Projector technology now has greater connectivity than ever

Projectors have progressed so much since the distant days of dusty acetate sheets on OHPs.  They now have the technology to display from the latest devices and can project a super-sized 100-inch picture on a screen or wall from just a metre away.

As well as computers, set top boxes, Blu-Ray and DVD players, you can now project straight from mobile phones and tablets, stream content from Roku, Apple TV and Google Chromecast, share photographs and video directly from cameras and camcorders, present straight from a USB stick and connect to the latest games consoles.

But it is not just the connectivity that has improved, they are designed to simply plug and play – dispelling the myth that projectors are difficult to set up.

When choosing a projector, you should look at which devices you would like to connect it with.

Multiple HDMI ports make it easy to switch between sources at the touch of a button.

MHL allows a projector to be turned it into a smart display by connecting a smartphone or tablet with a single cable to play games, stream videos and share photos on the big screen.

USB Plug and Play allows presentations to be viewed straight from a USB stick.

Most projectors have optional wireless.  This uses a WiFi dongle to allow you to connect and display presentation materials wirelessly from a laptop, PC or Mac and mobile device.

Full 3D projectors can display true 3D content from 3D Blu-Ray players, 3D broadcasting and the latest generation games consoles.

Many Optoma projectors have powerful built-in speakers which save you the cost and time of installing external speakers.  But you still have the option of connecting to external sound systems through the audio output if you want the cinema quality surround sound.

The projector is not just for offices and schools.  You can get a super-size screen at home to play action-packed games or watch TV shows, live sports and movies.  And with the short throw option allowing you to place the projector so close to the screen, it is suitable for small or large rooms.
