The LCD/light module has seven different colors to chose from which are: red, dark blue, violet, green, yellow, white, and light blue. There are 2 different modes for the colors; Auto mode which automatically changes the colors every two seconds and manual mode which is one color only that you can set. The LCD/light module will display the system power status, HDD status, time, and temperature in both Celsius and Fahrenheit which is read from the thermal probe. The time button is actually the mode button, it lets you set the time, and color of the display. The right button moves between time and temperature and while in temperature the left button changes it from Celsius to Fahrenheit. The LCD is really easy to use and works really well. The thing I do not like about this display is that the time is only in military time rather than AM/PM, it would be nice to have the option to change it.
