Connecting two LG ultrafine 4k displays with daisy chain, then connect it to a macbook pro tb2 port using an adapter.

Connecting two LG ultrafine 4k display using thunderbolt 2 port on my macbook pro retina 15in, with an adapter converting tb 2 to tb 3 socket. now the issue is I'm also connecting the another ultrafine with tb3 daisy chain, that doesn't work, seems a compatibility bug to me, the audio does work though, but nothing shows up on the second screen.

MacBook Pro 15", macOS 10.15

yup, understand that should work, just felt those seems to be a firmware compatibility bug, the two displays both show up in System Information as daisy chain devices as I just check the thunderbolt info, but just the latter connected but not lighting up.


:(, maybe what you said is the only quick-fix, an expensive fix also.
