Optoma has released the EH200ST projector aimed at the education market which boasts built-in speakers and 2,800 lumens of brightness.
The projector has a short throw lens which gives a super-sized 100-inch picture on a screen or wall from just over a metre away. It has two HDMI inputs and can be turned into a smart display by connecting a smartphone or tablet with a single cable using MHL to play games, stream videos and share images on the big screen.
The built-in speaker delivers 10W audio and audio output is also included, enabling connection to external sound systems.
