Video Projector

A video projector takes a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, and home theatre applications.

A video projector may also be built into a cabinet with a rear-projection screen (rear-projection TV, or RPTV) to form a single unified display device, now popular for “home theater” applications.

Common display resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels).

Video Projectors are a great value in presenting to a large venue.


Computer Classroom Furniture Considerations

Room arrangement flexibility is usually better than a fixed formation. A fixed arrangement should allow focused sight lines for instruction (viewing projector screen) and small groups for interaction for a blended learning approach.

A flexible arrangement might include tables with casters for mobility and the use of WiFi to reduce the need to be tethered.

Mobile technology, such as laptops, iPods and PDAs might be considered, along with docking for these devices in the furniture, if only for charging.
