Hey,

My MacBook Pro does not connect to two external Monitors via USB-C. The Monitors are LG 4K 27" Monitors. If I connect one of them, it works. If I connect two, it works if the integrated Display is closed. If I connect both and have the Laptop open, the monitors start blinking and in random intervals the monitors show a picture for a fraction of a second. In the beginning, it fixed itself after a few minutes. Now it does not find a “sable” view with all three monitors working. Restarting macOS, connecting the monitors with a closed lid, and then opening the lid after a few minutes helps. But this seems too complicated to do a few times a day.

I tried all suggestions I found (different Cables, different ports,...)

Does anyone have a suggestion?

Best,
Johannes
 
While I am not experiencing this particular issue, I am experiencing new issues in 13.0.1 using my Caldigit TS4 dock connected to 2 4K monitors properly waking and restoring the previous display arrangement and resolutions. One of my 4K displays is an LG 27". Seems there could be a new bug around waking displays.
