Projecting Computer Needs

If you have a media computer and use it to give presentations at work or school, you should take a little time to learn about the projectors you can connect to your system. The three common types of projectors are standard LCD, polysilicon LCS and DLP. Standard LCD projectors will be brighter than DLP, but tend to overheat faster. If you are using the projector for long presentations or back to back ones, you will start to see the picture degrade somewhere in the six to ten hour range. Polysilicon LCD projectors use three panels instead of one like standard LCD. The panels are also a better quality, resulting in a higher color saturation than LCD. DLP (Digital Light Processing) is the most commonly use projector at the moment. DLP uses a single chip with thousand of micro-mirrors that modulate the lamp’s light and project it through the lens. Heat is prevented from affecting the picture due to the mirror configuration, thus you will not see the image degrade over time. When looking at specs for projectors, you want to pay attention to resolution for the particular model, depending on the size screen you need and the size of the audience. Also pay attention to brightness. A rule of thumb is the brighter the room the brighter a projection lamp you will need.
