Overview of 3LCD Technology Used in the Epson 705HD
What makes LCD projection technology very practical is that projectors can be made very compact, since the LCD chip is very small. Other advantages that can be implemented is high contrast and brightness capability, as well as low power consumption. This combination of factors can make an LCD projector very portable for multimedia use, such as business presentations (even in partially lit rooms). Also, video projectors using LCD technology also provide an excellent option for home theater use.
3LCD refers to a technology used in many video projectors that employs 3 LCD chips (one for each primary color: green, blue, and red) to produce an image.
The way 3LCD works is that single white light source is split into three colored light beams. These beams, in turn, lights up and passes through the three LCD chips, which now display a green, red, or blue image. Next, these images are combined through a prism, and then, using a lens, a full color image is projected onto a screen.

Setup and Installation
The Home Cinema 705HD is easy to set up and use.
After setting up a screen (size of your choosing), position the unit on a table or rack at the optimal distance from the screen or white wall(your choosing). Note: The Home Cinema 705HD does not have a ceiling mount option.
Starting up the projector is easy. First, plug in your source (such as a DVD or Blu-ray Disc player) to the proper video input on the back of the projector. Then, plug in the power cord and turn on the power using the button on the top of the projector or the remote. It takes about 10 seconds or so until you see the Epson logo projected on your screen, at which time you are set to go.
At this point, you can raise or lower the front of the projector using the adjustable foot, and you can also adjust the image angle on the projection screen, or white wall, using the Keystone correction function via the onscreen menu navigation buttons on the the top of the projector, or on the remote control. You can also use the manual zoom control to get the image to fill the screen properly. After this, you can use the manual focus control to sharpen your image.
