Computer Projectors

Ideal for PowerPoint Presentations

Computer Projectors

Computer projectors have been used in office presentations for many years, but only relatively recently have they been linked up to computers to improve a presentation's effect and flow. Usually computer based presentations are produced in association with Microsoft PowerPoint, an application that is designed to help you maximize the potential of your presentation.

PowerPoint is compatible with almost any make and model of projector, but if on the off chance yours is not compatible, you will probably be able to find some software that will work as a link. Some companies even design special projectors that are designed exclusively for use with PowerPoint, giving you the opportunity to maximize the functions of the program.

In most cases, any projecting that you use your computer for will be still images or graphics, such as in a PowerPoint presentation. These demands are not particularly high when compared with a DVD projection of a Hollywood blockbuster. Therefore, you probably won't need a particularly powerful projector for your requirements to be matched.

There are basically two types of projector units. LCD projectors, which are best suited to still images and graphics, and DLP projectors (Digital Light Processing), which are best used in conjunction with video data. If you need to play videos (including DVD's) through your computer projector, then you should probably buy a DLP projector. Currently these cost around $2000 at a minimum and can cost ten times that sum for a top of the range model. However, prices are expected to fall over the next few years.

It is more than likely that an LCD projector will satisfy your needs when used in conjunction with a computer. There are various graphic options to choose from (both in LCD and DLP formats), beginning with SVGA 800x600 projectors and resulting in VXGA 1600x1200 projectors. For most PowerPoint presentations, the entry level SVGA 800x600 will normally suffice, although if you are spending a considerable amount of money on a projector, then it might be wise to make it as future proof as possible without exceeding our budget. When choosing a resolution, bear in mind the resolution that your computer operates in as it is preferable for the computer and the projector to operate in the same resolution, particularly if your monitor will be wired up to the system too. For laptops, this is essential.

If you are likely to be traveling around with your projector, it is important to purchase a highly portable model. Some projectors are even small enough to fit into the bag of a laptop, but the most important thing to consider is the weight. Ideally you shouldn't look at anything over 7lbs.
