Can I daisy-chain 3 x 4K LG UltraFine Monitors with a BlackMagic eGPU?
I am considering buying 3 4k LG UltraFine monitors to daisy-chain them to MacBook Pro via the BlackMagic eGPU Pro (Vega 56). According to the Apple website, I can daisy-chain 2 x 4k monitors, but I assume it is dependent on the display adapter (or even TB3 bandwidth limitations). Can I daisy-chain 3 of them if using this eGPU?
@swisher-sweet, A Thunderbolt controller (whether in a Mac or in the BlackMagic eGPU) only has two DisplayPort inputs. This has been true since Thunderbolt 1. It's also true with Thunderbolt 4. Maybe someone will make a USB4 controller with more DisplayPort inputs.
Anyway, this means that the maximum number of displays you can connect to a Thunderbolt controller is two, whether you use one Thunderbolt port (with chaining) or two Thunderbolt ports.
With the Blackmagic eGPU Pro, you can chain two displays to the Thunderbolt 3 port, and connect a third display to the DisplayPort port using a Belkin Charge and Sync cable.
I guess AMD doesn't make the Vega 56 anymore?
