Which cabling solution supports daisy-chaining multiple devices together?

The cabling solution that supports daisy-chaining multiple devices together is DisplayPort. This capability comes from DisplayPort's built-in support for Multi-Stream Transport (MST), which allows a single DisplayPort output on a computer to drive multiple monitors in a series, or "daisy-chain" configuration. Each monitor in the chain can be treated as an individual display, enabling more efficient use of output ports on the original device.

While USB, HDMI, and VGA provide different functionalities and connectivity options, they do not inherently support daisy-chaining in the same manner as DisplayPort does. For example, USB typically connects devices in a star topology rather than in a chain, HDMI lacks a native daisy-chaining capability without the use of specific devices such as HDMI switches or splitters, and VGA primarily supports point-to-point connections without support for sending data to multiple displays simultaneously. Thus, DisplayPort stands out for its versatility in multi-monitor setups through daisy-chaining.
