No, the USB-C ports on the Satechi USB-C Multiport MX Adapter do not support video output, so a USB-C or Thunderbolt display cannot connect through them. Use the HDMI ports to connect external displays.

• The USB-C PD port, marked with a lightning bolt symbol, is for pass-through charging. The port provides up to 85W of output with a 100W power adapter.
• The USB-C data port, marked "SS", is for data transfer up to 5Gbps.
• One HDMI port supports up to 4K at 60Hz and the other supports up to 4K at 30Hz.
• The 4K at 30Hz HDMI port requires the InstantView app from SiliconMotion. See the user manual for installation steps.
