Then vain connection attempts on Smartphone and tablet Samsung Alcatel Tab3 because no jack connector does. Besides it's a 2 in 1, algebra question fingers!
I finally found a device that corresponds to a decision, my bridge Sony. I plug on the TV, and nothing. In reading the comments of Thierry, I am inspired by spring and a nice HDMI cable reinforced Amazon Basics. Miraculously, no! just a good cable, the image appears on the TV. The thin and long cables, this bit please, but it's not working or wrong. Conductor thin, almost no insulation recalls that a cable acts like an antenna and picks whatever he can catch.
The only useful part is the connection 2 in 1 plug gold. The cable is disqualified. Too bad because the concept had he really been 3 in 1 and quality would have made universal. Buy only fitting Informed use.
15 days later: I connect a DVD player to a new TV. The HDMI cable with the required length what was my joy to see that the flows transiting correctly. This cable can in some batches have an incompatibility with taking 2 in 1.
