specifications subject to change without notice ? digital view ltd ? doc ver 1.7: 23 april, 2014 (sgx-1920_manual.doc) page 55 of 70 appendix iv ? auto color gain the auto color gain func tion is supported in the argb mode only and is designed to calibrate the controller to the incoming video signal. in order to calibrate correctly, the display must be displaying an image containing both black and white data (see illustration below) when the function is used. the internal processor of the video contro ller chip will then execute a process to adjust the relative values of the rgb signals to achieve t he best performance. the parameters of the corrected rgb values are then stored in the controller and are unaffected by the reset factory defaults function. the reference pattern can be downloaded at : http://www.digitalview.com/suppor t/downloads/testpattern_1280.bmp this reference pattern is for 1280x1024 resolution and it needs to set your argb input source to 1280x1024 resolution before performing the auto colo r gain function. the position of the black vertical bar in the pattern at the right side is impor tant. it will affect the calibration result if you are setting the argb input to other resolution. warning - if the auto color gain is executed wit hout an appropriate image being displayed, then the process will set incorrect values and the display colo rs will be distorted. if this occurs, then it can either be corrected by performing the process correctly or if this is not possible then the reset color gain function can be used. this function will rese t the stored rgb values to a set of approximate values.
