It’s a challenging time for projector manufacturers, with a range of widely used video formats, new signal conveyance technology, and the analog sunset in progress. The green movement is leading the way toward lampless projection, while native HDBaseT models have already made a showing at InfoComm and falling prices on flatscreens are making the choices on smaller displays more interesting. The models we survey here have a broad range of applications, but we’ve chosen to look at their features in light of corporate boardroom and training applications.
At 6,000 lumens, the single-chip DLP CLM-HD6 projector from Barco can handle large boardrooms and corporate classrooms with its redundant 330W lamp system and 1920x1080 resolution. Installation can be customized using a range of compatible lenses and a vertical lens shift range of -20 percent to +120 percent. Training sessions can take advantage of the unit’s picture-in-picture capability for simultaneous display of two sources. Input ports on the CLM-HD6 include two HDMI, RGBHV, VGA, composite, and S-Video. It can be remote controlled by IR or RS-232 and power consumption drops to less than 2W in standby mode.
For larger corporate projection environments or for rooms with a high ambient light factor, the SP920P from BenQ can be switched to dual brightness mode for 6000 lumens using two lamps. For lower ambient light situations, such as at night in a room with lots of fixed glass, the SP920P can be run in dual reliable mode at 4500 lumens or in single alternative mode at 3000 lumens with one of the lamps as a backup. Inputs include all of the familiar analog video formats along with HDMI 1.3 and DVI. The projector also offers a presentation timer and panel lock key with password protection.
Designed by Boxlight to extend its functionality to multiple room environments where there may be a need for AV central control and monitoring, the Pro6501DP provides direct network connectivity with 6500-lumen brightness, dual lamp switching, and 10 interchangeable lens options. The filter-free unit is HDTV ready and includes power zoom and focus. It accepts all of the usual analog video formats including VGA, and it can also accommodate a DVI video source. Features include RS-232 and infrared control along with a 12V trigger port.
The REALiS SX6000 from Canon shows native widescreen SXGA resolution with 6000 lumens and a 1000:1 contrast ratio using LCoS imaging. Features include a built-in six-axis color-correction IC and 3D color look-up table. The “D” version features a DICOM simulation mode designed to reproduce medical images such as X-rays, CAT scans, and MRI images with 21-step grayscale gradation. A dynamic gamma feature optimizes gradation reproduction and contrast, which can be beneficial when displaying movies in moderate ambient light and a memory color correction feature enhances colors like skin tones and nature colors.
Network-capable and 3D-ready, the XJ-H2650 is part of Casio’s pro line, which also works with whiteboards using an optional interactive pen. The pen can be used to draw, write, click, or scroll through various applications. The 3,500-lumen projector uses a DLP imaging system and offers manual zoom and focus. The unit features 15-pin RGB and component video inputs, while remote control and monitoring are connected on a 9-pin RS-232 port. RCA connections send audio to an internal 10W speaker, and this model has USB-type A and B ports.
