Can I connect my USB-C Thunderbolt Display?

Keep in mind that the USB-C ports on the hub adapter do not support video output. The port with the lightning bolt symbol is meant for pass-through charging (up to 85W with a 100W power adapter). The second port with the "SS" label is for super-speed data transfer (up to 5Gbps). For any external display connections, be sure to use the included HDMI ports.

Can I connect my DisplayPort/VGA/DVI-to-HDMI conversion cable to the HDMI port?

We highly recommend using a direct HDMI-to-HDMI cable connection. Most conversion cables and adapters do not always work properly with the internal chipset of our hub adapters.

What is the standard temperature for this hub when all ports are in use?

We can confirm that the standard and expected temperature of this hub will vary from 85-125 degrees F depending on the quantity and types of peripherals connected to the hub at a time. Our hub adapters are BUS-powered and include active chipsets that will power themselves once connected to your computer. When all ports are in use, it is expected for the adapter to get hotter than usual due to it being pushed to its limits. We encourage users to disconnect the adapter from the host device whenever it is not in use.

Does Instant View support the Night Shift mode on the second screen?

Unfortunately not, Silicon Motion (InstantView) software does not support the Night Shift mode or any other Blue light reduction.

Will I be able to use all ports simultaneously?

Yes, you will be able to use the USB-C data, USB-C passthrough, 2x HDMI, 3.5 Aux port, Ethernet, and card slots at the same time. Keep in mind, you will only be able to use 1 card slot at a time (SD or microSD) due to its "sandwich/stacked" layout.
