Userful 10.6.1 - April 12, 2021


Userful 10.6 - January 26, 2021

Userful 10.6 brings a number of exciting new capabilities to the Visual Networking Platform.

Important Notice

Users upgrading to 10.6 may encounter one of the following issues.

Zone Numbering

When creating a new Zone, there are occurrences where the numbering for the Zone does not automatically increment. To correct this, please manually input the Zone Number.

Role-Based Access Control and LDAP Authentication

We are investigating issues with user accounts not allowing logins after updating. Users with accounts created in Role-Based Access Control and with LDAP authentication should wait for updates on this issue before updating.

Blackmagic Capture Firmware Upgrades

We are investigating issues encountered after updating to the latest Blackmagic driver and applying the accompanying firmware updates for some models of capture card. Users should be prepared to completely power off their servers after updating to allow the cards to be re-enumerated on the PCI bus of the system. Waiting for updates on this issue before upgrading is recommended.

Userful On-Premise

uClient ubiquity

uClient support comes to On-Premise servers! The Userful uClient Adapter is now supported with Userful On-Premise servers as a replacement for Zero Clients.

LED wall support

You can now use a Userful On-Premise server to power a multi-controller direct-view LED wall with flawless synchronization.


You can use a Userful On-Premise server combined with uClients to deliver display signage video walls that consume minimal network bandwidth and server utilization.

More capture feeds

Through the magic of software optimizations, we have doubled the amount of Blackmagic Capture sources that a Userful system can process, with no hardware or other configuration changes needed.

  • Smooth playback of 1080p sources was capped at roughly 12, now 24 per server
  • Smooth playback of 4K sources was capped at 2, now 4 per server

These numbers are very general and can vary depending on server type and use case, and require servers with adequate PCIe capacity. please speak to a Userful Sales Engineer for assistance planning your deployment.

System Monitoring

We've added a helpful new tab to On-Premise servers that allow for at-a-glance monitoring of system resources and load, helping you to identify bottlenecks in a server that is not performing properly.

Other On-Premise Improvements

  • Added an option to view individual source names in Command & Control
  • Added a list of upcoming events to the Events screen
  • Mute and volume audio controls in Display and Zone Settings
