Hi,
Just received this response from Customer Support’s Paul:
"the Fairphone 5 can connect to an external display via a cable supporting the HDMI Alt Mode standard.
Please note: some newer USB docking stations with HDMI output will also work but not all. The best way to check if a cable or dock works is through trial and error. You can also ask in our community forum if someone has tried your cable/dock.
As for the maximum resolution support, I would have to check internally for more details."
Now I am tempted to preorder
