Other options require experimentation.
WX9100 would require a GC-TITAN RIDGE with software or firmware that probably doesn't exist to allow dual HBR3 for 6K60.
Apple & BlackMagic released a firmware update to their eGPU/Pro when the HDR Pro 6K Display was first available. It's unlikely to work through other cards + TB3 AIC without significant effort. I have found the TB3 AIC to work best inside the AKiTiO Node Duo for Thunderbolt 3 monitor output. The key is to get the AIC powered on predictably.

@soheil, the Thunderbolt 3 AIC can be powered from the PCIe slot inside AKiTiO Node Duo. It worked for me when testing with both a Thunderbolt 3 to dual DP adapter and Samsung C34J791 Thunderbolt 3 monitor.
I'm trying to drive my LG 5k (some of the first model) from my PowerColor Gaming Station with 5500XT.
I have CG alpine ridge (works successful in PC), also I have Asus Thhunderboltex 3-tr (can't test it on pc).
I tried to connect TB3 AIC in three different risers and I tried IT-GO riser with two slots as well.
But no one setup works with my LG 5k.
Could you help me, please? Maybe I need some additional power for AIC card, or should manually activate AIC?
@enotus, I had the same issue, never managed to get the riser card to initiate.... I am pretty ham fisted though.

@enotus, I don't have an LG UltraFine 5K display to test. The only thing left that I would try is connecting the Force Power signal to 3.3V. The resistors in these pictures are 8.2 kΩ.
@enotus, I'm no electrical engineer. I use the 8.2kΩ because that's what I've seen in some motherboard/laptop schematics, and because the resistor wires are narrow enough to fit in the PCIe slot holes, and to make sure there's no electrical short. That stuff I did is a work in progress. I have yet to test it - I need to add some software to enable the USB controller in the Alpine Ridge as the next step. Then maybe some software to enable the Thunderbolt ports, and then some code to reenumerate the PCIe devices.
