Questions about Gembird USB — HDMI (Typ A)

Hello :) I ordered this adapter yesterday and it was delivered today. So far so good :) I was recommended it and told that it should work with any laptop (that has this USB input). My laptop: Dell Latitude E6410 I would like to mirror my screen. Today I connected the USB adapter to my Panasonic flat screen via HDMI cable & also connected it to my laptop. My laptop recognised and installed everything. Via the Windows USB display I can see that everything has been installed and the HDMI connection is displayed. For example, when I watch a video (during the cable connection with the TV) I do not hear any sound through the laptop. That works. EVERYWHERE, the screen is NOT transferred/mirrored, neither automatically nor when I click on recognise (at screen resolution - I have Windows 7). The screen/TV is not recognised. What could be the reason for this?
