Video Capture source casts output from any playback device (e.g. PC, Mac, Smart phone, tablet, gaming console, web cams, etc.) to a display or multiple displays in a video wall setup.

Please consider following points before using this source:

  • Supported Capture Card must be installed on the Userful host.
  • Directly connected HDCP (High-bandwidth Digital Content Protection) encrypted content will not play unless it is first run through an HDCP capable splitter.

Mapping: Creating Video Capture Source

Creating Video Capture Source

Mapping allows you to bind a specific display or a video wall to the "Video Capture" source. To create this source:

  1. Click on Mapping > New Source New Source Icon.png button. From the drop-down menu select "Video Capture" as the source type and give it a name.
  2. Select the primary Input Device from the drop-down menu.
  3. Select the "Scaling" option (default: Zoom full-screen).
  4. Enable audio only if it is required.
  5. Enter the number of pixels to be cropped from left, right, top and bottom of the captured external device.
  6. Click "OK" to complete the process.

Map Displays to Video Capture Source

Once the source is created, displays and video wall can be "mapped" or assigned by simply dragging-and-dropping the display or video wall icons to the Video Capture source.

The device output will play content on the display(s) and video wall mapped to this source.

Changes will not take effect until the "Apply" button is clicked.

Please Note: Presently, YUAN capture cards are not fully supported with Userful™ software appliance. If you are planning to install YUAN capture cards for your capture needs, please contact your sales representative or send an email to for more details.


This section outlines solution to the common problems encountered while using YUAN Capture Cards.

Color Bars when launching the display or video wall


  • YUAN capture card cannot detect any input signal
Verify that the correct device is selected while creating Video Capture source and the input device is plugged into the correct port on the capture card.

Black Screen(s) when launching the stations or video wall


  • Incorrect Color Space
Verify that the color space of the capture source is correct for your card. Please see capture cards page for details, if in doubt use YUV or YCbCr.
  • Non-broadcast resolutions not supported
If the source you're trying to capture is a laptop or PC and your display is a not a Broadcast resolution, duplicating its screen to the capture card would not work with Linux or MacOS.
Resolutions such as 1366x768, 1440x900 or 1600x900 are only supported in Windows (Windows supports cloning of displays with different resolutions). To fix this:
  • in Windows (set your desktop to Duplicate, then change the capture card resolution in the Display Settings)
  • in Linux (verify that the mirror display option is uncheked in the Display Settings)
  • in Mac (verify that the mirror display option is uncheked in the Display Settings)
This will enable your laptop to correctly detect the display resolution from the capture card.
  • Remove any and all Splitters/Switches from the set up. Connect the source directly to the capture card.
  • HDCP content not supported
Verify that your capture source does not have an encrypted HDMI feed(HDCP). Note: If it is a PC, Laptop or game console, verify that you're not playing any HDCP protected content (e.g. DVD or Blu-ray), or first run the HDMI signal through an HDCP compliant splitter before connecting it to the capture card to eliminate this potential cause.
