I'm having great difficulty finding kit to perform this task.
I actually want to mirror the image showing on the chartplotter on my boat to another screen/monitor by wireless means.
My plotter has a 15 pin VGA video out socket and the destination screen has a corresponding VGA in socket.
Ideally I would also like to send the image to my Acer Iconia A500 Android tablet too but this is not essential.

The kit I have seen invariably seems to either require a computer at source or has incompatible connections like USD/HDMI when I need ordinary old VGA.

Thanks.
