You will need two separate DisplayPort to USB-C cables. I had two LG UltraFine 4k 23.7" displays that were daisy-chained together by one of the TB3 cables that came with the monitors. My MacBook was able to drive both monitors with just a single TB3 cable running from the laptop to the primary monitor. For my PC, I had to use two
Moshi USB-C to DisplayPort Cables. The daisy-chain setup did not work when plugged into my graphics card's (2080TI) USB-C/VirtaulLink or DisplayPort ports nor did it work when plugged into the TB3 port of my motherboard (ASRock Z390 Phantom m-ITX).
So all I need for dual monitor use are 2 Moshi cables and no need for a thunderbolt cable to connect both monitors to each other?
I'm not fussed about needing a one cable setup. Using however many cables needed get both Ultrafine 4k to work with my Windows PC is no problem.
If I can only control the brightness of the monitor on my macbook pro 13, does the brightness stay the same if I switch to my Windows Desktop?

Thanks for the info. I was seriously considering switching my 8700k, asus z390, 1080ti for an Asrock x570 itx/tb3, 3700x and 5700xt combo just so I can use the daisy-chain feature with the asrock mobo thunderbolt port. Looks like I won't have to daisy-chain the monitors if I understood what you wrote correctly.
