Setting The Contrast Ratio; Enabling The Image Freeze - Christie Inspire Series User Manual

Setting the contrast ratio

Use contrast enhancement function to raise the contrast ratio.
1. Select Menu > Image Settings > Contrast Enhancement.
2. Select the appropriate calculation method for contrast ratio:
• Dynamic Black
video sources. It improves the black level in dark scenes by reducing the light output.
• Speed—Adjust the speed of the light source correction. The value ranges from 1 to 15. A
lower value makes the correction slower and less aggressive while a higher value results
in the faster correction.
• Strength—Set the strength of the dynamic contrast adjustment. The value ranges from
0 to 3, the higher the value the stronger the correction.
• Level—Adjust the light source when the brightness level of the current content gets
lower than the set value. The value ranges from 50% to 100%. The higher the value, the
larger the range to adjust the light source.
• Real Black—Enable the function to automatically increase the contrast ratio by turning
off the laser light when black image is detected.
• Lights Out Timer—Set a timer for the laser light to turn off after detecting black
content. The set value ranges from 0s to 20s.
• Lights Out Signal Level—Set a black level value as the threshold for the Real Black
function. The value can be selected from 0 to 5, with 0 being the darkest black and 5
being the brightest.
• Lights On Threshold—Sets the lights on value to eliminate the Real Black effect. The
function is activated when the screen brightness is higher than the value of both the
Lights On Threshold and the Lights Out Signal Level. The Lights on Threshold value
ranges from 0 to 127.
• Reset to Default—Reset the function settings to factory default values.
3. To confirm the selection, select ENTER.
