This projector would be recommended for medium-to-large conference rooms if it wasn't for its very noticeable rainbow effect. While there may be some lucky individuals who don't see it, everyone we showed it to did see it. It makes the image completely unwatchable.

Despite its average picture quality in our tests, the X1160 is a suitable projector for the business person who frequently goes on the road to give presentations, or for the user who wants an inexpensive big-screen for a home theatre setup.

BenQ's PB-6110 projector offers high brightness and contrast levels, and while it offers good all-round performance, the 4:3 aspect ratio makes it better for presentations than watching movies.

Business users who are more concerned with portability than performance will probably like this projector, however this unit doesn't really stand out from the crowd.

A solid business projector, the EMP-822's size means it isn't suitable for those regularly on the road, but it provides good quality images and backs them up with LAN support.

The EMP-S3 provides a huge, bright image for a relatively low price.

A solid, but not outstanding business projector, InFocus' IN36 is a compact unit, but it suffers from some colour and contrast issues that, even with calibration, cannot be fully remedied.

This isn't a brilliant projector by any means, but with a little patience, it will perform well enough for most users at a competitive price.

The InFocus Work Big IN32 is perfect if you are in the market for a business projector that will get the job done while also looking sophisticated.

If you are only planning to use it to office presentations, the InFocus Work Big IN32 may suffice but keep in mind that the colours it produces are not accurate.

The InFocus Work Big IN26 is a good all-round projector that can handle a wide range of sources and has above average image quality. If you are in the market for an attractive unit with good performance, you should give this model a look.

A cheap purchase if you don't mind the noise.
