<PARAGRAPH>The control panel allows you to choose these settings from one of the existing preset configurations. If you wish, you can edit any existing preset configuration or create a new one by changing the current values and clicking <BUTTON>Apply</BUTTON>.</PARAGRAPH>

While this step is optional, it will configure your panel more closely to the settings you have chosen in your preset configuration. </PARAGRAPH>

<PARAGRAPH>To use this feature, please follow these steps:</PARAGRAPH>

<PARAGRAPH>Your panel is now calibrated. Depending on the amount you use the panel, you may need to recalibrate to maintain color accuracy. For the average user, we recommend every 1 to 2 months. </PARAGRAPH>
|
|
<NOTE><PREFIX>Note</PREFIX>To ensure that preset configurations are loaded each time a user begins an Xsession, all color managed user accounts should have the following line added to the <FILENAME>$HOME/.sgisession</FILENAME> file:</NOTE>
|
|
<EXAMPLE>
|
|
/usr/sbin/flatpanel -nogui
|
|
</EXAMPLE>
|
|
<PARAGRAPH>Upon logging into an account configured in this manner, your last active preset configuration will automatically be loaded for your system. </PARAGRAPH>
|
|
<PARAGRAPH>Without such a change, you will need to run the Silicon Graphics 1600SW Settings control panel each time you begin a new Xsession. In a multiuser environment, such a change is mandatory if each user wishes to use the flat panel calibrated to his or her own liking. Additionally, each user should perform a calibration of the panel, particularly if the room lighting or other workarea conditions differ between users. Calibration data is stored in the file</PARAGRAPH>

<SECTION1 LBL="" HELPID = "config_gamma"><TITLE><XREFTARGET ID="60601">Configuring Gamma Settings</TITLE><PARAGRAPH>The gamma of a display describes the relationship between the video input signal level and the light output or intensity displayed on the flat panel. The Silicon Graphics 1600SW flat panel has an uncorrected gamma value of 1.8. Based on your work environment and how you use your display, you may want to choose a different gamma value. This gamma setting can be varied from 1.0 to 3.0.</PARAGRAPH>

<PARAGRAPH>To change the gamma setting, enter your preferred value in the gamma text field, then click the <BUTTON>Apply</BUTTON> button.

<NOTE><PREFIX>Note</PREFIX>The Silicon Graphics 1600SW Settings application automatically searches for the brightest intensity setting when color temperature is adjusted.
