> "USB-C 2.0" in the specs reveals that. DisplayPort Alt Mode requires at least USB 3.0, the PinePhone Pro would be a Linux phone supporting that.
That's not quite accurate IMHO, as the OG PinePhone also supports the feature, despite being USB 2.0. The fact that PINE64 only got it working in PinePhone hardware revision 1.2a maybe also reveals why few phones (whether they support USB 2 or 3.*, e.g., the Pixel 8 was the first Pixel phone to support the feature) actually support DisplayPort Alt Mode: It does not just add cost for parts, but also makes the design more complicated (and may require multiple design iterations to get right, which are expensive).
So: If DisplayPort Alt Mode or somthing like "USB-C video out" is not mentioned, you can usually safely assume that the device does not support it.
