Selecting the Default Value for Making Adjustments
When one of “Custom 1” to “Custom 3” is selected in “Gamma”, you can select a “Correction Value”.
Select “Correction Value”, and press the 
keys to select a correction value (setting value) as a base value for adjustment.
Normal, A, B, C, D, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, Import
When “Picture Mode” is set to “Film”:
Film 1, Film 2, Import
When “Picture Mode” is set to a value other than “Film”:
Normal, A, B, C, D, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, Import
The smaller the value, the brighter the dark areas of the image will become. At the same time, the bright areas will appear blown out.
Selecting “Import” enables you to select the gamma data created externally. The factory setting for “Import” is the same as the “Normal” setting.
You can use the projector calibration software to customize the gamma data adjustment, and import the created gamma data.

About gamma adjustment
When the gamma curve is a straight line:
The brightness and contrast of the video input will be the same as that of the video output.
Area for which the gamma curve is above the straight line (A):
Video output appears brighter than the input.
Area for which the gamma curve is below the straight line (B):
Video output appears darker than the input.
Area for which the slope of the gamma curve is steep (midtone) (C):
The grayscale range of the video output becomes wider, and the contrast increases (D D’).
Procedures for adjusting the image when gamma is set to “D”
If the image appears dark when gamma is set to “D”, it is recommended to adjust the image according to the following procedures.
While checking the overall image, adjust the setting value of “Picture Tone” in the + direction.
Focus on the bright area of the image and adjust the setting value of “Bright Level” in the + direction until the bright area appears appropriate.
Focus on the dark area of the image and adjust the setting value of “Dark Level” in the + or - direction until the dark area appears appropriate.
