The device is small and is powered by a single USB port: Beware however the AC adapter is not provided but of the phone works perfectly.
There is an HDMI input for connecting any DVD player or console and an output jack for plugging in an external speaker (not supplied cable)
The image is really good (tried on a 19 'office) and the only flaw is related to the object minimalism: no possible setting. For example it can not convert the signal to fit a 4/3 screen. On my screen so I 16/9 stretched vertically.
But it helps out well and it's mostly very discreet.
