Proof of concept of LG 5K display working on a Hackintosh! Still work to be done.

Just finished my build after having to RMA my mobo to get the BIOS flashed for 7th gen Intel processors, thanks Gigabyte. (hopefully using the right flair, this is some awesome info on what's coming next for hackintosh abilities with the new Apple software and hardware)

Here's the photo album, with some directions pointing to what cords do what: http://imgur.com/a/VK2zS

Build Specs:

Mobo: Gigabyte Z170X - Designare

SSD: Samsung M.2 1TB

GPU: GTX 1080Ti

RAM: 32GB VIPER (idk the Mhz)

If anyone has any suggestions to get this working better, I'd love to hear and try it out.

The Designare Mobo has a special Mini-DisplayPort In port to send display out of Thunderbolt 3. I had to install Windows first on a second monitor connected directly to the GPU and run Gigabyte's Thunderbolt 3 firmware update. However - right now the hackintosh won't recognize thunderbolt devices, and I believe that's because of my system definition.

After that, the LG monitor worked totally fine. It posts the Gigabyte BIOS screen, Clover, and worked at 5K on Windows. No problems on boot.

With OS X, it was a different story. I actually had the installer running on the LG display itself, but of course, no NVIDIA drivers, so it was the OS X graphics driver with only 7MB when you checked "about this mac." I can't remember for sure but I think it was recognizing it as thunderbolt until I ran Multibeast and set system definition to Mac Pro 2010.

I kept trying to switch to the NVIDIA driver, but then the display would light up black, then shut off. It wasn't until I plugged in a second display that I was able to run the NVIDIA driver, turn off login password, and set SwitchResX to automatically set the resolution for the LG display. I can't adjust the resolution inside of System Preference's display options.

I have a 2015 macbook (no Thunderbolt 3) and was using an adapter previously, and could get HiDPi on the display no problem. I was using a thunderbolt 3 to 2 adapter.

I am 99% sure that the LG display is being recognized as a DisplayPort monitor, hence the limit of 3200x1800, and no HiDPi.

Camera, Audio, and Microphone do not work. It's not recognized as a thunderbolt device.

I have seen on the TonyMacx86 forums that someone got it running at full 5K with thunderbolt. I'm going to try changing my system definition and see if that activates thunderbolt 3.

Yes, it's a lot of trial and error, but even at 3200x1800, I'm happy, it's much better than the Apple LED display, the colors and crisp "retina" view of the 5K are awesome for video editing. It can only get better from here.

I can continue with updates - I also have an Ivy Bridge hackintosh (UP5-TH) with thunderbolt 2 that I'm going to try and pipe out via the Thunderbolt 3 to 2 adapter.
