USB-C OTG or how to connect monitor via HDMI, ethernet and usb flash drive
There are a number of USB type-C multiport hubs:
- Kingston Nucleum
- Dell DA200
- Satechi Type-C Multi-Port Adapter 4K with Ethernet V2
- Vention H-2
- Sitecom USB-C to HDMI + Gigabit LAN Adapter CN-379
- Promate PrimeHub-C
- etc..
Which of this devices could be used for port extension of Sony Xperia XA2 plus H4133 with Salifish X on board?
they way those ports work require considerable cpu computation to compress video/audio/network streams through the usb-c port. displaylink provides linux drivers (kernel modules) for that.

As the answer bellow mentions, most of the "USB hubs with HDMI out" that you find on the market, actually rely on the USB-C "alt-modes", the capabilities of most laptop (and some smartphones) to output other things beside USB 3 via a USB-C connector.
The most well known example being Apple Mac Books, able to output Thunderbolt via their connectors. (And microUSB connectors used to the same and be able to output HDMI signal using MHL).
It happens that Sony Xperia can't do any of them. Their connector can only speak USB 3. There are no physical pins connected to the GPU as @WedgeStratos mentions, there's no way for the GPU to push display data on the port.
