U2723QE, S2721QS, macOS daisy chain

Your title states S2721QS yet your body states S2722QC. The S2722QC does NOT have DP in port. The S2722QC has two HDMI in ports and one USB-C.

This configuration would certainly work on a Windows OS Laptop =

Windows OS TB/USB-C out port --> U2723QE USB-C to USB-C cable --> U2723QE #5 USB-C in port --> U2723QE #6 DP out port --> U2723QE DP to DP cable --> S2721QS #4 DP in port

It is unknown by Dell if it will work in macOS. Check with Apple users on the Apple Forum. Why? Because none of the S series monitors are tested/validated by Dell in macOS.

Is it possible to disable the 90W charging?
* No. It is automatic.

After some research, I learned that the following combo does not support a daisy chain for MacBook M1/M2 Pro.

Hello,

I have a DELL S2722QC monitor which I connect to a MacBook M1/M2 Pro through an HDMI cable. I am considering buying a U2723QE monitor to daisy chain with the first monitor.

I would like to daisy chain in the following order: 

MacBook Pro TB/USB-C out port --> U2723QE USB-C to USB-C cable --> U2723QE #5 USB-C in port --> U2723QE #6 DP out port --> DP to DP cable --> S2721QS #4 DP in port

Please advise if it will work.

Thanks in advance!

Although I have purchased a U2723QE monitor, it's unfortunate that it lacks a Thunderbolt port. For a MacBook Pro daisy chaining is only supported over a genuine Thunderbolt cable to a genuine Thunderbolt Display as the first display. I have tested by myself and have also pinned some of the references below.
