Known Issues

Userful On-Premise

20921 - Forward and Store playback of 60FPS content on a video wall (on uClient endpoints) gradually falls out of sync. 30FPS content plays well.

20912 - System resolution on the uClient Adapter is always set to 1080p, even if a 4k display is connected. To correct this, the resolution for the display must be set manually within UCC in Display Settings.

20821 - Connecting a device to a Blackmagic card that outputs an unsupported resolution will interrupt playback of all sources. This is an upstream issue being addressed with Blackmagic.

20778 - Screen Capture does not work with uClients. This will be resolved in a future release.

20510 - Live Updates in Command & Control when viewed through Userful Manager are disabled for versions 10.4 through 10.5.1. To resolve this, update to 10.5.2 or newer.

20477 - An onboard station can appear in UCC when there is no onboard display connected. Beyond showing an onboard station, this does not have a functional impact.

20431 - In some high system load situations, displays can show a Welcome Screen when they are not configured to do so. A new process in 10.6 will update these screens to show the assigned content correctly after a few seconds if it occurs.

20359 - In some large videowall scenarios, using Screen Capture can cause displays themselves to show a black screen. This symptom goes away when Screen Capture is disabled. So far, this has been reported only once.

20227 - Moving Sources around in Command & Control could be delayed or sluggish if done over a slow connection or VPN. Ensure each user connected to Command & Control is provisioned with 50mbit/s connections to the server, though this will vary depending on the Sources being used.

20164 - If a system has both Zero Clients and uClients paired, the display ID will only show on uClient displays when Show ID is clicked.

15181 - Power-off inactive displays may not work for displays running Web Browser content.

15052 - New line & foreign characters may not work, and long messages may not wrap properly, while using broadcast alerts with Signage sources on Video Wall zones. As a workaround, do not use foreign or odd characters in broadcast alerts.

14308 - Capturing a PC with color space set to RGB may show artifacts mostly with the text on the display. This is very common due to color space preferences on PCs versus capture cards. To resolve this, change the PC's color space output to YUV.

14169 - Changing static IP address of a network interface that is providing DHCP does not update the DHCP settings. As a workaround, disable the DHCP server when changing IP address, wait until the Control Center notifies that the DHCP is fully offline, and then re-enable the DHCP server.

13387 - DVD Player source fails with Nvidia Offload support. As a workaround, disable Nvidia Offload support when using the DVD Player source.

11589 - The Show ID feature may not work on displays running a Linux Desktop which has been locked by the screensaver. As a workaround, unlock or disable the screensaver, then trigger Show ID again.

10769 - Images larger than 10800 x 8552 pixels may not display correctly in Signage Player. As a workaround, increase the slideshow time interval based upon the time required to load the file.

Userful uClient Adapter

SD Cards larger than 32GB are not recognized. Format the SD card with FAT32 instead of exFAT or NTFS.

20898 - Playback is not able to resume if the app was moved to the background or minimized. To resolve this, close and re-launch the app, or restart the device and allow the app to auto-launch. This will be resolved in 10.6.1.

20795 - Starting a uClient adapter without a network connection can result in an incorrect startup state (appearing unpaired). A network cable should always be plugged in first, or if that is not possible, power cycle the device after the network cable is connected. 20779 - 4K60 displays may fall back to 4K30 after a reboot. Use the display settings of the panel itself to set 4K60 output.

20768 - Launch Camera function with Userful Cloud servers returns trace error in Firefox. Use Chrome or the new Edge browser.

20746 - uClient Adapters do not currently support gapless video playback. To maintain sync between videos there will be a 1-2 second black screen. This will be resolved in an upcoming release.

20709 - Maximum image resolution for Signage Player (Cloud) is 1080p. This is a limitation of the media player of the device. For Forward and Store, images will be passed as a 4k video, allowing full resolution. A more complete fix will be coming soon.

20448 - Remote Control feature for Android uClient is not yet working. Connect a mouse to the adapter via USB to control the on-screen Web Browser.

20427 - If the connection is switched from Wifi to Wired after the device is paired to the Cloud server, a new instance of uClient will be generated that will ask to be paired. This is due to the different MAC address of the two network interfaces. This may cause licensing errors. Delete the extra display, un-pair the device before switching connection methods, or do not use Wifi connections (not supported at this time).

20413 - uClient Adapters paired to On-Premise servers do not yet support audio. You can still play audio from the audio-out of the server. A fix is planned for a near future release.

20289 - Using more than one external storage device at a time is not supported. Use SD card or a USB device to expand local storage if necessary, but not both at once.
