Adjusting contrast ratio via IRIS
The contrast ratio is the measurement of the difference between the brightest whites and the
darkest blacks a display can show. This projector has a very high contrast ratio which can
reveal subtle color detail not possible with projectors which have a lower contrast ratio. You
can adjust the contrast level to allow for ambient lighting levels within the room which may
affect color detail. Make sure Dynamic Black in the Color menu is set to "On" before you can
adjust the contrast ratio.
To manually adjust the contrast ratio,
• Using the remote control
1. Press IRIS. The adjustment bar displays.
2. Press to lower the contrast and increase brightness, or
press to raise the contrast and decrease brightness.
• Using the OSD menu
1. Press MENU and then press / until the Color menu is
highlighted.
2. Press to highlight IRIS.
3. Press to lower the contrast and increase brightness, or
press to raise the contrast and decrease brightness.
Selecting the aspect ratio
The "aspect ratio" is the ratio of the image width to the image height. Digital TV is usually in
16:9 ratio, which is the default for this projector, and most analog TV signals and DVDs are in
4:3 ratio.
With the advent of digital signal processing, digital display devices like this projector can
dynamically stretch and scale the image output to a different aspect than that of the image
input source. Images can be stretched in a linear manner so the whole of the image is
stretched equally, or non-linearly, which distorts the image.
To change the projected picture ratio (no matter what aspect
the source is):
• Using the remote control
Press one of the aspect ratio buttons to suit the format of the
video signal and your display requirements.
• Using the OSD menu
1. Press MENU and then press / until the Display menu is
highlighted.
2. Press to highlight Aspect Ratio.
3. Press / to select an aspect ratio to suit the format of the
video signal and your display requirements.
