Range: 0 to 40
Factory default setting: 20

Sharpness uses variable filtering to affect input picture detail and definition.
Increasing the sharpness setting gives the visual effect that the noise filter setting is decreasing.
Although the sharpness and noise filter settings seem to offset each other, they are actually two
different adjustments that affect two different sets of circuitry. Operators should adjust both
settings until optimal picture quality is achieved.
Range: 0 to 7
Factory default setting: 3
Operation:
Press button to increase the sharpness.
Press button to decrease the sharpness.
If the following settings seem confusing, we recommend that you experiment with the MENU,
, , and ENTER buttons until you familiarize yourself with the IN1402 front panel control
operations. It's a good idea to get comfortable using these buttons to navigate through the on-
screen menu system before moving on to other sections of this manual. If you get lost, enter
unfamiliar territory or are afraid of making an improper selection, pressing the MENU button
allows you to leave the menu system safely without making any changes. We also recommend
that, unless you're a qualified audiovisual technician, you avoid the Advanced menu.
Gamma: The 30 active gamma correction curves programmed into the IN1402 are used to compensate
for the non-linear response of many display devices. Since Gamma, Brightness and Contrast controls
interact with each other the following order of adjustments are suggested:
1. Set the brightness and contrast controls to factory default positions.
2. Adjust Gamma as desired.
3. Adjust brightness and contrast to fine tune the image.
Range: 1 to 30
Factory default setting: 10*
Operation:
Press button to step to higher numbered gamma curves.
Press button to step to lower numbered gamma curves.
* The factory default setting of 10 refers to a gamma correction curve of 1.0

Increasing the noise filter setting gives the effect that the picture sharpness setting is decreasing.
Refer to the sharpness setting section at the top of the page.
Range: 0 to 47
Factory default setting: 5
