8.2.7 Phase
About Phase adjustment
When displaying computer patterns or graphics (RGB or YUV signals) which are very detailed (tilting, vertical stripes, etc. ), jitter
in picture (mis-sampling) may occur, causing horizontal stripes in portions of the screen. When this jitter occurs, adjust ’Phase’ for
optimum image.

8.3 Aspect ratio
Aspect ratio is greyed out when theFull Screen Representationfunction inDisplay Setupis switched ON or
when theShow Native Resolutionfunction inImageis switched ON.
What can be done ?
The aspect ratio setting forces the projector to project an image using a defined aspect ratio

DMD
Digital Micromirror Device
What can be done
The aim here is to always show the resolution of the source independently of the resolution of the DMD panels.

8.7 Color space
Color space
A color space is a mathematical representation for a color. For example, the RGB color space is based on a Cartesian
coordinate system.
What can be adjusted ?
The color space (gamut), the collection of colors which can be reproduced by the projector, can be adjusted to 3 predefined stored
values (one projector specific and 2 international standards). Acustom adjustment is possible. The maximum color space which
can be displayed is the projector color space. This color space is measured at the factory and stored inside the projector.
How to switch the color space ?
1. PressMENUto activate the menu bar.
2. Press→to select theImageitem. (image 8-25)
3. Press↓to pull down theImagemenu.
