Positioning your projector

Choosing a location

Your projector is designed to be installed in one of two possible installation locations:

1.Floor in front of screen; or

2.Floor at rear of screen

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your

equipment.

I.Floor front: Select this location with the projector placed near the floor in front of the screen. This is the most common way to position the projector for quick setup and portability.

II. Floor rear: Select this location with the projector placed near the floor behind the screen.

Note that a special rear projection screen is

required. Set in the Advance > Mirror menu after you turn the projector on.

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size.

The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the projector's native aspect width. This will result in a proportionally smaller height equivalent to 75% of the

projector's native aspect height.

play area

Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed by this projector. This will be seen as darkened (unlit) bars along the top and bottom (vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a scaled 16:9 aspect image in the vertical centre of the 4:3 projection display area.

When determining the position of your projector, you should consider its intended use and input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect
