I am responsible for updating and ensuring the Onelan boxes are running correctly throughout school on the TV's. We have in total 8 TV's running off this system dotted around school. They work through an ethernet cable from the server room to the individual boxes and then from the boxes through a VGA cable onto the TV. My experience with this system is that it is fairly easy to use and also easy to learn as it is presented very simple on the interface. These TV systems allow all kinds of multimedia to be streamed onto the TV's including: All common video types, all image types (including GIF), Powerpoint presentations.
