Why does HDML-Cloner Pro Helper only display a black screen?

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 will be fixed.
