Known Issues


These are the known issues with the latest release of Userful Network Video Wall™.

  • Once an Artistic Layout video wall is created and saved, you cannot switch it back to a Grid Layout
Workaround: Delete the Artistic Layout configuration and create a new video wall
  • Mapping a GPU-Accelerated Video Wall to supported session containers disables onboard station
  • Atrust m321 zero-client device doesn't properly support DVI->HDMI or DVI->VGA converters (10744)
Workaround: Use DVI monitors only on the Atrust m321
  • Images larger than 10800 x 8552 pixels may not display properly(10769)
Workaround: Keep images smaller than 10800 pixels wide and 8552 pixels tall
  • Video wall Color Calibration does not work with host PC/server (10843)
  • Color Calibration will not reapply after zero client is manually disconnected/reconnected (10861)
Workaround: Restart or reset the zero client
  • Blackmagic session container lists down resolutions not supported by the hardware (10870)
Workaround: Confirm that your HDMI source media supports the resolution and frame-rate the HDMI Capture session is configured to use.
  • HDMI audio not currently supported (10896)
  • Nvidia onboard not supported in video wall install (10916)
    • Workaround: Userful Network Video Wall is optimized for Intel® GPUs. Use a Intel® 4th generation GPU for the best results
  • Duplicate display IDs can show up in Rise Vision (CMS) interface (11029)
  • When Duplicate IP address are detected in the network, the warning message displayed in Control Center is cramped (11150)
  • Inside Scaling on rotated Signage Player video walls does not scale properly (11178)
Workaround: Use Outside Scaling
  • The Show Station ID feature may not work on stations running a Linux Desktop which has been locked by the screensaver (11589)
Workaround: Unlock or disable the screensaver, then press Show Station IDs button in Control Center
  • Display Link devices not supported (11654)
Workaround: Display Link GPU does not provide adequate bandwidth to support video playback. Use an SMSC GPU based zero-client
  • TN-750 and TN-502 devices are not supported in Video Wall solution(11668)
  • Same user logged in on multiple stations cannot output sound properly (11672)
  • When calibrating a video wall, unrelated video walls will be shut down. This is required because the calibration process needs to be exclusive to the host PC/server (11868)
  • Using Blackmagic Design DeckLink Duo HDMI Capture card, transitions between HDMI capture sources can result in a flicker of 0.5 to 1.0 seconds (11918)
  • Audio playback is not supported for Network Streamer Session Container (11927)
  • Slow USB storage transfer speeds on Linux Desktop (11612)
  • Adding and removing a row in grid video wall can cause the video wall to miscalculate its sizes (11978)
Workaround: Close and reopen the video wall calibration dialog to resolve. Note that running video walls are unaffected by this problem
  • SMSC networked zero-clients connected to fast ethernet switch may get a black screen when changing session containers (12005)
Workaround: Use a Gigabit Switch on all zero-clients and host PC/server network connections
  • Linux Desktop session container is not compatible with SELinux security extension (12139)
Workaround: Do not enable SELinux if you want to use the Linux Desktop session container type
  • Network Streamer works effectively with RTSP over UDP network, RTSP over TCP network is not supported (12234)
  • Offline stations may appear "online" under Station Mapping > Network Stations (12098)
Workaround: Wait for few seconds and refresh Control Center
  • Repeated Start/Stop of Zones in a video wall setup causes X to crash (12213)
Workaround: Reboot the host PC/server.
  • Plugin/out of USB hub from a Atrust m321 zero-client device do not wake station from DPMS sleep (12181)
Workaround: This issue would be fixed in future release.
  • Mapping multiple stations to Video Capture session container may cause kernel panic (12403)
Workaround: There is no workaround at the moment, a fix will be issued in a future release
  • If multiple YUAN capture cards are installed on a system, the order of inputs may change after reboot (12402)
Workaround: Correct the assignment from Control Center > Video Capture session container after reboot
  • Signage Player > Directory playback does not scan for new files while playing (12211)
Workaround: Restart the directory playback by unassigning the stations from Control Center > Station Mapping
  • Video Wall > Color Calibration does not persist across reboots (12264)
