However, for the sound itself, connect the wire (included in the product) directly from the computer to the TV (which is not the case with HDMI).
The power adapter is making a USB cable connected to the computer, so it is in all 3 files (video, power, and possibly sound) to connect to the computer.
Anyway it works and because it is the main redeeming a recent TV with HDMI would be much more costly than this that will allow me to use my old TV until she died.
In addition to the product and rather easy to use. No configuration was required and connections are more intuitive with indications "in", "out", "VGA" ... the adapter.
Everything is included in it including scart adapter then unnecessary to buy one. I had done and he did absolutely nothing.
