@Sree9 It still doesn't work. Here is a Reddit post from a month ago talking about it yet again. The only way I can think of for how @Charles27 got a "daisy chain" working is based on his reference to having DisplayLink software installed. DisplayLink allows displays to be connected via garden variety USB ports because DisplayLink uses a driver to send video as regular USB data. So I'm thinking that somewhere in the "daisy chain" as a DisplayLink adapter dongle, maybe something like this one, that was plugged into a USB data port built into the first display and provided a video output that could be run to the second display. In that setup, the cabling would look very similar to a DisplayPort daisy chain, and as long as there was a USB data path between the first display and the Mac -- which would exist over a USB-C connection -- then that second display would be detected as an independent display. But in reality, that second display is being detected through a USB peripheral plugged into a USB port that just happens to be built into the first display. That wouldn't be a DisplayPort daisy chain. And DisplayLink comes with a raft of drawbacks that can be significant for some people's use cases.
