Whether big or small, setting up the projector properly is vital. One of the first things you’ll want to consider is the throw ratio: that’s how far the projector needs to be from the screen to get a particular image size.
You can work this out by looking at your projector’s manual (or, usually, on the manufacturer’s website). It looks like a number, followed by a colon, and then another number. For example, if the number is ‘1.15:1’, then for a one-metre wide picture your projector needs to be 1.15 metres back, for two metres it’s 2.3 metres back, and so on.
While most projectors are ‘long-throw’ – they need to be relatively far from the screen – others are ‘short-throw’ and can be positioned quite close to the wall and still project a large image. Whether you want a short-throw or long-throw projector should be taken into consideration before buying – it’s a lot easier to buy a different projector than it is to buy a new home cinema room!
You’ll also want to consider getting a projector screen. In fact, we’d go so far as to say a screen is vital if you want the best out of your new projector. While you can certainly use a blank wall if you want to, projector screens are specifically designed to be more reflective, so you can get a sharper, more colourful picture using one instead of your standard wall.
Also, having a solid black frame around your video that the screen provides can significantly improve contrast levels.
