Catalina 10.15.5 does not separate monitors
 

Catalina 10.15.5 with technet usb3dockhdv does not separate displays.

It was working ok in mojave. But since the update, it just mirrors all output screens instead of showing different screens

Hello John,

Thank you for your patience.

If you are using a 5.2.4 KEXT driver then we are aware of this mirroring issue.
Could you please verify that on our BETA application driver? You may download it from here.

Simply uninstall your present driver and then install the above one.

In case of any questions or further issues, feel free to contact us here again.

Best regards,
Jakub
