Setting The Contrast Ratio; Enabling The Image Freeze - Christie GS 2K 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
the black levels in the projected image while electronically increasing the gain in the
image. The result is enhanced detail and increased contrast ratio of 6500:1.
• Speed—Adjusts 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—Sets the strength of the dynamic contrast adjustment. The value ranges from
0 to 3, the higher the value the stronger the correction.
• Level—Adjusts the light source when the brightness level of the current content gets
lower than the set value. The value ranges from 50 to 100, indicating 50% to 100% of
the constant brightness. The higher the value, the larger the range to adjust the light
source.
• Real Black—Turns off the laser light while projecting black content.
• Lights Out Timer—Sets a timer for the laser light to turn off after detecting black
content.
• Lights Out Signal Level—Sets 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.
• Reset to Default—Resets all contract enhancement settings to the default factory
defaults.
