If you went to school in the 70s and 80s you will probably remember taking down notes and copying information from a board where the teacher used an overhead projector. I used to love watching her write on acetate.

You may also have watched slide presentations or movies shown using a projector of some sort. Those lessons were the best because it often took time to set up the machinery and switching off the lights after we had filed into the classroom was always kind of exciting.

Televisions and audiovisual equipment, like all technology is always expanding and improving. If you enjoy a fully cinematic experience you may find that purchasing a projector is what is going to allow you to achieve exactly that.

Projector screens usually reach about 120 inches and a lot of projectors support 4K UHD resolution. Projectors definitely enhance your home theatre experience but there are a few things to consider before making your purchase.

The room in which your projector will be used must be sufficiently dark. Most projectors these days do handle moderate ambient light due to improved technology but make sure to research this and add it to your check list.

Equally important to consider is space. You will need a large empty wall for a screen that drops down or a permanently wall mounted screen. Alternatively special projection screen paint can be used for the blank wall which must be smooth.

Be sure to plan your room furniture including allowing space for the projector and sound system, chairs and side tables for refreshments and other miscellaneous items.

The distance between the screen and projector as well as viewing distance is tantamount. Most projectors require about 10feet between the screen and projector but the distance varies. If the viewer sits too close to the screen it will ruin the experience. There are throw distance calculators available online to assist you with working out the best distance for the equipment and room you are using.

The centre of the projector lens should align with the horizontal centre of your screen but look for projectors with lens shift features in case you aren’t able to put the projector exactly in the centre.

Don’t forget about cables. Consider where and how you will run your cables so that people don’t trip over them. Cables should be run along walls or inside the ceiling.

You may need an A/V receiver because projectors only have one HDMI input and usually have fewer connection ports than TVs. It depends on how many other devices you are using in your room.

Be sure to make a list of everything you must consider and take your time finding exactly the right projector and screen for you. Once you’re sure you know what you’re doing and you plan everything properly beforehand you’ll find purchasing and installation a breeze.
