Cant extend two different screens?
This hub doesnt support macOS under MST mode, please try windows system.
Cant get the 4K@30Hz resolution?
Please replace a newer 4K@30hz UHDTV or a laptop that is compatible with the DP 1.4 standard or Thunderbolt 3. Kindly note that a single display can support up to 4K@30hz, but in MST mode, dual displays can only support up to 1080p@30hz.
No picture output or the display flicker?
Please adjust the laptops output resolution to a lower setting or verify the cable connection.
Why doesn’t the product support extended display on dual monitors?
Only Windows supports MST mode and SST mode. macOS supports SST mode .
