TM
—Enable the function to automatically adjust the contrast ratio for
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.
