Known Issues

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

  • 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 (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)
  • If LAN subnet of the host PC/server overlaps with VPN (userful-remote) subnet, it will disconnect all connected zero-client devices (11160)
  • Inside Scaling on rotated Signage Player video walls does not scale properly (11178)
Workaround: Use Outside Scaling
  • Images with odd number of pixels not properly supported on Video Walls (11196)
Workaround: Ensure images have even number of pixels
  • Control Center will make an attempt to identify frozen stations, however sometimes a station may freeze without Control Center being able to recognize it (11555)
Workaround: If a station is frozen, restart it (using "Ctrl + Alt + Backspace") and restart the host PC/server
  • The browser may report the host PC/server is running on the IP, when starting Control Center early after bootup (11562)
Workaround: The problem may fix itself automatically after a few moments. Restart browser and try again
  • 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
  • Slow USB storage transfer speeds on Linux Desktop (11612)
  • 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)
  • 3 x 3 GPU accelerated video wall can get lagged on systems without AVX2 support (11895)
Workaround: Use a host PC/server with a CPU with AVX2 support, and a 4th generation GPU or better.
  • 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)
  • 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
  • When modifying the station's name and location from Control Center, cannot use non-ASCII character (12035)
Workaround: Use 7-bit ASCII characters only
  • The Extended Support value does not show up in the Manage Licensing dialog in Control Center (12116)
Workaround: Contact your Userful representative to confirm the status of your extended support license
  • Kiosk mode toggle will not become enabled after moving 3 or more session containers away from an existing group (12121)
Workaround: Be sure to manually verify the status of kiosk mode boolean after reassigning stations to Session Container
  • 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)

Workaround: This is a cosmetic issue and will be corrected in future release.
  • If Control Center is opened via multiple browser windows, duplicate System Diagnostics alert popups (12271)
Workaround: This is a cosmetic issue and can be safely ignored.
  • 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
  • Offline stations may appear "online" under Station Mapping > Network Stations (12098)
    • Workaround: Wait for few seconds and refresh Control Center
  • Plugin/out of USB hub from a Atrust m321 zero-client device does not wake a station from DPMS sleep (12181)
