The Hitachi CP-SX5600W takes flexibility and ease of use to new levels with multiple computer and video inputs including DVI and component video, plus great new features like horizontal keystone correction and convenient panel input selection.
In Hitachi’s LCOS panel, light is reflected back through the liquid crystal by the mirrored surface of a silicon substrate containing the control circuits. Without the control circuits between them the liquid crystal elements can be placed very close together producing a smooth, natural image on screen and yielding an aperture ratio of 92% compared with 40~60% for transmissive panels.
This results in higher contrast ratio and the ability to manufacture more compact panels that achieve similar resolution and brightness. The secret of Hitachi’s original LCOS technology is the use of very narrow spacing between the plates allowing the thickness of the liquid crystal to be halved, greatly reducing response time - the thinner the liquid crystal the faster it can change state in response to control signals. This is particularly important for video with moving content where a slow response time leads to image smearing.
A number of new facilities are incorporated in the CP-SX5600 to make it easy to use and to achieve highly professional presentations. Setting up is made easier and more flexible by integrated horizontal and vertical keystone correction. With this feature image distortion can be removed even when the projector is set off to the side of the square-on position. Keystone adjustment is simply achieved using buttons on the top of the unit. In the same convenient location are input selection buttons and a display giving an instant view of which input is selected.
As shown, the projector offers virtually every input connection required to accommodate today’s media sources. Video inputs cater for composite, S-video and component video formats, all with stereo audio. On the computer side there are two analogue RGB inputs and a digital visual interface (DVI-D), again with stereo audio. Each input can be simultaneously connected and easily selected from the projector’s control panel while the image freeze feature avoids any transient on screen noise during switching. Other connectors include RGB out for a monitor display, RS232C for control by a PC and USB for remote mouse operation.
