new LG Ultrafine 24" 4K eGPU options with 2018 Mac Mini
First post here, so hello!
I've currently got the new 24" LG Ultrafine monitor connect to my 2018 Mac Mini. I want to play some games on MacOS but the GPU is very weak in the MM.
I'm looking at the feasibility of adding an eGPU, but need some guidance. Does anyone know if I can grab something like a Vega 64 to add to a Razer Core enclosure, then connect the GPU to the monitor using the Moshi USB-C to DisplayPort? I think the new LG monitor can be connected via USB-C as well as Thunderbolt 3.
The Apple Store product page says it works with Macs that support Thunderbolt and Macs that only have USB-C (such as the MacBook).
I believe some people have connected the display using the Moshi cable to a GPU. If you want to add USB (to support the other features of the display such as brightness control) then use a Huawei VR 2 cable or Wacom Link Plus or Sunix UPD2018 or Delock 89582. #159
Maybe Vega 64 is overkill for a Mac Mini? I'm not sure which Razer Core you are referring to. For the Vega 64, it should be able to supply 650W (PSU max power).
You mention a setup involving a GTX 1070, HP Dock G2 and a Titan Ridge in your post on the other forum. I'm not quite sure what's connected to what and on which mac, could you elaborate?
Instead of the Huawei cable, you can use "MonitorControl" to change the brightness of the 24" LG Ultrafine while using the reversible Moshi USB-C to DisplayPort cable. You can download it from https://github.com/the0neyouseek/MonitorControl

The GPU has DisplayPort outputs connected to GC-TITAN RIDGE DisplayPort inputs, then a USB-C or Thunderbolt display can be connected to a Thunderbolt port of the GC-TITAN RIDGE.
The GC-TITAN RIDGE just needs power if you don't need USB or PCIe tunneling functionality. If you do want USB or PCIe tunneling functionality, then the GC-TITAN RIDGE needs to be connected to the computer some how via PCIe and the computer needs software (which might not exist) to enable the functionality. Currently, this means a motherboard with GC-TITAN RIDGE Thunderbolt add-in card support.
The HP Thunderbolt Dock G2 does not add anything - except a DisplayPort 1.4 MST hub. macOS doesn't support MST hubs. But in Windows, you can connect a single DisplayPort 1.4 output from a GPU to a DisplayPort 1.4 MST hub, and get two DisplayPort 1.2 outputs to drive a dual cable 5K display such as the Dell UP2715K or LG UltraFine 5K.
That test was mentioned in the posts at
