Connect monitors to new Surface Laptop

[kration]

I've got a work MS Surface Laptop (I think it's a Surface 2) which I connect to 2 monitors:

1. Philips Brilliance S272B, via the magnetic surface adapter port and dock, then a USB-C to the monitor. This monitor then acts as a hub to other peripherals including printer, network connection etc.
2. Benq GL2460 from the mini-displayport via an adaptor to the DVI-D on the monitor.

I've tried daisychaining the Benq monitor from the Philips before with no success (via HDMI or displayport on the Philips - not sure which).

I'm now getting a MS Surface 5 15" laptop, but this doesn't have a mini-displayport.

I think the Philips will now connect via the USB-C, not via the Surface Connect Port.

Can anyone advise on how to connect the Benq?
