What You Need to Know About 1920x1200 DLP Projectors
The 1920x1200 digital light processing (DLP) projectors allow you to use your wall as an alternative to using a computer monitor or television. These projectors utilize a chip and color wheel to produce the different colors and work in cooperation with many tiny mirrors. The farther away a projector is from the screen or wall, the larger the screen will appear.
What is the difference between DLP and LCD?Both liquid-crystal display (LCD) and DLP projectors use a single lamp of white light to project the images onto a screen. LCD models use three different LCD panels that control the amount of light that passes through them. The three panels are red, green, and blue. They are combined by a prism to create the different colors that are seen on the screen. DLP types uses a chip and a color wheel to produce the red, green, and blue light. Instead of a prism, it uses a series of mirrors.

- DVI: This type of input has 24 pins that are arranged in three rows of eight. There will also be a grounding bar. This type can come in single and dual link options.
- S-Video: This input is used for standard-definition video. This type only carries the video signal. Separate cables are used for audio.
- DisplayPort: On some computers that have a DisplayPort connection, there are DLP projectors that have a DisplayPort input that can send and receive high-bandwidth video. DisplayPort inputs have 20-pin connections that can send data transfers of 8.64 Gbps along with an aux channel that can carry other information.
- Choose a video input: Select an input that is compatible with your computer or device that will be connector to the projector.

- Choose an image brightness: Select an image brightness based on where the projector and lens are being used.
- 2000 to 3000 lumens: This level is typically used in rooms where the lights will be dimmed, like in a home theater.
- 3000 to 5000 lumens: This type is used in locations such as a boardroom where the lights will be lit.
- 4000+ lumens: This type is used in larger venues such as a hall where brighter lumens will allow for visibility from farther away.
