OK ...you got your PowerPoint presentation fine-tuned and ready for court, but how are the jurors going to see it? You're going to need a LCD Projector. Here are a few tips to make the process easier to deal with.
Projectors come in all sizes and shapes. Suitable projectors range from $500 to $5,000 and beyond. Beware, at the lower end of the price scale image quality generally suffers. If purchasing here are some factors to consider.
- Weight
Consider a lighter model if you have to carry it to court often. If you have cooperative staff this may not be a worry. What you often gain in portability you may lose in brightness.
- Brightness
Units of brightness are measured in ANSI (American National Standard Institute) lumens. Generally, projectors run between 500 and 2000 lumens. The more lumens the brighter your presentation will be. Above 2000 lumens is considered high-performance and can get you into expensive territory. Don’t go below 1000 lumens
- Contrast
The higher the contrast ratio, the greater the projector's ability to show subtle colour detail and operate in a well lit courtroom. This may become important when showing photographs. Look for contrast ratios over 500:1. A ratio over 1200:1 is considered high contrast giving you crisp, vibrant colours.
- Resolution
This refers to the clarity of the picture produced by your projector and is usually quoted using two numbers, i.e. 800 x 600, where the first number is the number of pixels from side to side across the screen, and the second the number of pixels from top to bottom.
A pixel (a distorted shortening of picture element) is the most basic unit of an image – the dot. The more pixels the better – the more pixels the higher the price.
Resolution is also quoted in letters i.e. SVGA – Super Video Graphics Array or XGA – eXtended Graphic Array.
The resolution of your projector will be no better than your computer’s resolution. Therefore it’s best if the projector resolution matches your laptop screen resolution, which for newer models is XGA or 1024 x 768 and up. Unless you have an old laptop consider a projector with XGA resolution, which will give you clearer images, especially for small photographic details.
- Fan Noise
Older and less expensive projectors have fans that make a lot of noise which can interfere with the court recording system and worse: the tier of fact’s hearing. Get a projector that’s quiet – this may be more costly but worth it. It’ll avoid the court recorder having to tell you to move the projector to the far and inconvenient side of the court room.
