I would really like to know how to determine the connector count, and other information about how the struct is formatted. Perhaps it can help solve some trouble with integrated graphics freezing, sleep, etc.

Connector count is in the dword at offset 16.

59120000: 00 03 03 03
591b0000: 01 03 03 03
591e0001: 01 03 03 03
59180002: 01 00 00 00
59120003: 01 00 00 00
59260007: 00 03 03 03
59270004: 01 03 03 03
59260002: 01 03 03 03
591b0006: 01 01 01 01

Assuming 16 decimal, several layouts show zero at that byte offset.
If a DWORD on macOS is 32-bit, is this a bitfield then?

Interestingly, I can't find any information about 0x5918 beyond maybe an embedded device, and I don't really know how to find anything about 0x5912 rev 3. Maybe they really have zero connectors.

Both of these only show VGA connector types. Perhaps discrete graphics only.

Some ig-platform-id have no connectors (IGPU used only for QuickSync/main display is handled via discrete graphics).
There are multiple counts there. The connector count is the byte at offset 18.
Some of the data in that dword are not completely understood.
