Userful System Diagnostics is a great way to check your system. System Diagnostics helps to identify the potential source of an issue and provides first steps to try and resolve it. If there is problem you will see one or more notifications on the top right corner of Control Center. You can either close the notifications, learn more about the issue or take an action to resolve the issue.
You can run System Diagnostics from Control Center > Help and Support > System Diagnostics
There are several types of System Diagnostics, detailed below.
Licensing status prompt you if your host PC/server is not licensed. It also specify the number of stations if host PC/server is licensed.

Host PC/server Hardware
Your Userful install checks if the host PC/server’s hardware is adequate for optimal performance and best user experience. Following are various tests perform by system diagnostics tool on the host PC/server hardware.
- Host CPU:
- For video wall’s optimal performance, minimum 4 CPU cores are required. This is to provide enough CPU power to render the content.
- Host GPU:
- Userful Network Video Wall™ uses GPU to render and decode the content. Also, where possible provides GPU acceleration that is why an Intel® 4th-generation GPU (or better) is required.
- Host RAM:
- A minimum 4 GB memory is required by Userful Network Video Wall™.
- Host Disk Space
- Minimum 5GB is recommended to load the OS and sample content. However, if you are planning to play large media files you will need larger disk size.
- System Diagnostics tool checks if all zero-client are running at full speed (1000 Mb/s) and if the host PC/server is connected to a gigabit ethernet connection. Userful requires this to make sure that network doesn’t become bottleneck while pushing the content to the displays.
- By default all zero-clients and host PC/server gets the IP address from DHCP server. If there are more than one DHCP servers in the network there might a conflict and your Userful install checks for that to warn you. If you see the Duplicate DHCP server error you need to make sure that there is only one active DHCP server in the network.
- Note: Routers can also act as DHCP server.
- If System Diagnostics tool finds two devices with one IP address, it will warn you with "Duplicate IP Address detected" message. If you are using DHCP server (that is set by default) to assign the IP address to each device, restarting the zero-client should fix it. If you have assigned the IP addresses manually, you need to correct for it from Network Stations page under Control Center
Zero Client Health
If Control Center warns you about the health of specific zero-client(s), you need to power cycle them. You can do that after saving your work and closing your session.
Your Userful install checks for the unsupported peripherals connected to the zero-clients and warns you if it finds one. As an example you may be see "Unsupported USB hubs/devices detected." if you have plugged in a keyboard with builtin hub. If you see such a message, it is highly recommended to remove the unsupported device(s).
If your Userful install requires a third-party software to enhance the support or functionality of the product, you will see an alert notification in the Control Center, e.g. Userful Network Video Wall™ recommends to install extra codecs to support a wide range of video and image formats.
