Digital projectors have many uses. In the office, projectors will display presentations on a wall or screen for a group of people to view at an important meeting. They can also be used to create a theater experience in the comfort of your home. Instead of watching movies or playing video games on a small television, you can view them several times larger with the help of a digital projector. Some projectors are better than others for these purposes.
Instructions
1. Make sure the digital projector has connections for the hardware with which you intend to use it. To hook it up to a computer, make sure that it has a monitor jack. Ensure the projector has inputs for HDMI, composite and component cables if you're using it for your home theater.
2. Consider the purpose of the digital projector when you choose a resolution. Office presentations featuring simple graphics or words do not need a high resolution. If you're interested in high-definition gaming or HD movies, pick a digital projector with a resolution from 720p to 1080p.
3. Buy a projector with a brightness based on where you intend to use it. Large conference rooms or auditoriums need a brightness of more than 3,000 lumens, while an in-home entertainment room should have a brightness level between 1,000 and 3,000 lumens.
4. Pick a digital projector with an adjustable lens. This way, you can change the focus of the unit to improve the contrast of the projected image without moving the projector itself. This is especially important for smaller rooms or areas with limited places to mount the projector.
5. Consider the price of replacement lamps when picking out a digital projector. The light bulb inside the unit will only last between 2,000 and 4,000 hours of use before needing replacement. As of 2010, prices usually ranged from $250 and $1,000 for replacement lamps. Buy a digital projector that provides inexpensive lamps to save money in the future.
