, does it mean that I can use my discrete NVIDIA graphics with external display? Is there any guide how it can be implemented? I just saw you mentioned that it is possible in your FAQ, but didn't find any adequate guide yet.
You should verify your assumptions about HDMI/Nvidia in Windows.
After you verify that it it is dedicated to the Nvidia, you can pursue making it work with the Nvidia web driver..., or native Nvidia driver depending on what is appropriate. Suggest you do some research on desktop Nvidia, so you understand the difference and which driver is appropriate for your hardware.
To disable both ports you should probably also reduce the port count to 1:
