Does my 6-in-1 iPad Pro Hub support 4K60Hz or 4K30Hz

If you are wondering what version of 4K your HyperDrive supports, look no further than to the side in which the HyperDrive logo appears. If, on the opposite end of the HyperDrive logo, there is a line that says "Model: HD319B", you have the latest version and it supports 4K60Hz. If that line is not present, your model supports 4K30hz.
