How can I troubleshoot if my dual monitors cannot achieve 4K@60Hz simultaneously?

This might be due to the bandwidth limitation of the laptop. You can take the following steps:

What can I do if my monitor cannot reach 8K@30Hz?

1). Ensure that the monitor is connected to HDMI2 port alone.

When HDMI2 connected, why does the laptop freeze when the resolution is adjusted to 8K@30Hz and HDR is turned on?

This is related to the memory of the graphics card. Generally, it is not recommended to enable HDR at 8K@30Hz. In addition, if there is a freeze at 4K@60Hz, please also turn off HDR .

When I connect to 2 monitors with Mac, why do both monitors show the same image?

When Mac is connected to dual monitor devices, the docking station can only support extending one display, and another display can only copy the display you extended, which means it only supports AAA or ABB

Why does the docking station get hot when working?

When the product works at full load for a long time, the power increases and the temperature rises. 0C - 50C is a normal and reasonable range. This is normal for all hubs and is not a quality issue. Please feel free to use it.
