Christie LHD878-DS Projector Review-SPECIAL FEATURES: HDBaseT and 3G-SDI, Content Over IP, Network Management Tools, DICOM Simulation, Split Screen
If you need to run a video signal hundreds of feet, the LHD878-DS offers two solution:
The ability to transmit content over IP is a useful in many applications were computers and projectors are networked — for example in business settings or schools. In the past, the only way to show content from a computer or video source on a projector was to physically connect them. This feature makes it easier to project content from a laptop on one side of the room on a LHD878-DS located on the other.
The LHD878-DS can also access and display images directly over the network. The LiveViewer software is designed for Windows users. Mobile devices (iOS and Android) can also be utilized via Christie QuickConnect. You can access content from PCs and mobile devices. To wirelessly connect the LHD878-DS to a network, an optional wireless (2.4GHz and 5GHz) module is required. This is a useful feature for classrooms, video conferencing environments, houses of worship, training rooms, etc.
You can control a LHD878-DS using a compatible web browser. There are two types of interface available, “Projector Web Control” and “Crestron e-Control®” which is a 3rd party control system. Both allows you remote access the projector and the ability to control things like focus, zoom, shift and test patterns.
The Christie also offers software tools so you can apply Geometric Correction, or fine tune Edge Blending on multiple projectors without having to reach for a remote control.
In addition to basic control, you can check the status of a single of multiple networked projectors and perform various projector operations from your computer. You can also select individual projectors or projector groups to check detailed information such as the usage hours of the projector light source, the current input source and any current errors or warnings.
You even set up a networked LHD878 projector to send you an e-mail alert if there is a problem.
The Christie LHD878 has a DICOM simulation color mode which is designed to present medical images – such as X-rays, CAT-scans, MRI’s PETs etc.
DICOM Simulation is not intended to be used as a substitute for original medical films or an actual DICOM display. However, it does deliver enough quality to be used in classrooms, medical schools and medical conferences as a tool for training doctors, nurses and technicians.
While split screen is a common feature found on many business projectors, it is still worth discussing. The LHD878-DS can project two sources in two similar-sized windows (PbyP) or you can also make one window larger than the other (PiP).
Unlike many projectors claiming split screen, both sources can be live content (i.e. video). Once you have selected the two desired video inputs, you can quickly switch the images from left to right, change the sizes, and switch which sound source to output.
