While DLP technology corners the market for business or classroom projectors, LCD models are far and away the most popular in the ever-growing home entertainment market. The technology provides more affordable projectors for the home consumer, while still offering many of the features of the more expensive DLPs.

So what should you look out for when considering an LCD projector? Since there are so many available, there are enormous varieties of size, shape and resolution.

What will you be using it for? Some LCD models are designed to best suit PC applications while other models – especially the HD widescreen ones – are a better fit for home cinemas.

Connections are another consideration: what will you need to plug in to the machine and will it have the capabilities? Home-use projectors have quite static lives, so being able to attach the necessary enhancements in crucial.

When it comes to image size and resolution you have to think of what your audience will be expecting. In a home cinema you may well be expecting to view 1080p on a 100 inch screen, so make sure you get as good a resolution as your budget will allow.

Light and contrast are also key concerns. Too bright and contrast can suffer, not bright enough and it is hard to see a picture. A good contrast ratio will also allow the picture to be seen better in lighter conditions.
