The Projection Design F82 series provides 3-chip DLP technology and offers WUXGA resolution at up to 10,000 ANSI lumens for large-screen applications. ACOP optical color management enables user selectable color management, and ProNet 2.0 software automates the process while a wide range of low-dispersion lenses assures a custom installation fit. The unit is designed for high-uptime operation and changing lamps is easily performed from side access. Input connections include HDMI and HDCP-compatible DVI-D along with RGBHV on 15-pin and five-BNC terminals. The F82 also features an XPort for connection to third-party and Projection Design modules, including one for HD-SDI.
The new PLC-HF15000L from Sanyo uses four high-output lamps and a new optical engine to achieve a high brightness of 15,000 lumens and a high resolution of 2K providing full HD without any image compression. The cooling system uses a three-layer filter and provides automatic cleaning on the first layer, and there is an optional smoke filter available. The hot-swappable lamp feature allows a lamp to be changed while the projector is in operation. Additional features include constant brightness output control, an edge-blending function, and built-in color matching for use when operating multiple projectors.
The Sharp 3-chip DLP XG-P610X projector features powered horizontal and vertical lens shift, web browser control with diagnosis and auto email alerts, networked control with third-party control systems, and it can fit seven optional interchangeable lenses. It can also provide scaling and picture-in-picture for adding video images onto a data screen image. The video system generates XGA resolution and offers a range of video inputs including HDMI, DVI-D, component on five BNCs and RCA, computer on 15-pin Sub-D, and S-Video.
SnapAV offers the DF-125-AW-235 Dragonfly 125in. AcoustiWeave 2.35:1 Aspect Ratio Film Screen, which ships with an optional black scrim cloth to mount behind the unit to eliminate light refection back through the screen. The flexible PVC micro-weave screen material is angled 15 degrees on the beveled rigid aluminum frame to avoid hot spotting and the Moiré effect frequently seen on perforated screens. Speakers can be mounted directly behind the perforated screen without blocking sound.
For the most demanding projection environments such as simulation, planetarium, and museum exhibition, Sony introduced the SRX-T105 with three silicon crystal reflective display devices (SXRD) to produce a resolution of 4096x2160 at 11,000 lumens using twin xenon lamps. The lamps may be operated together or in single mode with one operating in standby for the other. Five optional zoom lenses are available along with a short-throw prime lens. The chassis is equipped with four slots for selectable input boards including analog, HD-SDI, dual-link HD-SDI, and HDCP-compatible DVI.
Vutec has a wide selection of commercial screen products for large venues, 2D, 3D, and simulation applications. Its product offerings include the Retrata-Vu Pro screen, which ranges up to 300in. diagonal in all the popular formats. This screen rises from the ground up allowing a solution where a traditional screen cannot be hung or wall-mounted. Another screen for large venues is the multiplexed SilverStar screen. This fixed wall-mounted or flown screen overcomes ambient light and less-than-ideal conditions that can be present in some installations. The screen has a gain of 6 and virtually unlimited off-axis viewing while maintaining true, brilliant colors. The more traditional wall- and ceiling-mounted screens are the Lectric I-C and Lectric III-C, which range in size up to 250in. diagonal. The Lectric II-C(self-supported fabric) and the LIV-C (tensioned fabric) can be flown from trusses or recessed above a finished or drop ceiling and range in size up to 320in. diagonal.
