Optoma WHD211 UK HDMI Wireless Transmitter and Receiver, White

Get your slides onto the big screen without crawling under the table for a cable with this Optoma WHD211 wireless transmitter and receiver. Plug the transmitter into the HDMI port on your laptop or tablet, and whatever's on your screen shows up on the projector at the other end of the room.There's nothing to download first, so a visiting client can pick up the transmitter, connect their own laptop and be presenting within seconds of sitting down.

The 50-60ms lag is small enough that your cursor moves on the big screen as you move it on the trackpad, and the link holds from up to 20m away, so you can walk the room while you talk instead of standing next to the display.
