1.8 / 2.0 / 2.4 / 2.6
For specific PC / Photo source.
Note: When Blending mode is selected, only gamma Standard2.2 is supported.
Dynamic Contrast
Set up the Dynamic Contrast to maximize the contrast for dark content.
‡ Dynamic Black: Enable this 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.
‡ Extreme Black: Enable this function to automatically increase the contrast ratio by turning off the
laser light when black image is detected.
‡ AV Mute Timer: Set a timer for the laser light to turn off after detecting black content. The set value
ranges from 0s to 10s.
‡ Black Signal Level: Set a black level value as the threshold for the Real Black function. The value
can be adjusted from 0% to 5%, with 0 being the darkest black and 5 being the brightest.
