I was a long time (see above) to connect to the search for a solution to my tablet with a VGA projector to such talks with the device in your hand, can. The problem here was to find a suitable converter, as most converters operate not only the video signal or 1: 1 and then to implement parts of the screen were not shown. Not so with this device because it has a very comfortable next to the Converter Scaler: With one button, the resolution is selected, acknowledged with the other key the resolution.
With regard to the start-up I proceeded as follows: Converter connected to the projector. AllShareCast connected to the converter. Both power supplies plugged. Beamer turned on. Tablet connected to AllShareCast
Result: The whole screen was immediately rescaliert of the projector shown in a good quality since 1024 * 768 were preset!
