I have two U2723QE monitors, connected via USB-C to a Surface Book 3. I am struggling to get the daisy chaining to work properly, as the SB3 is capable of DP 1.4 Alt mode and 2 x 4k60 yet only one monitor seems to be able to be set at 60hz. MST is enabled, and they do support this, but somethings not quite right.
Display Stream Compression and MST are very different things.
Display Stream Compression will allow one DisplayPort connection use less bandwidth for the display - allowing for higher refresh rates, resolutions, or to share bandwidth for faster data. MST is a technology that lets you chain one monitor directly to another.
Macs do not fully support MST, so if you attempt to set it up the best you'll get is a mirroring of the first display on the second display. A similar technology, Thunderbolt Daisy Chaining, will let you connect monitors in sequence, but then the monitor has to support Thunderbolt. This monitor does not.

That's frustrating. That's my precise concern that I will run into even if I can get the picture to work.
