Hi, I have tried to connect my Yoga C930 to some projectors at school. So far it worked fine in one classroom on one campus but failed in several classrooms in another campus. In the latter case, even I pressed Windows key and P and chose duplicate, nothing showed up on the projector screen. Then I saw a student using X1C6. I asked him to try. He just plugged in the hdmi cable from the podium to to his laptop and images showed up on the projector screen immediately. So, it means it is not the problem with the projector but problem with my machine or USB-C to HDMI adapter. I can use the same adapter to connect a former X1Y3 to the TV at home. It worked fine. Using the same adapter and same TV with the C930, it does not work. Anybody knows what is wrong?
