If you are planning to set up an HD projector, either to screen films and images in your own home, or to put on a public screening or presentation, you will need to know how to set up your system properly. Fail to do this, and you could face rather embarrassing technical hitches right in the middle of your presentation or slideshow.

The first thing to do is to choose your projector, and whilst doing so you should look at factors such as contrast ratio, screen size, brightness and picture quality. You should also look for an HD projector which has a port for a HDMI cable.

Next, you need to:

• Mount your projector on a low, out of the way coffee table or other surface, or mount it on the ceiling
• Use an HDMI cable to connect your projector to your source device (i.e. a laptop or a Blu-ray player)
• To enable sound, connect your source device to your receiver, then connect up your speakers
• Remember to tilt or otherwise adjust the projector to align the image on the screen, and focus if needed

If you need to run an HDMI cable from your source to your projector over a very long distance, you will need to invest in high performance long HDMI cables, or use HDMI cable extenders.
