Christie LHD878-DS Projector – Hardware Tour: Overview, Control Panel, Inputs and Connectors
The LHD878 shares the same chassis as Christie’s other DS Series projectors. While not as small as my home theater projector, The LHD878 is compact considering the unit can deliver nearly 8,000 lumens.
Dimensions, with lens removed, are: 23.0″ x 17.5” x 9.1″
It is one of most compact, mid-brightness, business projectors available. While the LHD878-DS may be relatively compact, it is solid – the chassis weighing in at 40.3 pounds (lens not included).
The LHD878-DS is not packaged with a standard lens but the projector is compatible with seven powered lenses. All the lenses compatible with the Christie LHD878-DS are motorized, and most of them provide focus, lens shift, and zoom. With that Christie provides lens memory capabilities for 3 separate savable settings, which is a benefit for many such as rental and staging companies.
Large exhausts are located on the left side of the center mounted lens area and an intake vent to the right. There’s a front IR sensor for the remote. On the top is the Christie logo and five indicator LEDs on the far-right edge.
The inputs and connectors are located along the right side of the chassis behind two removable covers.
Replaceable air filter occupies the left side of the chassis. Most of the rear of the chassis in taken up by another large exhaust vent.
The control panel of LHD878-DS is located on the right side of the chassis next to all the inputs. At the top is the Menu cursor buttons which are used to navigate the projector’s various menus. Cursor buttons are also used in conjunction with other control panel buttons to do things like switch between inputs and make lens adjustments.
Below the cursor buttons, along the left side, is an INPUT button to directly access the Input sub-menu along with a SHUTTER button to temporary blank out the screen. The STANDBY/ON button is also located on left side at the bottom.
On the right side of the control panel are the FOCUS, ZOOM and LENS SHIFT buttons to make lens adjustments.
The LHD878-DS has a wide variety of inputs which are located behind two removeable panels. Behind the first panel are most of the inputs and connections.
Starting at the top, there is a 3G-SDI coaxial input commonly used to run video long lengths (up to 100 meters) from a professional camera. Next is a standard RJ45 ethernet jack for connecting to the local area network. There is an USB input where you can connect an optional wireless adapter.
There is a DisplayPort, a RGB Computer input and a RGB Monitor output which can used to feed a second display. Note: the RGB input can also be converted into a component video input.
There is a composite video connection along with RCA audio inputs. The LHD878-DS includes Audio IN/Out mini jacks.
For control, the LHD878-DS has Remote Control In/Out jacks for hard wiring a remote in environments where infra-red is unreliable. For additional command and control capability, there is a RS-232C serial port.
Under the second cover are two HDMI inputs (with HDCP 2.2 for compatibility with 4K HDR sources). There also a HDMI Loop-Through which allows HDMI input signals – up to 4K at 60Hz – to be passed on to another projector or display device which eliminates the need for an HDMI distribution amp/splitter.
Lastly, there is the HDBaseT™ connector for running 4K video up to 70 meters over inexpensive CAT6 ethernet cable
