We have the UD-5900 set up on 17 laptops without any issues where the laptops are closed and users only work on wireless keyboards/mice and dual monitors. One of the setups, however, has been freezing consistently when the user steps away to go perform a task or stops using the system for a brief minute.
When this occurs, even opening up the laptop and trying to move the mouse via the trackpad or use the laptop keyboard does not respond. The monitor screens show the content that is frozen and the laptop monitor screen stays black.
The laptop lid is closed and the user is working on a keyboard and mouse on two monitors.
All users have the same monitors and laptops with the same configuration.
Troubleshooting steps already taking:
Reinstalled the latest DisplayLink software which updated the existing one.
checked to make sure no HP updates were required.
Bypass the dock: If we connect the Laptop directly to a monitor and close the lid, therefore bypassing the docking station completely, the issue does not occur and was tested for two weeks without any issues.
We have tried different USB cables (both 3.0 and 2.0) and have seen the same results.
