I have two LG 32UL950-W Thunderbolt monitors connected to my Mac Studio. They are connected by a Thunderbolt cable from the Mac to one monitor and then daisy-chain from that monitor to the other.

This works fine, and I am running 4K at 60Hz on both monitors. One is in landscape and the other in portrait.

The only annoying thing is sometimes (perhaps 50% of the time) when the Mac goes to sleep and I wake it up, the first monitor does not wake up also. The second one does, but I have to turn it off and on the first monitor to turn it on.

I checked, and power saving is NOT turned on any of the monitors.
 
If you swap the daisy-chain sequence, changing the first monitor to second spot, does the stuck-in-sleep issue stay on the same monitor, or remain on whichever display is connected as the first monitor.
 
Sorry - I forgot to update...

I dealt with the issue by installing SwitchResX, and once updated to the final Ventura, the issue has only repeated once or twice.
