Optoma HD20

Optoma HD20

Introduced last fall by Optoma, the HD20 fits an economy slot with impressive performance. The single 0.65in. 1080p DMD DLP imaging, using a Texas Instruments chipset and BrilliantColor technology, produces 1700 ANSI lumens with a contrast ratio of 4000:1. The 230W P-VIP lamp is rated to go up to 4000 hours in standard mode. The manual 1.2X zoom shows an image size from 37.6in. to 301in. diagonal in a native aspect ratio of 16:9, with 4:3 and LBX compatibility. Security is provided through a Kensington lock port, security bar, and keypad lock. In bright mode, the fan noise level is 34dB, but it drops to 32dB in standard mode. The unit has ±5-degree vertical keystone adjustment and 116 percent offset capability. Video inputs include two HDMI, a VGA, component, and composite with a projection distance up to 32.8ft. A real featherweight at 6.4lbs., the HD20 may be table- or ceiling-mounted and includes a backlit remote control.

projectiondesign avielo radiance

Designed to suit larger home theater screens at a reasonable cost, the avielo radiance from projectiondesign is based on the same chassis as the spectra in the avielo line, but this DLP model uses a brighter lamp and is capable of projecting an image size up to 133in. diagonal with a resolution of 1920x1080 pixels. White point and grayscale setup is quick and simple using RealColor, projectiondesign’s color management system. Long life is built into the unit by using sealed optics to prevent dust and smoke from contacting the optical components. All of the company’s high-brightness projectors feature DuArch dual-architecture illumination with a failsafe system that allows replacement of a lamp while the projector is running on the other lamp.

Sanyo PLC-WM5500

Sanyo PLC-WM5500

The 5500-lumen Sanyo PLC-WM5500 includes a standard LNS-S20 lens but is available with five lens options to suit a wide range of installation scenarios. With a native resolution of 1280x800 in 16:10 aspect ratio, the 3-LCD unit has a contrast ratio of 800:1 and projects an image size from 40in. to 400in. It is fully networkable, has closed captioning, and incorporates the Active Maintenance Filter system, which automatically senses reduction in air flow due to clogging and advances the segmented filter to a clean area. The filter cartridge has 10 separate filter slides to allow much more time between manual filter cleaning. Video inputs include HDMI, 15-pin D-sub RGB, RGBHV on BNC connections, S-Video, composite, and component. Weighing 21.3lbs., the projector includes a 7W loudspeaker output and uses 490W power in normal mode, 406W in Eco mode.
