Hello community, I will soon get a surface studio 2 as a working device. At the moment I only use a mobile device with docking station on 2 external monitors. Question, can I connect the monitor of the surfaces studios over the Displayport / usb-c instead of the 2 monitors? Thanks in advance for answers

I say.
Do you want to extend the Surface Studio 2 display to the 2 external monitors? (yes you can in display options) or do you want to use the surface studio display as a monitor for another system? (no you cannot). Google translate doesn't always do a good job.
**Edit**
I am not sure you can use 2 external monitors, if you can you will need something like this. Disclaimer, I don't know how well it works because Studio only has a 4 or 8 (not 16) lane PCIexpress USBC not a full thunderbolt USBc (no daisy chaining monitors).
