Answer
The Anker 555 records one HDMI output and no multiple display support, and the manufacturer states that display is carried over HDMI only.
An 8-in-1 bus-powered USB-C hub providing HDMI, Ethernet, SD and microSD readers, USB-A and USB-C data ports and pass-through power delivery.
Full product researchNo. The recorded port list for the Anker 555 is 8 in 1, and those ports are HDMI, Ethernet, SD and microSD readers, USB-A and USB-C data ports and pass-through power delivery. There is one HDMI output in that list, the recorded HDMI output is up to 4K at 30 Hz, and no multiple display support is recorded for this hub.
The manufacturer is more direct than our record is. On the Anker product page for this model, display is carried over HDMI alone, and the hub does not carry a display signal over its USB-C ports. That is a statement about the hardware, not a gap in the documentation.
In the same category, the CalDigit TS4 does record multiple display support as a feature. Its recorded display support is up to 8K on one display on compatible Windows computers and up to 6K on macOS, with dual 6K on Apple M1 Pro and M1 Max. That is the recorded difference between the two products in our catalogue.
The record does not list which laptop models are supported, what the full display mode list is, or whether the 4K at 30 Hz figure applies at every resolution. The product page lists a 4K at 60 Hz output, which conflicts with the 30 Hz figure we had recorded, so both are shown on the product page with the conflict marked.
The same caution applies to the operating system side. No display support statement is recorded for any platform.
The port list, the display output and the statement that display is carried over HDMI only were read from the manufacturer's own product pages. That is the documented behaviour, not a confirmed result from our own use.
