Known Issues

Following are the known issues with this release of Userful™ 8.5.

  • 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 is currently not supported for Blackmagic DeckLink capture cards (10896)
  • Duplicate display IDs can show up in Rise Vision (CMS) interface (11029)
  • 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
  • DisplayLink, TN-750 and TN-502 devices are not supported with video wall solution (11668) (11654)
Workaround: Use an SMSC-based zero-client for video demanding applications
  • 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)
  • 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
  • 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 a future release.
  • Lowering the display resolution of 1080p monitor to 640x480 may cause black screen (12562)

  • Stations mapped to Video Capture session container may take some time to start (12895)
