The display resolution and refresh rate that PowerExpand 5-in-1 Thunderbolt 4 Mini Dock can support varies depending on the operating system of the host device and the number of connected monitors.
Due to the limitations of Thunderbolt 4 technology, this dock can only connect to up to two monitors at once via the two Thunderbolt 4 downstream ports.
When connected to Thunderbolt 4 Windows systems:
Single monitor: 8K@30Hz (7680x4320) via the Thunderbolt 4 downstream port.
Dual monitor: 4K@60Hz (3840x2160) via both Thunderbolt 4 downstream ports.
When connected to Thunderbolt 3 non-M1 Mac systems:
Single monitor: 5K@60Hz (5120 × 2880) via the Thunderbolt 4 downstream port.
Dual monitor: 4K@60Hz (3840x2160) via both Thunderbolt 4 downstream ports.
Note: Doesn't support M1 MacBooks.
