Why does OBS Studio only display a black screen with ClonerAlliance Flint 4KP Plus?

For Windows users:

  1. Please check if you got the black screen problem with HDML-Cloner Pro Helper first, Some computers need to install driver under the setting of “Video Mix Render7”, which causes the problem. Don’t worry. Please adjust the setting of “Video Mix Render7” to “Internal YUV Render” in HDML-Cloner Pro Helper, and it may work.

  1. If the solution above doesn’t work, both HDML-Cloner Pro Helper and OBS don’t display any video. We advise you to change another USB port on your computer. If a USB 3.0 port doesn’t work, you may test a USB 2.0 port.

  2. If HDML-Cloner Pro Helper displays video normally, please adjust the setting of “Resolution”, “FPS” and “Video Format” in Properties for “video Capture Device” of OBS. Please refer to the setting of HDML-Cloner Pro Helper. After configuration, OBS Studio will display video.
