Color Temperature
Adjusts the color temperature of your monitor. The color temperature (or
white point) you select for your monitor sets the mix of red, green, and blue
light that makes the color white. This color temperature sets the foundation
for other colors on your monitor.
The color temperature of your monitor can be changed to one of the
following Kelvin temperatures: 4100 K, 5000 K, 6500 K, 7500 K, or 9300 K.
(Kelvin is a temperature scale used in scientific applications.)
Press – to decrease color temperature. Press + to increase color temperature.
Changing the color temperature changes the appearance of colors on the
screen. Lower temperature settings create reddish whites, and higher
temperature settings create bluer whites.
Overscan
Turns overscan on and off. Overscan moves the screen image as far to the
edges of the screen as possible without distorting the image. Press – to turn
overscan off. Press + to turn overscan on.
When overscan is on, you cannot make screen geometry adjustments such as
horizontal shift, rotation, and so on.
Scan Rate
Shows the scan rate of the monitor. This setting is for informational purposes
only; it’s not for adjusting the scan rate.
Degauss
Manually degausses the monitor. Press + to degauss the monitor.
