Do you hold meetings and presenter(s) need to share the screen? Usually that is not an easy task and cumbersome to say the least. BenQ has developed a new wireless technology – InstaSh0w – to share Full HD presentations from a laptop even a phone with no software set up. You can connect to anything in moments with a HDMI input.
Here is a link to the unit on their site – https://www.benq.com/en-us/projector/accessory/wdc10.html.
