Review on Onten VGA to HDMI VGA Adapter with VGA Splitter - Connect Computer, Laptop, PC and More to HDMI Display or Projector by Luke Liu

Works as promised for other uses. However, I'm trying to split a PowerPoint presentation on the projector and another on the BlackMagic Atem MINI PRO, but unfortunately it doesn't work. But I give 5 stars because it works for other outputs like multiple monitors. Just didn't work with my ATEM MINI PRO, although the same HDMI output I was trying to share worked on the portable TV we had.
